Looking at that, it seems you unlock more future quests after that one as well. Just a feeling. This one ends at the Hill before Insomnia. I wonder if they actually added the ability to travel further???
I remember hearing there is a new cutscene between Noctis and Ravus in chapter 13. I have work tomorrow, so I don't have time to confirm it. But it would be nice if someone could replay the chapter 13 and see if it's true or just a rumor.
