You don't think they had a fish as a rune symbol? I can guarantee you they ARE the same thing. A rune is a letter OR a representation or symbol. Othala Rune is also similar to the use of the Christian Fish in the first century A.D. The use of that symbol in those days was derived from a simple ancient estoeric meaning created by our ancestors. The Othala rune shape represents a fish that is going against the downward flow of time. It is a transcendent rune and thus has a place among Tyr’s Aett.
