I'm creating an original Dungeons and Dragons Fourth Edition adventure tentatively called Under the Skyport. The first major battle sequence takes place in an illegal monster fighting pit in Diamond City. I just finished the map for level 1, and I'm thrilled with the results. It's drawn by hand and colored in Photoshop. Expect more maps and keyed encounters as I assemble the story of the Five Fingers Agency and their discoveries under the skyport.
