Frey in Norse mythology was an important god of the Vikings. In Old Norse, "Frey" meant master; the Third Doctor and Jo Grant found out when meeting Odin, Thor and other gods of Norse mythology that Frey was actually, who was out to get Gungnir, Odin's time-controlling spear, in the Sweden of the year 141.
