How did the flood survive the first halo fire?

So i’m in the process of playing thru Reach - 5 in prep for H:I. Watching the vids and cutscenes on 2, and I know I have a pretty big hole in my lore. How did the flood survive the first firing of the Halos by the Forerunners?

“The arrays have successfully completed 1.3 trillion simulations and 1 actual activation” - 343 GS

The Flood was destroyed, but there were still some specimens stored for study and species preservation by the Librarian and her workers. During CE, the Covenant came across one of these storage facilities and thought, “Hey, that’s new and potentially dangerous. But it’s in the way of the Great Journey, so let’s break it.”

Ah i see. TBH the library is still one of THE HARDEST levels.

This is what we in the business like to call “An incredibly stupid decision”.

Yeah, I never understood that decision. Why keep any trace of something that grows uncontrollably by infecting other species?

kinda like the ending in mass effect. Why kill only the advanced races? you know it’ll happen again and again and again. Poor planning on the villains.

Common misconception: the Halo array doesn’t kill all Flood: it kills all life with sufficient biomass to sustain the Flood (and presumably the larger Flood forms reliant on such biomass - e.g. Combat, Pure, and Gravemind forms).

The Forerunner Trilogy and Point of Light provide good context here.

Because the Flood threat originated extra-galactically and in fact was pushed back out of the galaxy once already the Forerunners did not anticipate that the firing of the array would entirely eradicate the Flood (potentially even within the galaxy - c.f. above and the Flood surviving in non-R&D facilities like Etran Harborage and even Covenant concern that the Flood may be present on Harvest).

On the basis that the Flood may return after the array’s firing the Forerunners dedicated a lot of research to trying to discover cures/immunity/defence. A huge amount of effort went into trying to discover ancient humans’ seeming immunity tonthe Flood (which appears to have been a hoax), but the Forerunners were willing to take the hail mary.

Right, sorry poor choice of words. It destroyed all “sentient” life.

All good. I think it’s a mix of the neural complexity of ‘sentient’ and intellicent life and e.g. the biomass of e.g. the deer and rhinos from the Infinite engine demo

right - though who knows when those life forms entered the ring. Was it the handy work of the Librarian, or were they not affected?

Well she did certainly make the arrays (both neoteric and original) be part of the consevation measure - hence the human presence on Zeta Halo

In Halo CE terminals it explained by 343. Storing Flood samples to study, if the Halo arrays failed to stop the Flood or eradicate them completly which means… can’t recall, but the reason they keep samples from the Flood: to study and find any/alternative solutions to stop them, if they emerge again.

Also how the Gravemind survived? Or he was a sample too? I mean hi was too big and evolved for that. A few dozen spore is OK, but a Gravemind…

The Gravemind didn’t survive, however the knowledge of a Gravemind is not lost when you destroy its physical form: it iteratively adds each time

Then how the Gravemind exists or the breakout like it happaened on Installation 04 created the Gravemind? also how he “eat” the monitor and Regret, who have been killed!
I’m a bit new in Halo Universe, only played the MCC, Spartan Assault-strike games and saw all 4 movies. I have so many questions about the halo Universe.

There is much evidence that The Primordial (possibly the last Precursor) may have been the first Gravemind. In any case there would certainly have been a major Gravemind at the end of the Forerunner-Flood war before the firing of the Halo array.

The outbreak on Installation 04 never reached Gravemind state - Keyes was part of a proto-Gravemind in its early stages. On Installation 05, however yes is did reach Gravemind proportions. The Flood can infect recently deceased corpses and reanimate them - as with Regret.

2401 Penitent Tangent was captured by the Gravemind and may have been subjected to the Logic Plague - by comparison he wasn’t ‘infected’ per say but he likely gave up important information and access to the Installation’s systems (as Cortana gave up the location of Earth in Halo 3)

Thanks for infos! I just want to more dwelve into the wolrd of Halo.

it’s also interesting to note in H4 you meet the librarian and find out about her plan, which implies that there’s a way to survive the firing of the arrays.

Yep, you’re right. The Forerunners built Shield Worlds for this very purpose. As the name implies, these are planets protected from a Halo firing it’s main cannon. Requiem happens to be one of those worlds.

The flood cannot be killed completely. Ever. The humans ( I say humans but we all know its oni) only compounded the forerunners mistakes and kept samples themselves. Plus the floods airborne so one spore will probably survive. And of couse the covenant have to open every sample chamber saying “this uh, it uh, says…” think a something or ill lose my job “uh you must overcome what is inside to complete the great journey and … stuff, cause the forerunners left us trials and things… can i go now? i gotta bad feeling.” The fact that we’re going to be playing on zeta halo means we’ll probably see flood as this was the oldest halo and most likely to have flood escaped. I mean i dont think the banished would open a sample chamber but they’ve like destroyed part of the ring so…

Morseybaby bravo bravo! The dude knows his stuff.its always nice to see another soul who doesn’t just play the games and call it good. Im a lore person to but i do have one question, i literally can’t understand like 25% of the forerunner trilogy. Am i the only one or are there other people out there?
