For better understanding, all structures were divided between:
- natural — those already built or simply present in the nature; the monarch may interact with them, but won't build them. E.g.: architecture shrine, hermit cottage, portals, ruins, signpost, statues, trees and vagrant camps; and
- buildable — those built or rebuilt by the monarch. E.g.: boat, catapults, farms, teleportation portal, towers, town center and walls.
