The Didact being Composed is a fan-theory, one I do not believe to be accurate, because we know the Didact was immune to the Composer, and there is nothing suggesting that multiple Composers firing in unison would overcome that, or even that multiple Composers even fired in that last scene. All we have is the disintegration effect used throughout Halo 4 & 5 being applied to the Didact as he's on a piece of an activated Halo, plummeting to a planet. I suspect that his piece of the Halo fired, and the Didact was simply disintegrated.LionBowman wrote:The Didact was Composed, not killed. It's a common misconception (lots of people who only play the games still have good reason to think he died at the end of Halo 4).SwordlessGoldie wrote:Correct me if I am wrong but didn't the didact die in the escalation comics?NAVY116 wrote:Humanity has not yet obtained the mantle of responsibility, since the created are claiming that they are the masters of the mantle. My theory about Halo 6 is that Cortana will purposefully release the flood in an attempt to subjugate all organic life. This would bring endless opportunities in terms of reintroducing characters to the Halo series. We could see the return of The Didact and/or 343 Guilty Spark
Also a question for everyone, I feel like I remember reading somewhere a while ago that the Precursors devolved themselves into a powder form that eventually became the flood. Is that true or am I way off?
As for the Flood, "devolved" isn't an accurate word for it, but yes, that's essentially true. When the Forerunners attacked and nearly wiped out their race, some of the remaining Precursors underwent a sort of stasis which reduced their bodies into a powdery material. They were meant to regenerate to living forms eventually, but so much time passed that the stasis dust failed or decayed somehow, creating the tainted substance which gave rise to the Flood when introduced into living organisms (which happened after the stuff was found by ancient humanity). You might say that that powder is the "purest" Flood form, though there probably isn't any of it left in the galaxy.
I believe that depiction of the Flood is merely the narrative the Flood propagated to enable it to complete the purpose it was created by the true incorporeal Precursors for. My understanding is that the Precursors are incorporeal, eternal gods, which is why they aren't bothered by any attempts to exterminate them, being as they're completely beyond any attempt to harm. The organic forms exterminated by the Forerunners were avatars, and some of these surviving avatars were used by the Precursors to create the Flood which would level punishment on the Forerunners, and manipulate galactic events to the Precursors' chosen outcome, which is humanity attaining the Mantle.
