Rite of the Totem (Level 3): You have a similar interest. A singular common goal. So what if there's only three of you? You're a pack now, or you will be once this rite is complete. Spirit quest, typically led by the ritesmaster, or quite possibly even separate quests for each member of the pack who wishes to petition, as the totem has to decide if the Garou petitioning are worthy enough to become his fosterlings.
