Ardyn didn't just take away Prompto after he fell off the train. He somehow got his hands on Ignis, too. And he's lording it over Gladio all throughout chapter 13.

The only real request I have for this is please no non-con or dub-con between Ardyn and anyone. It's just not my cup of tea. I really want to see protective Gladio rescuing his better half. Thank you so much for understanding, anons!
