The Aesir 

Aegir

His name is connected with the word for water. He is also called Hler. Aegir was the god of the seashore or ocean, and called the ruler of the sea by Snorri. He was a personification of the ocean, be it good or evil. He caused storms with his anger and the skalds said a ship went into "Aegir's wide jaws" when it wrecked. Guerber states that Aegir was crowned with seaweed and always surrounded by nixies and mermaids while in his hall.

He was one of the Vanir and a giant.

His father was Mistarblindi [Mist-Blind], and his brother, Logi [Fire].
Aegir's wife (and sister) was Ran and they lived under the sea by the island Hlesey. Ran and Aegir had nine daughters who were the waves -- all of their names are poetic names for waves.
Aegir brewed ale for the gods after Thor brought him a big enough kettle. Every winter the gods would drink beer at Aegir's home. He was, therefore, famed for his hospitality.
Gold was put onto the floor of the hall to provide light, instead of having a fire. Gold is therefore called Aegir's fire. The cups in Aegir's hall were always full, magically refilling themselves.

Aegir had two servants in his hall, Fimafeng [Handy] and Eldir [Fire-Kindler]. According to Lee Hollander, Aegir's function as the gods' ale brewer was suggested by the ocean's foam. After the death of Balder, the gods gathered for a feast in Aegir's hall. Loki showed up and insulted everyone (this is told in Lokasenna in the Poetic Edda).

The gods ouldn't do Loki harm in the hall since it was a sanctuary where no violence could be committed. Aegir was also referred to by the name of Gymir [the Blinder] (the name of Gerd's father -- it is not known if they are one and the same). Sailors feared Aegir, and thought he would sometimes surface to destroy ships. Early Saxons made human sacrifices to a god of the sea, possibly connected with Aegir.

Balder

One of the Aesir, his name means "The Glorious". He was also called the "god of tears" and the "white as". Balder, the son of Odin and Frigg, was described as a very handsome and wise god. Some consider him to be a god of light since he was so bright, light shined from him.

Balder's wife was Nanna and they had a son named Forseti. Balder and Nanna lived in Breidablik [The Broad-Gleaming], where nothing unclean could be and there were "fewest baneful runes". Breidablik had a silver roof on golden pillars.

t one point Balder had a foreboding dream. Odin rode to Hel's realm to wake a volva from the dead to find out the meaning of Balder's dream. She foretold Balder's death by Hod (Hodur), his fraternal twin.

Frigg asked all things to swear not to hurt Balder but didn't ask the mistletoe because it was so young. Loki, diguised as an old woman, visited Frigg and found out Balder was invunerable to everything but mistletoe. Loki made a dart out of mistletoe and tricked the blind god Hod into throwing it at Balder -- all the other gods were playing games by throwing various items at Balder --, thus killing him. Hermod rode to Hel's realm and got her to agree to let Balder return to the living if all things would weep for him.

One giantess named Thokk, Loki in disguise, refused to weep for Balder, so he remained dead and was cremated on his funeral boat, hringhorni. He is supposed to come back to life after the Ragnarok. Snorri and Saxo Grammaticus give very different views of Balder and his death.

In Saxo's version of this story, Hod is alone responsible for Balder's death. Saxo gave a very different picture of Balder: he was a vicious god who fought with Hod to marry Nanna. Balder's name  arely occurs in place names, therefore, it is thought that not many people worshipped him. The poets used his name to mean warrior.

Bor

Son of Buri. His wife was Bestla, daughter of the frost giant Bolthorn. Bor was the father of Odin, Vili, and Ve.

Bragi

God of poetry, (adopted?) son of Odin and the giantess Gunlod. He was the chief poet of Odin. He was married to Idun and he had runes cut on his tounge. There was a 9th century skald named Bragi Boddason and some believe he may have been raised to a god by later writers. Others believe Bragi was a pseudonym of Odin.

Buri

The first god. The cow Audumla formed him by licking ice. He was the father of Bor.

Eir

A goddess of healing, considered the best doctor. She taught her art to women who were the only physicians in ancient Scandinavia.

Forseti

God of justice. He is the son of Balder and Nanna. His name means "presiding one" and in The Poetic Edda, it says he is "the god that stills all strife." His home is Glitnir [shining].

Frey

God of weather and fertility. He ruled over the land of the light elves, Alfheim. He was the son of Njord and Njord's sister, and the brother of Freya.
His step-mother was Skadi. To make peace, the Aesir and Vanir exchanged hostages. He, along with Njord and Freya, were sent by the Vanir to dwell with the Aesir. He owned the ship Skidbladnir which was made for him by dwarves. It could sail on the land, sea, or through the air. It was large enough to hold all the gods, yet could be folded up and fit into a pocket. He also owned a chariot drawn by two boars, Gullinbursti and Slidrugtanni. He could ride Gullinbursti [golden-bristled] through the sky. It was made by dwarfs for Loki to give to Frey.
His name means "Lord" and it is thought that he was at one time the consort of his sister Freya [Lady]. His wife was Gerd, a beautiful giantess who he fell in love with when he espied her from Odin's throne. He sent his servant, Skirnir, to win her for him. For this task, Frey lent Skirnir his sword which "swings itself if wise he who wields it" and his horse. After Skirnir's threatening of her, Gerd agreed to give herself to Frey in nine nights at the forest Barri.

At the Ragnarok, Frey will be killed by the fire giant Surt. Also known as Yng, Frey is named as the progenitor of the swedish royal family. There was a statue of Frey in the temple at Uppsala in Sweden, the center of his cult.

Freya

Goddess of love, fertility, war, and wealth. Originally one of the Vanir. She was the daughter of Njord, and the sister of Frey. Her daughter, by Od, is named Hnoss who is so beautiful that whatever is valuable and lovely is named  "treasure", after her. She lived in Folkvang [battlefield] and each day chose half of the slain warriors to split with Odin.

She had a husband named Od, whom she somehow lost and cried golden tears for. Many believe Od is Odin. Her chariot was drawn by cats and she owned the precious Brisings' necklace, which she slept with four dwarves to acquire. She also owned a feather coat which she could use to fly between the worlds. After she went to live with the Aesir as a hostage, she taught them -- including Odin -- seidr. Some sources say Friday is  named after her.

Frigg

Goddess of marriage. She is the wife of Odin, and Friday is named for her (according to some). Her abode was called Fensalir [The Ocean Halls]. She weaved the clouds.

Fulla (Volla)

Listed by Snorri as one of the twelve divine goddesses, she appears mainly to function as Frigg's maid, taking care of the goddess's shoes. She also, sometimes, functions as Frigg's messenger. Some believe she is Frigg's sister.

Snorri stated she was a virgin with long golden hair who wore a gold band around her head. It has been suggested that this band represents the binding around a sheaf of grain.

Gefjon

A prophetic virgin goddess and a member of the Aesir and Vanir. All women who die virgins go to her hall. She was also a fertility goddess. In one myth, Gylfi, king of Sweden, tells Gefjon, who was disguised as a beggar, that she could have as much of Sweden as she could plough with four oxen in one day. She traveled to Jotunheim and found her four oxen sons whom she had by a giant (she isn't a virgin in this myth!). She returned to Sweden in Midgard with her sons and ploughed all of the land now known as Zealand so it became part of Denmark, thereby tricking Gylfi. Her name means "Giver".

Gna

Listed by Snorri as one of the divine goddesses but appears only to be a handmaiden of Frigg who sends her on errands. She has a swift horse named Hoof-flourisher which can run in the air and over water.

Gullveig

A Vanir goddess. The Aesir's attempt to kill her brought about the first war in he world (the Vanir against the Aesir) which the Vanir won. The two tribes exchanged gods and then ruled together. Gullveig [Power of Gold] has been identified by some as the Triple Goddess, which was prevalent throughout the old world. Also called Heid [witch]. According to some she is Freya.

Heimdall

Watches the rainbow bridge, Bifrost , for the coming of the frost giants at the Ragnarok, at which time he will sound his horn Gjallar. In the Ragnarok, he and Loki will kill each other. He never sleeps, can see in the dark, and can hear sheep wool growing. His dwelling place is Himinbjorg [heavenly mountains]. Nine sisters, signifying the waves, gave birth to him. As Rig, he begets Thrall, Carl, and Earl, representing the three classes of man; slave, freeman, and noble.

Hel

Daughter of Loki and the giant Angurboda. She is the sister of Fenrir (Fenris-wolf) and Jormungand (Midgard serpent). She is the goddess of the  underworld. Her realm was Niflheim and her hall, Elvidnir [misery]. She was described as half white and half black.

Hermod

Messenger of the gods. He rode to Hel's realm after the death of Balder to try and convince her to let Balder come back from the dead.

Hlin

Snorri lists Hlin as a goddess charged with protecting those men who Frigg wants kept safe. Called by others a goddess of consolation who was supposed to "kiss away the tears of mourners". In most sources, Hlin is just another name for Frigg.

Hod

Son of Odin. He is the blind god of winter, who is tricked by Loki into killing Balder. His name means "war". Vali, a son of Odin, avenged Balder's death by killing Hod.

Hoenir

After the war between the Aesir and the Vanir, he was sent as a hostage to the Vanir. He gave sense to the first humans. He possibly was Vili, a brother of Odin who helped create the world.

Huldra

A goddess who was attended by wood nymphs. They had cow tails which could be seen hanging out from beneath their white robes. They were the protectors of cattle, and sang beautifully. She is an aspect of Frigg.

Idun

Goddess who is married to Bragi and is the keeper of the apples which keep the gods eternally young. The storm giant Tjasse abducts her and the gods start to age until Loki kills the giant and retrieves Idun. Goddess of youth, her name means "The Rejuvenating One".

Jord

Earth goddess. Mother of Thor and Frigg.

Kvasir

His function depends on which source you read, like many of the Norse god/goddesses. In one myth, he is the wisest of the Vanir and sent to the Aesir as a hostage in a peace making process. In another tradition, he is created when the Aesir and Vanir mix together their spit in a peace making ritual. He is the wisest being. Later on, he is killed by dwarves who make his blood into mead, the mead of poetry.

Lodur

He gave appearance and speech to the first humans. He is identified with Ve by some and Loki by others.

Lofn

Goddess concerned with sparking passionate love. She had permission from Odin and Frigg to do so even for those who were forbidden to marry.
