On to some more serious analysis here... I'm still not entirely sure what Millium/Claire/Lechter's deal was with this. Those 3 were like... pretty clearly... on the side of Class VII here but fought us anyway. They reference a "truth" that had them sticking with Osborne for this but uhhh... the only thing off-hand I can think of was they were told it was Millium or Altina but that doesn't make sense for Millium to go for, nor does it explain moments like Lechter imploring them to save Altina after they lost. guess it could just be CS4 content but yeah.
don't wanna answer in full in fear of accidentally spoiling, and I don't have time right now to look at the entire speech, but I did check that part and maybe this'll help clear things up:
en: I hope you don't think ill of us. We Ironbloods simply cannot oppose His Excellency. Though this whole situation is unfair, now that we know a piece of the truth, we cannot go against it. jp: Do not rebuke us so. His Excellency simply holds that great a presence in our hearts. Too great, perhaps... And as absurd as this enterprise may be, we have glimpsed enough of the truth to know that we cannot fully oppose its course.
So some differences there... Or maybe that still leaves you confused. I dunno.
Eh, I'd say it leaves me in about the same place, though as always I appreciate the translation.
Basically the most straightforward reading of it is that there's more to the Great Twilight and/or Phantasmal Blaze than has been explained to us but that they heard that has them reluctantly going along regardless of how ridiculous it all seems. I do think that's at least true for Phantasmal Blaze because Campanella was almost guaranteed to be hamming it up and trolling a bit later when he states to Stahlritter/Xeno/Leo that the successful execution of the Phantasmal Blaze plan they've been working towards is the "end of the world." That doesn't square with what we know about Ouroboros. "end of the world" is kinda an endstate and we know Phantasmal Blaze is Part 2 of ?? of the Orpheus Final Plan. So they can't really call ending the world a success because they uh... kinda still have things to do. It makes sense for them to play along for a bit to fully restore the Sept-Terrion but not to go all the way if the world really would end. Specifically if they're after Sept-Terrion there are still 3 they haven't made a move on or mentioned. Not to mention Roselia seemed to imply that the Great Twilight and Phantasmal Blaze had completely different goals... though how she'd be in a position to know that idk.
There was the whole thing with the Ironblood's eyes right before the fight but I assumed that marking was related to that so-called four-way link they claimed to initiated but wasn't reflected in the actual battle. If the "Too great, perhaps..." is suggesting he has some means of control over them maybe that was it but =/ ---
