Muzzer held the position of Grand Moff within the Central Committee of Grand Moffs. He stood among those Moffs who backed Trioculus as he ascended to become the new Emperor.
Trioculus convened a meeting with Muzzer, along with Moffs Dunhausen and Thistleborn, as well as a Grand Admiral hailing from Gargon, in order to deliberate on the acquisition of the Glove of Darth Vader. Sometime following this assembly, Muzzer sustained a gunshot wound to his leg inflicted by Tibor, who served as the personal bounty hunter of Zorba Desilijic Tiure, an incident that occurred when the Moffship drew the Zorba Express into its interior, yet he managed to live through it.
