When the Golden Tribe invited other races to join them among the stars, three sentient races answered their call. The Golden ones called them the Bronze, Silver and Heroic Tribes. Just before the Golden Tribe left to travel to another universe, a fourth race appeared, travelling to the stars on their own accomplishments. The Golden ones named the human race the Iron Tribe. As time passes, humanity suffers at the hands of the more dominant races and is now facing extinction.

Following a prophecy left by the Golden Tribe, Princess Dhianeira sets out to search for the powerful being that might be able to save humankind, finding a wild-haired boy named Age on an abandoned planet — a fateful encounter that will not only determine the future of humanity, but also the fate of the universe.
