From publisher blurb: A Swords & Wizardry Mini-Dungeon For 4-6 Adventurers of Levels 3-5 A forge, thought long abandoned by the dwarves, has become active again. It’s up to the heroes to find out who or what is hammering away in the mountains high above the village of Northrun. The Forge of Shadows is third in a series of mini-dungeons designed to drop into existing adventures or campaigns. Use them as side quests or a way of getting in a quick adventure when you’re short on time.
