I Have Some Ideas For Mephistopheles In This AU, But I Don’t Know Enough About Him Just Yet To Make

Armageddon: What Is This AU?

The Armageddon AU is an apocalyptic alternate timeline of Obey Me in which the exchange program was never created. This page is dedicated to all the juicy details of this AU that people (mostly me) cook up in our free time. Any and all contributions, whether it be headcanons, further lore development, speculation, art, or fanfiction, are wholeheartedly welcomed.

Be aware that this AU, by nature, is extremely dark and contains disturbing subject matter that may not be suitable to everyone. No punches are pulled here; this is an apocalypse.

~~~

To keep away from one intimidating essay, the main timeline is split up over a series of Lore Posts:

Lore I - The Beginnings of Destruction

Lore II - A Disrupted Balance

Lore III - A Scorched Celestial Realm

Lore IV - Hell Frozen Over

Lore V - Power-Sick

Lore VI - The Move to the Human World

~~~

There are also Character Files, which detail the roles of specific Obey Me characters in this AU:

Character File: Simeon

Character File: Luke

Character File: Satan

Character File: Michael

Character File: Raphael

Character File: Diavolo

Regarding MC

Character File: Diavolo

Unlike the brothers, Diavolo was never sent to war. As his father is extremely protective of him, Diavolo was forbidden from going to war. He was essentially locked in the Demon Lord’s Castle. 

While Diavolo’s father viewed the eradication of the angels as the best way to protect his son, it only made Diavolo grow ill from power-sickness. Though he hid his ailment from Lucifer and the brothers to avoid worrying them, his magic was eating him from the inside out. 

This timeline’s Diavolo still strongly believes in creating a respect between the realms, but unfortunately he is completely eclipsed by his father, the sitting ruler. With the overbearing presence of his father, Diavolo’s lack of political power compared to his canon self, and his ailment weakening him, Diavolo is unable to be anywhere near as assertive about his dreams as he was in canon. He tends to be more meek, shy, and humble about his beliefs, only sharing them with those he truly trusts and only on rare occasion.

However, as the state of the Devildom grew worse and worse, and his own condition grew more and more unstable, Diavolo realized he couldn’t ignore his father’s doings forever. He was tired of hurting every second of every day, he was tired of being cooped up in the castle like a prisoner and seeing only impenetrable blackness. He was tired of wondering if his subjects were okay, of wondering whether the brothers were okay.

He began to stand up to his father, protesting his behavior and pleading with him to consider deescalating. The Demon King always refused and sent him to his room.

One day, during one of their many heated arguments over the future of the three realms, Diavolo snapped. Blinded by his immense pain and angered at the state of their people, Diavolo did the unthinkable: he attacked the Demon King. All it took was one returned blow from his father for Diavolo to realize what he had done. In shock and realizing there was no way he could defeat his father, Diavolo ceased his attack. Before he could be punished for his act of rebellion, Diavolo fled through the castle doors, out into the darkness. Diavolo never returned to the castle after that. He was completely missing. Lucifer doesn’t even know Diavolo had even gone missing, as Lucifer had been off in the human world fighting the war when the fight broke out. Left alone and cold in the darkness, Diavolo refused to give up. Having given up everything, his only option left was to pursue his dream full-force. Diavolo started by helping his citizens. By this point, most demons had fled the Devildom, but of course there were some left behind who didn’t have the means to leave. Using his magic, Diavolo was able to teleport them to the Human World.

Eventually, Diavolo learned of the situation in the Celestial Realm. Unlike the demons, the angels didn’t have a choice to immigrate to the human world, whether they had the means or not. Father had strictly forbidden any angels from leaving the Celestial Realm unless they were doing so as soldiers to join the war, as an attempt to incentivize his angels to fight for him to escape their burning wasteland. Diavolo began sneaking into the Celestial Realm and smuggling angels down to the Human World.

Before long, Diavolo had quite the force of demons and angels alike behind him, building their own makeshift shelter in the Human World. It hasn’t been found out or invaded... yet.

So I've been reading some of @obeymearmageddonau 's Armageddon Au and decided to write a drabble for it

But first let's make some Characters for it

-There will be several OCs present in this

Arc(Archie)- He can be considered the 'MC' of his area.

He is one a several newly discovered hybrids (Human, Angel, Demon in that order of what genes are more dominant)

Like most hybrids in this and any future drabbles he has health problems originating from the conflicting DNA

Unlike the MC in the game the connection to the three realms doesn't have any effect on any of the realms but is instead destroying him from the inside out

He has access to a pair of wings and horns with a tail

These are considered his angel and human forms

He is the vice leader of a survivor group

Arch(Archelle)-Can also be considered the MC

She is Arc's older sister and the second hybrid known to their survivor group

Unlike her brother the Demon genes have fully suppressed her angel genes leaving her healthier in most aspects but with the drawback of having violent seizures and internal bleeding when coming into prolonged contact with angels

She has horns, wings, a tail, and darkened skin along her forearms similar to elbow length gloves

She is the leader of their survivor group

Angel-A side character of this story

The youngest sister and adopted cousin of Arc and Arch

While she is high school aged for most of this she is physically a child due to her demonic genes suppressing her human genes

Even though her demon side is dominant she has an incredibly weak angel (but still stronger that human) form

For her safety her other forms were sealed away the second her siblings found a way

This has a negative impact on her health but is still safer than Arc's situation

I am trying very hard to cut this. Sorry for the length

Solomon character file!!!! It will be very intresting and annoying at the same time for him in the au!

Hi, thanks for the feedback!! 

Though, unfortunately I’m not too comfortable with my interp of Solomon. I don’t know him well enough to try my hand at a full-on character file for him yet.

Considering he’s the only human character and this AU demands human involvement too, I will have to get around to him eventually (even if he isn’t quite HUMAN human). But now is not the time.

If you want some information on Solomon though, I did make a post a little while back vaguely explaining some things with him. He’s probably extremely confused by the whole situation, and doesn’t exactly have a good source of intel.

We see it mentioned in Season 3 that Solomon does business with Michael and has been doing so since long before the exchange program (which is where this AU diverges from canon), so Michael would probably be the first person Solomon asks about the whole situation. But due to some... circumstances with Michael, which will be delved into in Michael’s character file, there’s no way Michael is actually answering his phone for Solomon, much less meeting with him. Diavolo isn’t exactly available either (again, this will be delved into at a later date), Asmodeus isn’t exactly in a situation to be texting his boyfriend either, and Father and the Demon King are just plain uncooperative. So Solomon is meeting a lot of dead ends trying to figure out what’s happening. He’s definitely picking up on the magical disturbances, but no one’s telling him what exactly is going on. Which, everyone’s silence is arguably even more concerning.

I have to say, this might just be part of the “me not knowing Solomon well enough” thing, but I think Solomon would be less interested/annoyed and more genuinely concerned. I know he’s not the type to really get all sentimental over others, especially prior to meeting MC and Simeon, but the Armageddon is something that threatens the very existence of the three worlds. Solomon can’t exactly continue his magical studies and whatever else he does if all three worlds are completely annihilated. He can’t continue making pacts if there are no demons left to make pacts with. And I doubt he, as an immortal, wants to be completely alone in the universe after Father and the Demon King have destroyed everything in their wake. I think this situation is dire enough to bring out some real concern in Solomon. He’d probably have a desire to get to the bottom of it not just because he’s interested or because it’s simply an annoyance, but because life as he knows it depends on it.

After all, the closest thing we see to the Armageddon in canon is the situation with The Ring. Solomon definitely seemed pretty concerned over that whole situation. And the Armageddon is around that same degree of destruction and certain doom, if not far worse.

If Solomon does have a role in this AU, I imagine his role would be very similar to his role in Season 2 in canon- tirelessly researching to try to figure out what the hell is going on and fix it. Though, here he’s probably hitting a lot more dead ends due to having no one to help him.

Character File: Michael

Despite having not made an official appearance in canon yet, Michael has quite the role in this AU. I dare say his story in this AU is one of the most disturbing and tragic.

Michael suffers from power sickness, but his struggles don’t end there.

Michael is the most powerful Archangel and leader of the Celestial Realm’s legions, making him Father’s most powerful weapon of war. However, as we have seen thus far, the Celestial Realm isn’t satisfied with the power it has and is seeking more. As such, Michael wasn’t enough. He needed to be improved. Upgraded.

In his attempts to turn Michael into the perfect supersoldier, Father created an abomination. Michael’s form was warped into what could be compared to the most terrifying of the biblical angels. Two golden rings of eyes circled around his head, replacing the now nonexistent eyes on his completely smoothed-over face. More eyes peered out from between the feathers of his four wings, wings that were now permanently set ablaze. Smaller golden rings of eyes encircled his hands and ankles like shackles, and he has four arms instead of two. There are also disembodied eyes floating all around him, which he can move at will, using them almost like camera drones. Despite his mouth being smoothed over with skin like the rest of his face, Michael can still somehow speak, in an echoey and ethereal voice that brings chills to those who listen, a feeling that they are hearing something they shouldn’t. But no, Michael can’t eat, which as you could imagine is absolutely devastating to someone like him.

Despite his shocking appearance, Michael’s mind has remained unaltered. He is still the same person, the person who doesn’t want to fight Lucifer and his brothers. He is ashamed of what has become of him, and isolates himself from the other angels whenever he can. He is only really seen when he’s fighting in battle, and even then it’s hard to get a good look at him. He flies high in the air, keeping a distance from his fellow angels who cannot fly high anymore due to their scorched wings. He never speaks to his fellow angels anymore, having Raphael give orders in his stead as Michael himself focuses solely on fighting the opponent. When not in battle, he hides himself away in a dug-out cave underneath the camp. As the only person granted access to Michael’s hideaway, Raphael is the only soul that has heard him speak in a long time.

Due to being able to see (really well, given all the eyes he has) and the unimaginable level of power he has been imbued with, Michael is a very important soldier in the war and does fight on the front line. However, he only does so out of necessity, because he needs to protect his fellow angels and because he’s afraid of what Father will do if he doesn’t follow his orders. Michael dreads the day he encounters Lucifer in battle, and has grown to doubt Father after all he has done to him.

I love how you easily come up with such complex scenarios....it's amazing 😁

I try to write something but sometimes it doesn't make sense so I give 8

Thank you!

I think the fact that I’m an original fantasy writer in my spare time really helped. I’ve had a lot of practice with worldbuilding and such. For this specific project, I also took a lot of inspiration from an existing fanwork from another fandom, the Infinite Eclipse series by Jyc Row. Specifically this song from the series.

My tip is to start off with the big picture, and figure out the details later on. I didn’t start this AU knowing every little thing already; I figured things out as I went. I thought, “what is a logical consequence of X?” and went from there, and that’s how I got around 90% of my information here. It’s like a skill tree; you start with 1 point, the basic general premise, and as you explore, different pathways start to open up. After a while, things start to fill themselves in and you’re just hitching a ride.

Planning this way also makes it easier to sort out the kinks in the plot and prevent plotholes; you have your universe’s rules set up from the get-go, and everything else is a result of them. It’s hard to break a rule when it’s your main guideline, and things tend to be a lot more consistent when they’re united under a set of guiding ideas.

Ok but I’m even more interested in their parents. An angel and a demon getting together to create a family, in the middle of the centuries of building political turmoil from Lore I... 👀

Also, when I was first reading this, I was thinking “oooh, they can join the Royal Alliance!” But then I saw that Archelle has seizures when around angels... yikes! That’s a pretty big barrier to work around!

So I've been reading some of @obeymearmageddonau 's Armageddon Au and decided to write a drabble for it

But first let's make some Characters for it

I am trying very hard to cut this. Sorry for the length

I’ve added links in each of the lore posts to the previous and next posts in the lore series, to make the lore easier to navigate. I’m also working on a special Lore VIII and Lore IX- though those won’t be leaving my drafts for a loooooong while, as they’re essentially an epilogue to this AU.

(Additional content taking place at any point in the lore will still be created and accepted after the epilogue, this AU project is never going to officially “end”. I just want to make sure all the major stuff is out there for context before releasing all the lore, and I want to give you guys some time to digest the current lore before continuing.)

Character File: Thirteen

Thirteen, as a reaper, had much more distance from the events than the other characters did. Though she did reside in the Devildom, her deep cave did shelter her from the effects that ravaged the rest of the realm. However, Thirteen had to get involved when the Armageddon interfered with her job. She took notice that her candles were burning out at an alarming rate, across all three races in all three realms. She was absolutely dumbfounded- she was an experienced reaper, she couldn’t have messed something up this badly; what was going on?

Given her hermit lifestyle, there were few people she could go to about the situation. Her older sister Candy was out of the question. As the situation grew more and more troubling, Thirteen eventually had no choice but to go to Solomon. She confronted him angrily, wanting to believe he’d just pulled some prank as part of their rivalry, only to find Solomon disheveled and disturbed.

After exchanging their knowledge of the situation, the two of them formed a begrudging alliance. Thirteen still very much held her grudge on Solomon, and she had no real emotional attachment to the wellbeing of the realms, but she understood that as a reaper she could not allow the situation to continue. Life and death was her domain, and it was her job to keep them in balance. A reaper could not be a reaper in a world with nothing left to die. As such, she fought fervently to end the war, Solomon at her side.

Within their duo, Thirteen was much more of the front-line fighter. As Solomon researched and attempted to form political allegiances, Thirteen focused on battle. She fought against the armies of Father and the Demon King, as well as rogue human looters. Due to her more rough-and-tumble approach, she needed clothing much more suited to battle. Her exposed midriff was a strong disadvantage in battle; even a reaper wasn’t immune to physical attack. Her crop top was replaced with a full-length plated breastplate made of unknown material that was off-white in color, looking like bone. In the middle of the chest was a black skull shape. Thirteen also donned a dark mauve-purple cloak, made of thick fabric to defend from attacks. The inside of the cloak was lined with rows of pockets for storing her various traps. Though she very much still relied on her traps, she also took up a melee weapon, a large black scythe. Later in the war, an incident would happen that left her missing her left eye. After this, she also wore a black eyepatch.

YOUR AU IS JUST- *CHEF'S KISS* ITS SO GOOD I'M INVESTED IAGRBASRGOSARG

I’m so glad you’re enjoying it! Thank you so much for your support! :)
