Instant PDF download · Ages 12+ · No app · Organizer plays too

Built for actual gatherings
Give each team a distinct evidence packet. They solve one part of the case, meet for a final evidence conference, and answer four decisive questions together.

Inside the case
Structured evidence, graduated hints, and a fully explained proof chain—designed so the reveal feels inevitable, never arbitrary.
37 pages with setup, six dossiers, a venue map, four team packets, and final accusations.
Three stages per team plus final-conference hints. Use only as much help as the room needs.
A complete five-page explanation and proof chain that answers who, how, where, and why.

Choose by how you will use it
Both editions include the same complete 37-page Game Kit, six-page Hint Deck, and five-page Sealed Solution. The only difference is the license: private play or one organization event.
Private, non-commercial play by the purchaser, household, or invited friends.
One concurrent game for 8–20 participants at one organization event.
Automatic launch offer: $10 is applied at Gumroad checkout for the first 10 paid orders or through September 10, 2026, whichever comes first. No code entry is required.
The same participants should play only once because the solution is fixed. Questions about expanded use should be handled through the storefront before purchase.

Not ready to commit?
The Silent Orrery is a self-contained 10–15 minute mystery for 1–4 players. It uses a different artifact, mechanism, hiding place, motive, and solution—so the full game stays unspoiled.

A fair-play investigation
The layout is atmospheric, but the deductions never depend on color or decorative detail. Teams receive the facts they need—and must decide what those facts prove.


Compare headcount, format, tone, venue, timing, setup, and host role. The tool will recommend another format when Vesperglass is not the honest fit.

Yes. Setup uses the spoiler-free Game Kit. Hints and the Sealed Solution stay separate until the group asks for them.
An ordinary printer, paper, four pens, and four folders or clips. Nothing needs to be cut, hidden, or installed.
Yes. Run four teams of two. At twenty players, use four teams of five. No optional role carries a critical clue.
No. It is a clean gothic artifact-heist mystery with no death, graphic violence, sexual content, or alcohol requirement.
The museum closes in ninety minutes.
