The Darkstalker Files
Undercity, Underdark, Subcity, Darkside. It’s known by many names and home to many dangers.
The subterranean city commonly located under a larger above ground city. Located all over the world, these large areas consist of multiple levels connected by intersecting tunnels, elevators, and corridors. Some were dug out by NHC centuries prior while others have naturally formed by the shifting of the earth’s crust.
Though commonly entered via public pathways and ramps located in Subways and underground parking garages, many Undercities have secret access points.
