These runes are hand made using the Elder Futhark alphabet. They inclue the "Odin" or "blank" rune which is thought to be historically inaccurate, so it is up to you if you use it or not. I personally relate quite significantly to it. It has ties to "The Fool" of the Tarot.
Runes are an ancient Germanic alphabet used by the Vikings for writing, divination and magick. Divination is the art or practice that seeks to foresee or foretell future events or discover hidden knowledge usually by the interpretation of omens or by the aid of supernatural powers. Other forms of divination include tarot cards, tea leaves, scrying mirrors, and of course the crystal ball. Different forms appeal to different people, whichever works best for you is the best choice. If you are merely obsessed with vikings because it is the current trend, then these would make a great decoration but I would not recommend using them if that is the case. Dabbling with the occult can, and will be dangerous. Only serious practioners of the occult are recommended to use these for divination or magick.
Where do runes come from?
The Norse God Odin hung himself from the tree of life by his own spear for 9 days at which time branches fell off the tree onto the ground in the shape of the runes. There is much more to the story, and honestly although I do have some Nordic heritage, I'm not the foremost authority on the history and methods of the vikings so I reccommend doing your own thorough research on the subject before attempting to use these. It isn't necessary, but it is recommended.
