Both Halo WIki’s seem to indicate the last few Terminals in Halo 4 (with the Didact composing the humans to make his Promethean AI’s; and the Librarian shooting him and locking him up in his Crytpum) to take place AFTER the events in the novel Halo: Cryptum. I was under the impression the entire Halo 4 Terminal video series took place before Bornstellar… and the Librarian locking him in the Crytpum was the first time that this happened. so in chronological order:
*Forerunner-human war
*Didact defeats Forthencho
*Foreruners are aware of the Floods threat and overwhelmed
*Forthencho, and many humans/Forerunners are composed
*Librarian is horrified by her husbands work
*Didact forcibly mutates himself to prevent himself to be infected (becomes immune to the Composer)
*Librarian shoots and knocks the Didact unconscious, locks him in Cryptum
*Halo Cryptum- is freed by Bornstellar and apart of him merges with Bornstellar,
*Halo Primordium- Ur believed dead
*Halo Silentium- is actually abandoned on some flood planet
*somepoint resealed in Cryptum
*many many many years…
*Halo 4
or am i very, very confused?
The Terminal timeline is pretty confusing, but you can pretty much tell that after the Ur-Didact changes form after the failed procedure to make him immune from the Flood, that is after Cryptum.
I was under the impression Bornstellar was around during the flood threat. I think Cryptum is after the war, but only by about a few years (20-30 maybe). But cryptum can’t be after the Didact was locked up in Requiem, because in Cryptum he was found by Bornstellar on Erde-Tyrene (which if I’m not mistaken is Earth).
I could be wrong, but I think the timeline is more like this:
*Forerunner-human war
*Foreruners are aware of the Floods threat
*Master Builder builds Halos, Didact champions Shield Worlds. Didact loses power struggle, goes into Cryptum.
*Many years later, Bornsteller finds him and awaken him.
*Cryptum, Primordium, and probably Silentium.
*Didact composes humans to get troops to defend against the Flood, Librarian is horrified by her husbands work, Didact forcibly mutates himself to prevent himself to be infected (becomes immune to the Composer)and Librarian shoots and knocks the Didact unconscious, locks him in Cryptum
*Halo 4
The Cryptum seen in Halo 4 is very different from the one described in the book Cryptum. Any scenes from the H4 terminals with the Halo 4 style Didact take place after he is awoken by Bornstellar. The final terminal takes place just days before the firing of the Halo array.
