To win The Great Siege, you must lay siege to pre-spawned NPC "districts" and defend them for a set amount of time, in order to accumulate Influence Points to win the world. The large city in the center is split into 4 boroughs, which consist of 9 districts (villages). Districts always have 1 loyalty, and take the exact same time to reach no matter where you attack from. They also have a defense penalty that makes defending them harder and encourages player interaction.
