#AND since camelot was the first kingdom as everyone else was still in their tribe/village stage

[justaz]

merlin au where merlin keeps excalibur and returns to camelot to serve under gwen as court sorcerer after she repeals the ban. merlin remains for years, unaging, even as gwen dons wrinkle after wrinkle and spouts grey hair after grey hair. eventually, gwen passes without an heir and since merlin holds arthur’s sigil, he ascends the throne and leads camelot for years. eventually invaders come and slaughter the people and burn the fields etc etc and merlin goes out to fight. he fights like a demon, which is what they call him with his unnatural abilities and golden eyes, and merlin chases them from his kingdom - only, they slaughtered everyone within the citadel. there is no camelot, not anymore, not without her people. merlin should’ve seen this coming as her one true ruler has been and will always be arthur. he waves a hand and puts out the fires and restores the buildings to their once gleaming glory then takes excalibur into the center and drives it into the stone. with the force and power behind it, merlin raises the earth around the kingdom and buries it away from further invasions.

he leaves the kingdom hidden beneath the earth and travels up to the surface to explore just how far the continent spreads. then theres new continents across the ocean and he explores those as well. he watches as the world expands and grows and learns and advances but humans go too far and begin to destroy the world and create weapons of mass destruction and threaten each other with war. merlin assumes arthur will come back considering the destruction of practically everything but he doesn’t. tensions rise and snap and in the blink of an eye, humanity is chased back to their caves. with the loss of technology and modern ideas, humans revert back to their roots and connect with the elements which means they reconnect with magic. it takes another few thousand years for these humans to achieve the level of civilization merlin grew up in his first few decades of life.

different tribes are settled across the land but, thats the thing, over the course of the last few millennia (lets pretend land moves super quick plsplsplsplspls) the separate continents have collided with one another and practically the entire mass could be considered albion. he’s not even sure where the original land resides now. sooo he’s not even sure where camelot resides now. he really should’ve set up some beacon so he could remember but its been thousands upon thousands of years. sue him for his memory being a little foggy. he wanders from tribe to tribe and learns from their new magic while acting as a physician which a lot of them consider him some sort of miracle healer considering his advanced medical knowledge. it’s a win-win tho, he learns new magic and they don’t die. everyone is happy.

then during one such visits to a tribe, he finds a man of twenty summers with a head of golden hair like a crown and sunkissed skin from working outside all day and bright blue eyes that look like the very sky was captured in his gaze. merlin stands for a while and watches him dig around in the dirt, sweat gleaming on his brow, and his muscles rippling as he works. merlin can feel the countless years falling from his shoulders, he feels lighter on his feet, and pure happiness bubbles in him. a grin wide enough to split his face pulls at his lips.

he can’t help himself from stumbling over toward his long lost best friend, his body awkward and gangly with excitement and when he calls out to arthur his voice seems younger than it has in millennia and he vaguely notices that his appearance of wizened old healer melted away to his twenty year old body. arthur looks up with a polite yet confused smile and greets him followed by a question and merlin is faced with the realization that arthur doesn’t know him, doesn’t remember him. merlin manages to keep a thin smile on his face as he reaches out with magic and finds an injury in his knee from years ago that must’ve been bothering him and excuses his use of arthur’s name as someone sending him to find him and help heal the injury.

anyways merlin and arthur become friends and set off on an adventure of gathering the knights of the round table from various tribes/villages and they eventually stumble upon gleaming white stone that merlin belatedly realizes camelot was built with. the knights all take turns tugging at the sword but it doesn’t budge, not until arthur reaches out and tugs as if expecting it to be y’know stuck in stone only it slides out like butter and he knocks the hilt on his forehead and knocks himself out it out. with the sword tugged from the earth, it rumbles and cracks and splits and a hidden kingdom arises from the dirt, gleaming white and shining in the sun. they stare in amazement and awe for a moment before they grow confused and distracted. then arthur turns to merlin and says his name in an all too familiar way and merlin starts sobbing bc arthur is finally back
