The Museum's Unwritten Room
GM book · 1.0.0 · 120-minute plan · 4 players
A room absent from the museum plan opens overnight. Its objects have no labels, and two curators disagree about who is allowed to name them.
Content notice: Erasure of credit and institutional conflict; no real-world culture is imitated.
Before you start
- Read the truth, the two endings and the two final methods.
- Print the player map and seven cards. Keep the cards face down until discovered.
- Use your own rules or the no-dice mode below. Read the opening agreement.
- Review the immediate problem and the compression plan; choose a timekeeper.
What is really happening
Curator Yara removed anonymous makers from the catalogue to simplify an exhibition. The museum’s memory made a room for those omissions. Reconnecting each object to an honest provisional record integrates it; closing the room preserves objects but leaves the exhibition incomplete.
How to play
Use your own rules or play without dice. State the goal, choose an approach, explain a reasonable cost and let the players decide. Plausible careful actions succeed; uncertain actions can succeed with delay, spent supplies or a favour owed. Evidence is always available through its described action. Each player creates an ordinary person with a useful skill, a reason to help, and an item. No character sheet, monster statistics or proprietary rulebook is needed.
Opening agreement · 10 minutes
Take 10 minutes to introduce characters, read the premise and discuss the content notice. Anyone may say “pause”, pass on a description, or ask to move an uncomfortable moment offstage. Agree on no combat and on treating consequences as delay or repair, not permanent harm. Give one player the route map and another the time sheet.
Time plan
Follow both investigations; take the break before the immediate problem.
- 0–10: Opening agreement · 10 minutes
- 10–20: Arrival · 10 minutes
- 20–35: Records and tools · 15 minutes
- 35–50: An independent trail · 15 minutes
- 50–55: Break · 5 minutes
- 55–75: The immediate problem · 20 minutes
- 75–95: The final choice · 20 minutes
- 95–110: Home and aftermath · 15 minutes
- 110–120: Closing and epilogues · 10 minutes
Total: 120 minutes.
When time is short
- Follow both investigations; take the break before the immediate problem.
- At 75 minutes, settle the immediate problem using a safe approach without another roll. At 95 minutes, finish the final method and begin the return.
- With 10 minutes left, first secure the immediate goal: Preserve contested objects separately with a dated research notice. Mark the immediate goal safe only once the people or resource are secured. Then, if no final method was used: Seal the room with a preservation notice and leave space in the catalogue. Mark the fallback method and read the cost ending. Give each character an epilogue; do not bypass the safety step.
1. Arrival · 10 minutes
Place: Museum hall
Read aloud
A new doorway stands between two paintings. Rem’s floor plan shows only a wall.
Run this scene
The room preserves omissions from the records. Closing safely buys time but does not restore the exhibition. Begin with the concrete request in the premise. Ask each character why they care and give them one ordinary useful item. Read both public observations without requiring a roll. Explain that the marked routes are safe to investigate, and offer a choice of the records or the visible trail. Let the group appoint a map reader; do not use hidden travel rolls to block the first lead.
Choices
- Visit Catalogue desk
- Follow the trail to Loading court
If the group gets stuck
If conversation or a test fails, give the public card anyway. A clear sign points to Unwritten room. A missing method can be found again at Display gallery; no character skill is required.
People in this scene
Rem: Keep visitors from wandering into an unlabelled room Offers directions and ordinary transport for news of the outcome. Voice: Patient, concrete sentences; ask one practical question.
Evidence to give
Timeline record: Deleted catalogue numbers reappear as shadows beneath the objects.
Give it: Inspect the visible labelled object. Give its full text automatically; a check affects time or extra colour only.
GM inference: The room preserves omissions from the records.
Fallback instruction: The room may be sealed with a preservation notice; its objects remain intact.
Give it: Inspect the visible labelled object. Give its full text automatically; a check affects time or extra colour only.

2. Records and tools · 15 minutes
Place: Catalogue desk
Read aloud
Tali sorts blank cards from cards marked “unknown maker.” She refuses to let anyone fill them with guesses.
Run this scene
Honest provisional records integrate the objects. The curator is inside the new room. Put the method card and destination note on the table. Ask what the two objects suggest, then answer direct practical questions from their wording. The maker can trade tools for help carrying or recording them, but refusal never removes these public documents. The trail remains another route. A check, if your rules use one, changes the time or tidiness of the work rather than whether this evidence exists.
Choices
- Proceed to Unwritten room
- Compare evidence at Loading court

3. An independent trail · 15 minutes
Place: Loading court
Read aloud
Bex’s crate carries a workshop mark but no signature. The delivery receipt has been crossed out once.
Run this scene
The objects themselves guide entry. A witness independently establishes the destination. Describe the physical trail before asking for a decision. The witness tells what they actually observed and admits what they did not see. If the group refuses conversation, the physical route supplies the destination. Let a character compare the timeline and another trace the map. For a divided group, take one short turn per side, then reunite at the meeting; do not add another travel encounter.
Choices
- Proceed to Unwritten room

4. The immediate problem · 20 minutes
Place: Unwritten room
Read aloud
Yara stands among objects that cast label-shaped shadows. Each shadow points back toward the catalogue desk.
Run this scene
Curator Yara removed anonymous makers from the catalogue to simplify an exhibition. The museum’s memory made a room for those omissions. Reconnecting each object to an honest provisional record integrates it; closing the room preserves objects but leaves the exhibition incomplete. State the immediate stakes and offer both listed approaches. Before resolving action, ask who observes, who acts and who helps. Make any cost visible before a player accepts it. Avoid demanding a special ability or spell. When a plan fails, use the slower listed route and mark its time cost; people remain recoverable. Once the goal is safe, mark the immediate goal safe and continue. A refusal by the keeper cannot hide the marked safety instructions.
Choices
- Let each player choose one supported fact and write a provisional label.
- Preserve contested objects separately with a dated research notice.
If the group gets stuck
Preserve contested objects separately with a dated research notice. Explain a five-minute delay before they accept it; mark the immediate goal safe when the people or resource are secured.
People in this scene
Yara: Admit the catalogue’s gaps and preserve the objects Explains both solutions when the party agrees to protect the immediate goal; the marked instructions are available regardless. Voice: Calm under pressure; admit the decision and its cost.
Evidence to give
Safety marks: A record may name what is known: place, material, delivery date. A maker name needs evidence.
Give it: Inspect the visible labelled object. Give its full text automatically; a check affects time or extra colour only.
GM inference: Resolve the conflict through transparent uncertainty.
Encounter: Agree on labels without assigning unsupported identities.
A delay leaves less time for the final repair or decision. Explain costs before resolving an action.
Approach A: Let each player choose one supported fact and write a provisional label.
Approach B: Preserve contested objects separately with a dated research notice.
4 players: Two pairs take observation and action tasks. Resolve them in two short alternating turns.
Mark the immediate goal safe after either safe approach; a setback costs time, not access to the next scene.
Continue: The final choice
5. The final choice · 20 minutes
Place: Display gallery
Read aloud
Empty mounts wait in the gallery. A visitor asks whether an unknown maker made nothing at all.
Run this scene
Honest provisional records integrate the objects. Resolve the conflict through transparent uncertainty. Reveal the method and fallback together. Ask the group which tradeoff it accepts and give every character a small contribution. Mark the complete method for the first choice or the fallback method for the second. A risky improvisation should inherit one of these outcomes after its cost is explained, rather than create a third unprepared lock. Keep the immediate goal safe. Return by the known marked route; no new location needs to be invented.
Choices
- Reconnect the supported records and open the integrated gallery.
- Seal the room with a preservation notice and leave space in the catalogue.
If the group gets stuck
Seal the room with a preservation notice and leave space in the catalogue. Mark the fallback method, keep the immediate goal safe and read the cost ending. Do not repeat a failed test.

Approach B: Seal the room with a preservation notice and leave space in the catalogue.
4 players: Work in two pairs, one following the method and the other preparing a fallback or record.
Mark the complete method for the first approach or the fallback method for the second. Both allow return and an ending.
Continue: Home and aftermath
6. Home and aftermath · 15 minutes
Place: Museum hall
Read aloud
The museum’s new plan has room for a question mark. Rem pins it beside the ticket desk where everybody can see it.
Run this scene
Choose a complete resolution or a resolution with a cost, then ask the group what happens next. Read the ending matching the selected outcome. Invite each character to add one ordinary detail to the aftermath, then ask the keeper for a concrete next action. Record who accepted the cost and which clues went unused. Spend the last few minutes on one enjoyable moment and one thing to change next time. Characters need not solve every optional inference to earn a resolved ending.
Choices
- Describe who follows up tomorrow
- Ask who helped whom and what it cost
If the group gets stuck
If no method was chosen, first confirm the immediate goal is safe, use the final fallback method and then read the cost ending. Record the unresolved work and give every character an epilogue.

Shadows settle beneath honest labels. The room appears on every map, and the unknown makers occupy a visible place in the museum.
First secure the immediate goal at Unwritten room. Choose this ending only after final method A is used at Display gallery.
Resolution with a cost
A preservation notice covers the doorway. The objects are safe, but the gallery opens with empty mounts and a public explanation of the unfinished work.

After the session
Record the ending, one memorable choice, and any unresolved work. Ask what was enjoyable and what needs to change. The time plan is a starting point; adapt it to your group.
Start at Museum hall. Catalogue desk and Loading court are independent investigation routes; both connect to Unwritten room, which leads to Display gallery. All marked connections are bidirectional. Return uses the known route to Museum hall.
At Unwritten room, the marked entrance reaches the immediate problem. Approach A: Let each player choose one supported fact and write a provisional label. Approach B: Preserve contested objects separately with a dated research notice. Both reach the onward route. Layout is schematic, with no combat grid or movement scale.
