Warping is a condition that accrues upon people, things, and places. It is always assciated with one of the four realms of power. It is usually accrued from prolonged exposure to a strong aura of one of the four realms of power or being the subject of a powerful spell or spell like effect. It can, but does not always accrue from botching the casting or invoking of any spell or spell like effect.
Warping is comparable in some ways to aging and decrepitude. Once obtained, it cannot be removed, at least not by Hermetic magic. As far as any magi know, it becomes a part of the subjects essential nature.
