After the dark ages, when everything that powered the world mysteriously crashed, a nomadic tribe introduced a crystal called "Sinvin", becoming man''''s salvation. Its magical properties reinvented the world and how things worked. This began the Elementa Age but also a future of brutal domination by those who used Sinvin.
