Vanir
The Vanir are one of the two pantheons of gods in Norse mythology, together with Æsir. They include Niordr, Freyr and Freya, who live among the Æsir since the end of the conflict between the two clans of gods (traded for Mímir and Honir), as well as Skadi, Lýtir, Gerdr and Odr.
They live in Vanaheimr, also called Vanaland; Snorri Sturluson calls their land Tanakvísl or Vanakvísl.
They are gods of fertility and prosperity, and they are seen as belonging to the earth, while the Æsir ruled the sky.
The Vanir have a deep knowledge of magical arts, so that they also know the future. It is said that it was Freya who taught magic to the Æsir.
They also practiced endogamy and even incest, both forbidden among the Æsir; as an example Freyr and Freya were children of Niordr and his sister.
