This takes inspiration from the 'Dark Nights: Metal' comic series. So, the stories that go here MUST follow the idea of the Dark Multiverse.

" Stop me if you've heard this one... worlds will live, worlds will die... but imagine if your every fear, each bad decision, gave birth to a malformed world of nightmare. A world that shouldn't exist. And desperate as it fights to survive in the light of the true multiverse far above... these worlds are doomed to rot apart, and die, because they are wrong at their core. Welcome to the Dark Multiverse. Home to stories that should never be... It's all one big cosmic joke, except no one on this side is laughing. ...well, almost no one..." - The Batman Who Laughs
