Ahri Raas was a Force-sensitive Keshiri male from the planet of Kesh. A Tyro in the Lost Tribe of Sith, he trained with the Tribe around the time of the Second Galactic Civil War. After taking part in a competition to win an uvak, he befriended fellow Tyro Vestara Khai. Raas and Khai were present when the Tribe first encountered Ship, a Sith Meditation Sphere, in 41 ABY. In 43.5 ABY, shortly after Jedi Grand Master Luke Skywalker's presence was felt by the Tribe, Ship abruptly left Kesh. By this time, Raas had been apprenticed to Sith Master Yuvar Xal.
