Throatslitter was a member of the 9th Squad of the Bonehunters. He was Hengese by race, and had been trained as an assassin. Due to repeated damage to his throat, his laugh became something to make anyone's hair within a league stand on end. He had scars on his neck.
He was an active member of the Talon inside the army, and generally approached life as such, choosing to gather as much information as possible between squads. It was also known for him to be in active contact (though still keeping his anonymity) with another Talon member inside the army.
Throatslitter had taken a shot to his chest during the battle with the K'Chain Nah'ruk but survived due to his chain mail. The impact dented his sternum however and impacted on his voice, which had turned into a cracking rasp.
