The Nightlands, the dark, cold world of demons and monsters, is ruled by seven demon princes. A nameless human, slave to one of these demon princes, lives a life of misery and torment. Haunted by the few happy memories of his past and plagued by a daily existence of pain and fear, he struggles to maintain his sanity and dreams of revenge upon his tormentors. When another of the demon princes provides him with a strange power, he sheds his life as a slave, takes up a new name, and becomes a weapon. Elsewhere in The Nightlands, the young lightwielder, Temin, begins his own quest alongside the powerful and frightening Ducahn.
