At the time of the Cron Supernova, the Great Jedi Library of Ossus was overseen by Ood Bnar, a Jedi Master specializing in knowledge of the Sith and their use of the dark side. Though his tenure as head librarian was short, Ood Bnar served loyally, defending the library’s artifacts from the Sith Lord Exar Kun in the final moments before the supernova razed the planet.

As a member of the tree-like Neti species, Ood Bnar could alter his physiology and shape, allowing him to transform from a humanoid into a towering tree in order to envelop and protect a cache of ancient lightsabers. He entered a form of deep hibernation as the Cron Supernova struck and has yet to rouse from this trance-like state. Master Gnost-Dural and many other Jedi have meditated at his roots, hoping to communicate and learn from the ancient Jedi, but thus far, Ood Bnar has offered no response.
