Boundaries (city lot size) are region specific.
- (This means that you may have a different sized city lot in each region)
Currency used to pay for boundary expansions are region specific.
- (Mainland uses Silver Currency while the Water Colonies use Sand Dollars)
You may purchase boundary expansions in only one region at a time.
Boundary expansions are immediate providing you meet all the requirements for expanding and you purchase the boundary expansion.
Boundary expansion requirements are tied to total number of allies you have recruited and the amount of currency needed to purchase the expansion.
