Juvarek was a male individual. He held the rank of captain within the army of the reconstituted Sith Empire during the period of the Cold War that occurred between the Empire and the Galactic Republic. Around the year of 3643 BBY, Captain Juvarek was assigned to the tomb of the deceased Sith Lord Ajunta Pall which was located on Korriban, in proximity to the world's Sith Academy. During the time he was stationed at the tomb, Juvarek's command included Sergeant Cormun and other soldiers belonging to the Empire's Fifth Infantry company of the Korriban regiment. He tasked them with eradicating an infestation of worm-like creatures known as k'lor'slugs by eliminating their egg chambers. After Cormun and his troops suffered significant losses without succeeding in destroying the chambers, Juvarek issued an order for hazard pay to be awarded to any individual who managed to successfully destroy the egg chambers. Cormun was under the impression that Juvarek would be pleased once the chambers were destroyed.
Eventually, a Sith Acolyte originating from the Sith Academy made their way to the tomb and proceeded to destroy the egg chambers, having been enlisted by Sergeant Cormun for this specific task.
