Alvon Zamar was a Moff of Human male descent. He held a position within the reconstituted Sith Empire throughout the duration of the Galactic War.
Following the demise of Admiral Layek Davos at the hands of Cipher Nine on Hoth, due to his corrupt actions and seeming disloyalty to the Sith Empire, Moff Zamar faced the immediate challenge of locating a substitute to command Imperial Search and Recovery. Although the Empire's preparedness had been jeopardized, Zamar praised the Agents' handling of the matter, expressing a preference for prior consultation.
In 3640 BBY, during the battle that took place on Corellia, Alvon Zamar received instructions to oversee the Dark Council's occupation. Cipher Nine assisted him by strategically placing multiple landing beacons throughout Labor Valley, compelling Zamar's skyhopper to make an emergency landing. This allowed the agent to extract the Moff from the Republic Special Forces Division who were actively assaulting his crashed vessel. Ultimately, Cipher Nine brought about his death during the conflict.
