So do we know the premise? After trailer

It seems from what the menacing voice said, the forerunners are trying to wipe out the humans because they’ve become the most powerful force in the galaxy?

I doubt the Forerunners as a whole believe what the Didact is saying. Thirsday War says he was locked up intentionally on Requiem. Could just be the rage of an insane Forerunner who lost literally everything he held dear and is on the verge of losing his own moral code about being the defender of the galaxy.

The trailer shows that the Didact is the main antagonist, that’s all. The trailer doesn’t reveal much, if anything, substantial.

Well, since he did fight the humans a long time ago, he knows the threat they can be. Now that he is out, maybe he sees the current humans to be similar to the old ones, growing across the galaxy and taking every planet they can find. That is the reason for the old war, the humans were getting into Forerunner territory.

I wonder exactly what he means by the forerunners have returned?

True cause was the Flood. The Forerunners also took worlds from their inhabitants, so he doesn’t have much of a high ground on morality.

Only because the flood was pushing humanity into forerunner territory. Which they didn’t like(but were also unaware at the time) the didact even said he deeply regretted his actions towards humanity.

That got me wondering too. Are there other forerunners? Or does this support the theory that they are indeed forerunners stored in machines

But remember when Spark said in CEA Terminal #8:

> But if something were to go wrong with one of the Halos. If our tools were ever turned against us… Long plans indeed.

ONI has control of 3 Halos (Installations 03, 05, and 06). If the Didact knows this (how did he find out?), then it would be his job to to stop them. And with his rage, he may show no mercy whatsoever.

Yes but if the humans are again still overstepping their boundaries you can’t expect the forerunners to be happy. All he said is still true.

The Forerunners left behind all of their stuff for humanity as Reclaimers, the Halos included. The Didact was seen as a threat by the Forerunners and was locked up on Requiem.

Then why assume Humanity is the biggest threat in the galaxy unless of this reason? Without those Halos, Humanity (as of right now with the end of Human-Covenant War and all) aren’t much of a real threat.

Because he is insane? We won’t know for sure until we play the game or read Silentium, but considering he was left in a Flood-infected star system, fair bet on the “insane” option.

Yeah, that does make sense. But simple sense. I would think his motives are more in-depth than just insanity because of isolation with the Flood. Which sounds like good motivation of course, but not in-depth as much as I thought it would’ve been. Hoping it’s more than just that in Halo 4/Silentium.

Oh I’m sure there is more than that, I mean he is really a tragic character all things considered.

I’m surely hoping you’re right.

Yeah, for an awesome Forerunner Promethean Warrior, his story sure is… different. And in-depth!

Of course, I also hold my alternate theory on the Didact to be a possibility.

Chief wakes up because of requiem being close by.
They are sucked into requiem.
Chief has no idea what is going on.
Chief accidentally while trying to figure things out awakens the ancient evil.
Ancient evil hates humans.
Acient evil wants to destroy all humans.
Chief now has a new purpose, that is, to destroy ancient evil and save the human race/universe.

By the rings o_O

I’ve killed so many of them, just out of a pure fun beat downs and bullet spraying…

Caboose: Buttons!? I love buttons! Beep boop beep!

Master Chief: Buttons? I guess I’ll just press these…

Caboose Logic. Destroying Humanity since 2003!

After thinking about the Didact’s motivations more, it would seem at the very least possible that his hatred of humanity could be reignited. Having fought them in a very long war and losing his children (IIRC)to them, it is possible that he just hid his emotions during the events of Cryptum. Then perhaps during his exile on the Flood infested system he learned (through maybe a Gravemind or even Faber) that humanity had developed a cure to the Flood and refused to share it with the Forerunners**. Looking at the galaxy he once knew crumbling around him, it would only seem rational that he would blame the epidemic of the Flood on humanity’s selfish decision. Knowing that the Librarian would plan on saving/ cataloging humanity, the Didact may have somehow escaped to Requiem to wait out the effects of the Halo ring and to some day repay humanity for their selfish mistake. After all, they were her favorite, and would most likely assume the Mantle after the Forerunners’ time had ended.

**It is not entirely out of the question that one of these individuals would lie about that to either tear down the Didact further during his defeat or to prompt him to brash action.
