Tressk, a Rodian of the male persuasion, existed in the era of the Galactic Civil War. Employed to execute a pair of poachers located on Kashyyyk, he undertook this task to kill. While on the planet, he encountered the lost Rodian hunters near Rryatt Trail and, finding their presence shameful, he contracted a spacer to dispose of them.
The character of Tressk was featured as a non-playable entity within the Star Wars Galaxies video game, a massively multiplayer online role-playing experience. This game was the product of development by Sony and publishing by LucasArts, before its servers were shut down on December 15, 2011.
