Except for
- UNSC AI going completely rogue and doing everything from imprisoning people to straight up murdering them (This is NEW. Halo 5 may have laid the groundwork for this with Cortana’s speech, but there was little directly stating to what lengths former UNSC AI would go.)
- Laconia Station’s entire existence
- HIGHCOM falling, with Admiral Osman, Admiral Hood, and Black Box escaping Earth (Again, NEW. We saw Earth get blacked out, we didn’t see - until then - the entire Upper Command of the UNSC get neutralized.)
Cortana’s speech outlines very clearly what the arrangement is. If you’re thinking it’s some big mystery, I would suggest playing the final mission of Halo 5 again.
We have more than enough to extrapolate that. Losing contact with Doisac is not a huge indicator, as galaxy-wide communication was shut down. However no, Doisac is not mentioned at all in Bad Blood; I just searched through it on my Kindle. Neither “Doisac”, “lost contact”, “contact”, or “Brutes” showed any results. “Jiralhanae” turned up only one, and that was a summary of Cortana’s speech in Halo 5. Furthermore, Cortana would not be able to meet with Atriox - even through communication - to demand his submission until he was back in the Galaxy. That didn’t happen until the very end of Shadows of Reach. Their conversation, and thus the destruction of Doisac, must have happened between Shadows of Reach and Halo Infinite.
As well, none of the Banished in Divine Wind would have known this happened, as there was no communication from the Milky Way to the Ark. They cannot know if they don’t receive new. Castor and his Keepers left Reach immediately after Atriox arrived; they would not have been present to even hear that news. There is no plot hole.
Is this idle or ambient conversation? If so I have yet to encounter it at all in-game. All that’s said in the cutscenes is that the Banished will take control of the Ring, make it their home, and never bow to anyone. That the Galaxy will understand their might and all that. Not that they’re wanting to destroy Earth with it. This, as well as releasing the Endless, is the premise of Infinite.
Esparza said that he killed everyone. Audio Logs handed to you at every FOB paint a very different story, and this can be very known to be an over-exaggeration.
“Petty”? Villains or no, having your entire planet destroyed does not invoke petty actions. JFC.
The question is asked plenty, but it’s unnecessary as the answer is freely given. The Banished take what they want, and crush any opposition in their path. If you do not flee, you are destroyed. They wanted the Ark, and the UNSC was in the way. Nothing more. Then they started fighting back, and the Banished met that eagerly. It’s no mystery why and how the Banished operate.
Well, that is something to be explored. But for now, people (often pitched as the “majority of fans”) wanted a story firmly set in the boots of the Master Chief and no one else. Well, the Master Chief isn’t at Earth, or all over the Galaxy, he’s at Zeta Halo. Get comfy, because that’s the story the “majority” wanted.
