[Once all is said and done, the villain executed, "justice" meted out, anyone checking Room 13 will find it unlocked, just like all the other dead Champions' quarters.
Prompto's room doesn't look all that different from anyone else's. He didn't customize, there are no photos to hang on the walls. There are, however, two things on his bed: An old letter and The Fellowship of the Ring.
His chest is full of things now free for the taking, but stacked neatly on top are a series of letters addressed to his fellow Champions.]
