Lycanthrope

Lycanthropes are a fallen race of Mystical Creatures, cursed forever to be trapped in human-form. They can transform into their natural form under certain conditions, usually when large amounds of refined magical energy is available.

They are mostly vicious, hateful creatures and considered trully evil.

Lycanthropes are extremly rare, with only a handful in existence. You would be lucky to see just one in a single human lifetime.
