Heir of Wilberforce

The seven worlds have been a place of war and carnage for hundreds of years. The strong enslave the weak and take over their world just to have some extra space. A race of demi-humans takes over the priceless first world for years. The humans grow tired of living in the lower worlds and challenge the demi-humans to war. Armad is an innocent bystander from the third world whose village is engulfed by the war. He doesn't care about ambitious humans or greedy demi-humans. All he wants is to save his dying mother. Will he be left alone to cater to his mother, or will the universe be cruel enough to stand against him?
