Cal

Cal, also known as Caleb Jerome, is the blood brother of Will and an important ally.

Cal was born in the Colony to Sarah and Mr. Jerome as Caleb. When he was barely a year old, his mother took him and his brother Will and ran away from the Colony after his newborn brother had perished. His mother knew that they were in danger and ran off with both of them to the surface world. However, she had been injured in her escape and was forced to leave Cal behind. The Styx quickly found him and returned him to the Colony, where Mr. Jerome raised him by himself. Over the years, he formed a strong bond with his uncle Tam Macaulay and his pet Hunter, Bartleby. Tam would often bring Cal souvenirs from his travels, such as candy. He was very fond of his grandmother, too, and her death shocked him strongly.
