As depicted by Cassandra Jean.
Callum Hunt, often called Call, is the main protagonist of The Magisterium set to make his debut in The Iron Trial.
Call has dark hair and gray eyes. Although his height is average for a twelve-year-old, one of his legs is shorter than the other. He has had surgeries on it to correct it since he was a child but none of them worked. His leg hurts often. Call is described as cranky. He hates people commenting on his limp, he rides a skateboard sometimes, and he once kidnapped a naked mole rat.[1][2]
