Walter, or Walter the Shredder, is a retired Caelrig general and is now a butler who served house Raddicus. He is assigned to be the personal butler of Lynn and due to the time they spent together, she thinks of him as a father figure since her "father", Count Henry, didn't spend as much time with her.
Walter wields a pair of gloves that can control magical wires that can pierce armors and walls and cut his enemies to pieces, earning him the nickname "The Shredder". He can also augment magical elements to his wires. Count Vlad mentioned that he learned how to wield this weapon from someone.
