Core Systems
Progression
Kingdom progression reflects growth, organisation, and long-term investment. As a kingdom develops, it unlocks upgrades that expand its capabilities, strengthen its members, and reinforce its presence in the world. Progression is collective; contributions from all members support shared advancement.
Most upgrades require two things: an emerald investment through the Treasury, and the completion of one or more Foundation buildings. Emeralds fund the advancement while Foundation buildings represent the kingdom's physical development and infrastructure. Together they determine what a kingdom can unlock and how quickly it progresses.
Upgrades can be browsed in-game through /k upgrades.
