I'll show you the description. There's a bit more information in the descriptions of e.g. Chiefs, Warrior Smiths, Shamans and Iron Warriors. Every tribe is lead by a triumvirate of a chief, a smith and a shaman. The chiefs lead in matters of war, shamen in ways of the spirits, smiths in judicial matters. Iron Warriors are sons of the smiths who don't follow the path of their fathers, but war with mauls and heavy (for Early Age) armor.
