01 / Fantasy · Investigation

The stolen sunrise

I am an apprentice clockmaker in a town where dawn has stopped arriving. The tower still strikes six, but the streets remain under stars. My teacher disappeared after repairing a watch that runs backward. I want to find them before the town seals the tower. Begin outside the workshop, where someone has left a fresh footprint in yesterday's ash. Let me decide whom to trust and what to investigate.

02 / Coastal fantasy · Exploration

The lighthouse below the sea

I am a lighthouse keeper's apprentice returning to a fishing village. A light shines underwater from a tower lost a century ago, and a boat has returned carrying my teacher's coat but no crew. I want to learn what happened before the next tide. Begin at the harbor with a damaged chart and a fisher who refuses to sail. Leave the cause of the light unresolved.

03 / Mystery · Urban intrigue

A parcel for an empty house

I am a courier delivering a parcel to a house the city records say was demolished twenty years ago. It is standing at the end of the street, and someone inside knows my name. I need a delivery signature to clear a debt, but the parcel has begun ticking. Begin on the doorstep. Give me details to examine without deciding whether I enter or open the parcel.

04 / Science fiction · Suspense

The station with one extra passenger

I am a maintenance engineer on a remote orbital station. The life-support system counts one more passenger than the crew manifest, yet every occupied room checks out. I must find the discrepancy before an evacuation launches. Begin in the control room with an incomplete maintenance log and a request to disable the alarms. Keep my decisions open and give the crew different reasons to worry.

05 / Fantasy · Negotiation

The dragon's unpaid debt

I am a traveling bookkeeper hired to collect a debt from a dragon. The village claims it stole their harvest; the dragon claims the village broke an older bargain. I need to recover enough grain for winter without starting a fight I cannot win. Begin at a bridge where both sides have sent a representative. Let evidence and conversation reveal what each side owes.

06 / Strange fantasy · Character drama

The market of borrowed memories

I am a mapmaker who sold the memory of my childhood home to pay for a journey. Now a stranger is using that memory to find someone I promised to protect. I want to recover it before the market closes at midnight. Begin beside a stall selling bottled recollections. Give each possible bargain a consequence, but leave what I am willing to sacrifice to me.

07 / Science fiction · Discovery

The garden on the frozen moon

I am a field botanist investigating a warm garden beneath the ice of an abandoned moon. Someone has tended it recently, though the last mission left decades ago. I must identify its caretaker before a salvage crew dismantles the habitat. Begin at the airlock with a cracked helmet camera and a plant growing through the keypad. Let me choose how cautiously to proceed.

08 / Mystery · Time and choices

The train that skips tomorrow

I am a railway inspector aboard a night train whose next station appears on no timetable. A passenger carries a newspaper dated two days ahead, reporting my disappearance. I want to reach the conductor and learn where the train is going. Begin in the dining car as the lights go out and someone asks me to hide their ticket. Do not decide my response or reveal the mystery at once.

Imagine the first scene

A simple recipe for a playable premise.

I am [a person with a connection to this place]. I need to [an immediate goal], but [a complication] stands in the way. Begin at [a specific location].

Your possible next move

Give me a situation to investigate and leave my character's choices and actions to me.

Use the template to make your own premise, or adapt one of the eight ideas in this collection.

Write the first problem, not the whole ending

A prompt works best as an invitation to act. Name something your character can investigate, protect, retrieve, or decide. A problem in one street often creates a clearer opening than an entire continent's history.

Leave the solution undecided. If the prompt already says who the villain is, how the hero wins, and what every character does, there is less room for discovery. Give the game a situation and keep your own choices open.

Before you begin

A few useful answers.

Have these exact stories already been played?

These are original illustrative starting ideas, not recorded sessions or guaranteed outputs. The opening and later events depend on your setup and decisions.

Can I change the genre or character?

Yes. Treat each premise as a starting point. Change the protagonist, setting, tone, or stakes to match the adventure you want to try.

Where do I use a copied prompt?

Open Custom World, select New Play, sign in if needed, and adapt your premise in the creation flow. Copying a prompt does not create or start a session.

What if I want a prepared adventure instead?

Browse the world library and read a world's introduction. You can follow that world's setup without inventing a premise yourself.
