In the year 2016, our once peaceful world was thrown into chaos when a dream shifter materialized his violently catastrophic dreams into reality. A secretive organization bet on saving these extraordinary beings from their own torment found the vulnerable dream shifter, and sealed his power into a necklace. To prevent any further harm, the dream shifter set out to help the survivors of the catastrophe rebuild a new civilization upon the only land mass left; an island created by his dream… Ararat Island. Once the exodus to Ararat Island had settled, he set off on a journey, never to be seen again. Five hundred years later, a girl fated to have the same ability is born.

For the girl's 16th birthday, she is gifted a necklace found on the shores of Ararat Island… the very necklace that holds the power to end the world. While she slept that evening, sentience besets a dream manifestation that has become obsessed with his creator. He shatters the necklace, knowing that if she stays… she'll be his, forever. Fantasies from her dreams manifest into reality the moment the necklace shatters. The real and dream worlds become one, and she is consumed by the very dream world she created. With the remaining, shattered fragments of the necklace causing chaos throughout the world, powerful Heroes with special skills are called upon to help save it.
