Betrayed from within and overwhelmed by dark sorcery, the valiant armies of Pars are overrun by the warrior-fanatics of Lusitania. Escaping the destruction of his homeland, the heroic Prince Arslan begins to assemble a group of five, extraordinary allies—a priestess, an exiled warrior, a mischievous minstrel, an insightful artist and his attendant—to aid him in his fight against the Lusitanian invaders. Together, they must build an army and defeat 300,000 trained soldiers—including the mysterious Lord Silver Mask who has also laid claim to the throne of Pars.
