The adversary of light in various mythological traditions is often represented by figures such as Set from Egyptian mythology or Loki in Norse myths. Set embodies chaos and darkness, opposing the sun god Ra, symbolizing the struggle between good and evil. Similarly, Loki represents mischief and disorder in Norse tales, often clashing with the gods and introducing elements of strife. These figures personify the challenges of darkness and chaos, reminding societies of the balance necessary to thrive in a morally complex universe.
