Protectorate

A large zone that consists of dozens of neighboring provinces that share the same “green” game mechanics and limitations. There is no PvP possible on the territory of protectorates. Only here can players build personal claims and these claims have a "forcefield" that will bump everyone out of the claim who is not allowed to enter the personal claim. Guilds cannot build their monuments and outposts on protectorate land, though they can capture the provinces of the protectorate in order to collect taxes from these areas.
