From publisher blurb: The adventuring party has traveled to a dank, foul dungeon -- aren’t all dungeons dank and foul after all? -- on a quest to recover a noble family’s heirloom, a wooden music box. In this D&D 5e adventure, players will encounter different factions at odds with each other: a green hag, duergar, and vampires. It is up to them to decide which factions they will aid and which they will betray on the way to recovering the heirloom. The adventure is designed for a party of four level-six PCs.
