Look at the ships also: though they are so large and are driven by strong winds, they are guided by a very small rudder wherever the will of the pilot directs.

Hosea 10:4

They utter mere words; with empty oaths they make covenants; so judgment springs up like poisonous weeds in the furrows of the field. 

Titus 3:2

To speak evil of no one, to avoid quarreling, to be gentle, and to show perfect courtesy toward all people. 

Proverbs 13:1-25

A wise son hears his father's instruction, but a scoffer does not listen to rebuke. From the fruit of his mouth a man eats what is good, but the desire of the treacherous is for violence. Whoever guards his mouth preserves his life; he who opens wide his lips comes to ruin. The soul of the sluggard craves and gets nothing, while the soul of the diligent is richly supplied. The righteous hates falsehood, but the wicked brings shame and disgrace.

Proverbs 10:18-11:27

The one who conceals hatred has lying lips, and whoever utters slander is a fool. When words are many, transgression is not lacking, but whoever restrains his lips is prudent. The tongue of the righteous is choice silver; the heart of the wicked is of little worth. The lips of the righteous feed many, but fools die for lack of sense. The blessing of the Lord makes rich, and he adds no sorrow with it. 

Psalm 109:28

Let them curse, but you will bless! They arise and are put to shame, but your servant will be glad! 

Leviticus 20:9

For anyone who curses his father or his mother shall surely be put to death; he has cursed his father or his mother; his blood is upon him. 

Proverbs 30:10-33

Do not slander a servant to his master, lest he curse you, and you be held guilty. There are those who curse their fathers and do not bless their mothers. There are those who are clean in their own eyes but are not washed of their filth. There are those—how lofty are their eyes, how high their eyelids lift! There are those whose teeth are swords, whose fangs are knives, to devour the poor from off the earth, the needy from among mankind. 

Proverbs 15:1-33

A soft answer turns away wrath, but a harsh word stirs up anger. The tongue of the wise commends knowledge, but the mouths of fools pour out folly. The eyes of the Lord are in every place, keeping watch on the evil and the good. A gentle tongue is a tree of life, but perverseness in it breaks the spirit. A fool despises his father's instruction, but whoever heeds reproof is prudent. 

Words matter! Followers of Christ, please clean up your language and stop the use of profanity. It is lowly.  It is unholy. It is not an ‘art form’ nor ‘expressive’. Please give up the use of profanity for it is pleasing to God!  It shows respect and love not only to your fellow person but reverence, obedience, and love for Him who we are made in His image!

Adeptus Custodes - History & Organization

"These men are my bodyguards, their lives forfeit to the guarantee of my physical safety. Of their loyalty to me there shall be no question nor doubt. I, and I alone, shall have the authority to stand in judgement over them. No other commander shall they have in battle nor in service. None shall bar them from me and none shall hamper or stall their mission. So it is decreed!"— Ancient declaration made by the Emperor of Mankind during the Age of Strife

The Adeptus Custodes, known as the Legio Custodes before the Horus Heresy, is the Imperial Adepta responsible for guarding the Imperial Palace and the physical body of the Emperor of Mankind. It is an elite cadre of genetically-engineered transhuman warriors who are even more potent in combat than the Adeptus Astartes. They are to the Space Marines as the Emperor is to His Primarchs, and it is rumored that they were created using the Master of Mankind's own genecode. Where Space Marines represent the mass-produced genetic soldiers of the Imperium, the Adeptus Custodes are a force of individual warriors, each a bastion in his own right.

These warriors have stood in the presence of the immortal Emperor of Mankind since before the time of the Unification Wars. For ten thousand years and more, the Custodians have stood watch over their lord and master, serving as the Emperor's personal guardians and praetorian bodyguard. During the Great Crusade these resplendent warriors guarded the Emperor wherever He went and swore to give their lives to protect His. After His incarceration in the Golden Throne following the Horus Heresy ten standard millennia ago, they have taken a far more limited role in the Imperium of Man. They almost never leave Terra and only very rarely leave the Imperial Palace as they watch over their recumbent master and patrol the precincts of the Emperor's Palace, ever vigilant of threats. It is only the Adeptus Custodes who decide who may enter the Sanctum Imperialis of the Emperor at the heart of the Inner Palace, and when they may do so.

History

The Adeptus Custodes. It is a name spoken in reverent whispers, for these warriors have stood in the presence of the immortal Emperor of Mankind, and are charged with his protection. His greatness runs in their veins, undiluted by the passage of aeons. They have been called the Emperor's right hand, for they act with his authority and fight in his name. Only now, as the threat of Chaos grows ever greater and takes its dreaded toll, does that gilded hand reach out and become an eagle's claw. The Custodian Guard are the talons of the Emperor unsheathed, and they will tear the corruption of Chaos from the Imperium no matter the cost.

Near immortal are the Adeptus Custodes, for the golden elixir of the Emperor's own blood runs in their veins. Though outwardly resplendent, there is a scar upon the soul of the Custodian Guard, an inescapable disgrace that has tainted their history and lives in the heart of every warrior, from fresh inductees to veterans over a thousand years old. Clad in baroque, golden artificer armour and armed with priceless relic weaponry, the Adeptus Custodes make for a magnificent sight. They tower over mortal men; each has the statuesque physique of an ancient hero, close to nine feet in height even without his scarlet-crested helm. Yet for all their might, for all their bravery, the Custodians were unable to prevent the Emperor from falling to his traitorous son, the Primarch Horus.

For millennia, the Adeptus Custodes have formed the unyielding core of the Emperor’s multi-layered defenses. Those Custodian Guard charged with the physical protection of the Master of Mankind spend every waking second devoted to their task, refining their warrior skills and constantly testing and updating their own strategies to ensure the sanctity of the Emperor's throne. They are his last line of defense against a hostile galaxy hell-bent on Humanity's destruction. If they fail in their task, the Imperium will collapse from the inside out. Their duty is so sacred, their reputation so profound, that even Space Marines and Inquisitors kneel before them.

Though few truly realize it, Humanity teeters upon the precipice. Aliens and fiends hurl themselves against the Imperium's borders even as the rot of treachery and the mutating curse of Chaos gnaw at it from within. Under such impossible duress, Mankind cannot endure. Once, the most part of the Adeptus Custodes would have stood stoically by as the Emperor’s foes advanced upon Terra, each lordly champion stern and immobile until the foe crossed the pitch-black moat of the Sol System and hammered upon the palace walls themselves. After all, to keep vigil is the oath they swore to fulfill, and they have never abandoned it, even as thousands of worlds have burned. Now that sovereign duty has changed. In Mankind's darkest hour, a legend has emerged from the annals of history -- the Ultramarines Primarch Roboute Guilliman, an icon of authority. The coming of this legendary High Lord has galvanized the Adeptus Custodes, and after long consultation, seen them reorganized and given new life. The golden brotherhood now numbers not only guardians, but also crusaders. Alongside the anti-psykers known as the Sisters of Silence, the Adeptus Custodes bring war anew to the enemies of the Imperium. All shall learn to fear their golden warships, for they herald swift and unmerciful slaughter. These are heroes of fire and blade, and they will not stop until every threat to their immortal master lies slain.

The Firstborn

The origins of the Custodian Guard are shrouded in myth and legend. The ancient Legio Custodes were the bodyguards and sworn protectors of the Emperor and His chosen emissaries, and when the need arose, His most deadly executioners. Genetically engineered warriors of unswerving loyalty and unshakable purpose, their might and skill-at-arms was greater even than the Space Marines of the Legiones Astartes, while their weapons and wargear were uniquely potent, representing the apex of the Imperium's technology. Their history is a long one, and for centuries they have walked in the Emperor's shadow as His praetorians and the protector of His secrets.

The Legio Custodes are by many accounts the Emperor's true firstborn, prefiguring even the Thunder Warriors. They are His first genetically-engineered, psycho-indoctrinated warriors, perfected weapons crafted by the Emperor's genius from the dread lore of the Dark Age of Technology. They are in almost every measurable way superhuman: stronger, faster, more acute of senses and more resilient even than the doomed Thunder Warriors or the Space Marines who would follow them, and so far beyond the limits of an unaugmented human as to be almost godlike in comparison. Indeed, only the Primarchs and above them the Emperor Himself exceeds them in corporeal might, and to meet them in open conflict is to court death for human or alien alike.

They are rare creatures, these firstborn of the Emperor's gene-craft. Such was their psycho-physical design, and the intricacy and sophistication of the gene-craft involved, that the modifications which went into their creation required such strict biological and psychological criteria that only a mere one in many thousands of potential candidates might prove suitable for the simplest of the steps involved in the Legio Custodes creation process. Even of this small pool of candidates, survival through the decades of alchemical augmentation and psycho-memetic training were far from guaranteed. In this fact can be seen a pattern also replicated in the Space Marine Legions, only to a far more highly pronounced degree, so that while the numbers of the Legiones Astartes were prevented from growing beyond perhaps a million at their greatest strength by the limitations inherent in the means of their creation -- a paltry sum compared to the billions of others who took part in the Great Crusade -- the Legio Custodes could never, upon the available evidence, have operated on the scale of the Space Marine Legions, even if the attempt had been made for them to do so. The number of active Legio Custodes warriors has never, it is believed, exceeded 10,000. This figure was first attained towards the middle stages of the Great Crusade and maintained diligently enough that the "Ten Thousand" itself became a cognomen for the Custodian Guard in the works of the Remembrancers and the notaries of the Imperial Court since, whatever its literal accuracy.

Certainly no more than a thousand have ever been seen together at any one time, and then only once at the famous Battle of Gyros-Thravian, fought during the Great Crusade against the Ork Warlord Gharkhul Blackfang and his vast Greenskin horde. The Primarchs Horus, Rogal Dorn and Mortarion and their Legions were vastly outnumbered and close to defeat when the Emperor led an assault from His golden Battle Barge, the Bucephelus. At the head of a thousand Custodians, the Emperor struck at the very heart of the Ork horde, confronting Gharkhul atop a towering Gargant. As the Emperor decapitated the giant, black-skinned Ork, the Custodians laid waste to the warlord's prime warriors. It is said that within moments over a hundred thousand Greenskins died and the WAAAGH! was broken. Legend has it that only three Custodians fell at the battle, their names enshrined forever and engraved on the Emperor's armour thereafter.

Wrought by the Emperor's Hand

It is not an uncommon belief, even among the learned across the wide sweep of the Imperium, to suppose the Custodian Guard are themselves some variant of the Legiones Astartes -- if so crude a term might be applied, an "advanced" form, perhaps even a second, improved iteration. While this explanation might seem to fit the facts, particularly to those without intimate knowledge of the Imperium's birth pains during the final acts of the Unification Wars on Ancient Terra, it could not in fact be further from the truth.

The bloody chronicles of the Unification Wars, particularly in their earliest stages when the Emperor first rose from the nightmarish bloodshed of Ancient Terra's long night to cast down the reign of the warlords and monsters that had long carved the birth world of Mankind into a thousand slaughter-haunted pieces, are difficult now to comprehend. Many are rightly sealed from the Imperium's scholars and even the Terran Court, the dangerous truths within suppressed. But in those dark chronicles the Custodian Guard, in some form or shape, have their part as far back as any can record or those few souls who survive yet from those times can remember. Upon the pillars of the Black Manse of Nas'sau, capital of one of the earliest of the techno-barbarian holds to submit before He who was to be known as the Emperor, inscriptions record the "Lord of Lightning" coming before their warlord-kind flanked by His "four giants of crimson and gold," demanding surrender. Solar decades later, according to detailed extant records preserved in the Trans-Nordyc Akashic archives, a companion guard of thirty "Custodians", bearing Power Spears, clad in Augment-Armour and personally commanded by the Emperor, fought at the head of the newborn Thunder Legion in the assault against the formidable Maulland Sen Confederacy. One of their number is even recorded as being responsible for striking the head of the Confederation's Tyrant-Prophet from its shoulders in the aftermath of the campaign's climactic "Battle of the Red Frost".

Decades later still from this infamous battle, it would be the Custodian Guard in their hundreds, in a form akin to their most modern aspect, who would be charged with leading the cull of those same Thunder Warriors who had once served the Emperor and who had then rebelled in the wake of their forcible disbandment and internment. Only this time the Custodian Guard would be accompanied by the new gene-crafted warriors meant to replace the Thunder Warriors; the first few thousand prototype Space Marines, most of whom would go on to form the nascent I Legiones Astartes, later known as the Dark Angels. The evidence then is clear; since before the first worlds were conquered as the Great Crusade left the Sol System, since before the taking of Luna and the Treaty of Olympus, since before the Cataclysm of Ursh and the fall of the Yndonisic Bloc, before the Space Marines and before the Thunder Warriors, the Custodian Guard have walked at the Emperor's side.

Incarnate Purpose

To accomplish the ends to which the Legio Custodes were designed, not only is a Custodian's superhuman physical power honed to a razor's edge, but so also is the individual Custodian's intellect, mental fortitude and martial skill developed with ruthless application and zeal. The result is the creation not simply of a preternaturally deadly fighter or master assassin -- though they can readily serve as both -- but to create a being whose perception and apprehension of threat and how to counter it is literally beyond the natural limits of man or the powers of a machine. By means unknown and unknowable beyond the Emperor's own forbidden laboratories are the minds of the Legio Custodes programmed and fortified, filled with an encyclopedic knowledge of all the arts of death, deceit and destruction they might encounter in their duty, and how both to counter and employ them. Beyond even this their education is prodigious, for not simply the Emperor's protectors in intention, they are also made to be His companions and with Him they are armed to converse on such matters of warfare, politics and philosophy as He wished. Most importantly, their psyches are also crafted and shaped as a master gemsmith might cut and polish a perfect stone, fashioned to precise order and pattern, a pattern to which loyalty and discipline, duty and unflinching obedience to the Emperor goes deeper than blood and bone, deeper than conscious thought or unconscious desire. If at any stage in the process the merest flaw is encountered, as with the gemsmith's search of the perfect stone, the flawed subject is discarded.

The product of these amassed arts, arcane, academic and militant, is a body of warriors these living weapons make up -- the Legio Custodes itself, the Ten Thousand. As an organisation, it is in many ways both alike and unalike to the Space Marine Legions in formation and structure, a paramilitary force unique in history, inviolate in action and answerable only to the Emperor. While each Legion was, at least at conception, a highly stratified and self-contained military organisation designed to be the shock troops and principal agency of the Great Crusade, the Legio Custodes was similarly self-sufficient and self-contained, but was never armed or expected to prosecute war, but instead to utterly dominate whichever particular close battle in which they fight. Their base of operations is Terra itself and their own domains interwoven with that of the Emperor. They hold few voidships of their own, but could command by edict any such vessel of the Imperialis Armada or later Imperial Navy to their task, and in fact requisition anyone or anything within the Imperium in extremis to serve their most sacred and undaunted task; the protection of the Emperor and His works from all the foes of humanity.

Whether serving as part of a detachment acting as the destroyers of some ill-fated foe, or tasked as a bodyguard for the Emperor or some element of His household, or even where a handful of Custodians might be deployed to act as the personal protectors to an Imperial emissary or Lord Militant, they are tireless, vigilant and remorseless. They are armed, created and trained to be the match and the death of anything they might encounter face-to-face, be that human, xenos or machine, in any circumstance of single combat, counterattack to ambush or close-range assault. Again and again has history seen the Custodian Guard stand off and defeat odds that seem beyond reason or belief. It has seen them slay monsters foul enough to have been dredged up from pure nightmare, and defeat and slay assassins born of arts both dark and subtle beyond human ken. Tested again and again, be it on alien worlds before now untrodden by humanity, or within the tangled under-hives of the domains of Mankind lost to the Age of Strife, or the twisted palaces of alien warlords, the Legio Custodes proved themselves warriors of terrifying ability. Their service and their mystery has seen the Legio Custodes quickly become a legend equal in wonder and terror even to those alongside whom they served and in the echoes of whispered stories in every corner of the burgeoning Imperium. To the common soldier and Planetary Governor alike, the golden-armoured image of the Custodian Guard is a visible sign not only of the Emperor's direct protection and the embodiment of His will and agency, but also the omen of His unstoppable wrath, as personal and as terrifying in their way as the Angels of Death, his Space Marines, are impersonal and all-conquering avatars in the minds of many of the Great Crusade itself.

The Horus Heresy

After the breaking of the Orks upon Ullanor, the Emperor returned to Terra, taking his Custodian Guard with him. The seeds of doubt he left behind soon became the roots of treachery, for there is darkness in every soul, and the Ruinous Powers have always known how to exploit it. Before a single generation had passed, the insidious taint of Chaos had infected a full half of the Emperor's Primarchs, Horus foremost amongst them. These arch-traitors spread the moral decay to the Legiones Astartes they led, and the galaxy was lit with the fires of strife and civil war.

At the climax of the Horus Heresy, the Custodian Guard fought monstrosities without number, for those in the Traitor Legions powerful enough to reach the gates of the Emperor's Palace were twisted body and soul by the baleful gifts of Chaos. A thousand victories were won by the Custodian Guard, but they all turned to ash when the Master of Mankind teleported aboard Horus' flagship, the Vengeful Spirit. There, a strike force of Legio Custodes fought the fiercest of traitors to protect their master. They were found wanting. Though Horus was defeated in single combat at the last, it was at an unimaginable cost; the Warmaster cast down the Angel Sanguinius, and dealt his gene-father a mortal blow before being slain in turn. Though the Emperor's psyche remained active within his shattered body, since that day, the Custodian Guard have stood vigil over little more than a broken corpse, wizened and immobile upon a slowly failing life support system.

Reformation

Long have the Custodians worn the shroud of shame after that fateful day. In grave ceremony they donned black cloaks to symbolize the pall of darkness that had fallen over their order. The Emperor’s realm, wracked by the tempest of heresy, was reforged by those Primarchs that survived the great upheaval. Largely through the efforts of Guilliman, the Imperium's byzantine organisations were reordered in such a way as to ensure that no one faction or power could again threaten Terra. In doing so, they relinquished some of their strength. The Legiones Astartes were divided into Chapters of a thousand. The Legio Custodes, though it kept its numerical strength of ten times that number, was reforged as the Adeptus Custodes before the time of the Second Founding, becoming castellans of the Imperial Palace whose sole and solemn duty was to protect the Emperor from final death.

In the 41st Millennium, the personal sanction of the resurgent Primarch of the Ultramarines sent shock waves through the Adeptus Custodes. After ten thousand years of mourning, the Custodian Guard have cast off their black cloaks and taken to the sea of stars once more. The fires of battle will absolve them, a baptism of blood that washes away the stain of their one great failure. Now, they crusade once more against the dying of the Emperor’s light, a vengeance long-awaited finally within reach of their blades.

Role in History

Even in the days before the Heresy, it was a rare and blessed thing to see a member of the Legio Custodes, and due to the confinement of the Emperor to the Golden Throne, it has become an almost unthinkable event for a present-day citizen of the Imperium. Even during the Battle of Terra, only a handful of Custodes joined the Emperor when He made His assault upon Horus' flagship, the Battle Barge Vengeful Spirit. Since the death of Horus and the mortal wounds he inflicted upon the Emperor, the Legio Custodes, renamed the Adeptus Custodes after the Reformation of the Imperium conducted by the Ultramarines Primarch Roboute Guilliman in the early 31st Millennium, have taken a more limited role by acting solely as the protectors of the physical form of the Emperor on Terra and the primary providers of security for the Imperial Palace. The Adeptus Custodes are the Auric Mortalis ("The Golden Death"), the dread guardians and only living beings permitted to be in the presence of the Emperor unencumbered. Now ensconced deep within the Sanctum Imperialis on Terra, they continue their eternal watch over the recumbent form of the Emperor.

Despite their long vigil, the Adeptus Custodes have continued to play an important role during some of the most tumultuous times in Imperial history. The Custodians were instrumental in ending the rule of the High Lord Goge Vandire during the Age of Apostasy in the 36th Millennium. It was the actions of a few members of the Adeptus Custodes, utilizing secret passages within the Imperial Palace known only to themselves, that brought the Sisters of Battle, then known as the Brides of the Emperor, to fully realise the acts of base treason perpetrated by Vandire. After their leader, Alicia Dominica, was brought before the Emperor Himself by the Custodes through the secret passages of the Palace, she returned and executed Vandire personally for his apostasy and betrayal of the Master of Mankind.

No one knows for sure how many hidden coups, secret rebellions and misguided attempts at assassination the Adeptus Custodes have foiled. That their martial skills remain so sharp after ten thousand standard years, however, is evidence that they have not stood an idle vigil. They have been called the Emperor's right hand, for they act with His authority and fight in His name. Only now, as the threat of Chaos grows ever greater and takes its dreaded toll, does that gilded hand reach out and become an eagle's claw. The Custodian Guard are the talons of the Emperor unsheathed, and they will tear the corruption of Chaos from the Imperium no matter the cost.

Into a New Age of Darkness

The hour of action is nigh. With the surge of Chaos activity across the galaxy and the threat of eternal damnation more real than ever, the Adeptus Custodes have taken their vow of protection to its logical extreme – they will see the destruction of those forces who pose a threat to the sanctity of Terra. First amongst these are the dread hordes of Chaos. The best form of defense is attack. It is a maxim that has survived through the millennia, and with good reason. Of late, it has become the mantra of all Adeptus Custodes commanders. In conjunction with the alpha-level Astropaths and doomscryers that dwell within the Imperial Palace, these officers launch terrifyingly effective strikes at those whom they deem a threat to the Emperor’s works. More than one galactic tyrant, laying plans for a crusade that he envisages culminating on Terra itself, has found the warriors of the Emperor descending from the heavens to strike him down before he has even taken to his ships.

There are those who believe that the Adeptus Custodes stand immobilized by ritual and rote, but they are sorely mistaken. Only the Custodian Guard know what occurs behind the Sanctum Imperialis' colossal doors, and the lengths to which they have gone to keep their vigil. Their sacred task has by no means led to inactivity. Hundreds of wars have been fought by the Adeptus Custodes over the aeons -- some in Terra's defense, some in secret, and some further afield. Even when the din of war recedes, these warriors work to test and refine the protective aegis they hold before their master, sending agents into the Sol System to divine likely routes of infiltration and assassination so they can stay ahead of even the most inventive enemies. The Adeptus Custodes have long honed strategies and tactics in case they should be called upon to join the front line fight for Humanity's survival. The day of that remit has finally arrived. Primarch Guilliman has met alone with his father, the Master of Mankind, and emerged with a clear vision of Humanity united in battle.

Those Custodian Guard known as the Companions -- the three hundred warriors charged with the direct defense of the Emperor -- remain by his side, just as the colossal edifice of his palace continues to be bolstered by a standing army of golden heroes. The rest have taken to the stars. They have done so in no small force, for this majestic legion still numbers ten thousand blades and more. With the Sanctum Imperialis secure under the vigil of the Companions, the crusaders are free to pursue the war of aggression they have long desired, putting into place war strategies perfected over the centuries through fractal thought exercises, cogitator-spawned algorithms, long study and even simulated conflicts waged in hallucinariums. These give the Custodians a tactical edge that allows them to counter the enemy’s actions before they have begun.

In an effort to seize the initiative, a strike force was mustered on Terra, supported by an entire army of Adeptus Custodes. The Custodes, for long millennia the bodyguard of the Emperor, were charged with the unthinkable -- to leave His side and strike against those who would see the Master of Mankind dead. Just as a spring tightly wound uncoils with all the more force, the Adeptus Custodes have taken war to the enemies of the Imperium with extreme alacrity and vigour. It is tradition that when one of their number falls, Terra mourns, and the giant Bell of Lost Souls is rung in memoriam; with a new era of war upon them, that sonorous toll has been heard more frequently than ever. They do not fall easily, however, for they have access to the finest weaponry, and the museum-arsenals of the Imperial Palace are theirs to use as they see fit. Few post-Heresy variations of tank, aircraft or weapons systems are at their disposal, but they are perhaps stronger for it – every weapon the Custodian Guard uses to wage war has earned its place a hundred times over. Their armoured support elements were perfected when the Imperium was still in its infancy, and they remain just as potent, their machine spirits more bellicose and powerful than any latter-day equivalent. The Adeptus Custodes employs squadrons of gold-hulled gunships -- some of these are the very same craft used during the Horus Heresy, painstakingly maintained and blessed each day with sacred oils and unguents.

When a direct vector of invasion is called for, the Adeptus Custodes utilize Godstrike pattern teleportarium arrays, appearing in the midst of the fray in storms of golden light. Their spaceships have ancient translocation bays where blessed incense drifts in the chill air, each station permanently attended to by high-ranking Tech-Priestsand blessed to such a degree that even Contemptor Dreadnoughts can be teleported straight into battle. The warriors inside, their armour proof against the wrenching forces of this arcane technology, shake off their disorientation in a heartbeat before launching thunderous assaults their foes could not have seen coming.

The willpower and fortitude of the Adeptus Custodes is such that even the most fiendish sorcerers find their mental assaults rebounding from a wall of sheer conviction. The Custodians share the blood of the Emperor, after all, and their loyalty to their primogenitor is unshakable. If the Adeptus Custodes could be said to have a weakness, it is that they fight as individuals rather than squads of soldiers, as proud lions rather than cunning wolves. Each wears armour crafted to his particular physique, fights in whatever style he deems most effective, and is given free rein to attack or defend as he sees fit. This makes him a terrifyingly effective combatant -- a single Custodian can break a charging horde by himself, though he may take a few good hits in the process. To outsiders, their supreme self-confidence may seem like arrogance. They pay little heed to mortal men, and even the Adeptus Astartes are kept at spear’s length for their former transgressions. Yet the reason is a noble one. Every act, thought and deed is made for the furtherance of the Emperor's cause, and therefore the survival of the Human race. Those who stand in the way of such paragons of surety do not last long.

Exemplars of Terra's Might

There are many ranks within the Adeptus Custodes, the highest of which is that of the Captain-General. Following in the footsteps of historical titans such as Constantin Valdor, this lordly warrior is entrusted with an autonomy that eclipses that of even a Chapter Master. Occasionally chosen to serve as one of the High Lords of Terra, the Captain-General has ruled over the Legio Custodes since the order's inception, and is tasked with the solemn duty of safeguarding the Golden Throne and directing the gleaming warriors that guard it. Under his auspices are Supreme Castellans, Aquila Commanders, Shield-Captains and a dozen ranks besides.

The Custodian Guard have always fought as champions rather than soldiers. They see unthinking loyalty, such as that of a dynasty or a conventional military structure, as a weakness ripe to be exploited – after all, it was such a culture that saw the Legiones Astartes turned against their creator. Only those who win the respect of the Adeptus Custodes can hope to command them, but should such a leader unite them, their loyalty will never fade.

The Custodian Guard do not age biologically, so a veteran officer might be well over a thousand years old. As with all their kind, warriors who believe they are no longer fit for duty will bequeath their armour to the colossal Hall of Names and go abroad into the galaxy disguised under a hooded black cloak. Those crippled in battle but willing to fight on may be remade, mightier than ever, as a magnificent golden Dreadnought

Organisation and Structure

The full details of the organisational structure, disposition and regulation of the Adeptus Custodes are shrouded in secrecy as befits an institution dedicated to ultimate security. Those outside its ranks, even though they operate close to the Senatorum Imperialis and the highest levels of the Divisio Militaris, cannot hope to know more than a degree of detail which is purely observational, and likely barely scratches the surface of the no doubt byzantine Custodes. What can be outwardly observed is contained here within this account, as are the various details and titles with which the Custodian Guard openly interacts with the other organs of the Imperium's power.

The first mystery that outsiders must cope with is that of identity. The Custodian Guard are themselves effectively ageless and as unchanging as granite, and just as impenetrable to outsiders. They each profess to a given name, often a compound drawn from the lore of Ancient Terra's roll of kings and tyrants, gods and legends. Whether or not this represents some humour or deliberate irony on the Emperor's part given the Custodian's role is something that it is perhaps unwise to speculate on. Such true names they knew as part of their birth and origin are likely obliterated by the process of their creation, but the myths that have grown up around the Adeptus Custodes have long held that each Custodian Guard garners over his centuries a long list of additional names and titles grated purely by the Emperor for their deeds, history and character. Such names are held as a secret of their Order and never betrayed to others, though some myths would have it that this roll of honour is graven in hidden fashion upon their golden armour or even etched microscopically into their very bones. It was said that Captain-General Constantin Valdor obtained 932 names prior to the assault of Horus upon Terra.

In terms of structural organisation, it is apparent that the Adeptus Custodes is unique unto itself in terms of form, offering little in common with the rest of the Imperium's agency of warfare such as the Astra Militarum of the Adeptus Astartes. This is only fitting as the Adeptus Custodes, like other elements of the so-called "Talons of the Emperor," can be more accurately described as a paramilitary rather than a strategic force, neither geared nor equipped towards the fighting or winning of wars, but to its duties of protection and where needs be, execution.

Command Structure and Tactical Disposition

The overall command of the Adeptus Custodes of course lies within the purview of the Emperor directly, but serving as the head of the Order is a single officer; the Captain-General, and due to the importance of the Adeptus Custodes in the governing of the Imperium, since they always stand the closest to the Emperor, the Captain-General often holds a position amongst the ruling High Lords of Terra on the Senatorum Imperialis.

Below the absolute authority of the Captain-General lies the Custodian Tribunate; a senior cadre of perhaps ten in number, forming the Adeptus Custodes' council of war and policy. This body has the incomparable privilege of providing their services as counsel to the Emperor Himself should He so desire it, and in the matters of the security of the Imperial Palace's inner sanctums and the person of the Emperor, no higher authority exists.

In rank below the Tribunes of the Adeptus Custodes can be found the Custodian Prefectorate and the Shield Captains. The distinction between the two, not apparent entirely to outsiders, is one perhaps of seniority and function, with the title of Prefect accorded as a reward of veterancy and favor in service by the Emperor, while the rank of Shield Captain indicates an active field command over a particular detachment or deployment. Below these ranks, the Custodians seem to be peers as in the manner of a warrior caste or aristocracy, rather than links in the more familiar chain of command found elsewhere in the Imperium's armed forces. Their functional titles adapt to their chosen role and panoply of war in whichever command they have been included, with the following broad distinctions applied in communication with external forces on a tactical level, their titles drawn from various ancient sources.

The Hykanatoi

The main strength of the Custodian Guard comprises this role at any given time. They are the bearers of the spear, the bodyguard of the Emperor and the executioners of any who would offer threat or opposition to His will. They are the image of the golden-armoured warrior that is summoned in fear and awe when the Adeptus Custodes is brought to mind. Their numbers include variations of force, wargear and panoply such as the Sentinel Guard and Custodian Guard proper, as well as the elite Hetaeron Guard -- the most skilled fighters among a force of warriors whose martial skills are already well beyond human.

The Tharanatoi

Though there are few opponents that the Hykanatoi cannot deal with, they are not a rounded military force in the sense that they are not configured to deal with exigencies such as siegecraft or attrition warfare that fall outside their purview. However, the Adeptus Custodes still maintains the ability to deploy its forces as heavy shock troops should the need arise, or indeed to counter a foe that directs overwhelming force against it in high-intensity warfare. These counter-assault forces are known as the Tharanatoi, and encompass custom-modified suits of Terminator Armour optimized for use by the Custodian's superhuman frame, as well as vastly potent portable firepower such as carried by the Sagittarum Guard, whose weapons include those few dark relics known as Adrathic Weapons --disintegration beams of phenomenal destructive potential, long gathered to the Emperor's household and entrusted to no other.

The Kataphraktoi

Long before the Emperor's retreat and seclusion on Terra after the appointment of the Warmaster Horus to command His forces, the principal role of protection and defense the Custodian Guard engaged in was a mobile one. They went wherever their master did, no matter what blasted alien world or lost cityscape of ancient glory He trod. In this the elements of speed and mobility were paramount to their success, as was reconnaissance and counter-strike in lightning response to threat. Those of the Legio who specialized in such tactics and the means of employing them were called the Kataphraktoi; they flew interceptors and gunships of sublime sophistication and power, and piloted a range of repulsor-lift grav-vehicles; tanks, transports and strike skimmers, Jetbikes and interface flyers advanced beyond anything else in the Imperium's arsenal.

The Ephoroi

The division of the Custodian Guard about which the least can be said for certain, the Ephoroi were those of the Order that were tasked with covert operations, counter-surveillance and the vitally important task of simulated attack and infiltration. It was they who tested the Legio Custodes defenses and preparations just as foes would, as well as conducted their own hidden missions to dispose of potential threats within the Imperium, and enact final and sometimes utterly secret justice as the Emperor's will demanded it. There are those who have posited that where the Ephoroi ended and the powers that controlled the Officio Assassinorum began at certain junctures was difficult even for the wisest of the Lords of Terra to discern, and it is certain when they wished that the Assassins of the Temples of Terra were the Legio Custodes to command. It is clear from ancient Imperial records that the Custodians participation in the so-called Blood Games -- a series of war games in which Custodians seek to identify all of the possible ways that the Imperial Palace could be infiltrated or assaulted -- that Custodians were trained in the arts of assassination, both improvised and professional, in order to counter possible attempts on the life of the Emperor. It was not uncommon for several Custodians to be on detached duty for these Blood Games so that the Legio remained vigilant against developing threats to the Emperor's person. Furthermore it is clear that the Custodes were also well-versed in the political etiquette of Terra, and have been known to act outside of Imperial law, to infiltrate influential Imperial noble houses and to investigate any potential threats. This aspect of the Custodian mindset was advantageous, given that the Captain-General of the Order often shared a seat upon the Terran Court, which allowed him to navigate the political maneuvering of the Imperium's various organisations while still remaining an awe-inspiring warrior. It is unknown if this particular branch of the Custodians still functions in the present era of the late 41st Millennium.

The Moritoi

The smallest and most singular division within the Legio Custodes was the Moritoi; the "honoured dead who walked". Just as with the Legiones Astartes, it was possible for a Custodian Guard, having suffered injuries so terrible that even they could not recover from them but within whom the vital spark of life remained, to be interred within the cybernetic life support sarcophagus of a Dreadnought. The first of these was made while the Unification Wars were being fought, in a modified Ur-Gholem Pattern Dreadnought, the first iteration of its kind intended for use within the Thunder Legions, and as the number of Dreadnought patterns and sub-types within the Imperium's arsenal increased across the Great Crusade's decades of warfare and innovation, so too did the Legio Custodes keep pace with these developments. Though they remained relatively rare, with less than perhaps a hundred Dreadnoughts of the Legio Custodes in service at the time of Magnus the Red's folly and the subsequent attack on Prospero, they represented a phenomenally powerful concentration of force, most having had their chassis upgraded to the Achillus Pattern, a variant of the Contemptor Dreadnought manufactured with materials and technologies far beyond even the vaunted war machines of the Legiones Astartes.

Rank Structure and Formations

Captain-General of the Adetus Custodes - The senior-most officer within the ranks of the Adeptus Custodes, the Captain-General is the Emperor's most trusted companion and guardian, a watchman of inviolable purpose and all but unmatched fighting skill. Due to the singular importance of the Adeptus Custodes, who stand the closest to the Emperor in eternal vigil, the Captain-General holds a position amongst the ruling High Lords of Terra on the Senatorum Imperialis.

Shield Captain - The rank of 'Shield Captain' is a generalization used when referring to one of the senior ranks within the Adeptus Custodes, as the upper command of this elite paramilitary organisation is far from transparent to outsiders. Within the Adeptus Custodes such senior ranks range from Prefect to Lictor, Proconsul to Tribune, following the ancient patterns of Terra's lost history. Elevated both through the trust held among their peers for their judgement and skill, but first and foremost advanced by the direct approval and in some cases intervention of the Emperor Himself, these are warriors not only of consummate and superhuman ability, but also rare insight, acumen and knowledge. Afforded the rarest of and finest of the Imperium's arms, each of these legendary fighters command the Adeptus Custodes against all manner of threats against the Emperor, His works and His domains.

Hataeron Guard - Part of the inner circle of the Adeptus Custodes, the Hataeron Guard serve as the Emperor's closest protectors, aides and confidants, leaving His side rarely but for the direst of circumstances. Selected individually for their service by the Master of Mankind, they represent some of the most potent fighters in the Imperium, almost like demigods of the battlefield. During the earlier years of the Great Crusade, when the Emperor still walked amongst Mankind, the Hataeron were a regular feature upon the worlds deserving of His attention. Yet as His actions were turned elsewhere, His inner guard would follow too, becoming almost a myth in their absence. In the modern era, it is said that only 300 of these elite Custodes serve as the personal guard of the Emperor, called the Emperor's Companions. They are charged with the eternal vigil over the the Emperor's Sanctum Imperialis chambers at all times and are privileged to always be in His physical presence.

Aquilon Terminator Sodalities - These elite warriors wear Tactical Dreadnought armour, known as Aquilon armour, that was specifically developed for the ancient Legio Custodes use. Advancing yet further upon the Cataphractii Terminator armour patterns, the Aquilon pattern took into account the enhanced physique of the Custodians as being able to bear more weight and strain than even a Space Marine, and so is fitted with additional integrated power systems and capacitors which make up for some of the limitations of the origin-pattern. This enables the Aquilon pattern to retain the Cataphractii pattern's famous durability, but allows for a higher degree of speed and maneuverability the former lacks. Within the ranks of the Adeptus Custodes, Aquilon Terminator Sodalities are only employed rarely, and only as need dictates, particularly on those rare occasions where they are required to operation under conditions designated as 'Zone Mortalis' or required to storm a breach.

Sentinel Guard - Sentinel Guard Squads are the defensive formations of the Adeptus Custodes, designed to function as a mobile bulwark to protect emissaries on hazardous ground and hold defensive lines against the most grievous onslaught in open battle. In order to achieve this, they are equipped with energy field-reinforced 'Praesidium' shields -- a precursor technology to that later employed by the prototype Legio Astartes Storm Shields -- which are able to resist the heaviest weapons fire. When deployed outside the walls of the Imperial Palace, their charge is often to protect key aspects of allied detachments and resources liberated from the enemy. However, it has been witnessed during large scale sudden assaults that their close formations also served to disrupt enemy lines. While they still retain the loose unit structures of the Adeptus Custodes, the Sentinel Guard by their nature utilise a greater synchronicity between warriors in service to the various phalanx formations that could be required of the squad at any given moment.

Agamatus Squadron - The Agamatus squadrons specialize in the use of one of a number of customised grav-skimmer and and jetbike designs still utilized by the Adeptus Custodes -- the heavy duty, plasma motor-boosted Gyrfalcon Pattern as their steads in battle. The increased power of the design supports not only the heavily armoured Custodian Guard, but also allows it to mount a powerful Iliastus Pattern Bolt Cannon as its on-board armament. The Agamatus Squadrons exploit these war machines to operate both as a rapid response and suppression unit in the field. In this they operate much in the manner of the elite cavalry forces of ancient times, screening the main Adeptus Custodes force from potential encirclement, reacting quickly to blunt enemy attacks, and hunting down mercilessly any foe which breaks and flees before the might of the Adeptus Custodes, ensuring the utter extermination of the enemy.

Pallas Grav-Attack Squadron - Pallas Grav-Attack Squadrons specialize in the use of the Pallas Grav-Attack vehicle, utilizing it as a highly maneuverable hunter-killer, and for its rapid strike capacity greater than that which could be afforded by the use of ground troops alone. They often use the superior agility of these advanced vehicles to inflict devastating hit-and-run assaults on the enemy or to hunt down fleeing targets. In addition, its abilities allows the Pallas Grav-Attack Squadrons to also be used as reconnaissance units or as skirmishing forces large enough to pin or delay the enemy in place as the main bulk of the Adeptus Custodes detachments are deployed.

Sagittarum Guard Sodalities - Though less common within the ranks of the Adeptus Custodes than their peers, those warriors who comprise the Sagittarum Guard Sodalities nevertheless fulfill a number of vital roles within the Custodian's order of battle. Their art of war, in contrast to the rest of the Custodian Guard, is focused on the slaying of the foe primarily at distance and upon the devastating application of firepower on the battlefield. In addition, the Sagittarum have entered legend as the hawk-sighted sentries of the Terran walls, charged with vigilance over the external borders of the Imperial Palace in ready anticipation of attack. Through decades of duty, their ability to recall movement patterns, faces and speech even years after the original incident was honed even more so than that of their peers, and as such their enhanced ability to analyse crowds for anticipated response grew in import upon the battlefields of the Great Crusade. Their skill set was cultivated so that they could precisely exercise the greatest threats of an enemy assault, annihilating it in the actinic fire of their deadly weapons.

Tribune - During the Great Crusade and Horus Heresy eras, below the absolute authority of the Captain-General was the Custodian Tribunate; a senior cadre of of perhaps ten in number, which formed the Legio Custodes' council of war. This body had the incomparable privilege of providing their services as counsel to the Emperor Himself should He have so desired it, and in the matters of the security of the Imperial Palace's inner sanctums and the person of the Emperor, no higher authority existed. By the modern era, sadly, there were only two such positions that were still maintained by the Adeptus Custodes. One of these Tribunes served as the commander of small cadres of Custodians across the wider galaxy, taking the fight to the myriad enemies of Mankind, while the other served as the master of the elite Hataeron Guard -- the personal Companions of the Emperor -- who oversaw the security of the Sanctum Imperialis.

Prefect - The title of Prefect accorded as a reward of veterancy and favour in service by the Emperor
