The Corean Chronicles: Books 1-3 by L. E. Modesitt Jr. (HC/DJ)
Legacies — Alusius is drafted into the local Militia to fight against the invading slave armies of The Matrial, an immortal ruler in a nearby land. If the evil surrounding The Matrial is not brought to an end, the world as he knows it could very well end.
Darknesses — Captain Alusius faces new challenges, both military and magical. A would-be conqueror has revived sorcerous creatures of legend to assist in his crusade to reunite the continent under his rule. Alucius's Talent is the only hope against this foe, or even survival.
Scepters — Alusius must quell a strange religiously-inspired rebellion and then find a way to destroy the powerful weapons of ancient design. When a different, covert enemy threatens, only the timely assistance of the ancient Soarers, and the addition of his wife Wendra's Talent, gives him any hope of success.
