[General RPG] So I just came upon this unreasonably small town

It has a Mayors house, Item shop, Inn, and Weapon/Armor shop. Each only has one person in it. There is also one empty house. That is it, no other people are in this town. As far as I can determine I am also the first visitor they have had in ages. How can this town even function like this?

It's probably less of an organized town and more of a glorified rest stop for travelling adventurers. The businesses there (items, weapons, and an inn) certainly seem catered to that crowd.

The inn was probably the first thing that was built, and the rest of the buildings sprang up to fulfill the needs of the sort of folk that tend to stop by.

The mayor's house probably functions as a general administrative/postal/news center, and they probably have food and supplies delivered at regular intervals from nearby farms or towns.

If it's seeming rather empty, it's probably cause the business moved away -- perhaps the dragons and princesses went further afield, and the adventurers moved with them. It happens.
