Ignis won't be too detailed about what transpired in the throne room when they write the book. Even after all these years, he still doesn't know why he saw what he did. And he doesn't want to remember it or remember Noct in that way.

"We will make his bright..." Just like the dawn that he brought back today. He's not sure how he, they will make a tomb filled with light but Ignis is sure someone will come up with an appropriate design. The attempt at a joke was weak, yes, but it still has Ignis' lips tilt up a bit. Indeed, he would want a giant bed. Giant bed floating on water so he could fish when he wakes up. Maybe that's why he liked the yacht so much.

"No, it is not wrong. He wouldn't want us to remember him because he died, but because of the time we spent together while he was alive." Ignis places a hand on Prompto's shoulder, giving it a, hopefully comforting, squeeze.
