There's no need for lenghty articles on any of these locations- there are plenty of sites that do that, and -what's better- of course we all have our tattered, dog-eared copies of the master's work within reach.
The main point of the location pages is their 'What links here' page (see the toolbox; bottom left of your screen). Every time you put a location in double square brackets on a chapter page, a link to that chapter will appear on the 'What links here' page of that location, thus creating an index of chapters in which this location plays a role.
So there really isn't much point in creating a location page for a location that (as of yet) has no role in the interactive story.
This also goes for the characters page.
