The sun sets on the land of Valisthea.
For centuries, people have flocked to its mother crystals to partake of their blessing, the abundant ether that fuels the magicks they rely on in their daily lives.
But as the ether begins to fade and the lifeless deadlands spread wider and wider, the fight for the final flickers of the mothers' light grows fiercer and fiercer.
A bloody battle rages across the kingdom, as rival nations send their ultimate weapons against each other: the Dominants.
The men and women within whom the revolutionary power of an Eikon sleeps. There are few in Valisthea whose lives have not been touched by this war for the blessing of the crystals, and Clive Rosfield, firstborn son of the Archduke of Rosaria, is no exception.
Unlike most, however, the twists and turns of fate are to reveal to him the dark truth that lies at the heart of his world, and lead him on a mission to destroy these very mother crystals that the rest of the realm holds sacred.
The legacy of crystals has shaped the destiny of humanity for quite a long time.
