A/N: This story will be a crossover of Overlord – the anime, Dingirverse – the book universe, and Diablo 2 – the game. It will mostly be Overlord, but some elements from the other two. This first chapter is a status page and history for the OC Supreme Being 'Obsidian'. For certain races and such, I made things up based on game and book crossover aspects. I will start the story in earnest once I catch on my other stories. I own the rights to the Dingirverse, but not the other two, I'd be rich if I was. But as we're looking at up to two years for season 4, I think I've got time to catch up.

The 41st player to join Ainz Ooal Gown, and after the others left, Obsidian would visit Momonga at least once a week, even if for an hour or two, as he worked insane hours as a manga assistant. Something that Momonga greatly appreciated, knowing how hard his friend worked.

Unlike most players, Obsidian focused on races and classes that allowed him to boost and protect himself, while restraining and weakening his opponents rather than the pushing the high tier magic attack route. He has over a hundred passive spells and skills constantly in use, and whether alone or in a team, he caused great chaos on the battlefield, with the GM eventually giving him the job 'ruler of chaos' which complimented his other dark races and jobs.

Obsidian has the appearance of a black haired human with a small moustache and soul-patch, and has concealable black angel wings and a black halo, the whites of his eyes are also black, and his eye colour alternating between gold and silver.

Obsidian has three transformations, his base form being a two winged fallen, the first transformation being a six winged fallen, however the next two are where it gets interesting. Chaos Beast was a reward that came to clearing the event 'Rise of Chaos.' The event involved defeating a hundred lesser chaos beasts, level 50, but they were granted near complete magic immunity for the event, but it was easier for Obsidian and his many buff/debuff skills. You then had to defeat the Chaos Beast itself, a level 95 giant of a monster, which looked a giant black demonic toad with wolf-like teeth, and armoured tentacles coming from its lower back.

Obsidian bested it on his first attempt; teaming up with Nine's Own Goal. They had gotten a god artefact orb and a unique avatar; Obsidian was elected the MVP and gained the new form. However it didn't work due to the hasty development and it had bugged, it was never fixed despite many complaints. Obsidian joined Nazarick during this time. But the form works in the new world.

His final form is Arch-cursed, the lore being an angel who becomes so powerful and evil that they become a new kind of evil being. It's the Dingir Legion form, see cover image, which allows him to use two super tier spells 'Pestilence' and 'Salvation.' Ainz Ooal Gown helped him achieve this when they raided a bonus sub-lair inside Nazarick, which activates as revenge to ones who conquered it, and he was lucky enough to get the kill blow.

Obsidian is one of the strongest guild members and one of the top 20 players in the game during when it was most popular, despite being a more support geared character. Ainz has better odds of winning against him though, due to his superior equipment, cash shop items, and spell diversity. But he has occasionally beaten the guild master in PVP.

Obsidian has no NPC's, using chaos summons when he needs something taken care of or killed. He uses the bonus room as his private domain where he stores his many imbued items/equipment/weapons he collects and creates, some of which he sold for real money as he was very creative with what he made.

The story begins on the last day, when after an 18 hour shift, at the end of a death march, Obsidian learns of the game's deletion, and logs in roughly an hour before. Obsidian hadn't logged in for several months due to the insane work hours, missed the deletion notice and now realised he wouldn't get to enjoy his favourite game after being kept from it so much lately.

Obsidian meets Momonga at the throne room, and the two pass the time, before their happiness and efforts are erased…However readers as you know, that is not the case, welcome to the new world.

How will Momonga/Ainz act with an ally from the start, someone more level headed and kind, his mind not being affected too much in terms of cruelty and evil after losing his humanity? Someone that could probably make Ainz a custom item so he can actually get laid.

For now this a concept chapter, as I have loads of other fanfiction, and professional novels to finish right now. But I'll try to get the first chapter out before Christmas.
