In the land of Szerika, there lives a society of people who live peacefully. There are no other groups of people anywhere nearby, so the Szerikans have no worries of war. They do, however, fear dragons.
In Szerika, dragons appear for raids on settlements about once every year. The Szerikans have no defenses, and indeed have chosen to not fight the dragons, in keeping with their practice of nonviolence. The dragons are, after all, far too powerful against the medieval technology the people have.
As an alternative, the Szerikans have chosen to create movable cities. There may be other alternatives to fending off dragons, but these ones are pretty powerful.
The chosen method for moving the city is modular building. The thing is, it's hard to build buildings and floors of buildings that can be attached together, moved a few dozen miles, and re-assembled - all with medieval technology.
Is this possible?
Here are some specifics:
- The city has a population of about 5000 people, with perhaps 750 buildings.
- No buildings are higher than three stories. Most are houses and businesses, built mainly with wood.
- The construction/assembly materials available are those found in the Middle Ages.
- The people need to move about ten miles in one week.
