The Flood Halo Gravemind

The gravemind is a collection of the sentience and knowledge that has been gathered by the victims of the flood.

The flood halo gravemind. While only one gravemind is ever seen in the games the title is given to the final stage of flood evolution in which the flood becomes a superorganism. The flood is a highly infectious parasite which is released several times during halo s story. The gravemind starts out as a proto gravemind which is created by fusing the biomass of sentient life and after enough bodies are merged into it it will gain self awareness becoming a gravemind. It is the overarching antagonist of halo.

It is a near omniscient creature with complete control over all flood forms. The gravemind is a parasitic hive mind intelligence in the halo universe. The gravemind inferi sententia meaning thinking dead infrequently referred to as the ancient one and formally known as a compound intelligence is the shared consciousness of the entire flood species which first emerges when the flood reaches the coordinated stage. The flood exists in a fairly stable state in the absence of a gravemind.

A particular gravemind is the secondary antagonist in halo 2 and a main antagonist in halo 3. It was voiced by dee bradley baker. Combat evolved a supporting antagonist in halo 2 and one of the main antagonists of halo 3 alongside the prophet of truth. They lack the ability to coordinate their efforts but the flood will spawn spontaneously and spread by infecting sentient life forms specifically those that are self aware and capable of introspection.

The gravemind is a massive self aware flood form with complete control over all flood forms and all memories of the lifeforms absorbed by the flood.
