It's a cycle.It explains every hero's story. Kind of like a clock. It starts by 1 o'clock call to adventure, 2 o'clock supernatural aid, 3 o'clock the threshold, 4 o'clock temptations and challenges, 5oclock mentor or helper, 6 o'clock crisis moment, 7 o'clock transformation, 8 o'clock atonement, 9 o'clock return. Then having the epic hero empowered. Just like Spider-Man, The Hunger Games, and even Star Wars. "The hero with a thousand faces."
