Hellothisisveryniche but. Hadestown Epic III and Ascended Astarion. Either just recasting Hadestown with Astarion as Hades and Tav as Persephone. Or perhaps a bard Tav (like the one I’m currently romancing Astarion with, *ahem*) singing an old mythic song to their lover who’s lost himself to power and greed.
Just. Thinking things.
