Argel Tenn was an overweight balding male Human who dealt in the trade of illegal Sith artifacts during the time following the New Sith Wars. Tenn often dealt with Dark Lord of the Sith Darth Bane, whom he believed to be a simple collector known as Sepp Omek. When Bane requested any object having to do with Darth Andeddu, Tenn brought an aged scroll made of cured animal skin to Bane. The scroll was a religious proclamation that declared Darth Andeddu the Immortal and Eternal king of Prakith. Using the knowledge supplied by Argel Tenn Darth Bane was able to locate the tomb of Darth Andeddu, find Andeddu's holocron, and learn the secrets of transfer essence.
