I ran across the concept of the one-hour dungeon from Dyson over at A character for every game who pointed me to the original post at Planet Algol. Since I am a bit of a map geek, this challenge is right up my alley. Since my main tool for making maps is my computer (rather than pen/pencil and paper), I set about making the following map in Illustrator. This is where I was at the 60 minute mark:
The concept is that of a small Dwarven colony (bottom half) and an ancient alien ruin (top half) separated by a chasm. Entrances into the dungeon include stairs to Rooms 1 & 21. Areas marked 35 are bridges that cross over to the ruin. They are in an open cavern where Areas marked 36 represent the bottom of the chasm. Within these areas can be placed several cave openings which function as the lairs for flying creatures who haunt the chasm as well as a means to get to other dungeon levels. Room 45 has a shaft that goes down that serves as access to other dungeon levels as well as an extra-dimesional portal once various items scattered across the ruins are put back in their proper place. The two halves of the dungeon are also separated by secret doors because when the dwarves had to abandon the colony, they did not want others finding the evil the permeates the alien ruins.
