Did any of you read Cryptum?
Remember the Precuser prisoner that was the “final Precuser”?
At the end, he joined the flood.
Could he be the future Gravemind from Halo 2 and Halo 3?
The Gravemind says these two sentences: “Child of my enemy, why have you come? I offer no forgiveness, a Father’s sins, passed to his Son.” and “I am a monument to all your sins.”
The first refers to the humans as the Reclaimers of the mantle, but more than that, it refers to the fact that the Forerunners (the Father) killed all the Precusers to the brink of extinction (he is the last remnant) and that is of course the sin of the Father. The Gravemind blames humanity for exterminating his kind.
The second sentence again, refers to what the first did.
I remember the Gravemind saying something about how he and master chief are the same, the last of their kind (Master Chief is the last Spartan II and the Gravemind is the last Precuser), but I cannot quote it.
Now, I know the Gravemind is supposedly dead, but he survived the explosion of High Charity, so… You know…
If my theory is correct, then this could open multiple arcs of story line for the upcoming Halo 4. As we know, we will be fighting “an ancient evil that threatens the fate of the entire universe”. I have a feeling that this “ancient evil” will be either the flood, or the Precusers.
In the trailer for Halo 4 we see the Legendary Planet. To me it seems different than any regular forerunner structures but still extremely similar. Could the Planet be Precuser of origin? Is it just forerunner?
On another subject… The planet reacted to the arrival of the “Forward Unto Dawn” by opening some sort of structure on the planets surface which emanated a blue light. What the hell was that?! Could the Planet not be a planet at all? Could this Planet actually be a Precuser/Forerunner ship of some kind? Could it be opening to let the Dawn, or more importantly, the Cheef in? That would definitely explain why the “Planet” is completely electronic, unlike any other Forerunner made planents which tend to have a more natural surface (referring to Shield Worlds, Halos and the Ark).
TLDR: The Legendary Planet is actually a Precuser ship and the Gravemind is the Precuser prisoner from Halo: Cryptum.
Edit 1: The Gravemind’s conscience may still be alive as there are definitely more flood in the universe. Maybe the next trilogy will explore the returning Gravemind’s past as a precuser.
Edit 2: Please comment on flaws in cannon, we may have found something.
