Dís
In Norse mythology, a dís (Old Norse: [ˈdiːs], "lady", plural dísir [ˈdiːsez̠]) is a female deity, ghost, or spirit associated with Fate who can be either benevolent or antagonistic toward mortals. Dísir may act as protective spirits of Norse clans. It is possible that their original function was that of fertility goddesses who were the object of both private and official worship called dísablót, and their veneration may derive from the worship of the spirits of the dead. The dísir, like the valkyries, norns, and vættir, are always referred collectively in surviving references. The North Germanic dísir and West Germanic Idisi are believed by some scholars to be related due to linguistic and mythological similarities, but the direct evidence of Anglo-Saxon and Continental German mythology is limited. The dísir play roles in Norse texts that resemble those of fylgjur, valkyries, and norns, so that some have suggested that dísir is a broad term including the other beings.
