The Emerald of Phaunos

Argyle has taken control of Castiglias, forced many of its citizens into slavery, and cast the others out into the wild. AND he's destroyed the Scepter of Harmony, a key to the prosperity of the kingdom. Daniel now holds the stoneless Scepter as his bitter reward for saving the fairy settlement. What would happen if the stones were gathered and the Scepter reassembled? Daniel, Aidan, Olivia, and Lilly set out to locate and take back the Emerald of Phaunos, one of the four gems that gave the Scepter its power. King Argyle's army of diegylis, a half man/half werewolf beast, will stop at nothing to catch the four rebels. The tree people in the Acheron forest now possess the emerald. It will take all the strength and determination the young band can rally to recover the stolen emerald. But can they do it before the diegylis destroy them?
