When magical relics are discovered in the stony canyons of Mercury Past, the village finds itself swarmed by the surrounding lands that seek the power of the lighted oracles. Recruiting children to war, the relics are kept safe by entrusting them to captains and sent out to sea. As the war begins to end, witches join the fray as they scramble to complete a sinister plot that will change the world in their favor. The only ones aware of this are a group of young spellcasters who desperately abandon the front lines in order to stop the witches. The children will have to travel to the many lands of their world. In their journey, they learn more of themselves through the origins of their own magic and follow the steps of fate that will propel them to their own destinies.
