Origin of the "second" Gravemind
No one seems to know exactly how the Gravemind came to be on Delta Halo, but given its knowledge and hatred for Forerunners, one good line of thought is that there is and only ever was one Gravemind. After the first firing of the rings when all its food sources were wiped out, its possible the Gravemind came to settle on one of the Rings, attacked the Sentinals and captured the AI, and this led to both its living under the library and the ongoing battles and containment elsewhere on the ring between Sentinals and whatever Flood were left after the firing of the rings plus Flood released from Delta's containment facilities.

Considering the amount of biomass needed to create a Gravemind, its highly unlikely one could have evolved on Delta given the lack of sentient life on the installation and in the entire galaxy. Plus, there's no record of the original Gravemind ever being killed, just denied its food.

In the end of Halo 3, the Gravemind states something like "this is only added time" to my sentence", a sentence that could be its forced dormancy due to lack of food that goes back to the original firing of the rings. Both the Gravemind and the installation AIs know about events that happened during the first firing era, suggesting they were both around then.  We know the AIs were, and it makes sense that the Gravemind was too.

Substance
I'm pretty sure that's the name of the blue planet Delta Halo is orbiting. That's what is says when it mentions Delta Halo on Master Cheif's page(citation needed for that though). I've also read it before on High Impact Halo (highimpacthalo.org). The person who found it found a picture of it and in the file name it said Substance, so it seems logical to assume that's the name. Also, I thought the Arbiter let the flood out when he lowered the sheild. FRAG3TH 01:49, 3 April 2007 (UTC)

Flood Release
How do we know there was a Gravemind on Delta Halo before the Chief first arrived there? I thought the Covenant or Heretics or something released the Flood in 2552. Mr Toad 05:27, 20 September 2007 (UTC)
