The Æsir, as depicted in the Eddas and sagas of Norse mythology, are a powerful and complex pantheon of gods who reside in Asgard, one of the Nine Worlds connected by the cosmic tree Yggdrasil. Led by Odin, the Allfather, the Æsir are associated with various aspects of nature, human society, and cosmic order. They include such renowned deities as Thor, the thunder god and protector of humanity; Frigg, goddess of foresight and wisdom; Tyr, god of law and justice; and Baldr, god of light and purity. These gods are deeply involved in the affairs of both the cosmos and humankind, often intervening in battles, bestowing gifts, and shaping the course of fate.

The Eddas and sagas portray the Æsir as complex beings with their own strengths, flaws, and interpersonal conflicts. They are locked in an eternal struggle against the giants (jötnar), who represent the forces of chaos and destruction. The myths surrounding the Æsir are rich with tales of their exploits, their relationships with each other and other beings, and their roles in major cosmic events such as the creation of the world and its prophesied end, Ragnarök. These stories not only provided entertainment but also served to explain natural phenomena, establish moral codes, and offer insights into the Norse worldview, making the Æsir central figures in the religious and cultural life of the Norse people.
