Shadow from the Stars

From publisher blurb: A Swords & Wizardry Mini-Dungeon For 4-6 Adventurers of Levels 8-10 An evil cult has taken over the Bronze Aerie Observatory. They’ve used the site’s main telescope to fulfil an ancient prophecy, calling their “Dark Lord” down from the stars. The being is trapped inside the observatory, for now. Shadow from the Stars 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.
