Castle

The Castle is the spine of all progression: it caps the level of every other building, unlocks new structures as it grows, and its upgrades demand ever more of every resource. Castle art changes as it levels, so a kingdom's strength can be read at a glance from the world map.

Available from the start

The castle at every stage

Level tables

Cost and time are for the upgrade leaving that level. Level 30 is the cap.
