Billed as a "Free Game", this booklet was distributed to game stores as a promotion for the Dungeons & Dragons Adventure Game starter set (2000).

The Caves of Shadow game is only the beginning. In the DUNGEONS & DRAGONS Adventure Game, your heroes will carry more spells and magical weapons into battle against villainous creatures. The only limitations of the game is your imagination.
