Fan Casting Freyja in Valkyries

Liv Tyler as Freyja: The goddess of war and gold, former queen of the Valkyries, and Arianna's older half-sister and mentor who is legally deceased, but is actually alive and trapped in Helheim. Unlike her Norse Mythological counterpart, she is a daughter of Odin and Frigg (with her father not being Arianna's due to being her half-sister).
