As the adopted son of King Harrow, Callum is the “step prince” of Katolis. He’s an awkward fit for the role of a prince: Callum can hardly hold up a sword, he falls off every horse he tries to ride, and he isn’t quite sure how to act around his stepfather, the King. Nonetheless, Callum has a big heart and tries his hardest at everything, no matter how many times he falls down — he knows that one day, he’ll find his place in the world.
