Most packs contain one tribe with several auspices, but multi tribe packs are becoming more normal. Pack leaders are chosen in many different ways, from single combat to dice. The least common method is voting. A Sept is a group of packs banding together around a cairn. Cairns are the sacred places where Gaia's natural energy fuels the Garou.
Septs are the social-political organizations.
Only the sept leader has a chance of out ranking the warder. To disobey the warder doing his duty is to be forever scorned. Warders are usually Ahrouns or sometimes Galliards. A Theurge usually is drafted for this, but an occasional Philodox will do it. When tempers flair and duels are fought, the Master of the Challenge makes sure the fight is clean and honorable.
