Meizh Vermel held the rank of colonel within the Imperial Army, serving as a reliable officer under the command of Gilad Pellaeon. In the year 19 ABY, the Fleet Admiral dispatched him to Morishim with the objective of initiating peace talks between the New Republic and the Imperial Remnant. Unfortunately, his CR90 corvette was captured by the Relentless, which was an Imperial-class Star Destroyer dispatched by Moff Vilim Disra with the intention of sabotaging the peace mission. Before his capture, he managed to transmit only a fragmented message.
Vermel was held as a prisoner at Rimcee Station until Pellaeon learned the truth: his ship hadn't been destroyed by the New Republic, but instead seized by Imperial forces. Consequently, the Imperial commander carried out a rescue operation to free the colonel.
In Specter of the Past, Vermel's rank is inconsistently given as both Colonel and Major.
