This module is based on pre-Columbian Meso-America. Some changes from historical reality have been made to make the transition from reality to fantasy easy to accomplish. It is recommended that the DM research one or more of several historical works in order to more accurately recreate the atmosphere established in this adventure.

This module was originally used for the AD&D Tournament at Origins '79. Your party is lost! You should never have abandoned the ship and struck out into the marshes, but your pursuers were closing on your trail, and it seemed the only way. Stumbling onward through the fens, your party makes for higher ground ahead. As you cross the ridge, you see a clearing before you. There in an ancient ruin - a worn and overgrown pyramid fills the courtyard, shining in the moonlight, seeming almost brighter than the moon itself. TSR 9032
