Olmar Grahrk was a Devaronian male and the son of Vilmarh Grahrk's cousin, Holmar Grahrk. He married the daughters of the Yinchorri ruling councilors to forge an alliance between Villie and the Yinchorri. He was captured by the Jedi. While on a Consular-class cruiser, he made the mistake of contacting Vilmarh. Tracing this communication, the Jedi were able to locate the Yinchorri command center.
