The Party Was Supposed To End At Midnight.

A Halloween masquerade at Vesper Manor goes wrong when the clock strikes twelve, and the long-dead host locks the doors. Your players have one night to find three enchanted objects and break the spell. Run it as a silly Halloween romp, or dim the lights and play it as proper horror.

"Eight authentic masks discovered within the manor itself! Completely safe, probably magical, and almost certainly not cursed."
Lady Viola Vesper, your host

Ready to play. Give it fifteen minutes before the session and you can run the whole night. The players always know what they're hunting for and where to go next, so the table spends its time being werewolves and ghosts, chasing a living banquet and racing a scarecrow for the last candle.

How The Night Goes

  1. The MasqueradeDancing, enchanted sweets and an overexcited host. The party picks their masks and competes in the Monster Mash costume contest, prize: a Sugar Skull that screams when bitten.
  2. The Masks AwakenThe clock strikes twelve. Fur, fangs and spectral limbs burst out across the crowd, the doors seal shut, and the long-dead host appears, delighted that nobody has left early.
  3. Three Rooms, Any OrderSmug reflections climb out of the Gallery mirrors. The Dining Hall feast stands up and attacks. A scarecrow dares the party to carry a candle through the garden without it going out.
  4. Save The PartyBack in the Ballroom, Merribold becomes the shape-changing Master of Masks, a different monster every turn. Beat him, or break his spell mid-fight, and every guest gets their own face back.

Frequently Asked Questions

How much prep does it need?

About fifteen minutes. Read the adventure summary and the final fight, look over the masks, and it's ready to play. The whole night takes place in one manor, so there's nothing to track between scenes.

What party is it for?

3–6 characters at levels 3–5, in one session of three to four hours. There's guidance for smaller or less experienced parties, plus a way to trim it to two rooms if the session is running short. It's written for D&D 5e, 2014 or 2024 rules.

Can I make it scarier?

Yes. The book shows you how: make the transformations painful, play Merribold as properly sinister, and treat the transformed guests as a real threat. Or keep it light, with transformations in bursts of colourful magic and defeated guests knocked out cold. Pick whichever suits your table.
