Imhar Canyon, situated on Ossus, was the site of a Jedi temple as documented in the Qel-Droma Epics. This temple, led by Jedi Master Anstak, was uniquely positioned within an underwater tunnel system where Anstak instructed Padawans who were of amphibious descent. Following the destruction of Ossus by the Cron Supernova, there was speculation that Anstak and the Padawans he taught might have found refuge and survived within the deep, submerged caverns.
