Ossus Keeper robes were worn by the Jedi who served as Keepers of the Hall of Knowledge in the Great Jedi Library on Ossus before it's destruction during the Great Sith War in 3996 BBY. These robes significantly increased the mental attributes of the Keepers and aided them in maintaining the protected archives in addition to guiding those who wished for interactive solutions to their problems.
Meetra Surik was rumored to have received a set of these robes as a gift from Queen Talia of Onderon for her help during the Onderon Civil War in 3951 BBY.
