Iris has had a crush on Noctis ever since they first met as children, but knows their stars are not meant to align and thus vows to never act on her unrequited feelings.

Noctluna is the het ship between Noctis Lucis Caelum and Lunafreya Nox Fleuret from the Final Fantasy fandom.

It was due to Noctis being attacked by Marilith, the snake daemon that was explored in Brotherhood. The Platinum Demo was Noctis dreaming while in comma due to said attack. After he awakes, he recovers in the wheel chair.

Dude, Noct is dead. He got stabbed through with his fathers sword, unlike where the others kings just kind of flew into him his dads spirit picked up his physical sword and rammed it into his chest, you can even see him impaled by it on the throne for a bit before it moves into the afterlife part.
