Maybe the Demise is the end of Eyos. It could be good or bad, depending on what are Eyos’ goals, but according to Maia’s lore her desire to awaken Aperion to prevent destruction in the North was against Eyos’ will, and according to Keilano’s lore the “great one”, which is most likely Eyos’ mind, wanted to unite the abyssians under its will to conquer the surface.
Even restoring the Magmar to their previous integrity and passiveness and reminding the Vetruvians of their spirituality may be a plot to take control of them, since they have the greatest link to the First Blooming and hold both power and knowledge that may be of vital importance. Making Argeon stop warmongering could be meant to remove him from the main seat of events.
I am still unsure about feeding the pride of a Songhai man I can only assume is Kaleos. Maybe the Twilight Springs are vital to Eyos’ plot due to their unique nature that seems to be independant from its star power, and it wanted to pull of a"we can rule together" plot after rallying the Abyssians?
However this undead divine dictatorship may be the lesser of two evils, as Songweaver Euridice’s prophecy (I may have misspelled her name) showed a future with three thousand years of war and another with only a hundred years and a new empire arising from the ashes, abd she choose the later. Or maybe the first part of the prophecy was a lie on Eyos’ part.
Whatever the truth is, Eyos is darker than the codex leads us to think.
