The Authoritarianism of "Father's" Celestial Realm (NB Season 2)

OKAY, life got crazy for a while, but we're finally all caught up on Nightbringer's main story, and PHEW we've got some things to talk about. So let's dive right in, starting with one of our favorite topics:

God and the Celestial Realm actually kinda suck in the OM universe!!!

(spoilers up to NB lesson 38!)

Now, this been a consistent pattern for most of OM's story and lore, but we're going to be focusing here mostly on Lessons 37 and 38 in particular this time, because they had a lot to talk about in that regard.

In Lesson 37, we are introduced to the underworld, specifically Cocytus at the very bottom layer of it.

One interesting note, however, is that this region is territory of the Celestial Realm, despite it being geographically in the Devildom, and the Celestial Realm is the one that doles out punishments relating to it -- usually. We'll dive more into that whole conspiracy in another post, but it's certainly an interesting geopolitical fact of the Three Realms.

As for the underworld itself, the idea of multiple layers of hell is a common one which originates from Dante's Inferno, the first section of the Divine Comedy, and we see that Cocytus here is taken pretty directly from that as well. Just like Dante describes in the Divine Comedy, Simeon informs us that there are four regions that make up Cocytus, made up of four concentric circles of growing intensity according to their corresponding offenses. Specifically, each layer of Cocytus is related to a type of betrayal: of family, of homeland, of guests, and finally, as the very worst type of betrayal, of "him".

The design of that is immediately very telling about how the Celestial Realm views these offenses. Other offenses may land a person in the underworld in general, but these specific types of betrayal are the worst. And among those worsts, betraying God is the ultimate offense, absolutely beyond anything else one could ever do.

Now, these levels of Cocytus almost directly match Dante's Inferno take on them -- with one major, interesting distinction. In the Divine Comedy, Judecca is for "traitors to masters and benefactors." In OM, it is traitors to "him." Considering that the rest of the levels are a direct match, this suggests that, in OM, their father is the master who must never be betrayed.

And as Mammon notes, that's exactly what our beloved demon brothers did, with Lucifer in the lead.

That brings us to the present situation, with Lucifer chained and suffering at the very center of the bottom of the underworld. The worst of the worst offenders.

Simeon, Luke, and MC arrive to find Lucifer in a screaming rage, noting that same fact. Lucifer is in such pain and rage that he's creating dangerously massive gusts of wind, and as he worries about MC and then his brothers, it only gets worse. Suddenly, Raphael appears to read Lucifer his charges. And then, we get this conversation:

There's a lot going on there, but to go piece by piece, Luke is obviously distraught upon hearing the brothers' decreed fate. He wants to protest it and argue against it. Simeon stops him because Luke absolutely must not say another word -- as a reminder, arguing against Lilith's punishment was the catalyst for the whole rebellion that ensued, which is the entire reason Lucifer is being punished like this now!

Simeon, however, has recently been demoted. We know he was a seraph at the time of the rebellion; the official Nightbringer website specifies that he was demoted for "covering for" the brothers, though we don't know the specifics of what happened there. Simeon has always been a little daring on speaking truth to power, and considering he's already been demoted, it seems he's willing to take the potential consequence of speaking up again here. So he does, expressing his questions and concerns about the whole situation going on. And, finally, he calls out Raphael on also feeling the same as he and Luke both do.

It is perhaps the most telling moment we've gotten to date of how Raphael has felt about this whole civil war between the angels. In the past, he's been fairly consistently strict about the Celestial Realm's rules, which essentially boil down to always obeying their father, and Michael by extension. And he holds himself to basically the same standards, obediently doing whatever Michael tells him to even as he's disgruntled or frustrated by the myriad requests. But when it comes to seeing Lucifer punished this way, he can't accept it either. It's wrong, and he knows it.

But he can't question decisions that come from on high. Even doubting is considered wrong.

We've heard the same from Lucifer once before -- that he questioned one who was never to be questioned. That is what he has been punished for.

This is the reason Luke must not speak up. This is the reason Raphael is crying. And it's the reason for Lucifer's current punishment. Simeon, Lucifer, and Raphael all know it implicitly -- what comes from on high is absolute. Questioning is unacceptable. Doubts are unacceptable. And rebellion is unacceptable -- the absolute worst thing that someone can do.

Anyway, now throw all that out though, because apparently Lesson 38 wants to attempt to bring us to a completely different conclusion!

Let's be honest here -- OM is a bit jumpy on its writing sometimes, and sometimes makes wild left turns. But we ended Lesson 37 feeling pretty excited because it's revisiting a common theme we've had hinted at throughout both games about what kind of leader their father is and what kind of place the Celestial Realm really is under him. And what we've seen, generally, is this: it is a very strict place, unforgiving of those who step out of line, where their father's word is absolute, and even feeling doubt is a grave offense. We even know that Simeon's greatest fear is their father!

So imagine our shock and disappointment when Lesson 38 suddenly decides that, no, actually, this punishment and everything else is actually God's love for them. What?!

New theory: exactly one person on OM's writing team is actually super religious and keeps trying to make this game about dating demons into a message that God is good. These lessons were not written by the same person.

Lesson 38 starts with a rather chaotic scene -- Lucifer has broken free of his chains and is lashing out in rage and despair, not thinking straight. Diavolo makes his appearance and tries to subdue Lucifer, though the two end up going into an all-out brawl as Lucifer lashes out at Diavolo as well. MC eventually intervenes and the brothers show up to protect MC from both Lucifer's and Diavolo's attacks. Lucifer is taken aback seeing that his brothers are all okay and present in front of him, and as MC approaches him to further calm him down, the Ring of Light glows and Lucifer momentarily transforms into his angel form, inspiring awe from everyone around at the sight of the Morning Star once more.

Earlier, Lucifer was begging to be shown some kind of sign from his father, of what it was that he wanted from him. Simeon comments that this might be Father answering that call for a sign -- a sign of his love. Lucifer seems to accept this, though with some bewilderment. But we have Lucifer straight up tell MC later in the lesson that he "must have forgotten" that Father loved them all along! That all he ever did was give, and never ask for anything in return!

Except for blind, unwavering loyalty. Something that Lucifer has actually forgotten about in this moment.

For that matter, why does Simeon automatically assume it's this grand sign of their father's love?! He himself just stated his own doubts and called Raphael out on his.

It's a huge 180 that gave us some intense whiplash for sure. But this isn't the first time we've seen that more religious trauma view from Simeon; we've seen it before in OG season 4, where he has obviously been deeply affected by being demoted out of being an angel altogether but tries to reassure himself that their father does everything for a reason, "even this."

However, even aside from the very sudden turnaround, this explanation leaves a lot to be desired, because it doesn't actually answer anything!!!

We just got told that Raphael was crying from the cognitive dissonance of obeying orders to read the charges against Lucifer while feeling deep down in his heart of hearts that this is wrong. Luke has been stopped from saying anything that could be construed as going against their father! Even harboring doubts is wrong, but somehow we are supposed to suddenly believe that it's because their father loves them?

If that's God's love, it's sure sounding like God is an abusive helicopter parent, because that's not a healthy loving relationship.

Think about it -- this is a scene of punishment. Lucifer isn't just chilling down here for fun; he is actively in pain when we find him, and it only escalates his torment at the thought that his brothers are being punished similarly. And even as we are told that Little D. No. 1 couldn't take material form because their father "just loved them so much," is it really a healthy form of so-called love to hold on to a piece of Lucifer's soul without his knowledge, even after casting him out?! We wouldn't say that a parent who throws their own child out to be homeless while keeping their old room intact is a good, loving parent; why should we think this is any different?

Plus, this is the case for Lucifer -- but what about the other brothers? Though they all managed to get free, Cocytus itself seemed prepared to punish each of them for their various transgressions, and as Mammon points out, all of them were guilty of treason against their father. Yet, it's only Lucifer whose Little D. was never able to take form. It is Lucifer specifically who is targeted for this Cocytus punishment, and the others would likely have been left alone if not for the fact that they came to save him. Lucifer is the one who, for that one moment, regains his angel form.

And what does this mean, if this is God letting go of the last of his grip on Lucifer? That he still loved his favorite son but is casting him away for real now? We know Lucifer has said that God would never forgive him in particular, and though he's been accused of just being stubborn himself (and make no mistake, Lucifer certainly is also stubborn too), it does seem in line with everything else we've been shown about their father. Does this mean that their father no longer loves Lucifer, from this specific point onwards?

And, if their father loves them so much -- then why did they need to rebel for Lilith's sake? The implication here is truly bizarre: their father was going to obliterate Lilith entirely from all existence so that not even her soul would remain, but he also just loves Lucifer so much, but is also so authoritarian that Lucifer trying to talk it out with him was met with a complete shutdown so that Lucifer felt he had no other choice but to start the war. Of course, conveniently, this lesson also just chooses to completely disregard the whole Lilith thing, both her existence at all alongside the brothers before the war and her punishment, so apparently none of that matters!

It's completely out of line with the rest of everything we've ever really been told about the Celestial Realm, and frankly, we don't like or accept it. This so-called love that's suddenly used as the explanation in Lesson 38 isn't a true or healthy kind of love, and we don't want it.

So in conclusion: God is gaslighting us but he really does totally actually suck. We're just supposed to suddenly believe now, out of nowhere, that he doesn't. But he definitely, really does.

Anyway so, Lesson 37 is 10/10 and 38 is -10/10, would not read again. Merry Crisis!

I swear I adore Obey Me and it's characters, but I hate how little information the devs give us about the Devildom/other realms, like, I'd like to know what a standard demon ethic is, maybe a bit about the law too, what other magical items exist even if they aren't necessary for the plot, how strong could a demon/angel get, more about the different cultures of both angels and demons (more than sweets/food that is, there's gotta be more, c'mon), maybe a map about the Devildom, it'd be nice to know how far things are from each other and not have to guess.

I sometimes wish that Obey Me had an encyclopedia or something to know this little details about how the different worlds function, perhaps including it in-game as a new feature would be nice. This could also give the MC a deeper understanding of what they've gotten into, because I can't believe they even went to the past without knowing at least basic history (more than the Celestial war, it is known that demons and angels had beef waaaaay before that).

Major Nightbringer S1 spoilers

Not enough people talk about how Michael's whole "plan" in S1 was not only insane towards the brothers/the Devildom but also a straight-up act of defiance against God.

Like, it's implied at least twice, by both Simeon and Raphael, that what Michael did miiiiiight not have actually been Father's will.

^ the first scrutiny, from Simeon. Implying that what Michael said and what God actually wants are not the same.

Now, I'd brush this off as just a part of Simeon's "starting to doubt and fall away from his faith" character development arc, if Raphael didn't back this up with complete confidence later on. You know, Raphael, the one said to be "the only one who truly understands Michael"?

This is what he had to say:

"Just because he missed his former brothers."

"Just because he missed his former brothers."

LMFAO.

He didn't go down there on an order from Father. He didn't go down there to be Father's spokesperson. He went down there for his own purposes... while pretending to be a messenger of God.

He spent his entire time in the Devildom putting words in Father's mouth and intentionally misrepresenting his will. That is, like, the purest and most blatant form of heresy one can commit. Our "good boy" angel is literally a heretic.

The entire climax of S1 was basically Michael doing the equivalent of forging your parents' signature on a field trip permission slip. Fucking dying

Headcanon: Lucifer problem-babysitter Morningstar

________________________________

It's canon that baby-angels, before becoming an important component of Heaven-society, are taken care by one angel-guardian. An example that we all know is Simeon with Luke.

That means that the brothers (expect Satan) and Lilith had a guardian, back when they were little angels.

So I have this headcanon that Lucifer had to babysitter all the problematic angels that other didn't want/weren't able to handle.

-Mammon: He is canon. Michael asked Lucifer if he could try to speak to him, and somehow he end up with the first one.

-Leviathan: After all angel saw how he was able to handle Mamm, they thought "Why don't try to give him this anxiety-walking". And boom- (Spoiler 3 season) an Heavenly Admiral.

-Asmodeus: And so, when an "give me attention" come out, who everyone thought? Lucifer

-Beelzebub and Belphagor: Twins? Having to take care not 1, but 2 angels at the same time? He already got 3, why they have even try to take care of them: let's give this couple to the Morningstar.

-For Lilith (Nightbringer spoiler), a direct girl, without a filter when talking, and extremely competitive, not-want-to-lose... Lucifer adopted her without thinking twice.

That also explains their family-relationship.

For Lucifer, he either grows up by himself or maybe his guardian was Michael. Why him? I don't remember any part that say that they have the same age and that could perfectly explain why this angel is always interested in him and his family. Probably 1st dad want to know how his son and grandchildren are.

In the end? Lucifer is a tired mom.

Trouble's Brewing

Michael

My heart's pounding as I walk up the steps of the mausoleum and approach the glowing white orb floating inches above the marble pedestal. By the time I kneel in front of it, I feel like I'm going to throw up.

"Forgive me, Father, for I have failed you. I will accept whatever punishment you see fit."

"Worry not, my child." His voice echos inside my head. "I should have known they would not come willingly. Were you at least able to gather information while you were down there?"

"I was. There are members of the House of Lords that are less than pleased with the prince's decisions regarding them."

"How many?"

"Roughly 25%, including those in the upper part of the House."

"That is excellent news. We only need two of them to activate the Rembandy Accord." A chill runs up my spine. That accord hasn't been used in millennia, and never in a situation like this one.

But it would be foolish of me to question Father, so I try to block out those doubts before He can sense them.

"May I ask who our representatives will be?" I ask.

"You will be one of them. I still have to decide on the second. Is it true that none of the other Seraphim helped you?"

"It is. I had to ask Simeon for assistance." He sighs.

"I imagine his loyalty is still divided. Sometimes I wonder if I have been too generous with him." My stomach sinks.

"Then again, based on your reports, he has been doing what he is told lately, even if he has reservations about it," He adds. "That is more than I can say about them."

"I believe he is trying to set a good example for Luke. Placing a young, impressionable angel under his care seems to have ensured his cooperation."

"How wonderful. Continue keeping an eye on him and reporting on his activities." He pauses. "Is there anything else you would like to inform me about?" I take a deep breath, attempting to calm my nerves.

"They have an attendant," I respond once I feel calm enough to speak. "Their name is Zephyr. I do not trust them. They appear unassuming, and yet whenever we were in the same room, I was on edge. I wanted to put as much distance between us as possible, but their presence was either requested or required by the prince beforehand, so I had to remain where I was as to not cause a scene."

"Are you able to articulate what about this particular demon made you feel this way?"

"They are hiding something. They know a lot more than they are letting on. I am not sure about the breadth or depth of their knowledge, but what I can tell you is that they saw through my illusion the moment they set eyes on me."

"How do you know?"

"They seem to possess the power of telepathy. When I shook their hand, I could hear their voice in my mind."

"What did they say?"

"You're not Raphael." He hums, clearly curious.

"Perhaps they have met him before."

"I thought that was the case, but it is not. Simeon and Luke are the first angels Zephyr has ever met. Plus, none of the other demons saw through the illusion, not even the prince. Any suspicions they might have had were directed towards the brothers being allowed to return here."

"You always have been good at blending in the shadows," He remarks. "That brings me to your next assignment."

"I am ready, Father."

"Good. I want you to return to the Devildom. Make sure your presence there is unknown, even to your brothers and sisters. Document everything you can about Zephyr and report your findings straight to me. They may pose a threat to us, so we must be prepared to take action against them if necessary."

"What about the Accord?"

"For now, leave that to me. I will let you know when I am ready for you to play your part in its execution. Just focus on gathering as much information on Zephyr as you can. Do I make myself clear?"

"Yes, Father." He really is worried. He never refers to anyone by their name, let alone repeatedly. He even calls the most powerful demons and humans by their titles, whether it's "the prince's butler" or "the witty sorcerer".

So why the sudden change? What makes Zephyr stand out that much to Him?

I suppose I'll just have to find out for myself, won't I?

I feel like Luke was born AFTER the war only because god must’ve been like “ Oh myself, I just lost like hundreds of my children, better replace some of ‘em 🤷” and thus Luke was born with a few others because honestly who has the time anymore and who wants to risk ANOTHER war because a new batch of siblings were born?

[inhuman-obey-me]

Lets say Lucifer won the battle what would have happebed? A lot of other media suggests Lucifer becomes God..for a short while

Honestly, that's a tough question!

We'd have to start with what would winning the war even mean? From what we've learned about God, he certainly would not be the type to just surrender. He's been shown to rule with quite an iron-fist, and as Lucifer straight up says, was never meant to be questioned. Angels are taught that he is all-knowing and all-powerful, the highest being that there can possibly be -- something which even Lucifer himself, before meeting Diavolo, fully believed and accepted as simple fact.

(spoilers for Nightbringer Lesson 17 - Hard, below the cut)

We've also seen Simeon tremble in fear at the mere illusion of God. He is an authoritarian presence and is the one who creates the angels and gives them their powers -- and can just as easily take them away (e.g. Simeon). He and His will are not to be doubted.

We also don't think Lucifer was exactly trying to kill and/or replace God either -- from what we can tell, he really just wanted to get God to listen and change. There was obviously the whole Lilith situation, but even before then, Lucifer didn't understand why "Father" never proposed the idea of peace with the Devildom.

Over time, he had become frustrated by the Celestial Realm's ways, and Lilith's punishment was the breaking point. He couldn't just stand by and do nothing.

In a rather tragic sort of way, Lucifer probably knew deep down that there was slim chance of winning, but he took the risk anyway and clung onto that slim chance of getting his Father to concede, rather than giving up and letting these hypocrisies kill his sister.

But alright, let's imagine God did concede.

While the more "traditional" version of events does indeed paint Lucifer as aiming to "become" the new God, Lucifer's goals in OM were never about obtaining power, and he's just...not really the type to want it that way. He doesn't like having everyone's attention, he's not usually trying to push through his own ideas or plans -- hell, he doesn't even like people taking pictures of him. At heart, he's actually more of a bureaucrat who likes working in the inner day-to-day running and execution of governance.

But someone has to lead the realm, and if there is one thing Lucifer absolutely is, it is responsible. So, if he had won the war, maybe he would have taken the reigns for a little bit, just to ensure that the changes he wanted were handled properly. He would have stopped Lilith's punishment, obviously, and presumably changed the laws to at least get rid of obliteration as a punishment. We also know that he had been actively working with Diavolo on the goal of harmony between the realms, so progress on that from the Celestial Realm side would have sped up a lot.

Lucifer would definitely change the way the Celestial Realm is run -- maybe that means letting the Council of Seraphs be the real leaders, not God, not any singular person. A lot of work would have to be done to change the Celestial Realm's way of thinking, so he'd probably task his brothers (and whoever else fought in the war with them) with going out and educating the others. They'd all have to work together to figure out what the future of the Celestial Realm looks like.

In conclusion -- things would be a lot better. :) Happily ever after, the end!
