The spawn is in front of the first sand village. The village got a couple of houses and a few farms. To get to the other two villages turn to your left and walk or fly in that direction for 1-3 minutes and you will get to the two other villages. They aren’t a double village but they are just 20-30 blocks apart so they aren’t hard to find.
Neither of the villages got any blacksmiths but they provide great shelter and food resources for starting out in a new survival world. The farms got enough vegetables to survive for many nights ahead and the houses provide some comfort for surviving the night. And let’s not forget about the villagers who can be nice to chat with, even if their language is hard to understand.
