given the aforementioned penchant for jungian bullshit and the many parallels between kiseki and xeno, despite the benevolent depiction of Aidios I have thought of her as something equivalent to demiurge. A false god that controls only the physical realm. We dunno what the GM aims to do lmao, but if she were Emilia, what better way to break free from Zemuria, aka their earthly prison? We have already seen the series literally depict the alchemical process in Crossbell and create a stand in to the Philosopher's Stone in the false septterrion kea.
The GM and Emilia both are possessed with a mercurial spirit. The Eternal Recurrence, the Ain Soph, been closely linked to the failed attempt at destroying or at the very least unmasking the demiurge
