Re: OOC2
That depends if you want to expand to a City base :)
City Base
Minimum Requirements are
city location
Land: Merchant House, Large Warehouse, Caravanserai and at least two Caravans
Water: Merchant House, Large Warehouse, Pier and at least one Trade or Merchant ship (Keeler or Sailing Barge).
If you need to buy a Keel Boat or a Sailing Barge from somewhere other than Midmarch - there will be a premium added to the price. In the same way as if you tried to build in Restov or Mivon.
