Vargai Javis, a Human male, was the offspring of Karrels Javis, who served as a lieutenant under Suudaa Nem'ro. During the year 3643 BBY, Vargai and his sibling Serjil had an encounter with a Sith apprentice within Imperial territory, which led to an altercation. The Sith fatally wounded Serjil and left Vargai severely injured, resulting in his transfer to the medical vessel Anodyne for recuperation. This event, however, interfered with a secret mission by Imperial Intelligence that involved Karrels Javis, leading to Karrels's death soon after he found out about the incident. To eliminate any potential complications, Vargai was put under observation, and Watcher Three suggested the possibility of having an operative modify the composition of Vargai's kolto tank, thereby prolonging his healing process indefinitely.
