Olis was a male Human prisoner of the city Iziz on Onderon around 4000 BBY. Olis was to be cast out to the wild outside Iziz as punishment. Before Queen Amanoa finalized the punishment, Olis foretold that Iziz would fall due to its suffering from the darkness for three centuries. He might be a Force-sensitive, as he claimed to be able to sense the dark side in the Queen.
