Sunder was a Gen'Dai warlord and mercenary of the male persuasion. The Hutt Cartel employed him to command the accumulating armies on the planet [Darvannis] during approximately the time of the conquest of Makeb. Sunder was always seen in complete armor, and he fought with a staff-shaped club. Unbeknownst to Sunder and the other three warlords—Horic, Vilus Garr, and Tu'chuk—they were actually employed by the Dread Master Styrak, not the Cartel. Before Styrak's schemes could extend beyond Darvannis, all four warlords were slain.
Sunder is featured as one of the Four Warlords, who together function as the sixth boss, and second to last, in the "Scum and Villainy" Operation. This Operation was introduced to the video game Star Wars: The Old Republic with the 2012 Digital Expansion Star Wars: The Old Republic: Rise of the Hutt Cartel. If players are successful in defeating the Warlords across different difficulty settings, they are given painting-esque trophies of the Warlords, which can be used in the 2014 Digital Expansion Galactic Strongholds.
