For thousands of years, the Torathians and the Solturians have killed one another in the name of their respective Gods, even though neither religion has proof that either God actually exists. Until the day that both Gods appear in the sky, battling each other to the death, and nearly destroying the world as a result. Twenty years later, society has begun to rebuild from the mass destruction decades earlier. The bones of the Gods have been scattered across the planet and contain incredible power, and thus are highly desired but difficult to find. Sixteen year old Esper Haddon just wants to live a normal life but when she discovers a bone while working on her family farm, dark forces become aware of the discovery, and nothing will ever be the same for her.
