According to the Norse legends, Gungnir is made from the wood of the world tree Yggdrasil and is so mighty and well balanced that it could hit and destroy any target, regardless the skill or strength (or lack of thereof) of the wielder.
In German folklore, the Weiße Frauen (meaning White Women) are elven-like spirits that probably have originated in Germanic paganism in the form of legends of light elves (Old Norse: Ljósálfar).
They are described as beautiful and enchanted creatures who appear at noon and can be seen sitting in the sunshine brushing their hair or bathing in a brook. They may be guarding treasure or haunting castles. They entreat mortals to break their spell, but this is always unsuccessful.
