A hero, by definition, possesses the courage to face challenges and confront adversaries, regardless of the obstacles that may arise. This concept is central to the ideals explored in stories like "Percy Jackson & the Olympians." The protagonist's journey illustrates that true bravery allows an individual to navigate any situation and rise to confront the unknown.

This quote from Rick Riordan emphasizes the importance of inner strength and determination in a hero's journey. It suggests that a hero's ability to venture into unfamiliar territories and stand up to formidable foes is rooted in their nerve and resolve, highlighting that the essence of heroism is not just in physical strength but in courage and character.
