Biography
During the Requiem campaign, he was assigned to the Refuge. While he was there he studied Requiem's portal system along with Dr. Leslie Boyd. At some point they requested Fireteam Crimson's assistance, soon after an attack by Prometheans started. During the attack he identified the device that opens the portals, which allowed Crimson to turn off the portals in the area, halting the Promethean attack.
