Norse Rune Casting
Some evidence that, in addition to being a writing system, runes historically served purposes of magic. 5th to 7th century shows historic evidence of people castings lots. Throwing symbols on ground while offering prayers to the gods, like Norse god Odin, for answers to questions. From German people to the Vikings all questioned the rune casting. In modern times they had a blank rune, this was Odin's rune. The rune of the beginning and the end, representing the divine in all human transactions. The absence of a symbol on Odin's rune is a gift. A gift from Odin for you to choose whatever it is that you want and put that symbol inside his rune. Beware Odin's messages can be a hard and difficult journey even for a man. He rarely gives a blank rune.
