The World

Nimb is a high-magic sphere where weather is not scenery but infrastructure, weapon, religion, and law. Every major spell leaves a mark on the atmosphere, and centuries of magical conflict have carved the planet into strange climates and dangerous wind routes. Renaissance city-states now regulate spellcraft through fragile treaties, while farmers, sailors, raiders, and sky-priests argue over who owns the rain. The current storms are moving with purpose, suggesting someone has begun editing the world’s weather.

The Ages

  1. The Clear Age

    First Era

    Early peoples learned to read the planet’s calm skies, building cities around predictable winds and treating weather as a shared public resource.

  2. The Spellstorm Age

    Second Era

    Powerful mages turned weather into warfare, creating permanent storm belts, fertile rainlands, and dead zones where magic still misfires.

  3. The Charter Age

    Third Era

    Merchant houses and city councils formed agreements to regulate spellcraft, airship routes, and rain rights across the recovering world.

  4. The Broken Forecast

    Current Era

    The old weather treaties are failing, storms are moving against all known patterns, and every major power suspects someone is rewriting the sky.

The Missing Charter

The Sky’s Demand

Faction Conflict

Secrets

The atmosphere is not merely reacting to magic; it is learning from it.

Discovery · Ancient instruments in sealed observatories all point downward instead of toward the sky.

Impact · Nimb’s weather is generated by a vast living engine beneath the planet, and repeated magical damage is making it conscious.

The founders of the weather treaties still survive as scattered voices in the rain.

Discovery · Rain collected from unrelated regions contains the same unfamiliar memories.

Impact · The memories belong to the first weather-mages, who hid their minds inside the global water cycle to guide future generations.

The next great storm may transform Nimb’s climate permanently.

Discovery · The Blue Choir’s oldest hymns match patterns found in storm movements.

Impact · The cult may be correct that the coming storm is a planetary birth rather than a natural disaster.
