In the beginning, it was difficult, but over time, it became the norm. Kayden was always behind major events and wars. The government-funded both sides and as soon as one side lost, it was completely eradicated, allowing new people to take over the city. Kayden had devised a system where the same group of people couldn't control two cities, preventing monopolies and forcing new individuals to rise and become powerful.
When a city lost a war, it was given 1 to 2 centuries to recover. Moreover, the government and other cities would help rebuild, forming new circles of alliances. The cities were divided into levels of power, starting at level one for the weakest and going up to level five for the strongest. A city's level was directly proportional to the number of wars it had won, and its resources were distributed based on this level.
