The Hero's Journey is a narrative framework identified by Joseph Campbell in his book, 'The Hero with a Thousand Faces.' It outlines a common pattern found in many myths and stories across cultures, where a hero embarks on an adventure, faces challenges, and ultimately returns transformed. This journey typically includes stages such as the call to adventure, crossing the threshold, and the return home. This structure has influenced countless stories in literature and film, from Star Wars to The Lord of the Rings. By following this archetypal path, storytellers can create compelling narratives that resonate with audiences on a deep emotional level.
