O, Wintry Song of Agony (OGL d20 3.x)
As war spreads across multiple fronts, the heroes gather their allies for an assault on a secret fortress hidden in the frozen north. Within it, Supreme Inquisitor Leska’s Scourge draws power from the suffering of thousands of prisoners and threatens to destroy a city from across the world. This fantasy adventure sends 15th-level characters deep into enemy territory to breach the fortress, free its captives, and destroy the doomsday weapon. It requires a d20 System roleplaying game core rulebook.
