Conor, Abeke, Meilin, and Rollan are prisoners. Framed for a crime they didn't commit, the four young Greencloaks have been captured by the ruthless Oathbound. They discover that the plot against them runs deeper-and is far more sinister-than anyone realised. To stop this conspiracy, the Heroes of Erdas will need absolute faith in their spirit animals. If they fail, all of Erdas will drown.
