Scarback was a ruthless weasel assassin in Swartt Sixclaw's horde. He and fellow assassin Marbul had been with Swartt Sixclaw since the foundation of his army. They were responsible for killing Lardtail. Scarback and Marbul were killed in the center of camp at night when they were strangled by some of Krakulat's crows with a thin wire while sleeping as retribution for killing the crow leader's mother. It is possible that even if he and Scarback survived, they would have been slain by Swartt's orders for sleeping on duty.
