Olympia: The Age of Gods PBEM (Oct 4 2000)
A sublocation appears inside a province. Sublocations are shown in the turn report this way:
Inner locations: Yew grove [em28], 1 day
Sublocations include inns, temples, guilds, and ships as well as bogs, caves, graveyards and other natural features. (The only places in Olympia that aren't sublocations are provinces, cities and mines.)
The owner of a sublocation is the first noble in the sublocation. The owner of a sublocation controls who is permitted to enter, and what they will be charged (if anything) to enter.
