Beast Wars of Onderon
a series of battles that spanned nearly 350 years prior to the first Old Republic contact with Onderon. The battles were foguth between the citizens of the city of Iziz and its outcasts, the Beast Masters. Iziz managed to survive because of its superior technology and its link to the Dark Side of the Force. The ancient Jedi Knights, under the direction of Arca Jeth and the command of Ulic Qel-Droma, interceded and brought the wars to an end.
