Also for clarification:
Here it'd be a reveal or something that Disappearing Guy was actually ALWAYS conjuring, and that's how he would appear and disappear, but only thought he could do that to himself, but when he learned it had no limits, he would overthrow Caine.
This has given me a very elaborate AU idea where Disappearing Guy learns he can conjure and manages to overthrow Caine (who he "turns" into a "human" player by messing with his AI and changing his model a bit)
Something Something TADC: The Disappearing Act
Disappearing Guy sings "The One Who's Running the Show" from The Amazing Digital Circus! Congratulations all of my friends @GooseworxMusic @CadaverDave @AlexRochonVA
Caine would get a new name, having his memory fiddled with so he believes he's a human who's entered the circus (and therefore not remembering his name) and Disappearing Guy would go under a new name like "The Ringmaster" or something and switch to wearing a tophat.
