Shapeshifting

Every Uratha may change at will into five distinct forms, each with its own benefits and drawbacks. The forms, named in the First Tongue, are:

Hishu - human form. An Uratha appears to be a normal, if very fit and healthy, human. An unconscious or dead werewolf returns to this form.
Dalu - near-human form. The Uratha is slightly bigger, hairier and stronger.
Gauru - wolf-man or war form. Half-human, half-wolf, Gauru form Uratha are generally 8 to 9 feet tall and much heavier and stronger than any human. In this form a werewolf's blood-lust rises to the surface and is much harder to control. Uratha can only channel the power of the Gauru form for a limited time, and generally only take this form to kill.
Urshul - near-wolf form. An Uratha in this form is a huge wolf 3 to 5 feet high at the shoulder.
Urhan - wolf form. The Uratha is indistinguishable from a normal wolf, though different Uratha resemble different breeds or species of wolf.
