Balance

Eugene Donner is a sixteen year old Human, a minority race in the massive empire of the King's Domain. On a trip to the capital of the kingdom to visit his dying grandmother, Eugene is noticed by a military official and finds himself dragged to the palace. Because of a genetic mutation, Eugene is the only Human with an energy core--an organ that gives every other race the ability to wield energy, a phenomenon of magic--and the monarchy of the King's Domain send Eugene out on a mission. Grow stronger, and he will become the greatest weapon for them to use in their civil war.

The only problem is, the Resistance--a militia group fighting the King's Domain within the empire--is after Eugene and want him dead. Eugene finds himself falling into a political mess he doesn't understand, and finds his life in danger every day for the orders of a king.
