Jenson was a male beast master who lived on Corellia during the Galactic Civil War. Jenson was the brother of Jeridel. After the Battle of Yavin, both worked in an illegal lab on Corellia, a lab specialized in bio-engineering creatures through dangerous genetic experiments. In 1 ABY, Jenson was promoted as lead creature handler. However, when he attempted to feed an engineered acklay, it attacked, leaving him bleeding to death. Before he died, he left a message on his datapad for Jeridel. Three days later, a spacer working for Lieutenant Joth of the Corellian Security Force arrived to investigate the lab, Jeridel hired the spacer to search the laboratory to find out what had happened to Jenson. The spacer later returned and informed Jeridel that Jenson had been killed by the acklay.
Jenson's skeletal remains appeared in the 2003 video game Star Wars Galaxies: An Empire Divided, a massively multiplayer online roleplaying game developed by Sony Online Entertainment and published by LucasArts, prior to its closure on December 15, 2011. Jenson was added to the game with the release of the "Publish 28," on April 26, 2006.
Jenson's species was never identified, and as Jeridel's species was randomly generated, it is impossible to deduce the species from their biological relation. However, Jenson was some sort of humanoid species.
