Baldur

Baldur the Beautiful, (PROSE: A Hundred Words from a Civil War) or Balder, (PROSE: The Spear of Destiny) was a god in Norse mythology.

The Eighth Doctor told Izzy Sinclair that the Norse worshiped gods that included Frey, Thor, and Baldur. He also said they were more "rough and tumble" when compared to their comic book personas. (PROSE: Illumination)
