Fetzellen was a male Talz who led his clan in the service to the Galactic Republic. Fetzellen had his clan of Talz join the Republic Army as soldiers and they were stationed on the planet Hoth during the Galactic War between the Galactic Republic and the Sith Empire.

Broonmark continued to chase them, killing the Padawan and many Talz while Fetzellen and Xerender made their way to the wreckage of the Star of Coruscant. Accompanied
