Freyja is from Norse mythology. Freyja is a major Vanir goddess, associated with many things, but particularly with war and seeing and shaping the future, love and fertility. Her name means lady or mistress in Old Norse. She is the daughter of the Vanir god Njordr and the twin sister of Freyr. Her mother’s identity is a mystery to many scholars and is simply called the unnamed wife of Njordr. Some sources however suggest that Hertha is the mother of Freyja and Freyr. After the Aesir-Vanir war, peace was established between the two divine forces. In order to strengthen that treaty Njordr and his children, Freyr and Freyja agreed to be exchanged with other Vanir hostages. They were quickly accepted into the ranks of their former enemies as honorary members and became invaluable to the gods of Asgard. Freyja ruled the heavenly field Folkvangr. She often rode her chariot – pulled by two white cats – into battle to claim her share of the dead. She would select half of the slain and carry them to her splendid hall of Sessrumnir. The other half were chosen by the Valkyries and brought to Odin’s hall of Valhalla. She is particularly invaluable to the gods because of her cloak made of falcon feathers given to her by her father. The legendary, mythical garment the goddess wears to transform herself into a falcon. Her falcon-feathered cloak allows the wearer to fly, usually in the form of a falcon, demonstrating Freyja's connection with shape-shifting magic - an aspect of Seidhr trance magic.
