Stop the Scourge
As war rages on multiple fronts, the heroes call together their allies for a strike against a secret, frozen fortress that defends the Scourge.
Deep in the icy heart of northern Ragesia, the Scourge is Supreme Inquisitor Leska’s greatest weapon: a device powered by the suffering of thousands of prisoners which, if completed, could annihilate a city from across the world.
The heroes must assault this fortress deep in enemy territory, but can they destroy the doomsday weapon before they fall victim to a wintry song of agony?
A 5E fantasy adventure for 15th-level characters.
