The heroes journey is illustrated in this description through several details. The outline of this trope sees a person responding to a call to action, this being Gia wanting to destroy the world. Then, the next element is a journey from their common surroundings to a "new world", or unfamiliar place, akin to the journey away from their normal camps. Then, another is the status quo, shown in their return home. Here, they attempt to make things better, uniting camps across two nations.
