The Mud King of Stoney Creek

Publisher's blurb: A short adventure location appropriate for character levels 5-7. Beavers have dammed up Stoney Creek... but the villagers who went to break up the dam have not returned. Perhaps something sinister is going on here? The Mud King of Stoney Creek began life as a random wilderness encounter with a troll lair. The Mud King uses Swords & Wizards in the Highlands rules variant, though it is completely compatible with all Old School and Original rules.
