In various mythologies, the role of an oracle or seer is often embodied by figures like the Oracle of Delphi in Greek mythology or the Norns in Norse tradition. These characters have the ability to foresee the future and provide guidance, acting as intermediaries between the human and divine realms. Their prophecies can influence the course of events, often serving as pivotal moments in mythological narratives. Through their visions, oracles convey important lessons about fate, choice, and the consequences of actions, shaping the destinies of both heroes and gods alike.
