Years ago, a worldwide prison breakout caused the “Super War” between Superheroes and Supervillains, and most of the heroes were wiped out, allowing Supervillains to take over the world. Surviving Superheroes are few: Idyll is a servant for villains, and Halcyon has gone completely insane.

The world is split into many factions between the villains, and villains will fight for territory. Some villains with the largest factions are Dust Devil, Replicating-Man, Downburst, Blackout, and Queen Bee.
