User:-AR-/Maginot Sphere

The Maginot Sphere, as it would come to be called by Human Historians, was an interconnected network of Forerunner Fleets, Naval Installations, Military Planets, and other strictly military assets that surrounded the inner colonies of the Forerunner Empire during the latter stages of the Forerunner-Flood War. The Sphere was meant as a last line of defence, separating what little of their territory the Forerunner Leadership deemed defensible, from the numerous worlds that were inevitably left to the Flood. Towards the end of the Forerunner-Flood War, the rogue Contender-Class A.I. Mendicant Bias launched a large-scale offensive on the Sphere with Flood-controlled ships under his command, breaking through with sheer force; very shortly after the Sphere was compromised, however, the Halo Installations were activated, rendering the Forerunners extinct, and the Flood an endangered species.
