Tau (individual)

Xesh was a Force-sensitive Human male who was captured and enslaved as a child by the Infinite Empire of the Rakata species. Branded with the Aurebesh letter Xesh on his face, back, and arms, Xesh was trained in the dark side of the Force as a Force Hound, the personal warrior of the Rakatan Predor Tul'kar. However, he gave himself a new name, Tau, which meant "soul" in his native language, and kept it a secret to all except Shae Koda. Powerful and skilled, Xesh excelled as a warrior, though his friendship with a fellow slave named Trill became a bitter rivalry when the two became Force Hounds. In Tul'kar's service, Xesh discovered many planets with strong Force signatures, and was considered to be one of the best Force Hounds in the entire Empire by the year 25,793 BBY, when he was tasked with finding a Force-strong planet in the Deep Core.

Xesh was successful in finding a path to the world, which was the planet Tython, but Tul'kar's starship Devourer exploded over Tython and Xesh found himself the only survivor—only to be confronted by Shae Koda, Tasha Ryo, and Sek'nos Rath: three young Je'daii Journeyers, members of an order of Force-sensitive warriors, scholars, and healers. Believing the Je'daii to be warriors like himself, Xesh fought them before fleeing into the canyon known as the Rift. However, Xesh's arrival on Tython caused a powerful Force storm that began to sweep across the planet, leading the Je'daii to pursue the dark stranger into the Rift. After witnessing Shae Koda's use of the light side of the Force in defense of her friends, a power that was alien and intoxicating to Xesh, the Force Hound joined the Je'daii in battling a saarl, an enormous creature in the Rift.

Defeated by the Je'daii, Xesh was exiled to the moon of Bogan to meditate on the Force, but his fellow exile, the mad Je'daii Daegen Lok, recruited Xesh in his mission to construct new Forcesabers—the powerful weapons of the Force Hounds. The two escaped Bogan and traveled the Settled Worlds of the Tython system, acquiring the materials needed for the Forcesabers, but Xesh grew more and more uneasy about his "ally" as their journey continued and as they were pursued by Je'daii, among them Shae Koda and Sek'nos Rath. Xesh captured Koda after rescuing her from death on the planet Nox, but Lok's attempt to secure the allegiance of the Twi'lek warlord Volnos Ryo ended in disaster as Ryo turned on Lok and their Je'daii pursuers caught up to them. Convinced by Koda to make his destiny his own, Xesh turned on Lok and helped the Je'daii capture the mad warrior.
