Tul'kar was a male Rakata who served the Infinite Empire of his species as a Predor, a military commander. Tul'kar trained the Human slave known as Xesh as his Force Hound, and the young warrior led his master to many Force-rich planets across the galaxy while in Tul'kar's service. In 25,793 BBY, Skal'nas employed Xesh's service in locating a particularly Force-strong world in the Deep Core, and Tul'kar claimed right of conquest for the planet as Xesh was his Hound. However, Tul'kar's warship Devourer was severely damaged upon arrival in the Tython system, and Tul'kar was slain in the chaos by his own Hound, who stole Tul'kar's personal escape pod and escaped the crash.
