Site C

Site C is a UNSC designated location within the Zeta Hydronis Secundus system. At the height of the Forerunner's power, the planetoids in the system hosted thriving colonies and impregnable fortresses, but during the Forerunner-Flood war the system fell before the parasite. When the system was discovered by the UNSC after the Human-Covenant War, Site C was one of a handful of intact Forerunner structures that remained.

Trivia
The Halo 5: Guardians multiplayer map Tyrant is set in and around Site C.
