The darkness that comes before - R. Scott Bakker

A score of centuries has passed since the First Apocalypse. The No-God has been vanquished and the thoughts of men have turned, inevitably, to more worldly concerns

Drusas Achamian, tormented by 2,000 year old nightmares, is a sorcerer and a spy, constantly seeking news of an ancient enemy that few believe still exists. Ikurei Conphas, nephew to the Nansur Emperor, is the Exalt-General of the Imperial Army and a military genius. He plots to conquer the known world for his Emperor and dreams of the throne for himself. Maithanet, mysterious and charismatic, is spiritual leader of the Thousand Temples. He seeks a Holy War to cleanse the land of the infidel. Cnair, Chieftain of the Utemot, is a Scylvendi barbarian. Rejected by his people, he seeks vengeance against the former slave who slew his father, and disgraced him in the eyes of his tribe.
Into this world steps Anasrimbor Kellhus, the product of two thousand years of breeding and a lifetime of training in the ways of thought, limb, and face. Steering souls through the subtleties of word and expression, he slowly binds all - man and woman, emperor and slave - to his own mysterious ends. But the fate of men - even great men - means little when the world itself may soon be torn asunder. Behind the politics, beneath the imperialist expansion, amongst the religious fervour, a dark and ancient evil is reawakening. After two thousand years, the No-God is returning. The Second Apocalypse is nigh. And one cannot raise walls against what has been forgotten
