The submonitor Adjutant Resolution took over as the caretaker of the installation following his superior's destruction. 117649 Despondent Pyre was assigned as the monitor of Installation 07, and would remain in this position until her destruction during a a conflict between the UNSC and Banished that began in late 2559. However, the installation's diameter was reduced to 10,000 kilometers after most of its superstructure was discarded as a result of heavy damage. Unlike the other six remaining Halo installations, which were constructed as a separate array of rings with the diameter of 10,000 kilometers, Installation 07 is the only surviving ring from the original main array of twelve 30,000-kilometer-wide Halos. Installation 07, also known as Zeta Halo, and originally known as Gyre 11, is one of the seven rings in the Forerunners' Halo Array, located in the Sagittarius Arm of the Milky Way galaxy.
