Werecreatures are humanoids doomed to transform into animals and animal-humanoid hybrids under the light of the full moon.

Their ability to lurk unseen in the wilds as well as among people, combined with the contagiousness of their condition, makes werecreatures a perennial cause of panicked suspicion.
