Freya — Old Norse Freyja, meaning simply "Lady" (as Freyr, her brother, means "Lord") — is the foremost goddess of the Vanir, one of the two groups of Norse gods. The Vanir are associated with fertility, magic, wisdom and the natural world; the Aesir (Odin's tribe) with war, kingship and cosmic order. After the war between the two groups, a peace was made and hostages exchanged — Freya, her brother Freyr and their father Njörðr came to live among the Aesir. Freya brought with her the most powerful magic known to the Norse world: seiðr.
She is the daughter of Njörðr (god of the sea and winds) and the twin sister of Freyr (god of fertility, sunlight and rain). Her husband is Óðr — a mysterious figure who wanders away for long periods, causing Freya to weep tears of gold in her grief and search for him across the worlds in disguise. Some scholars have identified Óðr with Odin himself; others treat them as distinct figures. What is clear is that Freya's grief for Óðr — her tears of gold, her disguised wanderings — mirrors Odin's own characteristic wandering and loss.
Freya's hall is Fólkvangr — the "Field of the People" or "Field of the Host" — where she receives half of all those slain in battle. The other half go to Odin's Valhalla. This is a fact that is easy to pass over but is theologically significant: Freya has first choice of the battle-slain before Odin receives his portion. The goddess of love has equal claim on the dead warriors as the god of death and war. The association of love and death — the fundamental insight of much of the world's greatest literature — is built into the structure of Norse mythology.
She is depicted riding a chariot drawn by two large cats, wearing the falcon-feather cloak that allows her to transform into a falcon, and bearing the magnificent necklace Brísingamen — the most beautiful object in the nine worlds, which she obtained at enormous personal cost. She is simultaneously the most desirable and the most formidable of the goddesses — desired by giants, sought by dwarves, valued beyond price by gods — and she consistently refuses to be possessed, bargained away or controlled.
