In Jak II, an oracle was situated in a hut at the Water Slums which served to guide Jak in gaining control of his dark powers throughout the game. As Jak collected skull gems, the oracle would require a certain amount before giving him new powers. The small hut is located near in proximity to the pumping station's airlock.
The interior of the hut is lined with Precursor text scrolls reading "The noble will be assured of a place in history, this being granted a form of life to be forever venerated by their ancestors as one who lived a life of goo." Lit candles surround the oracle, creating an ambient atmosphere around the Precursor metal-crafted artifact.
