Vok Ruvege was often considered to be Sivter’s right-hand man despite the fact that the two were rarely seen together or that Vok was never given the official designation. It is said that Vok and Sivter were imperfect reflections of each other, with but a few differences in their personalities and skills to distinguish them apart. Whereas Sivter was more inclined to come up with multi-tiered plans and grand schemes, Vok focused more on the day-to-day matters. He was eventually killed by Delth Ardin on Chandrila while attempting to assassinate Kalja Sairu Leidias.
