Mikal owned the largest pottery in Del. He sheltered and fed Josef and Ranesh in his cellar when they came to the city. Soon after the invasion of the Shadow Lord, Mikal and his family were captured and his pottery was raided, and they were taken to the Shadowlands.
While the rest of his family's whereabouts are unknown, Mikal was sent to the Factory to be experimented on. Before the experiment was completed, he escaped inside a cave through a hallow under a rock. The experiments gave him talon-like claws, and he changed his name to Claw to match it.
He formed a new Resistance group by saving people wandering the Shadowlands, including Gers and Brianne of Lees.
Claw and his men captured Lief, Barda, and Jasmine shortly after they entered the Shadowlands. After hearing their story, Claw agreed to join forces with them to free the captured Deltorans. He and Gers snuck into the Shadow Arena and freed the slaves from their shackles. This allowed Lief and Emlis to play the Pirran Pipe long enough for the Pirrans to rescue everyone.
