Tevlun was a male Snivvian who lived during the waning years of the Galactic Republic.


Tevlun raised a family on the world Cadomai Prime and to financially support them, he began working for the Hyperspace Navigator's Guild as a bonded navigator on the planet Nyriaan. Tevlun would operate a laser transport array to allow people to land on the world and for his fourth such landing on Nyriaan, Tevlun was tasked with landing a group of Republic agents, and he rendezvoused with them at Platform Trill 92, in orbit of Nyriaan. However, while he was landing the agents' starship, the laser that was guiding the ship was deactivated.
