The World City
Monorepos, from strategic choice to technical arcana
At the end of a road crossing three kingdoms stands the World City, a metropolis so vast it has its own seasons. Thousands of craftspeople work in the same interconnected workshop: smiths, weavers, alchemists, scribes, all under the same titanic roof. The halls stretch for leagues, the archives fill entire floors, and yet everything is connected, everything is coherent.
The City Architect greets you atop the central tower. From there, you can see the immensity of the workshop below.
« Every village has its forge, its library, its temple. It is simple. It is autonomous. But when a thousand craftspeople must work together, share their tools, reuse their creations, a single giant workshop sometimes becomes more efficient than a thousand separate ones. That is the choice the greatest cities of the world have made. And it is a choice with a price. »
The World City quest unfolds in two parts: first understand the strategic choice, then descend into the technical arcana.
