Descent of Angels is the sixth volume in the Horus Heresy series of novels.
The planet of Caliban exists much as it has for thousands of years – the knightly orders protect the common people, fighting back the beasts that lurk in the depths of the seemingly endless forests. Young Zahariel and Nemiel aspire to join the greatest of the orders, led by the example of mighty Lion El'Jonson and his vision of a peaceful and unified world. But the coming of the Imperium brings new concerns and a new destiny for the Lion as part of the Great Crusade, and the sons of Caliban must decide if they will follow him to glory among the stars.
Descent of Angels is told from the point of view of planet Caliban native Zahariel El'Zurias, who begins the novel as an Aspirant of The Order (a monastic order of techno-barbarian Calibanite knights). The first half of the novel is set on Caliban and covers the final battles of The Order under the future Primarch of the Dark Angels Space Marine Legion, Lion El'Jonson. The book's second half describes Caliban's re-unification with the Imperium of Man as well as the actions of the Dark Angels Legion during the early years of the Great Crusade. Zahariel, selected as an Aspirant Space Marine, is ultimately accepted as a Neophyte of the Dark Angels Legion. A future schism within the Legion is intimated in this section of the book.
