The viking (nordic, or norse) gods and goddesses are:
Odin was the chief god in the Norse mythology, and the father of Thor, Balder, Hoder, Tyr, Bragi, Heimdall, Ull, Vidar, Hermod and Vali. His wives were Fjorgyn, Frigga and Rind. He had a bad habit to roam around Midgard in human disguise seducing and impregnating women. His name is related to ōðr, meaning “fury, excitation,” besides “mind,” or “poetry.”
Thor (from Old Norse Þórr), meaning thunder, is a hammer-wielding god associated with thunder, lightning, storms, oak trees, strength, the protection of mankind, and also hallowing, healing and fertility. Thor was the son of Odin and Fjorgyn. He was the god of thunder, the sky, fertility and the law. Armed with his strength-giving items, a belt and the hammer Mjölnir, he had a simple way of righting wrongs: he more or less killed everything that moved. The other gods -mostly Loki- occasionally took advantage of Thor’s simplicity.
In Norse mythology, Loki or Loptr is a god or jötunn (or both). Loki is the son of Fárbauti and Laufey, and the brother of Helblindi and Býleistr. By the jötunn Angrboða, Loki is the father of Hel, the wolf Fenrir, and the world serpent Jörmungandr. By his wife Sigyn, Loki is the father of Nari or Narfi. And by the stallion Svaðilfari, Loki is the mother—giving birth in the form of a mare—to the eight-legged horse Sleipnir. In addition, Loki is referred to as the father of Váli in the Prose Edda. Loki can be called the ‘wizard of lies’ and is in many ways the most interesting god in Asgard. Loki was related to Odin, but their relationship was rather strange. He came to Asgard either as of right or because Odin and he entered into a blood-brotherhood.
Freyr (sometimes anglicized Frey, from *frawjaz “lord”) is one of the most important gods of Norse paganism. Freyr was associated with sacral kingship, virility and prosperity, with sunshine and fair weather, and was pictured as a phallic fertility god, Freyr “bestows peace and pleasure on mortals”. Freyr, sometimes referred to as Yngvi-Freyr, was especially associated with Sweden and seen as an ancestor of the Swedish royal house. Frey was a fertility god of the the Vanir race. He was the son of Njord and came to Asgard as a hostage along with his father and sister Freya.
Freyja (Old Norse the “Lady”) is a goddess associated with love, beauty, fertility, gold, seiðr, war, and death. Freyja is the owner of the necklace Brísingamen, rides a chariot pulled by two cats, owns the boar Hildisvíni, possesses a cloak of falcon feathers, and, by her husband Óðr, is the mother of two daughters, Hnoss and Gersemi. Along with her brother Freyr (Old Norse the “Lord”), her father Njörðr, and her mother (Njörðr’s sister, unnamed in sources), she is a member of the Vanir. Stemming from Old Norse Freyja, modern forms of the name include Freya, Frejya, Freyia, Frøya, Frøjya, and Freia.
Freyja rules over her heavenly afterlife field Fólkvangr and there receives half of those that die in battle, whereas the other half go to the god Odin’s hall, Valhalla. Freya was the goddess of sex and later also war and death. She married the god Od, who deserted her. After being abandoned she divided her time between mourning his absence and being promiscuous.
The goddess of spring and immortal youth was called Idun. She was the daughter of the dwarf Ivald and married to the god Bragi. The name Iðunn has been variously explained as meaning “ever young”, “rejuvenator”, or “the rejuvenating one”. As the modern English alphabet lacks the eth (ð) character,Iðunn is sometimes anglicized as Idun, Idunn or Ithun. An -a suffix is sometimes applied to denote femininity, resulting in forms such as Iduna and Idunna.
Sif was the goddess who married Thor and bore his stepson (by Odin), Ull. The vikings (and their gods) admired golden hair, and she was exceptionally proud of hers, so Loki cut it all off while she was asleep. The name Sif is the singular form of the plural Old Norse word sifjar. Sifjar only appears in singular form when referring to the goddess as a proper noun. Sifjar is cognate to the Old English sib (meaning “affinity, connection, by marriage”)
Hel was a goddess (or a monster), a daughter of Loki and Angrboda, who ruled over Niflheim, which was the land of the dead. There were different opinions of whether she was alive or dead. Ull, in his role as god of winter, was supposed to spend a few months each year as Hel’s lover. Hel and her ghostly army were going to support the other gods at Ragnarok, after which her domain would go out in flames.
