In "The Last Unicorn," Peter S. Beagle suggests that the journey of a hero is marked by significant challenges and emotional turmoil. These hardships are essential to their greatness, as they shape the character and depth of the hero, allowing their strength to shine through. Without these struggles, their true potential may remain hidden, making their achievements less impactful.

The quote highlights the idea that suffering and adversity are intrinsic to the heroic narrative. It implies that greatness is not merely about triumph, but also about the profound experiences that define a hero's journey, as seen in many fairy tales. Such burdens add texture to their story, making the moments of victory even more poignant and meaningful.
