It certainly could be a different casting system. There seems to be a lot of them now. Good luck and keep learning! :)

You have the correct name of the rune but that one is typically associated with an extinct cattle like creature called an Arouchs noted for its strength and tenacity, which is the typical meaning of this rune.

I don’t think that’s Odin‘s rune. Typically what I’ve seen is Odin’s rune is a blank rune used in some rune systems, but not all. It’s a rather controversial rune to be used in some circles as it is not considered historically accurate.
