Odin was one of the primary gods of Norse mythology and
principally a god of war. Slain warriors were permitted to join
him in Valhalla, escorted by the Valkyrie, his maiden servants.
However, there is no rune with the name of “Odin”. Instead, this
is actually the othala rune, which became associated with Odin.
It has been adopted by neo-Nazis as a symbol of their cultural
heritage and an attempt to connect themselves with ancient Norse
mythology. Othala is the Germanic name of this rune, also known
as ethel in Anglo-Saxon, and given the modern phonetic value of
“O”. Its traditional meaning is associated with inherited land
and is also sometimes referred to as the Odin Rune.
