The story is centered around a young man named Rygart Arrow, a resident of a world where people can use "magic".

This magic is the ability to control and empower quartz, doing many things from creating light to operating machinery to riding giant mecha called "Golems".

Rygart, however, is one of the few exceptions; as an "un-sorcerer", he cannot utilize quartz, making many aspects of life difficult as well as being looked down upon by the rest of society.

Despite this, in his youth he managed to befriend Hodr and Sigyn, the future King and Queen of the Krisna Kingdom; and Zess, the younger brother of the Secretary of War of the Athens Commonwealth.
