Jarastok family

The Jarastok family was a family that lived in the reconstituted Sith Empire. Several centuries before the Cold War with the Galactic Republic, the Jarastok family killed a member of the Eteelan family, sparking a feud that would last until the entire Jarastok family was exterminated by the Sith Lord Darth Baras over the course of a decade, a process that ended sometime before 3,643 BBY. Baras then took advantage of his newfound favor with the Eteelans to set the family upon his own rival Darth Angral.

Behind the scenes
The Jarastok family was first mentioned in the Star Wars: The Old Republic Encyclopedia, a 2012 guide book for the video game Star Wars: The Old Republic.
