[Halo] Would two graveminds that developed independent of each other work together, combine into a singular gravemind, or fight each other to obtain resources the other controls?

There is only one Gravemind, though it may have many bodies. It is the overriding , malicious intelegence behing all flood, linking them together over unfathomable distances through the living consciousness of Space-Time.

Two bodies would work in concert, as two limbs of the same great beast. They could meld, increasing the mental capacity of the Graveminds manifestation, or spread out, so if one was destroyed the will of the Flood would remain manifest.
