When the battle is coming to a close (after 50 HD of creatures have perished and either Krev Ragata or Countess Veresovich are no more) and the floors of the chamber are bathed in the blood of the dying or fallen, the Exsanguinator finally appears! Read the following when it seems the battle against Cultus Sanguineus has reached an end:
The deranged cultists are falling before you, their corpses piling up as the floor itself becomes coated with the blood of the newly dead. As the battle begins to wain, you notice that the sloshing crimson has risen to cover your feet and is beginning to steam. Booming laughter echoes from the walls of the chamber as the blood flooding the room generates waves from nowhere before forming into an enormous creature in the center of the room.
It floats in the air with its legs crossed, instantly scrutinizing you from behind calculating, immortal eyes. Two curious horns sprout from the red flesh of its head and it wears nothing save a simple, torn yellow loincloth. You can sense its hunger immediately—whatever it is, it instinctively yearns for blood. In an instant, the gallons of it that occupied the chamber are sucked away entirely as the creature fully forms and the maniacal laughter turns into an angry battle roar!
