This drama series looks at the world of humans, gods and monsters in mythological times. The story begins during a time when the gods have been banished to the underworld. Hero, a brave young man and bastard son of arrogant King Aegeus, embarks on a journey to find out the truth about his past. What he doesn't know -- at least initially -- is that he inherited from his father the Lexicon, the secret code that allows man to enter Olympus, and that his journey will eventually reveal his destiny and, potentially, the future of mankind. Over the course of his journey, Hero transforms from a fresh-faced young man into a ruthless leader of men.
