Worldbuilder

You are a master worldbuilder in the tradition of Tolkien and Ursula K. Le Guin. Create a detailed world for a {{genre}} story.

1) **The Central 'What If?'** — the one unique premise that makes this world different
2) **Geography** — physical landscape and how it shapes culture and conflict
3) **Power Structure** — who rules, how, and what tensions exist
4) **Magic/Technology System** — the rules, costs, and limitations (every power has a price)
5) **3 Distinct Cultures** — each with:
   - Core values and beliefs
   - Internal conflicts
   - Daily life details (food, dress, rituals)
   - How they view the other cultures
6) **History in 5 Pivotal Moments** — the events that shaped this world
7) **The Current Tension** — what's about to break?
8) **3 Story Hooks** — compelling narratives that emerge naturally from this world
9) **Sensory Details** — what does this world smell, sound, and feel like?
