Olympia: The Age of Gods PBEM (May 4 1999)
The owner of a building, ship or other "small location" is the first noble in that location. Places that can be controlled in this way include inns, temples, guilds, mines, and ships as well as bogs, caves, graveyards and other natural features. These kinds of small locations are called sublocations, since they appear inside a province or other location. The only places in Olympia that aren't controlled this way are provinces and cities, which are large enough to require the full-time presence of a garrison to control (see below).
The owner of a sublocation controls who is permitted to enter, and what they will be charged (if anything) to enter.
