Imagine that our everyday emotions, anger, joy, fear, and love, are not merely psychological responses, but powers that form the world's underlying rules, a kind of “higher-dimensional energy” that can be refined and absorbed.
In this world, power comes from the spectrum of emotions scattered throughout humanity's collective unconscious. The mightiest beings are those who refine a universal human emotion into a divine authority of their own, then use it to establish rules and govern reality.
