Vanek Synnoran was a Human male who held the rank of admiral in the navy of the Sith Empire during the Galactic War. His flagship was the dreadnaught Impervious. In 3,637 BBY, he was stationed above the capital world of Dromund Kaas, along with most of the Imperial Fleet, in preparation for the Republic attack. During the ensuing battle, he fought the Republic Navy, but ultimately, the Empire was defeated, and the Imperial fleet retreated and regrouped at nearby Jaguada. He debated with other officers and Darth Acina on what to do next.
