1. Arrival · 10 minutes

Place: Dry square

Read aloud

Asha turns a dry tap. Above her, water spills from a rooftop gutter that never used to flow.

Run this scene

The flows were diverted, not lost. Cart distribution bypasses the damaged pipe. 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 Pipe workshop
• Follow the trail to Roof walk

If the group gets stuck

If conversation or a test fails, give the public card anyway. A clear sign points to Valve house. A missing method can be found again at High cistern; no character skill is required.

People in this scene

Asha: Provide water to the dry square Offers directions and ordinary transport for news of the outcome. Voice: Patient, concrete sentences; ask one practical question.

Evidence to give

Timeline record: The low pipe dried on the same night the high cistern began overflowing.
Give it: Inspect the visible labelled object. Give its full text automatically; a check affects time or extra colour only.
GM inference: The flows were diverted, not lost.

Fallback instruction: Public water carts accept the cistern’s drain hose.
Give it: Inspect the visible labelled object. Give its full text automatically; a check affects time or extra colour only.
GM inference: Cart distribution bypasses the damaged pipe.

2. Records and tools · 15 minutes

Place: Pipe workshop

Read aloud

Bo rolls a copper sleeve across the bench. It has the same diameter as the district pipe.

Run this scene

A repair allows equal flow to both districts. The collector is at the valve house. 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 Valve house
• Compare evidence at Roof walk

3. An independent trail · 15 minutes

Place: Roof walk

Read aloud

Wren ties bright cloth around a railing. The roof walk shakes whenever the high cistern hums.

Run this scene

A visible maintenance trail locates Jun. A witness supplies another route. 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.

4. The immediate problem · 20 minutes

Place: Valve house

Read aloud

Jun presses a map against a closed wheel. One line is marked CRACK; another is marked TOO FULL.

Run this scene

Collector Jun locked a balancing valve after finding a crack in the low district’s pipe. His temporary diversion overloaded the high cistern. A sleeve repair permits equal flow; moving water by public carts avoids both pipes but consumes the town’s transport capacity. 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

• Attach the drain hose to carts and open the drain under observation.
• Close the balance wheel, fit the sleeve, then drain the excess slowly.

If the group gets stuck

Close the balance wheel, fit the sleeve, then drain the excess slowly. 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

Jun: Explain his diversion before somebody opens the wrong valve 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: Drain first while someone watches the lip; a closed drain and open balance can force water into the crack.
Give it: Inspect the visible labelled object. Give its full text automatically; a check affects time or extra colour only.
GM inference: Relieve pressure before restoring flow.

Encounter: Relieve the high cistern without flooding the cracked pipe.

A delay leaves less time for the final repair or decision. Explain costs before resolving an action.

Approach A: Attach the drain hose to carts and open the drain under observation.
Approach B: Close the balance wheel, fit the sleeve, then drain the excess slowly.

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: High cistern

Read aloud

The cistern’s overflow lip is already wet. Two arrows mark DRAIN TO CARTS and BALANCE TO PIPE.

Run this scene

A repair allows equal flow to both districts. Relieve pressure before restoring flow. 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

• Fit the sleeve and reopen both balancing wheels equally.
• Keep the damaged pipe closed and publish a cart delivery rota.

If the group gets stuck

Keep the damaged pipe closed and publish a cart delivery rota. Mark the fallback method, keep the immediate goal safe and read the cost ending. Do not repeat a failed test.

GM inference: Cart distribution bypasses the damaged pipe.

Encounter: Choose a fair water supply before the next rain.

The complete method preserves the planned service; the fallback preserves the immediate goal at a visible cost.

Approach A: Fit the sleeve and reopen both balancing wheels equally.
Approach B: Keep the damaged pipe closed and publish a cart delivery rota.

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: Dry square

Read aloud

Carts gather beneath the square’s taps. People watch the first cup fill before they begin discussing blame.

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.

People in this scene

Asha: Provide water to the dry square Offers directions and ordinary transport for news of the outcome. Voice: Patient, concrete sentences; ask one practical question.

Jun: Explain his diversion before somebody opens the wrong valve 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

No new evidence required.

Continue: Read an ending and close the session.

Endings

Complete resolution

Both districts’ taps run at the same modest pressure. Jun posts the crack and repair on the public map, and the cistern stops humming.

First secure the immediate goal at Valve house. Choose this ending only after final method A is used at High cistern.

Resolution with a cost

The carts deliver clean water street by street. The pipes wait for repair, and the town must postpone other deliveries to keep the rota running.

First secure the immediate goal at Valve house. Choose this ending only after final method B is used at High cistern.

• Fit the sleeve and reopen both balancing wheels equally remains for a later visit.
