Olmar Grahrk, a Devaronian of the male gender, was the offspring of Holmar Grahrk, who was the cousin of Vilmarh Grahrk. In an effort to create a bond between Villie and the Yinchorri, he entered into marriage with the daughters of the Yinchorri governing councilors. The Jedi took him into captivity. During his time aboard a Consular-class cruiser, he unwisely contacted Vilmarh. By tracking this interaction, the Jedi managed to pinpoint the location of the Yinchorri command center.
