Installation 01

Installation 01, also known as Epsilon Halo to humanity, was one of the seven Halo fortress worlds built by the Forerunners. Installation 01 orbited the gas giant Abellio in the Lugus system, and is managed by its Monitor, 001 Repentant Observer. It is notable for being the only ring to fire twice.
==Summary==
The purpose of Installation 01 was to annihilate the Flood and prevent them from overrunning the universe. In the event of a Flood outbreak, one of the seven installations could be triggered to annihilate all sentient life within 25,000 light years. Once one ring is set off all remaining rings would activate. All seven rings can be fired at once if need be.
==History==
Installation 01 was built circa 100,000 B.C.E. It was activated shortly after by the Forerunners, killing all sentient life in the galaxy and destroying the Flood as well, with the exception of those specimens kept in the Halos for research. As of 2563, it had a record of 1.2 trillion simulated firings and two actual activations.
