Currently the way i get it if a tribe setup the villiage and town in a area they cant just abanndon everything and move the totem.

What happends if the world expands and a tribe want to move, at that point they'll have to disband the totem and reinvite all the members again.

Doing that with 5-6 members is fine but it could start to become a pain with 20-30 people having to be at the same location at the same time.

I mean the indians didnt close down their tribe just because they moved around, they moved as a tribe.
