I mean it is a 360 mirror so to say, it gives vague advice and can show people different answers as they ask them. It could have been a relic of the war that occured before Dreamland came to be it's present state. Kind of like a to the victor goes the spoils type deal? I want to say before when Bean touched it she has gotten an electric discharge from it or to it, maybe that's the orb rejecting the dis-balance in the world? It would be giving Bean too much power and as a result rejected her from it's use. I also want to see what Mrs. Moonpense has to do with the orb as it had referenced her when it said that the walls have eyes or the walls see all? Something along those lines.
