An officer of high rank, known as an admiral, functioned as an Imperial officer in service to the Galactic Empire around the time that the ambush at the Zavian Abyss took place amidst the Galactic Civil War. This commanding officer held authority over the Battlegroup Echelon during the Skirmish at Merisee, an event that led to their capture. Ultimately, following a regrouping effort by the battle group, a rescue operation was initiated, resulting in the triumph over the rebel opposition.
