I really dig the idea of Iggy being Luna and Ravus's long lost illegitimate brother. I am also a happy ending trash panda!
Noctis manages to defeat the starscourge without such massive losses (due to handwavey reasons), so his wedding is going ahead when Ignis's heritage is revealed. Luna and reformed!Ravus are genuinely delighted with the news that they have a little brother.
They turn into the biggest pair of overprotective siblings in existence; trying to get Ignis to eat more, telling him not to work so hard etc. Ignis is a little terrified!
+ Luna wants Ignis to be part of her wedding party now that she knows he's her brother. Noct indignantly replies that "Hey, he's MY brother too!"
++ Ravus quizzes Gladio on his intentions towards Ignis after seeing them kissing.
+++ Gladio and Prompto winding Ignis up by constantly calling him "your highness".
Tenebraen!Iggy in a happy ending AU
