All Yerren have basic resistances to Physical, Pierce and Fire attacks. In turn, nearly all of their attacks are of these damage types, too. The Yerren are first met in the ruins of the Village of Guanzhong. However, Barmanu, a Neanderthal warlord encountered in the caves at the Tsongmo Peak, is also actually a Yerren. Yerren are later encountered in large numbers in the Jinghe Wetlands, close to the gate to Chang'an.
