The "introduction" adventure to 5e, Lost Mines of Phandelver, gives us a fairly basic "little town in Faerun" to set the story in. This is the synopsis of the town and its history according to the internet. This is setting up the expectation to someone new to D&D what the world is like they are adventuring in.Well my experience must be different.
Because I've dealt with chains of ruling nobles/knights/priests/mages/druids/officials created by many DMs. And these chains of power are what keep the commonfolk safe when the adventurers aren't there. The adventurers in turn may jump into dungeons and die. However should they survive, the political and military powers give them quests of many colors. There were swords and spears everywhere. A quest was when for one reason or another, some local power could not send their own men.
I've typically only seen single independent small towns in the wilderness, as colonies, or heavily fortified with muscle, magic, or money. Or in points of light like settings when organization that level is near impossible.
So if the PCs looked up, there was always someone bigger looking down until very high levels
Entry for Phandalin
Phandalin was originally a farming community. However, when the orc of the realm of Uruth Ukrypt had destroyed all game in their realm, they went in search of food and turned on the human settlements in the area, raiding them. Phandalin was one of these settlements, and in 951 DR, it was overrun and then abandoned.
After Volothamp Geddarm passed through the town and wrote about it, the area experienced an influx of tourists and adventurers.
Sometime in the 1400s DR, settlers from Neverwinter and Waterdeep resettled the ruins of Phandalin, and it was well-established by 1491 DR.
In the 15th century DR, a group of bandits known as the Redbrands, or the Redbrand Ruffians, settled in Phandalin, and made their lair under Tresendar Manor. They committed several terrible acts, such as racketing local businesses, kidnapping over a dozen travellers and selling them into slavery, killing the woodcarver, Thel Dendrar, for his defiance, and later kidnapping his family.
Phandalin had no functioning government, but the townsfolk annually elected a "townsmaster". The townsmaster would serve as a judge and mediator, and also kept the records that needed to be kept.
End
-There are no defensive works despite being in the "monster ravaged" areas of the Sword Coast.
-In the entire history of the town there have been two major security issues...a TPK from orcs and some bandits that have killed one townsperson and kidnapped their family.
-They have no protection from some far away nobility.
-There is no "baron", "duke", "lord", "king" or any other sort of nobility responsible for the town.
-They have no apparent ties to other towns/cities other than as trading partners.
This is how 5e sees a small town. If you picture your small towns being something different than this, that's fine, but you are picturing something other than the 5e baseline that the starter set is laying down.
