From the back of the book: Two centuries ago, the dreaded secret society of assassins were buried in their mountain fortress. But now a group of miners have uncovered this ancient stronghold, unleashing the evil held within. The shadows of the assassins have been waiting patiently for their freedom to come, and now it has. With their fingers like knives and their hearts calling out for vengeance, they emerge once more into the world. Knives in the Dark is a short adventure module, compatible with both Dungeon World and Labyrinth Lord.
