Major character who has only appeared on 1 page in the entire OOTS saga

[DapperWarlock]

I can't remember if anyone else brought up this idea earlier, but as long as we're bringing up misdirections, I just noticed that the hint didn't specify who this character will be allied with. If there's any misdirection here, I'd put my money on the idea that the character Rich is hinting at will actually be an ally of someone else like Serini or Team Evil or one of the six other sides of the Gate conflict.

Not that I really think that'll be the case... just an interesting idea.
