Demonskin adepts are sorcerers who, for their spells and other abilities, rip away the power of the Abyss, stealing it from the skins of the demons to whom it belongs. This gives them access to powerful abilities but comes at a cost, for such power is indelibly tainted with the evil of the plane from which it comes, corrupting the heart of those who wield it. More to the point, the demons from whom the power is stolen rarely take kindly to the sorcerer's possession of it.
