Prompt template
Generate {{count}} original story premises in the {{genre}} genre.

Setting: {{setting}}
Protagonist type: {{protagonist}}
Hard constraints every premise must obey: {{constraints}}
Tone: {{tone}}

For each premise give:
1. Title
2. Logline: one sentence containing a character, a want, an obstacle and what is at stake
3. The twist or complication that makes it fresh
4. The first scene in two sentences
5. Why it fits the constraints

Make the premises clearly different from each other in structure and stakes, not variations of one idea. Avoid the most common tropes of the genre unless you subvert them. After the list, name the one premise you think has the most room to grow into a full story and say why in two sentences.
Example output
**1. The Last Mile of Tide Street** Logline: A retired courier with a bad knee must carry one final parcel across a flooded market town in three days, or the neighbour who trusted her loses his stall and his home. Twist: The parcel is empty; the recipient only needs the town to see someone carrying it. First scene: Mara hears the old dispatch bell and knows she is being called back, which she swore would never happen. Her knee says no; her pride says yes. Why it fits: Three-day clock, no chosen one, and the recipient, a boy who communicates only by tapping rooftops, never speaks. **2. Salt Ledger** Logline: A courier discovers the market's debts are kept in a script only she can still read, and someone wants the ledger drowned before sunrise on day three. Twist: The largest debt on the page is in her own name. First scene: A customs clerk hands her a wet receipt in her late mother's handwriting. The clerk, who never says a word, points at the total and then at her. Why it fits: The whole plot runs inside three days, no prophecy is involved, and the silent clerk carries the story through gesture. **3. The Ferry That Wasn't Late** Logline: When the market's only ferry arrives on time for the first time in forty years, a skeptical courier suspects the schedule has been rigged, and the proof could sink her oldest friend. Twist: The ferry is on time because the tide has changed course, and no one wants to admit the city is sinking faster. First scene: Mara checks her watch twice on the pontoon and frowns. Behind her, the ferryman tips his hat and says nothing, as he always does. Why it fits: Three days of rumour, a silent ferryman, and a heroine who is just a tired woman with a stubborn knee. **4. Lantern Season** Logline: During the three-day lantern festival, a courier agrees to smuggle a stranger's grandmother out of town, and must decide how much of the truth she owes the child who does the talking. Twist: The grandmother is not who the stranger claims, and she has been delivering messages herself for years. First scene: Mara loads a cushion into her skiff and a small woman sits on it without a word. Fireworks light the water pink. Why it fits: One silent character, a festival that ends on day three, and no chosen-one destiny. **Strongest candidate:** Premise 1. Its ticking clock and quiet emotional reveal give it a clean three-act shape, and the empty parcel leaves room for comic set pieces on the water.

Why it works

Specific constraints produce sharper ideas than a bare genre request, and asking for a twist and a first scene tests whether each premise can actually start. Re-run with the same constraints and a different tone to get a new batch.
