Reaper Priest

"Screams flood the streets as you all fruitlessly fight against the insurmountable swarms of people in black robes. When one goes down another simply takes their place, as they silently collapse to the ground dead. You wonder if they're anything more than cloth as you slice through them, although they certainly feel and act like people, and hit like them too. Once, twice, thrice... you're caught in the face by another sword and another. More wounds appear steadily as fire is now spreading in the surrounding area, as apparently one of the figures are casting spells. Just as you slash through another, a hideous rasping breath catches your attention as you look over, and there IT stood, rising from the fire as if born from it, and you wouldn't doubt it if such was told to you as fact."

One of the other antagonist types my PCs fight against. Called "the Reapers" and this is a special type of unit they use.
