Evelyn is a werewolf in exile from her tribe after being seduced by shapeshifting demon Quijo and conceiving Muriat. Unaccepted by society for the violent tendencies of her species, she raised her child in the wilderness, instructing him in the ways of survival and hunting. She becomes substantially larger and muscular as the full moon approaches its zenith, with a corresponding increase in libido. Without a replacement partner, this would drive her to vent her lust on her son once he came of age and accidentally conceive a daughter, Gwendolyn, with him.
