The following is a collection of comments on quotes from the Greg Bear books “Cryptum” and “Primordium”. There’s a theory included I myself find hard to believe, because it changes something we’ve assumed to be a main pillar of the Halo Univere’s history.
ABOUT THE PRIMORDIAL, THE FLOOD AND ANCIENT FORERUNNER HISTORY:
from Cryptum:
> “Nobody knows its origins, but what was confined here terrified all who saw it. <mark>Millions of years ago</mark>, it was confined in a stasis capsule and buried thousands of meters below the surface.”
>
> “It predated the humans who excavated it. It <mark>predated the Flood</mark>.”
>
> “A Halo released something that was <mark>kept by both Precursors and humans</mark> at
> Charum Hakkor.”
>
> “A <mark>cage built by Precursors</mark>, maintained and strengthened by humans before our
> war with them,”
>
> “Most humans came to believe that the captive was an ancient aberration and had
> been <mark>imprisoned by the Precursors</mark> for just cause,”
>
> "<mark>Was this actually a Precursor, as the humans had at first</mark>
> <mark>believed?</mark> Or was it something manufactured by Precursors—possibly a strange,
> distorted sibling to both Forerunners and humans?
from Primordium:
> “At that time, we did not know — though <mark>some of us suspected</mark> —
> that the Primordial was itself one of the Precursors, perhaps the last
> Precursor…”
>
> “You told me you were the last Precursor. How can you be the last of anything? <mark>I see now that you are nothing more than a mash-up of old victims infected by the Flood</mark>. A Gravemind.”
The Timeless Once/Prisoner/Captive/Primordial is old, dating back into the Precursor days. Initially, humanity assumed that it was a, or even the last Precusor - but after communicating with him that belief changed to the Timeless One being a prisoner of the Precursors.
Now, this doesn’t mean that it can’t be a Precursor (a lot of human inmates in our prisons, right?), but ancient humanity seems to have come to doubt that the TO really was an original Precursor.
The fact that it was imprisoned by Precursors is never contested by the Forerunners, who surely would have noticed the stasis capsule to be of their own work and not the Precursor’s (this said, because I’ve read about the Prisoner being found in Forerunner ruins, don’t remember where - but it isn’t mentioned by Yprin Yprikushma in Primordium).
Due to the TO’s line “There is no difference,” it is commonly assumed that the Flood and the Precursors are one and the same, either always were or evolved over time from P->F. However, there is another possibility:
The TO could’ve left one single word out: “anymore” = “There is no difference anymore”.
I’m talking about the Precursors being victims of the Flood. This makes a lot more sense regarding the TO being imprisoned and hidden in a planetary crust. I can see no reason why “flood-friendly Precursors” would’ve done something like that. Locked inside a stasis field with “no means of communication” and very well hidden on a “lost cinder of a world” (both facts mentioned in Primordium by Yprikushma) it wouldn’t make a good “mole” or “sleeper cell”, further implying that the TO wasn’t left back by his friends.
from Primordium:
> “Look around you! The Primordial is here. The Shaping Sickness is here! Forerunners are dying — but we live on! And that is what <mark>the Primordial promised</mark>!”
> "Besides, the Primordial gave us information, and with it, we saved billions of human lives.”
> (Yprikushma)
Yprikushma’s words indicate that the TO told her something similar to what he tells the Didact next. Forerunners will fall, humanity will rise. She also seems to have made some sort of deal with the TO, whether she knew it or was tricked into. I believe said information, that saved billions, concerned the “cure”, which included the sacrifice of 1/3 of the human population.
from Primordium:
> “Or are you after all only an imitation of a Precursor, a puppet — a reanimated corpse? Are all the Precursors gone—or is it that the Flood will make new Precursors?”
> "Those who created you were defied and hunted,” the Captive said. “Most were extinguished. A few fled beyond your reach. Creation continued.”
> […]
> “Is that to be our punishment?” the Didact asked, his tone subdued—dangerous.
> “<mark>It is the way of those who seek out the truth of the Mantle</mark>. Humans will rise again in arrogance and defiance. The Flood will return when they are ripe—and bring them unity.”
Note how the TO refers to the creators as “Those” and not “we” or “us”. This doesn’t prove anything, but it also isn’t a direct counter to the Didacts accusations.
“The way of those who seek out the TRUTH of the Mantle.” - what is the way of those who don’t seek out the TRUTH?
The Flood will return to bring unity. He says this after mentioning that it hasn’t been decided yet whether or not humanity will fail like the Forerunners. So the Flood will come back for humanity anyway, but then what are the consequences of passing the test, or failing?
The latter is probably what happened to the Forerunners, complete eradication - if we assume that “seeking the truth” goes along with failing. But then: where lies the difference to “unity” that he already promised to be humanity’s fate?
Before I continue, first let’s remember that the Forerunners have a very vague memory of their war with the Precursors, they remember no details at all.
In Cryptum, Bornstellar calls the fight against the Precursors a “sin”, “shameful”. According to him the Precursors left because the Forerunners offended them.
In Primordium the Didact refers to the Precursors as “monsters”, which the Forerunners had to fight, in order to survive.
Those are two very different perceptions of common lore, but as i mentioned in previous posts, the Forerunner-Precursor History, including the definition of the Mantle resembles much more a religious cult than anything else, hence different believes within one system are possible (like catholics and heretics… ehm, protestants).
So let’s take both approaches serious, but not word for word: the core message would be Forerunners went to war against a threat and it was shameful.
This leads me back to the Precursors vs. Flood theory:
The Flood likes to play mindgames. In the games a Gravemind uses MC and the Arbiter to fight a common enemy (343 GS) and from what Yprikushma tells us the Primordial messed with ancient humanity. So why not mess with the Forerunners to trick them into assisting the Flood getting rid of the Precursors. If the Precursors left behind some Gei in Forerunners (mentioned around the same time as the “shame” in Cryptum), this could explain the feeling of shame in Forerunners like Bornstellar.
Additionally, how likely is it that one species (Tier 1-2) alone can win a war (not: resist occupation, but wipe out the superior enemy) against a Tier 0 species like the Precursors? I always had doubts, further fueled by the lack of information the Forerunners carried over the eons of time. The loss of a library in a supernova alone is a bad excuse - there’s more to this.
