In Old Norse, ǫ́ss (or áss, ás, plural æsir; feminine ásynja, plural ásynjur) is the term denoting a member of the principal pantheon in the indigenous Germanic religion known as Norse religion. This pantheon includes Odin, Frigg, Thor, Baldr and Týr. The second pantheon comprises the Vanir. In Norse mythology, the two pantheons wage the Æsir-Vanir War, which results in a unified pantheon.
