Dargous Tanmoul, a battlemaster of the Sith and a male, dedicated his life to the Sith Empire. Eventually, he was chosen to be one of the three gatekeepers who resided within the Tascollan holocron.
Tanmoul possessed a very direct manner of speaking, and he enjoyed elaborating on the ways in which the Force could be employed to overcome adversaries. His intention was to provoke individuals through these descriptions, thereby making them more vulnerable to the Dark side of the Force. While capable of being offensive, he held strength and ruthlessness in high regard. The gatekeeper representation of him inside the Tascollan holocron wore dark Sith armor and wielded a sizable Sith sword.
