Talk:Flood
From Halopedia, the Halo wiki
For reference: "You can see how the body's been transformed by the genetic restructuring of the Flood infection. The small creatures carry spores that cause a host to mutate. The mutated host then produces spores that can pass the Flood to others. It is insidious and elegant. As long as any hosts remain, the Flood is virulent." --343 Guilty Spark
