Landfall: The Archivist (Sci-Fi Mystery One-Shot)

The ship’s Archivist died last shift. The Bridge calls it an accident. You have one shift to prove it was murder, and to find out what she died to keep secret.

The Archivist is a complete, system-agnostic science-fiction mystery one-shot for a single evening of play. Aboard the generation ship Perennial, three centuries into its voyage to the promised world of Landfall, the careful old Archivist is found dead at the bottom of a shaft, and the case is closed within the hour. You do not believe it. Over one shift, before the body is recycled and the case is sealed, you work the death, recover what she hid, plot the ship’s true course with your own hands, and discover the secret she died for: the Perennial is not going to Landfall, and has not been for a hundred years.

You cannot fix that tonight. But you can prove the murder, look at the truth, and decide what a handful of people do with a secret that could free forty thousand or burn them.

Why it runs well

• One evening, one Game Master, any system. Fully system-agnostic. No stat blocks, no math. Bring the game you already play.
• A fair-play whodunit with a gut-punch. A real killer, method, and motive, all findable, opening onto a truth far larger than one death.
• A villain you cannot solve with a weapon. The killer is not a monster. They are reasonable, frightened, and certain they did the kind thing. The confrontation is a conversation, and it is the most chilling part of the night.
• A choice, not a boss fight. It ends with the players holding a truth too big for one shift, and deciding what to do with the match.

What is inside

The full scenario (read-aloud pitch, GM truth, cast, a four-movement investigation, the climax and its endings), a GM toolkit for running grounded moral science fiction, and print-ready player handouts.

Loved it? The whole ship is waiting

This single shift is the opening of Landfall: Campaign Codex + GM Kit, the full season where the Archivist’s death was only the first thread and the ship must decide what its people are owed. A perfect, low-cost way to try the world before you run the campaign.

The fine print

Teen and up. Themes of a killing and a system-wide deception, handled with weight rather than gore. Includes a safety-tools note. A personal-use digital download.
