User:XW3 AR3 L3GION/Installation 06 (L3GION)

Installation 06 or Eta Halo is one of the five remaining Forerunner Rings of mass destruction (after Installation 04, 04 II and 05 were utterly destroyed via UNSC and Sangheili forces). Eta Halo was first discovered by the deep space mining vessel or 'Planet Cracker' Nostromo of Ridley Enterprises. The subsequent release of the Flood by a small away team of the Nostromo and later infection of the entire crew led to the Eta Halo Debacle.

The Debacle also re-affirmed the various controversies surrounding the Terrans knowledge of the parasitic creatures and their outlandish claims to being the successors of the Forerunners.
