Speaking of recent ffxv plotbunnies. . .
I kind of want to throw the Dieka verse and the Sentinal!AU together. (Short summary of the Dieka verse: originally a kink meme fill, has spiraled out of control. Dieka is a disabled MT clone Ardyn decided to save from decommissioning. He is devoted to Ardyn and Niflheim, has a sadistic streak regarding enemies, and struggles with being a person instead of a 'trooper. Ardyn and Dieka have about as functional a relationship as two people as fucked up as they are can.)
Dieka is used to being the only one Ardyn actually treats as fully real, the sole being in a universe of paper cut outs.
Dieka would absolutely despise Nyx and Cor for taking Ardyn away from him. That's his king, the center of Dieka's world. (the only thing in Dieka's world) And suddenly - Dieka doesn't matter.
(And maybe Dieka hates Ardyn too. Just a little. For teaching him to be human enough to hurt.)
Ardyn has never loved him the way he loves Nyx and Cor, with fire and fury and such great need that it destroys his composure. And Dieka can't do what Nyx and Cor do for Ardyn, so maybe that's even fair.
But it hurts, and Dieka hates.
