Auspice
A werewolf's auspice is a general template of attitude and behavior. Garou believe that the phase of the moon under which a werewolf is borne influences the Garou that he becomes. In this way, Luna teaches her sister's children their roles in life. Luna recognizes no Garou can be all things at all times; each auspice is one fragment of a grand design.
Your auspice also describes your place in Garou society. When you enter your tribe, you are assigned to a teacher sharing your moon-sign, who then instructs you in the ways of the moon. For simplicity, many teachers compare a Garou's auspice to an astrological sign, but the true significance of auspice goes much deeper than this. The moon-sign is seen as advice from Luna and as intregal part of each werewolf's being.
Auspice may be renounced and another path chosen, but this is frowned upon as a grave insult to Luna. A renunciate must undergo a Rite of Renunciation, a painful stripping away of the Garou's old identity. The renunciation starts again at Rank 1, keeping all former Rage but losing a fair amount of esteem in the Tales of such renunciates tend to circulate among the tribes; those who refuse Luna's guidance are not often trusted.
