In War Kingdoms, players govern their kingdoms at the kingdom center. Kingdom center is the place where all economy, intelligence, military and defence buildings of a kingdom are found. Every kingdom has one kingdom center initially, and may own additional settlements (colonies and cities) through wars of conquest.
Center is the most critical place of a kingdom. In the game, it is not very possible for a kingdom with an undeveloped center to grow and become powerful. For this reason, kingdoms must keep their centers technologically well developed through unit and building upgrades. Villagers must also be populous enough to meet the requirements of the whole society.
Kingdom centers are not conquerable, but only plunderable. However, plundering a kingdom's center is sometimes more difficult than conquering a colony or city. The reason is that during a plunder war, the battle is affected by certain other factors such as the strength of the city wall. Such factors are inoperative in a war of conquest, because it consists purely of pitched battles.
