|Karsh is a concept which has only appeared in an adaptation of the works of J.R.R. Tolkien.|
Karsh the Whisperer or Carthedan is a noncanon character, created specifically for EA's The Lord of the Rings: The Battle for Middle-earth II: The Rise of the Witch King. He is voiced by Jason Connery.
Originally, Karsh was an Arnorian celebrated general named Carthedan. He defended Cardolan, where the burial grounds of the deceased kings of Arnor lied, from the Witch-king and his servants. He failed, and at the end, the Witch-King turned him into the wraith Karsh. Since then, Karsh is devoted to the Iron Crown of Angmar. Karsh is playable as a hero in the Angmar faction.
