In the world of Erdas, there's a story of four noble animals who sacrificed everything to protect their homes from the ambitions of a mad king.

Briggan the Wolf, Uraza the Leopard, Jhi the Panda, and Essix the Falcon. Long before they were spirit animals, the four were still legends--Great Beasts, the most powerful beings to roam the wilds of Erdas.

Aided by a brave resistance of humans and animals, they gave their lives to protect the world from a threat more dangerous than any it had seen before: their own kind. Wise and cunning, gentle and ruthless, these are tales of the true heroes and villains in the war that started it all.
