In Norse mythology, the Einherjar are the souls of the heroic dead in Valhalla. The Vikings and Norse peoples believed that when warrirors died honorably in battle, they would be taken up to Valhalla by Valkyries. At Valhalla, in the Aesir’s home of Asgard, they await Ragnarok where they will fight alongside Odin and the other Aesir. They are valiant, courageous protectors who do not put up with any kind of offense against their Keeper or the Keeper's family as they come to regard the Keeper and the family as their own.
