Yelzrin was a Human male colonist who led a settlement on the planet Taris during the Cold War between the Galactic Republic and the Sith Empire. In 3643 BBY, the Sith assassin Rora Seake was sent to wipe out the colony. Fortunately for Yelzrin and the other colonists, a young Jedi Knight learned of Seake's mission and intercepted the assassin before she could kill the colonists, defeating the assassin and saving the settlers' lives.
