The dark arts are known to warp those who use them, and none exemplify this more than hags. Deep in the Wraithwood, they lure innocent victims to their doom, using their blood in potions and their bones in stew. Over time, such dark perversions grant hags power but twist them into hunched, distorted, wart-covered versions of their former selves.
Becoming a Hag
Hags are dark arts practitioners who are forced to live deep in the wilderness because their horrific practices (e.g., cannibalism, child abduction) make them feared and hunted by civilized races. Their transformation is typically a gradual thing, though it's said that covens of hags can concoct a special brew that allows its drinker to speed up the process.
Costuming for Hag Characters
Hag characters must use prosthetics to have a hunch on their back, a crooked nose, and visible warts.
