I DID NOT GUESS THAT EMPEROR HAKAN WAS ACTUALLY BELIAL.
To be honest, I didn't think Belial would even bother to disguise himself at all, since it was pretty obvious he already had total control of Caldeum. I thought he was just chilling inside the palace, or maybe lurking somewhere in the ridiculously huge sewer system (seriously, how does a city of thirty people produce that much poop?) and that my character would confront him there.
If I had any suspicions, I was always able to explain them away. Why do all of Emperor Hakan's lines sound so stilted and forced? He's probably being voiced by an inexperienced child actor. Why is he able to appear anywhere in a puff of green smoke? Well...this is a fantasy story, right? Maybe he has a little Witch Doctor blood in him.
So, am I beyond help? Should I spend a few weeks watching Scooby-Doo in an attempt to build up my skepticism to healthy levels? Does anyone sympathize with my plight?
