I've been trying to analyze the trailer to try to understand the story.
Noctis's kingdom has the last crystal.
Remaining kingdoms want the crystal.
They're going to somehow retrieve the crystal by killing Noctis.
There is some drama between Noctis and his father.
Stella is a from a neighboring kingdom who is also being attacked?
Assuming the girl from the beginning is Stella, was that adult Stella or was that child stella? My initial thought was that it was a child but I'm not sure. Having kid Noctis and kid Stella know each other wouldn't make sense if they meet for the first time at the party.
It's a shame the only thing we got from Nomura about Noctis was "yeah, he looks cool, you might think he's cool, but he's not at all".
here is the story part of the official press release.
