Sworn to preserve intergalactic order, the Iron Knight Corps has existed for centuries. Its newest recruit, Charles Grove, is the first human to join the ranks. The Iron Knights have little regard for humans, who have thus far been unable to harness the powers of the being core each member has. But Grove, a gifted and cocky high school student, may be the corps' only hope when a new enemy called Glissedon threatens the universal balance of power.
