Choral served as a stormtrooper within Unit Aurek-Four, which itself was a component of Aurek Company. This company belonged to the 501st Legion, which was a part of the Empire of the Hand.
Choral took part in the climactic attack aimed at capturing "the Warlord" on the planet Kariek. During this assault, he remarked that the Warlord's stronghold "resembles something taken from a poorly written myth".
