During the Battle of Requiem in July 2557, the area was first reached by Covenant forces that entered the shield world. They started occupying the local Cartographer, but were contained by Aggressor Sentinels. The Covenant entered into a battle with John-117 as he was exploring the planet. John-117 cleared the area of Covenant, moving into the Forerunner structure. He and Cortana accessed the Cartographer before continuing to the Terminus.
Six months later in early 2558, the Covenant had secured this area and had beaten back attempts by the UNSC Marine Corps to dislodge their position. In response, Commander Sarah Palmer sent Fireteam Crimson to neutralize the Covenant. After the Covenant were neutralized, several Prometheans translocated into the area. Crimson fought them off and disabled the Forerunner turrets the Covenant were using. Robert Dalton then sent a Pelican and extracted Crimson after all the foes were defeated.
Later Parg Vol led a Covenant battle group to the position, and Crimson was deployed to neutralize him. After a skirmish, Vol and his Sangheili battle group were all killed. After facing more foes, Crimson left the location. The Gate later housed energy generators for scientists working at the Refuge. Crimson was sent in by Jared Miller to investigate power fluctuations at the Refuge base. After the generators' activation, numerous Prometheans began transalocating into the area, and Crimson defended the generators while Leslie Boyd finished his work on Requiem's Slipspace portal transport system. Crimson defended the generators successfully, allowing Boyd to cut off the Promethean's teleporting. Boyd opened a portal for Crimson taking them to the Refuge.
The back of the canyon at the Gate leading to the rest of Requiem is blocked in Spartan Ops for gameplay purposes.
