The hand-painted dungeon rooms were created by artist David Rowe, who is well known in the computer game industry for his cover artwork.
Each of the initial dungeon rooms was painted by David, who started off with pencilled sketches, which were faxed to the producers for approval. Once any modifications had been made, the scenes were painted before being provided for use in the show.
In order to increase the variety of rooms that dungeoneers encountered, the room designs were sometimes repurposed by modifying colours, inverting the image, or by adding CGI elements.
