Brethren turn to enemies, and enemies to allies. Constantine bows to Keket as he recalls his former self, but the faith of the mad priest conflicts with his loyalty to the queen. As the dark queen wreaks havoc aboard the Redeemer, the priest must choose between his queen and his God. Commander Drake and his champion Marcus quarrel like children. Unbeknownst to them both, the deal has turned sour, and calamity awaits at sea.

Chosen by the dark queen as her champion and tricked into accepting the task, Warlord Sasuke must defeat Drake to save his beloved Giselle. The fate of the realm shall be decided in the battle of wills between father and son. The victor takes all in the war for the realm.
