Pathfinder: GameMastery Module D2: Seven Swords of Sin

A dungeon adventure for 7th-level characters.
Long hidden away in remote vaults and guarded by powerful wards, the ancient Seven Swords of Sin have been stolen and brought together again for a terrible cause.
Seven Swords of Sin is a lethal adventure that pits players against a vile enchantress, Tirana, in a trap-laden and monster-guarded dungeon. Only the brave (and perhaps foolish) can survive Tirana's lair and rescue the fabled Seven Swords of Sin from her heinous plot to unlock their deadly powers.
Seven Swords of Sin will be released at Gen Con Indy 2007 and will be the featured adventure in the first Gen Con Paizo Publishing "delve" event. Seven Swords of Sin's plot was written by James Sutter but its rooms were written via an internal Paizo Publishing "Deadliest Room Contest" in which many of the Paizo staff collaborated to make the most viscerally pleasing dungeon possible.
If you want to give your players a challenge, run them through the bloodiest, most heinous rooms the Paizo Publishing employees could think of.
