Krakia?

No, it doesn't. It's an explicitly foreground object. That's exactly as big as it is.
Now if you were talking about this...

regardless, these are at best single space living/working facilities , not worlds within a world. i'm convinced that "meshing" that has been pointed out is at most a shield to hide krakia (since it's high tech this is well within the realm of possibilty) but more likely it's smoke streams from vehicles or light patterns.
