For the most part, it has been more mirrors - more remains of what might have been restaurants or lounges, if one were inclined to call the overly mirrored furniture 'remains.' (Given the mirrors being so clearly unnatural, Eula is inclined to.)

However, there is still an access door leading, presumably, further upwards - there's one more floor above them, if the windows on the outside are any guide.

Eula hms and tries the door, which has no handle nor any evidence of one being removed, with a gentle push. It doesn't give. "It seems we shall have to bust in," they say. "I don't suppose you have anything other than muscle to make the job easier?"
