Niflheim
Book 1: Dark Warrior Rising

Orivon Firefist was captured as a six-year-old child by the Nilfghar - the dark elves - who attacked his village by night on one of their surface raids. Fifteen years later, he is a moon-pale, scarred, muscular giant of a man, who has spent his days at forgework for a dark elf family. He has been trained by the beautiful Tsarnarra, a lash-wielding matron who is icily cruel, but proud of the slaves that she has trained. He longs to return to the surface world, even if that means destroying the entire dark elf empire along the way!
