The Hall of Endurance existed within the Jedi Temple situated on Coruscant. Subsequent to Jedi Master Dooku's directive for his newly appointed Padawan, Qui-Gon Jinn, to assemble for training with minimal delay, Padawan Gretz Droom mocked Jinn regarding the stringent nature of his new Master. Jor Aerith, Droom's Master, heard his remark and instructed him to convene with her at the Hall of Endurance with even less time to spare. Droom started to challenge the imposed timeframe, but then ceased and rapidly departed to prevent tardiness.
