Can Gold use telekinesis on your character? Sure thing!
Can Gold use curses on your character? Probably, but I'd rather you ask first.
Can Gold "disheart" your character? Probably not, but if it comes up for some reason, maybe!
Can Gold make bargains with your character? Ooooh. Cabal's had bad experiences with making that sort of deal, but he can certainly try. If for whatever reason he has something Cabal needs bad enough, it could happen. Cabal will try to find a way to screw him over, though.
