There was once a people who called themselves the "Golden Tribe" who possessed many powers, including creating planets and seeing into the future. They then called on primitave beings, telling them to explore the universe. Three races were able to reply to their call; "Silver Tribe" the "Bronze Tribe", and the "Hero Tribe". Long after, when the Golden Tribe were about to move on to another universe, a new race replied to their call. This new race, humankind, was referred to as the "Iron Tribe".

Now the Iron Tribe is on the verge of extinction, when they are finally able to discover the Ruined Planet of “Oron”, the planet that holds the man who will become their saviour. They reach the planet only to find a boy that calls himself Age, but soon after this they are suddenly attacked by the Bronze Tribe.
