[Sweet, a map. But...crayon? A child? Was there a child here...?

Looks like they're on the personal floor, maybe? He didn't see anything throne-like or engine-like, and the other floors are familiar. Rocket legs....maybe the base is mobile?

Is this on paper or fabric or something else we can pick up and take with us, if so. Nagisa's now. Is there anything else in here? Are the screens on all sides or is there an obvious back of the room to check? Gotta be more here.]
