We already discussed about this (+ Arendelle Castle), and we said no about these locations. The problem is not thay they are not important. The problem is that they are the main location of the world, and that we barely saw others locations in comparison. Each time when the concerned world appears, this location appears as its main setting. So the story of these pages would be the same on the worlds pages, so completely redundant and not useful.

That's also why Underbrooke does not have a page :)
