A Character's Tribes are the subgroups they belong to. Tribes are ethnic groupings drawn along lines of Provenance, Kind, and Banner, as well as many other circumstances. They are a distinct subset of experience and opinion within a higher average. A Character belongs to many Tribes, and it is only by taking a step back and reviewing the Character as a whole that we can see their complete Ethnicity. Within the Core RPG, your Tribe is a part of your Backstory which flavors your Character's experience with their Provenance, Kind, and Banner, and which modifies your starting Abilities or Mantra.
