This is the mercator village! The villagers who live here come from different places, bu they all share one common thing - trading. Each villager or village family has one trading topic. One of them has alchemy, while others sell what they harvest. The village has houses, made from stone and wood, and shops.
I used to have an NPC which sold all the kinds of potions, but my game crashed and I lost that progress. The build is not great, but I don’t really know how to build like the bakery above, I just know how to place blocks...
