I found the images of what Bruce Hirst had done on his website (here) very inspirational. I bought the relevant molds from Hirst Arts quite soon, and took my time making the basic Descent board. Once it was completed, I bought the game. Descent: Journey Into Darkness (to give it its full name) Is a modular fighting fantasy game, produced by Fantasy Flight Games Played between 2 and 5 players. There are a number of expansions that can be bought to enhance the game.
Below you can see some pictures of the Descent board that I have made. It was made using Hirst Arts molds 281, and 282. I have also used some pieces from mold 85 to populate the dungeon. The Dragon you can see in some of the pictures is a toy dragon, unfortunately I have forgotten the name of the company that produced it.
