hmm well i have this crazy where a specific location (country) will be occupied by a specific guild (Preferably the strong ones). Other guild members may not be able to set foot on that location and attack the people in them unless they are declaring war. So its like a stronghold or a fortress or a hideout or whatever you wanna call it. However obviously trade fleet are allowed to go to this Islands.
Well its crazy but what the hell.
P.S not sure where the best place to post this so i put it on two separate place lol
