Flood Galaxy

The Flood Galaxy is a Galaxy that exists in The Universe. It is, as its name suggests, home to the Flood, a parasitic life form created by the Precursors from their own bodies and left to roam the Universe, creating their perfect socialist society wherever they went. The Flood Galaxy is actually just a theory, it is assumed that the Flood control many Galaxies, however, Gravemind states that he has consumed an entire Galaxy in his conquest, so we must assume that there is one somewhere.
