Lycanthropy

Lycanthropy is a curse that can transform humanoids into beasts. A humanoid afflicted with this curse is called a lycanthrope.

Appearance
In their humanoid and animal forms, lycanthropes appear no different from normal. In their hybrid form they have their original shape with head and other features of the animal shape they are cursed with. Known types of lycanthrope include werewolves, werebears, weretigers, wereboars, and wererats.

History
The Claret Order of the Lycan has their hidden base in the Cyrengreen Forest, where they train outcasts to manage and use their lycanthropy.

The adventure The Unlucky Few in the Explorer's Guide to Wildemount involves a group of soldiers who have deserted to the Cyrios Mountains after becoming afflicted with lycanthropy.
