Build a Coherent World for Your Story

    Help me build the world for my story.

What I have so far (the setting, time period, any rules or details I've fixed):
{{world_so_far}}

Genre and the tone I'm going for: {{genre_and_tone}}
What matters most for this story (the elements the plot actually depends on): {{key_elements}}

Please:
- Develop the elements the story needs — how the world works, its recent history, its social rules, and the sensory texture of daily life — and don't over-build the parts the story won't touch.
- Keep the internal logic **consistent**: if there's magic, technology, or a social system, give it clear rules and limits and stick to them.
- Ground it in concrete, specific detail (sights, sounds, everyday objects) rather than generic description.
- Flag any tension or contradiction in what I've told you, and any place where a rule I set would create plot problems later.

Build only as much world as this story needs — depth where it counts, not an encyclopedia. Keep it original rather than lifting a well-known fictional world. Mark anything you invented so I can confirm it fits my vision. If the key elements are unclear, ask.
