“Page 6 - The GridThe board is largely empty as the world is mostly unknown to you. “The grid” refers to any location that is connected to the starting Havens (i.e., a path can be traced along supply lines and/or sea lanes to the starting Havens). “
Whilst technically the starting Havens are connected to the starting Havens, the count is specifically for Cities and Havens don’t count as Cities.
So revealed Cities don’t count until you connect them by a line.
