"There is a saying on Gor that the laws of a city extend no further than its walls." "Outlaw of Gor" page 50
Maps
"It is illegal in many cities, incidentally, to take maps of the city out of the city. More than one fellow, too, has put himself in the quarries or on the bench of a galley for having been caught with such a map in his possession." "Magicians of Gor" page 388
Building
"I knew that only those who were free would be permitted to make a city. Doubtless there were many slaves in Ko-ro-ba but they would be allowed only to serve those who raised the walls and towers. Not one stone could be placed in either way or tower by a man or woman who was not free. The only city I know of on Gor which was built by the labor of slaves, beneath the lash of Masters, is Port Kar which lies in the delta of the Vosk." "Assassins of Gor" page 60
Entrance
"As was wise I avoided cities in my long journey, though I passed several, for to enter a city without permission or without satisfactory reason is tantamount to a capital crime, and the punishment is usually a swift and brutal impalement. Pikes on the walls of Gorean cities are often surmounted with the remains of unwelcome guests." "Outlaw of Gor" page 49 "As we do have the yellow ostraka and our permits do not permit us to remain in the city after dark," said Marcus, "I think we should venture now to the sun gate." Marcus was the sort of fellow who was concerned about such things, being arrested, impaled, and such."

"Kurrus, of the Caste of Assassins, entered the great gate of Ar. Guardsmen did not detain him, for he wore on his forehead the mark of the black dagger." "Assassin of Gor" page 6 "When he of the Caste of Assassins has been paid his gold and has received his charge he affixes on his forehead that sign, and he may enter whatever city he pleases, and none may interfere with his work."
