A Warmaster of the Flesh Raider species stood guard over the Upper Hollows, a cave complex situated in the Tythos Ridge on the planet of Tython, during the conflict that took place between the Flesh Raiders and the Jedi Order. This Flesh Raider, characterized by gray skin, red eyes, and distinctive white markings across their body, held the title of Warmaster. Donning armor, this warrior wielded a vibrosword as they fought against both the Jedi and the Twi'lek inhabitants of the neighboring Kalikori village. This Flesh Raider had attained the rank of warmaster by 3643 BBY, at which point they met their death at the hands of a young Padawan. This Padawan had been sent to steal weapons from the Flesh Raiders to arm the people of Kalikori Village. After the Padawan prevailed over the Flesh Raider, they made use of the Warmaster's key, which allowed access to one of the hidden weapons caches belonging to the natives.
The Warmaster makes an appearance in Star Wars: The Old Republic, a video game that was launched in 2011 through a collaboration between BioWare and LucasArts. The Flesh Raider is the objective of the Jedi Knight mission entitled "High-Tech Savages," where the villager Moorint tasks the player with seizing the Warmaster's key in order to gain entry to a weapons cache.
