what if it was a giant city of all marble and cobble paths with about 50 different buildings that are about 20 x 20 and there are residents here but they are rare and assigned to one house that one house could have a sign like "random citizen jo lives here" if you found these new villagers they would trade for almost anything and there trades wouldn't be crap or require emeralds instead more like iron gold redstone lapis occasionally diamonds and very rarely emeralds. also they could trade a new ore or there could be a new ore what would that ore be?

It can be a Sky Dimension!
