The country of Ayphon has been seeking the final words to a dire prophecy for many years. When Dark learns that his mother has those words in her possession, he is shocked. He is even more astounded when he learns that he and his twin sister, Light, are to be his country's saviors. Forewarning of a sinister evil, the prophecy urges them to begin a journey to defeat an unknown foe. When a horrible fate befalls their village, the two are marked with their call of destiny. They have no choice but to set off in quest of an army that will stand by them, marching into the thick of battle even though it could mean their lives. If this unlikely bunch of warriors cannot defeat this foe, their country will be the first of many to fall.
