The war is threatening to break out again in the Holy Land. The Christians, led by Gregory of Arcos and the anxious Duke of Taranto, are preparing to win over Jerusalem and to tear it up in the hands of Sultan Ab'dul Razim. The preux Gauthier of Flanders opposes this new campaign which he considers to be a madness. All ignore it but, in the shadow, acts the Qua'dj, a demon determined to reap his harvest of warrior souls. Faced with his dark designs, Gauthier and the captivating, but fearsome, Syria d'Arcos will soon rise up.
