Came across this as I was just setting wiki links for a region page.
Under locations, there are broad concepts such as mountains, swamp, river, sewer, etc. listed as locations. Should locations not be for a specific example of each? i.e something like the Himalayas or the Alps are a location, but mountains are merely a concept, they are not a location as-of-themselves.
I'm talking basically the difference between the difference between "a mountain" and "the mountain." "A mountain" could refer to any mountain (a concept, an idea), but "the mountain" refers to a specific one (an actual place).
If there's a reason it's currently set-up like it is, I'd love to know the reason; but I seriously think they need to be re-categorized.
