The Prince of Nothing is a series of three fantasy novels by the Canadian author R. Scott Bakker, first published in 2004, part of a wider series known as "The Second Apocalypse". This trilogy details the emergence of Anasûrimbor Kellhus, a brilliant monastic warrior, as he takes control of a holy war and the hearts and minds of its leaders. Kellhus exhibits incredible powers of prediction and persuasion, which are derived from deep knowledge of rationality, cognitive biases, and causality, as discovered by the Dûnyain, a secret monastic sect. As Kellhus goes from military leader to divine prophet, Drusas Achamian, the sorcerer who mentored Kellhus, comes to realize that his student may well be the harbinger of the Second Apocalypse.
