Tholme was a Jedi Master during the last years of the Galactic Republic who served in both the Stark Hyperspace War and the Clone Wars. After completing his Jedi training, Tholme served as Jedi Watchman of the Kiffu sector, where he came across the young Jedi hopeful Quinlan Vos. Sending him to the Jedi Temple on Coruscant, Tholme relinquished his Jedi Watchman status in favor of training Vos. Several years later, after Vos's training had been completed, a mishap occurred in which Vos lost his memory. When he had partially regained it, Tholme took it upon himself to help the wayward Jedi, and even took up Vos's former Padawan, Aayla Secura, as his own.
