From the back of the module:
Your party moves stealthily up the dark hallway. Torn cobwebs dangle from the ceiling; to the south, a huge, iron door creaks eerily in the mysterious wind. A massive iron gate crashes down, blocking the corridor ahead!
Wait a minute. The pencil broke.
Mapping dungeons is quick, easy, and exciting with the 3-D Dragon Tiles. Use the Dragon Tiles to bring your DUNGEONS & DRAGONS and ADVANCED DUNGEONS & DRAGONS adventure to life.
This package contains 51 3-D figures, featuring characters, creatures, walls, and doors. Two sheets of 84 two-sided feature tiles, showing traps, treasures, furniture, and special surprises, are also included. A Dungeon Mapping Grid is provided to help you lay out dungeons quickly.
The 3-D Dragon Tiles also comes with a special D&D/AD&D adventure, "The Kidnapping of Princess Arelina."
Can't find an eraser? Don't worry. Leave the dungeons to us.
