As brethren fought brethren, the treacherous Wan Xian glutted themselves on the dragon nests that the werecreatures had originally protected. When the Wan Xian were finally transformed into the dark creatures known as Kuei-jin, the Xiong Ren realized the betrayal and lashed out in savage fury against the civilization of mortals that worshipped their fallen protectors. Afterwards, the Hengeyokai, or Beast Courts, were founded in order to prevent another war amongst those Fera loyal to Gaia. Many Fera were exterminated during these days, among them the Okuma, the eastern branch of the Gurahl.
