Originally, Njord was one of the Vanir but when they made peace with the Aesir, he and his children were given to them as hostages. The Aesir appointed both Njord and Freyr as high priests to preside over sacrifices. Freya was consecrated as sacrificial priestess. She taught the Aesir witchcraft, an art that was common knowledge among the Vanir.
