In "Dragonfly in Amber," Diana Gabaldon explores the dual nature of magic, emphasizing that its true strength and risk stem from the belief people hold in it. This highlights how the perception of magic can shape reality, impacting decisions and actions. The characters' convictions about magical elements influence their experiences and interactions, illustrating that belief can enhance or endanger one’s life.

This notion suggests that magic is not merely an external force, but rather an internal belief system that drives individuals to act in certain ways. The power of magic, then, lies in the faith people invest in it, which can lead to profound transformations or destructive consequences, depending on the nature of that belief. Gabaldon's narrative captures this tension, revealing how belief shapes destiny.
