Garou society is divided into five auspices, or spiritual life-paths that a Garou is born with. They are tied to the phases of the Moon and considered gifts from Gaia's sister Luna. These auspices determine (to some extent) a Garou's Rage, or violent predatory instinct. The auspice system is one of the pillars of Garou society as it helps to describe social caste, predisposition's, and calling. The auspices are:
These auspice names, the ones most widely used, were originally devised by the Fianna; and several of the other tribes (particularly the Get of Fenris and Wendigo, who have grievances with the Fianna) use their own nomenclature when referring to auspice. Some garou also use the associated moon phase instead of the auspice' name, as in "I'm Evan-Heals-The-Past, a half moon."
As a Garou performs deeds fitting with their auspice, they rise in rank in Garou society. While Garou can renounce their auspice and select another more suited to their true calling, this is a grave action, done only in cases where a Garou's auspice truly does not fit their destiny. Such a Garou turns his back on his former life completely, renouncing not only his auspice, but his renown and even his spirit-granted gifts as well.
