Quote:
Have you not heard? Though yet confined to the lands across the sea, a terrible phenomenon afflicts our star. They are calling it the “Final Days.”
'Tis said it starts suddenly, a cacophonous keening from beneath the earth. The sound distorts all living things within earshot, and wrests from us control of our creation magicks.
Once that happens, all is lost. Fear, pain, despair...every dread impulse is siphoned from our minds and given substance: an eternal fall of fiery rain; an incessant spawning of nightmarish beasts...
None can point to the source of the phenomenon. 'Tis as if the star itself has fallen ill─as if a force inimical to life now festers and spreads.
'Tis only a matter of time until Amaurot, too, resounds to that discordant squall. You should stay with your loved ones, child... Stay with them...
So I think that quote does not make the point that their creation magicks could not be affected (indeed, his own words contradict that) - all it seems to be saying is that it did not affect their bodies (and souls?) wholesale via transformations because of their denser aether. Emotional states, and yes, seemingly even control over creation magicks, could be affected. The ancients already knew they could accidentally create things sometimes (underscoring once more how natural this ability is to them) – so I doubt the loss of control would even have been seen as noteworthy if it were not for the precipitating factor (=keening) that led to it, as opposed to the usual accidental use of such magicks in situations of panic, shock etc. You could just drop it and attribute the loss of control to the despair - yet this isn't how it's described at all, hence this loss of control seems to be pivotal here as a differentiating factor.
