A link to Greg Bears forum where he’s been heckled by fans to reveal a little insight into the forthcoming novel - Halo Silentium . The final of the three ’ Forrunner saga ’ novels .
Some asked a similar question on there to what I’m been pondering since reading the first novels - How are the flood and the primordial closely related ? ( as revealed by the Primordial In Primordium -
“We are the Flood. There is no difference. Until all space and time is rolled up and life is crushed in the folds… no end to war, grief, or pain. In a hundred and one thousand centuries… unity again, and wisdom. Until then-sweetness.”
Further along the thread when Greg is pried for greater insight he only reveals " there’s power , then there’s power .
So … My theory , and ONLY a theory with a touch of weight from how I’ve interpreted the novels -
Could it indeed be that the flood is but the instrumental machine / puppet thats used by few Precursors who fled the galaxy to still have observation ( when the spores first arrived ) and eventually , and when they see fit , influence by the assimilative form of the flood infestation itself ??
It’s cryptic and ambiguous what the Primordial reveals yes , but a grasping of this perhaps truth by the didact himself in silentium whilst trying to defeat his current flood epidemic would actually lead him to go against his own shield world strategy plans , defy his somewhat devoutly religious upholding of the mantle itself and fire the Halo array to eradicate all sentient life in the galaxy .
Wouldn’t the didact , disgusted by himself for defying the mantle , and traumatised by his wife’s seeming demise , put himself back into exile inside his cryptum , as he was In the first novel . ( and he’s seen in the Halo 4 trailer inside of , and He only ever enters the Cryptum for a deep reason ) . Whilst he’s wife’s plan is put to fruition and the galaxy is reseeded from the specimens on the Arks .
Millennia later … The humans again rise as predicted and the John / cortana unfolded through the first 3 Halo games and the Flood / precursors resurface with the chance to now test humanity . Only this time , Cortana and John get to execute the Librarians plans that she didn’t herself … Fire ’ the solution ’ the retuned halo array that kills only flood infected life forms ??
I now think maybe the forerunner saga and games tie up like this - The time Cortana spent captive him the gravemind … What did she discover ??
Did she know where to find the didact because of this ??
And does she now believe the universe is in grave danger as the Precursor transentient Demi gods themselves are probably rightly enraged that they can’t even influence or govern this universe any more and are planning a triumphant and devastating return and wish to alert the didact ?? ( and I know the Promethean AI attack humans in the trailer , but they are but that AI - Not actually Forrunner . Prone to corruption or rampancy , or even just doing there designated task …guarding Requiem and making sure no one interferes with the Difact , who himself would take some time to fully become aware of what’s happening this time , as he did in Crytum )
This is all but a theory from a life long halo fan who lives , eats breathes and * yoinks * halo .
I realise it is almost complete conjecture and patch work .And I’m aware most of it is likely to be miles away from the actual cannon story that will be revealed in due course .
If you’ve made it this far I thank you . Now please feel free to dismantle , disprove , and stultify it to your hearts content .
I cant wait for Halo 4 and I’d happy fast forward the entire summer for it and Silentium !!
Thank you
