The quote from "The Last Unicorn" by Peter S. Beagle reflects a deep sense of mortality and longing. The speaker acknowledges their human experiences of sorrow, desire, and the anxiety surrounding death, highlighting an internal conflict between their current state and the memories of their past. Even though they have transcended to become something more than mortal, remnants of longing and regret still haunt them, making their existence a complex experience.

This profound sense of regret distinguishes the speaker from other mythical creatures, particularly unicorns, who are often depicted as pure and untouched by such emotions. The realization of regret shows a depth of character and the weight of existence that transcends the boundaries of their magical nature. This exploration of identity and the emotional struggle presents a poignant reflection on existence, touching upon the universal themes of loss and the desire for connection.
