Installation 07, also known as Zeta Halo,[9][11] originally known as Gyre 11 by the Forerunners,[12], and Oth Koronn by the Banished,[13] is one of the seven rings in the Forerunners' Halo Array, located in the Sagittarius Arm of the Milky Way galaxy.[4]

Unlike the other six remaining Halo installations, which were constructed as a separate array of rings with the diameter of 10,000 kilometers,[14] Installation 07 is the only surviving ring from the original main array of twelve 30,000-kilometer-wide Halos.[15] However, the installation's diameter was reduced to 10,000 kilometers after most of its superstructure was discarded as a result of heavy damage.[16]

117649 Despondent Pyre was the assigned monitor of Installation 07 until her destruction during a conflict between the United Nations Space Command and the Banished that began in late 2559.[7] The submonitor Adjutant Resolution took over as the caretaker of the installation following his superior's destruction.[17] It was during this conflict that Installation 07 would once again be heavily damaged, this time purposefully by Created leader Cortana.[18]

History[edit]

Forerunner era[edit]

Construction and commissioning[edit]

Unlike the other six rings in the final Halo Array, Installation 07 was manufactured at the greater Ark instead of Installation 00 or the "lesser Ark". As a result, it was originally three times the size of a normal Halo ring (30,000 kilometers in diameter).[8] Like the other Halos
