Ghosts of Graygrim

From publisher blurb: A Swords & Wizardry Mini-Dungeon For 4-6 Adventurers of Levels 8-10 The ruins of Graygrim Manor sat silent for years. Now sounds drift from the ruins at night that suggest they may be haunted. And travelers to the sleepy town of Shadywood have begun to go missing. Again... Ghosts of Graygrim is part of 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.
