Little Blue Squares
As a kid, Dungeons & Dragons introduced me to a lot of things, from fantasy books and authors I might otherwise not have encountered to obscure medieval weapons (like the voulge-guisarme) to equally obscure vocabulary (such as dweomer or weal). Reading my D&D books and modules was literally an educational experience and I am not ashamed to admit that many of my adult interests have their origins in things I first discovered through the game.
D&D also introduced me to the idea of using graph paper to make dungeon maps. Pictured to the left is the first dungeon map I ever saw (unless one counts the board to Dungeon!, which I don’t). The map appeared near the end of the blue rulebook included in my Basic Set and depicts one level beneath the ruined tower of the sorcerer Zenopus. As you can see, the map includes a square grid, with each square representing a 10 × 10 area, as was traditional in all the TSR Hobbies versions of the game. My Basic Set also included an adventure module, In Search of the Unknown, about which I talked before and its two-level dungeon exercised an equally strong influence over my young imagination.
I was, of course, familiar with graph paper, having used it in school during math classes, but I’d never seen it used for any other purpose. Consequently, I was a bit surprised to discover that D&D players bought it in large quantities, both referees in creating their own dungeons and players to keep track of their characters’ explorations of said labyrinths, lest they become lost and unable to find their way out again. I may have thought it odd at first, but I dutifully paid a visit to the local office supply store and bought myself a pad of paper so that I could get down to the business of laying out subterranean mazes of peril to inflict on my friends (or their characters at any rate).
