Wenna'lah was a sergeant in Rusher's Brigade, a mercenary group, during the Republic Dark Age; he was a male. In the year 1032 BBY, Wenna'lah and Rusher's Brigade participated in combat on behalf of the Sith Lord Daiman in a battle against the forces of Odion, Daiman's sibling. In this engagement, Wenna'lah functioned as an artillery observer. After Odion's side brought a Death Spiral assault vehicle into the fray, Jarrow Rusher, who commanded Rusher's Brigade, tasked Wenna'lah with evaluating the impact of the brigade's artillery fire on the Spiral. Wenna'lah communicated back that their attack had no effect, as the Death Spiral had activated its energy shields.
