Deives
Fairies

Deives are Lithuanian spirits who sport two faces: they manifest as fierce old hags and as big-breasted, blue-eyed beautiful women with long blonde hair. Deives protect women, supervising their work and spiritual traditions. Rules of the deives included no laundering after sunset (that’s when the deives go swimming), and no spinning on Thursdays. They punish men who fail to respect these rules and force women to break them. Deives also allegedly dislike greed, excessive acquisitiveness, and selfishness.
