Sometimes Gnolls turn against each other, perhaps to determine who rules a war band or because of extreme starvation. Even under ordinary circumstances, Gnolls that are deprived of victims for too long can't control their hunger and violent urges. Eventually, they fight among themselves. The survivors devour the flesh of their slain comrades but preserve the bones. Then, by invoking rituals to Yeenoghu, they bring the remains back to a semblance of life in the form of a Gnoll Witherling. Witherlings act much as Gnolls do in life, traveling with their comrades and trying to kill anything in their path. They don't eat and aren't motivated by hunger, leaving more flesh for the rest of the war band. Gnoll Witherlings are incapable of wielding any weapon more sophisticated than a simple club.
