Chamber of Antiquities The Chamber of Antiquities was a series of rooms and vaults deep below the main building of the Great Jedi Library on Ossus . It was here that Jedi Master Odan - Urr studied ancient artifacts under his care . Overview . Part of the sublevels of the Great Library complex on Ossus , the Chamber of Antiquities referred to the labyrinth of vaults and rooms that made up the second sublevel . Accessed by two lifts from the first sublevel , the level was offlimits to most visitors , as it contained the most dangerous items within the collection . Overseen by the Keeper of Antiquities , this being alone could grant a curious Jedi access to the collection . Among the treasures held within the vaults were dark side lore , including Sith holocron , the earliest known documents relating to the Jedi Order , and other sacred tomes . Several heritage tapestries detailing a pictorial history of the First and Second Great Schism s were kept on the walls , along with hard copies of ancient star - chart s . During the Massacre at Ossus , Dark Lord of the Sith Exar Kun violated the Chamber of Antiquities and assaulted and murdered Odan - Urr before stealing the Dark Holocron from him and leaving his corpse to rot . When the Cron Supernova rendered Ossus inhospitable soon after , the Chamber and the rest of the Great Library ' s sublevels became tomblike , preserving the ancient tomes for millennia . By the time of the Galactic Civil War , Odan - Urr ' s skeleton still remained sprawled at the feet of his great chair in his office , while two stone guardians stood as silent sentinels to protect the chamber from intruders . Layout . The Chamber of the Antiquities was a sprawling level of the Great Library , with a main corridor winding its way from the dedicate turbolift at one end of the level to the other . Off of this tall , wide corridor were several collection rooms , analysis chambers , alcoves , and offices . Near the main entrance to the level was the working office of the Keeper of Antiquities . A circular chamber with a domed roof , the center of the room was filled by a giant stone chair ; the back of which reached the ceiling like a pillar . On either side of the room were two stone guardian s , droids disguised as statues , standing ready to defend the room should it fall under attack . Midway through the main corridor was a guarded entrance in the form of a rotunda that apparently had no way forward . Hanging on the walls were four tapestries depicting four of the traditional five precepts of the Jedi Code . To find the door , one would have to rearrange the tapestries in the correct order of the traditional mantra . Following the correct order , one would need to recognize that the tapestry depicting a group of children listening to a lecture , the tapestry of the second precept : " There is no ignorance , there is knowledge " , conceals a clue as to its importance . Following the line of sight from the children in the tapestry , one could find the brick in the wall which concealed the access to the rest of the corridor . Farther down into the most secure portion of the Chamber of Antiquities were two vaults . The first was known as the Vault of Justice , which contained an ancient artifact known as Neer ' s Gauntlet ; the second vault held the Greelwood Saber , a lightsaber crafted by Master Oorrl Morm .
