When an ancient dark force emerges from a centuries-long slumber, Conor, Abeke, Meilin, and Rollan must stop it from sweeping through Erdas and destroying their spirit animals--and the world.
A new threat -- something ancient and evil -- faces the world of Erdas and four young heroes and their spirit animals are determined to stop it as they embark on a desperate journey that takes them deep underground and to the far corners of the world.
