Forerunner-Flood War[edit]

At the height of Forerunner power, the planetoids in the system hosted thriving colonies and impregnable fortresses, but during the Forerunner-Flood war the system fell before the parasite.[1][2]

Post-Human-Covenant War[edit]

In the post-Human-Covenant War era, the United Nations Space Command found the system, designating Site C to one of a handful of intact Forerunner structures that remained.[1][2]
