Spawned in newly abandoned town

How is exactly the programs work for us to spawned in newly abandoned town?

I think it just has to do with spawn points. Someone build a town on top or close to a spawn point, and everyone died and left the town abandoned until someone spawned there again.

The map is huge from what I understand, so there has to be a lot of spawn points, and I guess it depends on how many eves spawn to get you back to the town.

Don’t know if any of that makes sense.
