Humans have been putting different, sentient species into captivity for years now, including some of their own, called Aberrants. Aberrants are humans that have abilities (called Traits) that your average Joe would not, and though rare, are seen as very dangerous. Grey Evans just so happened to possess a Trait and was thrown into a holding area called the Shelter, which holds many other odd and/or powerful creatures, such as fiends, celestials, Medleys, ghosts, and undead. The Shelter was a place Grey feared for most of his life, but is it really such a chaotic, scary place? Will he ever be able to leave?
