The quote from Peter S. Beagle’s "The Last Unicorn" reflects the speaker's regal identity and aloofness. The phrase "I am a king's daughter" signifies a position of privilege and responsibility, while the notion of not caring suggests a disconnect from the expectations that come with her title. This creates an image of a woman who is aware of her royal status yet chooses to remain detached from its burdens.

The imagery of the "moon that has no mistress" fluttering in her hair evokes a sense of freedom and whimsy. It highlights her desire for autonomy, as she prefers to embrace the beauty of the natural world rather than conform to societal norms. Through this quote, Beagle encapsulates themes of identity, freedom, and the complexities of royal obligations.
