The world of NullFold

The world is a tower of seven stacked worlds. Between them lie fold membranes that only the next pickaxe tier can break – dig down at the same X/Z and the next world begins.

Sky Realm
Floating cloud reefs, rare sky flora and updraft columns. Reached through the cloud membrane.
