Description

The Flood, (Latin Inferi redivivus meaning "the dead reincarnated") and referred to as the Parasite and the infection by the Covenant, is a species of highly virulent parasitic organisms that reproduce and grow by consuming sentient lifeforms of sufficient biomass and cognitive capability. The Flood was responsible for consuming most of the sentient lifeforms in the galaxy - including the vast majority of Forerunners - during the Forerunner-Flood war in ancient past, prompting the activation of the galaxy-sterilizing Halo Array in 97,445 BCE. Originating as a corrupted form of the galaxy's most ancient custodians (the Precursors) the Flood reproduces and spreads by infecting other organisms, hijacking their bodies and nervous systems in order to transform them into one of many specialized forms.
