The Ocata River and its tributaries flow through the southeastern section of the Mwangi Jungle in the Mwangi Expanse. It rises in the mountains to the east of the Bandu Hills and flows into Lake Ocota.
The source of the river is overlooked by a mountain which has had its peak removed, presumably by magical means. Lying on this flat surface is a massive fallen statue of a man with Azlanti features. The statue is carved from a rare black granite found otherwise only in certain remote islands of the Arcadian Ocean. Carved into the statue is the inscription "I point the way to Zurakai, never there to return." According to legend the statue it is the key to the location of a lost city called Zurakai.
