: Interesting idea, but I don't think so. Remember that Marathon and PID are
: basically in the same universe (the presence if Jjaro in both of them).
: The "sleeping god" in PID is thought to be a W'rkncacnter, and
: if he wakes up "... you're toast, and so is the rest of the
: planet." Gravemind in Halo 2 seems to be quite awake.
: But it is interesting in the way that the Flood sure seems like the kind of
: monsters that a dreaming god would create.
Look at RED. A W'rkncacnter (from Earth, no less!) dreams up a race of organic monsters who infect their dead enemies and begin to build strange new creatures out of them...
And speaking of building things, even more on topic: the Gravemind is an amalgam of corpses and dead things, drawn together into one superorganism by the Flood. Remember that the Flood possess the memories of their infected dead, too. That's apparently what was happening with Captain Keyes in that giant blob on the first Halo - the beginnings of a Gravemind.
We are the Flood. You will be assimilated. Your cognitive and biological distinctiveness will be added to our own. Resistance is futile.
