I am doing something different.  Using the same map I used for Keymount as a copy I am going with a sci-fi theme.  For starters I have a floating dodecahedral enclosure that will have a small city area inside and it is connected by a rail and station on the land.  I will add more later.  Dodecadome (map).

The interior of the Dodecadome: This is mostly complete.  The dome features a few buildings, a hangar bay, a research building, roads that criss-cross and overlay, a farming terrace, a suspended warehouse, halls, nooks, flags, and a park above the train station which is kept out of sight.
