Warrior tribe
From Tardis Wiki, the free Doctor Who reference
A selection of North American Warrior Tribes, including the Kiowa, Cheyenne, and Paiute were used as an experimental form of Remote colony by Faction Paradox, an attempt to examine the innate tendency towards ritualism of the human psyche. What drew the Faction to these groups was their focus on self mutilation, as well as their usage of totem weapons taken from their enemies. (PROSE: The Book of the War)
