Background

Construction and commissioning

Unlike the other six rings in the final Halo Array, Omega Halo 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). Like the other Halos, Omega Halo served a secondary purpose as a Lifeworker preserve for biological specimens from across the galaxy as part of the Conservation Measure. Omega Halo was primarily dedicated to humans, being home to various species and subspecies of the human genus, alongside numerous fauna and flora. The humans living on the installation identified themselves as Tudejsa. These humans were allowed to build their own societies and were mostly left undisturbed by the Forerunners. Some of the humans even managed to construct rudimentary cities.
