Fraya

Freya was the Queen of Vanaheim before the first war. Capable of using Seidr magic to see into the future, Odin came for her power to see his fate. When the Vanir refused him, he brought war into the world and the Vanir and Aesir battled beyond Vanaheim's borders. As the war progressed, the Vanir's losses were more than they could bear, so when Odin offered a treaty to end the war, the Vanir agreed despite its unfavorability. They traded their queen, Freya, to be the Aesir's hostage and Odin's wife, taking Hoenir in exchange. From the show Twilight of the gods.
