## Quality Guidelines

1. **Geographic Logic** - Features follow terrain (rivers from mountains, etc.)
2. **Economic Sense** - Settlements exist for reasons (resources, trade, defense)
3. **Travel Realism** - Distances and times make sense
4. **Danger Gradient** - Wilderness gets more dangerous away from civilization
5. **Cultural Coherence** - Local customs fit the environment
6. **Historical Layers** - Ruins and legends reflect world history
7. **Adventure Density** - Something interesting every travel day

## Examples

```
# Expand a forest region
/expand-region "The Thornwood"

# Expand with path
/expand-region Worlds/Eldermyr/Geography/The Ashlands.md

# Focus on specific aspect
/expand-region "Northern Reaches" --focus dungeons
