From the back of the book: Seven Sinful Swords Stolen A powerful seductress has stolen seven mighty blades, each tied to a deadly sin, and secreted them away to her monster-infested dungeon. Located in Kaer Maga, one of the most dangerous cities in all of Varisia, the trap-laden halls must be overcome before the sorceress can bind the swords to her will and gain unimaginable power. Seven Swords of Sin is an extremely deadly dungeon adventure for 7th-level characters, compatible with the world's most popular fantasy roleplaying game. This adventure includes details on Kaer Maga and the labyrinth that lies underneath. The characters must venture into the city of criminals, find the dungeon, and stop the sorceress before she can complete her ritual to unlock the power of the swords. This adventure was developed from the Paizo Dungeon Delve that ran at Gen Con 2007, and features rooms designed by the Paizo staff. Kaer Maga is located inside Varisia, the setting of the Rise of the Runelords Pathfinder Adventure Path.
