I just had an epiphany. Hercules in the myths guards the gates to Olympus. So does that mean he is the guard at the front desk in the Empire State Building? He would then be technically guarding Olympus and he knows about the gods, in "... The Lightning Thief" he says "No appointment, no audience, kiddo. Lord Zeus doesn't see anyone unannounced." I think I will post a story talking about some of my opinions and ideas from the story and probably discuss this.
