United Nations Space Command
Dyer was a first-year officer cadet of the United Nations Space Command. She attended Corbulo Academy of Military Science during the first years of the Human-Covenant War in 2526.
She was present in the mess hall when a fight broke out between Thomas Lasky and Walter Vickers. She joined the crowd observing the fight.
She was presumably killed when the Covenant destroyed Corbulo Academy.
