Nightglass: Campaign Codex + GM Kit

The town died under the snow years ago. One man asked the sky to remember it back. The sky is finally finishing the math.

Vesper Combe is a remote mountain town that should not exist. In a long-ago winter an avalanche buried it whole, and an astronomer at the observatory on the hill turned his great telescope, the Nightglass, on something vast and patient between the stars, and asked it to remember the town back into being. It did. The dead stood up, certain they had always been alive.

Now a new star has risen, low and steady, and the town has started to come apart. Not in fire or blood. Quietly. A neighbor is remembered a little differently, then by fewer people, then there is an empty chair no one can explain and a name no one will say. The players are the only ones who notice the holes, because they keep a record the world has not finished correcting. They are about to learn the most frightening thing in the universe is not a monster that wants to eat you. It is a universe that has noticed you should not be here, and is being very, very tidy about it.

Nightglass is a complete, system-agnostic cosmic-horror campaign: a full season of connected disappearances, a fair-play mystery you solve by investigation, and a town-sized choice you cannot make with a weapon.

Why it runs well

• A real mystery, run honestly. The truth is always findable. Every erasure leaves a seam (a contradiction between the players’ record and the corrected town), and the seam is the clue, every time.
• A horror that is not a monster. One supernatural rule, held consistently: the sky erases the town through memory. The dread is loss, not gore. It is quiet, and quiet is where the fear lives.
• A villain you cannot solve with a bullet. The Keeper of the observatory is not evil. She is running the town’s erasure as a kind of hospice, and she is hiding one unbearable, human hypocrisy. The true antagonist is an indifferent sky, and it has no face to hate.
• A clock you can see. The risen star climbs higher every session. A clever table can read exactly how much time the town has left, in degrees.

What is inside

The full Campaign Codex (The World, The Conflict, The Story, The Characters, The Places, Running the Campaign) plus appendices: NPC reference sheets, map notes, and print-ready player handouts. Built fair-play, with a session-by-session season shape, a safety-tools guide for its mature themes, and an example of play so you can feel the investigation before you run it.

System-agnostic

Use the system you love. Nightglass provides the story and the structure; you provide the dice and the rules. No stat blocks, no math to convert, no new rulebook. New to running system-agnostic? It works with any ruleset, or with none at all.

Who it is for

Game Masters who like cosmic horror that is sad and human rather than splattery, fair-play mystery fans, and any table that wants a season of dread with a real choice at the end. A complete kit for a Game Master and any group, about five sessions.

The fine print

Mature cosmic horror: themes of disappearance, grief, memory loss, and implied death, handled with dread and weight rather than gore. Includes session-zero guidance and named safety tools. A personal-use digital download.
