Lord of the Rings x Super Mario World
Per the suggestion of @CTRunsThis, via twitter.
I put a walking path in here, but we all know that one does not simply walk into Mordor. I managed to to fit Barad-dur, Mount Doom, and the nine Nazgul, but ran out of room for The Black Gate. It was pretty fun making what, in the end, amounts to an archetypal lava world.
