Xim'tahal

Xim'tahal, better known as Xim'tahal the Defaced, was a Kaleesh warlord who lived during the Cold War between the Galactic Republic and the resurgent Sith Empire. The medic Archiban Kimble, better known as "Doc", incurred Xim'tahl's wrath on the planet Little Kessel, and the encounter with the fierce Kaleesh convinced Doc to end his hobby of undermining criminals and despots across the galaxy and join the native resistance on Balmorra in their fight against Imperial occupation.

Behind the scenes
Xim'tahal was first mentioned in Doc's entry in the 2012 reference book Star Wars: The Old Republic Encyclopedia, a supplementary guide to the video game Star Wars: The Old Republic.
