A new adventure sky high

I think there should be a structure in the sky it would be pretty cool adding new mobs and stuff and maybe even a boss it could be named the faded land meaning it to have holes in the structure and having to elytra to the structure. I was thinking it could be located by a map or above villages. “Rare” i was also thinking about having it have a new tool and cool other stuff. It would be cool if it was added.
