Page "Werewolf: The Apocalypse" Paragraph 56

Auspices are not the end-all-be-all role of each garou.

In fact each garou is expected to serve small functions of each auspice.

Ahrouns are usually the leader, and therefore must be able to sometimes perform mediaton.

Other garou besides theurges are expected to deal with spirits, even though it is not their primary function.

This is why many tribes and other auspices have gifts specifically to deal with spirits ( example, call to duty, a philodox gift, and spirit speech, and Uktena gift ).

All garou are expected to fight for Gaia, not just the Ahrouns.

Some tribes, the Get of Fenris in particular, expect all of their members to be adept at fighting.
