The Shroud has changed the world in many ways, some profound, but others more subtle. This is the story of how the Shroud changed a man’s beliefs without changing his body. A man named Wilhelm ark-Trasser found himself on a quest that led him into the dark heart of the Shroudlands. There he faced the toughest challenge of all: remaining true to his principles in the face of adversity. The Shroud changed him, and he changed the world. Will the Shroud change you?
Within these pages, you will find details about Wilhelm ark-Trasser and his group of missionaries, called the Purifying Horde. You’ll also encounter three new nonplayer characters, nine new monsters, a new disease called shroudrot, the bizarre device called the shroudmask, and six adventure ideas. All together, it’s enough material to launch a full mini-campaign suitable for heroic tier characters, plumbing the fundamental question: when do the ends no longer justify the means?
