Nionbaster AU, in which Nico and Alabaster are mortal lovers, and Aeon, a god. Aeon falls for and courts Nico, who refuses since he already has Alabaster. Aeon respects this and steps away, but he can't help watching over his mortal. Which is how he was there when Nico, badly bruised, injured and bleeding, slowly succumbed to his wounds, on the brink of death. Aeon makes the impulsive decision of making him immortal, which upsets Nico at first because he's under the impression that Aeon separated him from his mortal lover. However, Aeon pointed out that he was to be separated from Alabaster, regardless, and that in him being made immortal, he could still be with Alabaster. (Plus he couldn't bear to watch his mortal die) Aeon offered for him to become his consort, to which he agrees because he feels indebted to him, but under the condition that he was allowed to be with Alabaster. Which is how Nico ends up spending six months in the mortal plane, six months in the immortal plane. Eventually, he falls for Aeon as well while having feelings for Alabaster, and when Alabaster neared the end of his life, Nico offered him immortality as well in the same way Aeon saved him before.
