Dreadblade Harrow

This is what happens when you refuse to be proactive, kids.

"In seeking to make no enemies, I've succeeded in making no friends,"

– The title character from "The Bat, Birds, and The Beasts", Aesop's Fables

The Dreadblade Harrows (what do these names even mean anymore?) are the Lieutenants of the Nighthaunt processions. They’re what happens to you when you decide to sit on the fence about one too many a thing. That’s right, you can now be condemned to an awful afterlife for... being neutral on things. Cheers Nagash.

However, there’s no need to panic. You won’t be made into a Harrow for something incredibly small like not preferring Coke or Pepsi, or larger like not being able to be have a full-time job. No, those who become Harrows are only so because they saw the signs of a betrayal from their leader (often from a future Knight of Shrouds) and decided not to do anything about it to be on the winning side. Because of their selfish fence-sitting, their forms are some of the most ethereal of all the Nighthaunt, their very beings flickering in and out of reality.

In battle, they act as outriders and scouts, disappearing and reappearing at will to perform tasks that no honourable knight would ever do (ie, culling the weak, attacking retreaters, kicking puppy dogs in the shin, etc).
