About
⚙️ Magitech Steam World ―― "The Age of Steam and Magic" The era is approximately the end of the 18th century.
Across the globe, coal-fired steam engines have begun to see practical use, while simultaneously, ancient magical arts have undergone significant evolution.
Magic is no longer the province of myths or a handful of sorcerers; it has been integrated into daily life and military applications.
People call this era the "Age of Steam and Magic."
🔮 Magic Magic is studied as an academic discipline, not just a matter of innate talent.
Mages study at royal academies and universities, combining magic with mathematics, physics, and alchemy to create new spells.
⚙️ Magitech Machinery Technology that combines steam engines with magic.
🏙️ Cities Stone-paved streetscapes characteristic of the 18th century remain. Horse-drawn carriages, steam automobiles, and magitech vehicles traverse these streets.
Streetlights utilize magic stones, illuminating the town with a pale blue light at night.
In factories, massive steam engines operate, surrounded by glowing magic circles.
🚂 Transportation Magitech railways connecting major cities have only just begun construction.
Meanwhile, massive magitech airships are used for long-distance travel. These airships are equipped with magical buoyancy control devices, achieving aerial navigation impossible through pure steam technology alone.
👑 Society Social systems remain very much like the 18th century. ・Nobility Control politics, the military, and land.
・Mages Hold very high social status. Royal mages and archmages, in particular, wield great power.
・Merchants and Capitalists Owners of factories, mines, and magic stone mines, emerging as a new power class.
・Engineers A new profession specializing in the research of steam engines and magitech machinery.
・Laborers The majority of the population, working in factories and mines.

It excels in magitech ship and airship technology; the royal capital Astoria is dominated by a massive port and the Royal Academy of Magic.
❄️ Kingdom of Nord — Capital: Valgren An ancient kingdom possessing the northern snowfields and mountain ranges.

The capital Valgren is a massive fortress city where the royal palace and mage towers overlook the town.
⚙️ Germania Empire — Capital: Eisenburg A massive industrial empire ruling the eastern continent. It has rapidly developed steam engines backed by coal and iron ore, mass-producing firearms and magitech weaponry. The capital Eisenburg is the empire's largest industrial city, lined with chimneys and factories.
🌑 Southern Uncharted Region A vast area beyond the control of any nation. It is an unknown land of giant forests, deserts, monster dens, and ancient ruins, frequented by adventurers and explorers.

Sourcebook
Intro
―― The Age of Steam and Magic ――
A world where magic is a common reality, and steam engines have merged with magitech. On the continent, three great nations exist: the maritime Kingdom of Albion in the west, the snowy Kingdom of Nord in the north, and the industrial Germania Empire in the east.
While the three nations vie for supremacy, a vast uncharted region, largely untouched by human hands, stretches across the southern part of the continent. There, ruins remain of a mysterious civilization said to have flourished in the distant past.
Who that civilization was, why it perished, and what it left behind—nothing is known for certain today. However, legends persist of a massive castle that still floats in the sky amidst the southern sea of clouds.
Some believed, others did not, but those who did called it 'Caelus, the Castle in the Sky'.
