During the turbulent Reign of Blood, a great schism in the Imperial Ecclesiarchy threatened all of Terra and promised a darkness to rival the terrors of Old Night. Fell times have come again to the Imperium, and a War of Faith appears inevitable. Standing in the way of catastrophe is Celestine, the Living Saint and one of the greatest heroes of the age. Only she can reunite the warring factions of the Ecclesiarchy and prevent a second Reign of Blood.

With her mighty wings spread wide and Ardent Blade aflame, Saint Celestine is the living embodiment of the God-Emperor’s wrath. Her halo blazes like a star upon the smog-wreathed, blood-soaked battlefields of the 41st Millennium; its holy light leading the faithful to victory time and time again. As heretics and daemons tear at her flesh, she calls down fires of retribution from on high to smite the wicked and unrighteous. If she is to fall in battle, none should mourn as she is Celestine, the Living Saint, and death is her duty.

But the way to the Throne will be hard as the primarch Rogal Dorn, the Praetorian and protector of Terra, marshals the defences.
