Plot Synopsis

A few brave men and women banished the gods to the realm of the unconscious -- a place they called the Underworld -- but one of these young men, Hero, gradually transforms into a ruthless leader of men -- and a match for the gods themselves -- following his dramatic experiences of betrayal, love, disappointment, empowerment and exile. Hero, the bastard son of King Aegeus, is the holder of the Lexicon, the secret code that allows man to enter Olympus. In a sense, Hero is the gods' "canary in the coal mine": If he -- or any other human for that matter -- knocks at Olympus' door, Zeus knows that Man has exceeded his status and is on the verge of becoming a threat. Hero's destiny has been prophesized, and Oracle can help him. On the outside, Oracle is an unaffected, straight-forward and trustworthy Seer, the mouthpiece of the gods, but her visions, with their terrifying truths and destined events over which she is helpless, haven taken their toll over the years. But Medea, who seeks the Lexicon, is working against therm. She's charismatic, she's ruthless, she's sexy, she's magical -- and she even married Aegeus just to get the Lexicon and the power that comes with it. Groomed to rule, Aegeus always believed he held the key to the Lexicon, but upon having a son, the Lexicon left Aegeus for his first born, causing him to lose some of his luster -- and officially tipped his ratio of speaking to screaming in favor of the latter. Now, this mythological drama series tells the story of one man's journey towards his destiny, which could end the whole world.
