A Norse god refers to a deity from the mythology of the ancient Norse people, primarily from Scandinavia. These gods were believed to inhabit realms such as Asgard and were associated with various aspects of life, nature, and human experience. Key figures include Odin, the chief god known for wisdom, and Thor, the god of thunder, who wielded a powerful hammer. Norse gods were often depicted in stories and sagas, which explained their adventures and relationships with humans and other beings, such as giants and elves. Worship of these gods was common in Viking culture, influencing their rituals and beliefs about the afterlife, including Valhalla.
