If you join a camp, you will be able to visit everyone else's manors in that camp. You can also request an invitation for a manor visit; try shouting in WORLD chat and other players can invite you for a tour. (You can 1 hour access if invited)
So there is no zone to visit? How do I leave messages at the manor if I can鈥檛 get to it? Also how do I raid also if I can鈥檛 get to another players manor?
