Alternate prompt from the Kara no Kyoukai prompt above, an AU where the Lucis Caelum family still has magic and things like the Ring of the Lucii, and Noctis is still the Chosen One prophecied to destroy the daemons for good. But instead of kings they're a well respected noble family of professional daemon hunters. Regis doesn't have bodyguards and Noctis doesn't have Ignis taking care of him, he's just kind of a recluse until one of the Chocobros makes the first move and breaks him out of his shell.

Most of the political stuff is still happening offscreen, so other people are getting engaged to Luna and assassinated during the destruction of Insomnia. And Noctis is fighting the daemons on the front lines, fulfilling his destiny a different way instead of being inside the Crystal. Can be either genfic or shippy (prefer Ignoct followed by Promptis), and can have a happy end or a bittersweet one.
