The Duality Duke

Shade is perfectly happy with his role as the sword-crazy spare heir. His older sister Pru is a perfect diplomat, and much more suited to support the throne as the crown princess. Shade is fine with being thrown into the upcoming combat, as the year of the Century War is finally upon them. It's almost been his only purpose in life to lead his people on a global spanning battlefield. Everything is right in Shade's world until a year before the war is set to begin he's instructed by his father to play the villain and kidnap a clairvoyant Ascerian princess who turns his world upside down.
