Lycanthropy

Lycanthropes are any humanoids who have been infected with lycanthropy, a disease that can be transmitted either hereditarily or as a result of the infectious bite of someone already afflicted. Lycanthropes have, though are not always in control of, the ability to transform into various types of animals, or humanoid-animal hybrid form. Most lycanthropes have some empathy with animals with which they share their forms.

Werewolf
Werewolves in humanoid form have no real distinguishing markings. In wolf form, they fight as wolves in nearly all aspects. A werewolf in hybrid form usually dispenses with weapons to use its own teeth and claws, but it is capable of using one should it desire. They are not to be confused with wolfweres, who are wolves that transform into a similar humanoid-wolf hybrid form.
