We discussed this elsewhere, but for the sake of reference: we determined that the prophecy ignored by past life Hope also foretold the horrible tragedy that befell past life Mutsumi and Mortis's Constellation, and that Hope may have misinterpreted how bad it was/who it was going to affect. I think it's worth examining too how the Oracle higher ups would have interpreted this prophecy as it relates to MutsuMortis's Constellation, and whether or not things were actually supposed to play out like this, or if the prophecy would have been "correctly" interpreted in a way that would have allowed them to mitigate the Tragedy.

Really fun when your state religion does a lot of "interpreting", huh!
