Spawn in by a Villagers worst nightmare

While sifting through hundreds of seed compilation videos I came across this. All on top of one hilltop, a woodland mansion, outpost and very unlucky village smack dab in the middle. Along with a washed up shipwreck completely out of water on a beach side, down below the mansion you’ll find 3 levels with a whole in the mid acting as a window allowing you to see down to the bottom. 1st platform you’ll find there are 3 villagers that got smart and built their houses down below, under that platform a the entire bottom side is covered with a hanging lush cave covering it and the walls exposing an ancient city below
