Native villages are like Barbarian villages in many ways, but there are some key differences. The biggest is that they are peaceful so you can just walk over them. When this happens, the most likely thing the village will award you is 25 Gold. They may also give you a Caravan or Spy, but never Horsemen or Galleys, being peaceful. Like Barbarians, they may also show you other Barbarian villages or Artifacts. Artifacts are shown when they are near the village in question. The revealing of barbarian villages follows a similar behavior, but nearby artifacts are prioritized.
