Odan-Urr, Jedi Master and founder of the Great Jedi Library of Ossus, was one of the order’s most famous and long-lived members. Although he participated in some of the most decisive battles of his time, Odan-Urr preferred the life of an academic, overseeing the library’s Chamber of Antiquities for centuries until he was slain by Exar Kun shortly before the cataclysm inflicted by the Cron Supernova.

Of his many accomplishments, perhaps the most influential of Odan-Urr’s works was his revised version of the Jedi Code, which he created in response to the struggles of his pupils to fully understand and embrace what it meant to be a Jedi. Odan-Urr’s revised wording of the code became the definitive version, taught and recited by Jedi ever since.
