The Chronicles of Uriel Ventris

Newly promoted to the captaincy of the Ultramarines Fourth Company, Uriel Ventris leads his warriors to the world of Pavonis, where vicious alien raiders are bringing death and destruction. As Pavonis descends into political turmoil, Uriel and his warriors must battle the xenos as they unravel a plot to unleash an ancient evil buried deep beneath the world - the mysterious and deadly Nightbringer. 

The Great Devourer is descending on the world of Tarsis Ultra, but to defeat the xenos horrors, Captain Uriel Ventris may have to embark upon a dangerous and unorthodox mission. 

Exiled from the Ultramarines Chapter by Marneus Calgar, Captain Uriel Ventris ventures deep into the dreaded Eye of Terror to atone for his disgrace. There, Uriel must unleash the Emperor's vengeance upon the followers of the Dark Gods and bring His divine light to this area of darkness. But a far more terrible foe dwells within these worlds of insanity: the ancient Chaos Space Marine Legions. With dishonour behind him and certain death ahead, Uriel must gather every ounce of courage if he is to survive and regain his honour!
