Ooroo Canyon, featured in the Qel-Droma Epics, was a site found on the planet of Ossus. The Epics state that this canyon was named after Ooroo, the Jedi Master who mentored the Jedi Odan-Urr. It is said that Odan-Urr built the Great Jedi Library within the canyon following Ooroo's death in the Great Hyperspace War, fulfilling a pledge to his former master.
