"I have yet to mention our jailor. It is the devil Phelot, the shade who decimated Avon's Grove during the Great War. It is a wonder he has not yet sought vengeance upon us, as he was sorely injured by The Deceiver upon our arrival."
-Myth II, Level 20, "A Murder of Crows"
Obviously you can infer, from this passage, the Journalist from Myth II is either a berserk or one of the heron guard. I doubt he'd be an archer, the accent is too different.
I'd almost bet he's a berserk. Though when he does speak in this journal, you can notice his voice is calm - and most people of this accent don't have the funny high pitch to their words as in comparison to when they're yelling.
I may be wrong, but I'd say theres a 75% chance he's a berserk.
