During the game, someone will case the area on another pretext to determine the location for sure. Then Orion, Pyxis, and Canis- maybe Lacerta and Cepheus, too, depending- will cause a distraction while Scowl, cloaked so that King can't spot him, takes it and runs. Even if it's the ceiling, he should be able to reach- those shoes he wears let him jump to heights that simulate flying, and they grant him the speed to clear the area quickly afterward, too.
