Demon AU masterpost

A little more info on the demons in my 13 Cards demon AU! This AU is still very much a WIP, and plenty of details can change, especially when I get around to designing the various suits’ characters.


Demons are humanoid creatures whose biology and sociology leans towards a mix of cats, dogs, wolves, horses, pigs, and humans. Typically, they can come in all colours, sport horns and a tail, and possess nonhuman traits such as sharp teeth and claws, long, pointed ears, hooves, spikes, fins, fur, and scales.

They call the demon world their home: a large natural plane with limited resources and varying biomes, with an outer boundary that keeps them from leaving. At the centre of the demon world, there sits a giant demon named Joker, who will eat anything that approaches him. Outside of the centre, the demons are free to claim territory however they see fit.

Demons come in thirteen different ethnicities, which are culturally and sociologically divided into four suits. Vertically, there exist queen imps, king imps, and jack imps. Each of these belong to one of the suits: clubs, spades, hearts, and diamonds. Together, these two traits determine the traits that the imp will eventually possess.

The suits generally keep to themselves, only accepting members of their own suit. In the current rotation of queens, the clubs and the diamonds are open to cross-suit adoption, whereas the hearts reject other suits and the spades actively hunt anything that isn't a spade.
