The ancient Swords of Sin, long hidden away in remote vaults and guarded by powerful wards, have been stolen and brought together again for a terrible cause. Seven Swords of Sin is a lethal adventure for mid-level characters, compatible with the world's most popular fantasy roleplaying game, and part of the GameMastery Module line. The adventure includes the terrifying dungeon where the swords are hidden and the vile enchantress, Tirana, who governs its cunning traps and monstrous guardians. GameMastery Modules also include four pre-made characters so players can jump right into the action and full-color maps and handouts to enhance play. Only the brave (and perhaps foolish) have any chance of surviving Tirana's dungeon and stopping her wicked plans before she can unlock the power of the Seven Swords of Sin.
