Yerrix was a Nalronian mercenary, raised on his species' homeworld of Celanon. His background is a mystery to most, but he eventually ended up working for Breggar Lark, a crime lord for whom Yerrix's disdain was only exceeded by his disgust. The Nalron left Lark's service to help out Freyel in overthrowing - preferably killing - the human from Balfron.
After giving Freyel the deed to Kuras IV, Yerrix went into hiding - but not for long. First, he was attacked by Lark's Trandoshan slavers, led by Zsissk Heik; after defeating them, with a little help from a stranger, he took their ship, the Leash, a Helix-class light interceptor. Later, he was tracked down by the bounty hunter Jag'Tai Vroenik, who took a DNA sample to "prove" to Lark that Yerrix had been slain.
He returned to Kuras IV in the Leash to help in overthrowing Lark; he arrived in time to cut off Lark's escape and send him crawling to Vroenik and pirate Arelim Seron; before the criminal could do any more damage, Vroenik killed him. Yerrix, not interested in staying on the frigid planet any longer, spoke with human Eric Noble and Ailon Tieradeff Jaggeron; they were all of a mind to hit the Galaxy as smugglers and fringers. They renamed the Leash the Wayfarer and were off.
Their first real stop was Svivren, where they delivered a cargo from the Hutts. It was here that they met the former Stormtrooper Arlan Hale, taking them on a new adventure...
