This action-packed adventure module is especially designed to give beginning dungeonmasters and players help in learning the AD&D® game system.
But don't be fooled by the title! The adventure is far from easy - in fact, it has challenges that can bring the careless character's adventuring career to an abrupt halt!
Filled with surprises and excitement, the adventure is still easy to referee - and during the game, players and the DM alike will pick up tips and information that will prove useful for many games to come!
