The quote "I'm a magician with no magic, and that's no one at all" from Peter S. Beagle's "The Last Unicorn" speaks to a profound sense of loss and identity. It reflects the feelings of someone who once held power or significance but now feels empty and ineffective. This resonates with the themes of the book, where characters grapple with their purpose and what it means to exist when stripped of their true essence.

In this context, the character's declaration emphasizes the struggle between one’s potential and current reality. It suggests that without the distinct qualities or abilities that define us, we may feel like mere shadows of our former selves. The quote invites readers to ponder the importance of magic—both literal and metaphorical—in their lives and the impact of losing what makes us unique.
