Manyara Abda was an Orbital Drop Shock Trooper assigned to the 7th Shock Troops Battalion. Serving alongside Pete Stacker during the last years of the Human-Covenant War, she went on to serve alongside him in the 7th throughout the post-war until she was killed during the tumultuous Interspecies Union summit of 2574, at the hands of Amber-G330. Learning of her death and the identity of her killer, Stacker was devastated by the event, though he denied knowing the rogue Spartan's identity in order to protect her. However, it would only allow Amber continued freedom to carry out her mal-intended plans.
