Orrimaarko was a male Dressellian who served the Alliance to Restore the Republic during the Galactic Civil War against the Galactic Empire. Shortly before the Battle of Endor, in which the Alliance attacked the Empire's Death Star II superweapon above the moon of Endor, he attended a meeting on board the MC80 star cruiser Home One to plan the battle. He had light brown skin and black eyes, although one was covered by an eye patch.
