Bizarrely, Canto Bight is the name of the city, not the planet that it's on. Yet Maz used the preposition "on." It's pretty shitty dialog, if you ask me. It should have been "in," not "on."MAZ: Oh yes, he can. You will find him with a red ploom flower on his lapel... rolling on a high stakes table... in the casino... on Canto Bight. POE: Canto Bight? - No, no. That's... Maz... Is there any way we can take care of this ourselves? MAZ: I'm sorry, kiddo. This is rarified cracking.
