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:

• Ragabash: Auspice of the new moon, the Trickster. The Questioner of the Ways. Ragabash have a duty to question Garou society and, by so doing to show what needs to be changed and what doesn't.
• Theurge: Auspice of the crescent moon, the Seer and Shaman. The Searcher of the Ways. The Theurge serve as intercessors between their Garou brethren and the spirits.
• Philodox: Auspice of the half moon, the Mediator, Counsellor and Judge. The Keeper of the Ways. The Philodox are tasked with knowing the laws of the Garou by heart, thus discerning right and wrong as well as settling disagreements.
• Galliard: Auspice of the gibbous moon, the Bard. The Lover of the Ways. The Galliard remind the other Garou of their heritage and history with their passion for the ways of the garou.
• Ahroun: Auspice of the full moon, the Warrior. The Protector of the Ways. While all Garou are warriors, the Ahroun excel at the arts of war, even if they are often unstable. Their task is to enforce the ways with skill, tactics and, if necessary, with brute strength.

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.
