As the angry Wotan states that Brünnhilde must become mortal and marry the first man she sees, so does his word become law, unable to be retracted. His favorite daughter only asks that the man she is to marry be not a coward. Remembering why she is his favorite, Wotan then devises a way to grant her request. He puts her in a deep sleep, only able to be awakened by a man proving himself brave by stepping through the fire Wotan commands Loge to encircle her with.
