Four children separated by vast distances all undergo the same ritual, watched by cloaked strangers. Four flashes of light erupt, and from them emerge the unmistakable shapes of incredible beasts - a wolf, a leopard, a panda, a falcon. Suddenly the p aths of these children - and the world - have been changed forever.
Enter the world of Erdas, where every child who comes of age must discover if they have a spirit animal, a rare bond between human and beast that bestows great powers to both. A dar k force has risen from distant and long-forgotten lands, and has begun an onslaught that will ravage the world. Now the fate of Erdas has fallen on the shoulders of four young strangers . . . and on you.
