Night Crystal Pass

From publisher blurb: A Swords & Wizardry Mini-Dungeon For 4-6 Adventurers of Levels 2-4 You’ve been hired by Silver Hammer Trading to investigate a river trade route, running through Night Crystal Pass, that has fallen into disuse. Unfortunately, the dwarves they send along as observers have their own agendas. And then there are the goblins... hideously transformed goblins.
