:the great room:

You enter a perfectly round room with tastefully eccentric art floating throughout the air. You accidentally nudge one piece, and it slips into the fourth(?) dimension, only to reappear on the other side of the room. “Oh, don’t worry about that! This room is highly experimental so it’s constantly being rearranged.” Please, feel free to explore! What’s mine is yours - except that which is mine, of course.

“who are you?” “what do you do here?”
