Before reading the books I saw the movies, and when I started reading the books I assumed that Murlough was gonna look the same as in the movie. Oh boy was I wrong.
In the books he is this big monster-like size with red hair and purple skin. Y'know not as handsome as he is in the movie lmao.
If Murlough was an animal, I think he would be a cross fox or a Wolverine.
Personally, I headcanon that Murlough has a blood fetish. Sorry not sorry lol.
