Devers, a Human of male gender, held the position of Commander within the Rebel Alliance during the Galactic Civil War, acting as a commissioned officer.
He fulfilled the role of tactical officer on the Mon Calamari Star Cruiser Defiance, which was under the leadership of Admiral Nammo, during the period when the warship was attempting to evade the Imperial Navy following the Battle of Hoth. More precisely, Admiral Garreth Holtz was in pursuit of the vessel.
To enlist Ace Azzameen as a pilot of a starfighter for the Alliance, Olin Garn initially needed to secure Devers' consent regarding the recruit. The commander subsequently took part in the Battle of Endor, once more in the capacity of tactical officer.
