A long time ago, Mara the Intergalactic Devourer tried to gain access to the planet Heartsong through an interdimensional portal. His growing power awakened the galaxy’s four Guardian Spirits. They narrowly defeated Mara in what is now called The First Great Battle. They managed to take control of Mara’s portal, a great source of power and information. To ensure Heartsong’s continued protection, the Guardian Spirits shared their powers with a special person, calling him the first Great Hero.
Since that time, every generation has had a Great Hero. Their power awakens early and is instinctive. Whenever the Hero senses a threat, he calls upon White Tiger, Black Turtle, Green Dragon and Red Phoenix to help him defeat it.
