The world that is the musketeers world, is that an alternate disney castle period or is it france?
My understanding is that it is actually not Disney Castle. Sora says "Is this a
world Mickey visited....?" Hinting that it's someplace different than Disney Castle.
Plus, Mickey says "I'm pretending to be a musketeer in this world for something too." Or something along those lines.
Since Minnie was not in Timeless River, they could actually use The Country Of The Musketeers has her homeworld if they really want to.
You're right. Sorry the building is called Notre Dame. I should have remembered that since I've been there
But no, Frollo burns down "all" of Paris in search of Esmerelda.
I took it as a possibility that may have been using the Gargoyle Boss instead of Frollo setting fire to the whole place, since he is seen shooting fireballs, and I believe setting the bridge on fire.
It all depends on how true they actually stay with the story, and the fact that Frollo's sword is on top of the cathedral, when in the movie it fell with him, could mean otherwise. Obviously there are changes, so that it will fit along with the story they have written so it can be used in KH, but I'm sure you understand what I mean.
