Wilmon was a Ferrixian salyard worker who didn’t say much, but noticed a lot. Bix Caleen occasionally came to his father’s business, the Repaak Salyard, to use a hidden communication node to get in touch with a mysterious buyer. Wilmon was in on the secret.

When Pre-Mor security forces arrived on Ferrix to capture Cassian Andor, Wilmon and Salman were among the first to raise the alarm. They struck metal against metal to warn the town that danger was near. After the Pre-Mor soldiers began to use force, the Paaks freed Bix from their restraints and got her to safety. 

Weeks later, the Empire took an interest in the planet and established a base in a local hotel. The Imperial Security Bureau tracked a communication signal to the Paaks’ salvage yard and arrested Wilmon’s father. Salman was interrogated and killed. As he mourned, Wilmon used salvaged parts and his technical know-how to build an incendiary device. The town reached its tipping point during the funeral ceremony for Maarva Andor. Wilmon, stirred into action by his grief and her last words, threw the device at the Imperial forces and set off a series of explosions. Brasso helped him escape in the chaos and they ran to a transport in Zorby's Western Shiplot. Wilmon fled the planet along with Bix, Brasso, B2EMO, and Jezzi.
