Olduvai Gorge
From Starsonata Wiki
In these misty depths, you will encounter a fearsome knight, Knight Ghorah Khar, and his stalwart companions who guard the gate to their leige lord, Prince Sutaghi Kilrathi in Olduvai Depth. The Knight himself flys a heavily modified Zebra, boasting twice the armament of his companions.
The gate to this terrible place is located in Ngorongoro and contains the gate to Olduvai Depth, the home of the dreaded Prince.
