River Era: Valley Years
Scrub an authored river settlement timeline from camp and farms to town, workshops and speculative towers. Actual seeded geometry changes reversibly; boats and vehicles follow the same river and bank equations. This is an illustrative sequence rather than predictive history.
Bring a valley, six illustrative eras and optional palette. The Skill returns a downloadable Skill, interactive demos and example videos.
How it works
Generate a project and edit validated bilingual valley data.
Build offline HTML and verify actual geometry, native scrubbing and reversible capture.

Frequently asked questions
Does it need a key?
No. It runs offline without runtime model calls.
Is this a history or economy simulation?
No. The six eras and building schedule are authored illustrations. No population, economics or historical accuracy is calculated.
Does reverse time change actual buildings?
Yes. Visible groups, heights, roofs, towers and routes derive from progress; the result does not depend on earlier construction actions.
What can I edit?
Bilingual names, seed, duration, three bounded river layouts and three palettes in valley.json. Traffic follows prescribed centerlines without collision planning.
