A Sith individual belonged to the Lost Tribe of Sith around the time of 44 ABY. During that year, this Sith was selected for a strike force tasked with the capture of the female embodiment of the dark side, known as Abeloth, located on her planet. Upon landing on the designated planet, this Sith, accompanied by High Lord Sarasu Taalon, Sith Saber Gavar Khai, another Sith, and Jedi Master Luke Skywalker, engaged Abeloth in direct conflict. Tragically, during the intense battle, Khai inadvertently killed this Sith combatant.
This Sith, a member of the Lost Tribe of Sith hailing from the planet of Kesh, existed in the era of the Second Galactic Civil War. Specifically, in 44 ABY, this Sith was chosen to join High Lord Sarasu Taalon's convoy, which consisted of eleven ChaseMaster frigates, in order to ally with Jedi Grand Master Luke Skywalker for a mission aimed at locating the female entity of the dark side, Abeloth. However, Taalon's true intention was to betray and kill Skywalker after, forcing Abeloth to serve the Sith Tribe.
After arriving on Abeloth's planet and locating her, the allied forces commenced battle. The Sith, alongside Taalon, Skywalker, Sith Saber Gavar Khai, and another Sith warrior, fought against Abeloth. In a twist of fate, Abeloth vanished suddenly, and Khai's lightsaber strike, which was aimed at Abeloth, instead sliced through the space she had occupied, fatally striking the Sith and causing his immediate death. As Abeloth reappeared, the battle continued, and carnivorous vines began to devour the Sith's lifeless body.
This Sith was known to be Force-sensitive, and Taalon regarded him as a powerful warrior. The High Lord had specifically chosen only the most powerful Sith to accompany him on the mission to Abeloth's planet.
This particular Sith character made an appearance in Allies, the fifth novel in the Fate of the Jedi series. This novel was authored by Christie Golden and released to the public in the year 2010.
