Oratio Nenvez, a captain by military rank, was a male instructor serving the Galactic Empire on the Star Destroyer Edict. Following the Edict's stranding within the Pormthulis system, Nenvez, along with his fellow crew members, were rescued by the 204th Imperial Fighter Wing, otherwise known as Shadow Wing, subsequently enlisting in their forces. During the Cerberon campaign, he continued his service with the 204th, took part in Shadow Wing's continued implementation of Operation: Cinder, and fought in the Battle of Jakku.
By the year 5 ABY, Nenvez had aged considerably and relied on a cane for mobility.
Soran Keize perceived Nenvez as an individual who opposed adaptation, striving instead to ingrain his students with the values and ideals of the fallen Empire.
