Category:The Flood

The Flood is the collective term for a species of parasite (or more accurately, an omniparasite - as they can infect any species of sufficient biomass) that was discovered on Installation 04 (Halo) and are now known to inhabit Installation 05 (Delta Halo), as well as the Covenant City of High Charity, and Forerunner gas mining installations around the gas giant Threshold, and Threshold's satellite Basis.
