Norse Mythology: Goddess of sex, fertility, war, and wealth. Originally one of the Vanir. She was the daughter of Njord, and the sister of Frey. Her daughters, by Od, are named Hnoss, who is so beautiful that whatever is valuable and lovely is named "treasure" after her, and Gersemi. 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 male cats (their names are never stated) 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.
