A Valkyrie out of Time...I've introduced the character of a Valkyrie as one of the leads in Spear of Odin: Son of Thunder.
What is a Valkyrie?
From Encyclopædia Britannica:
Valkyrie, also spelled Walkyrie, Old Norse Valkyrja (“Chooser of the Slain”), in Norse mythology, any of a group of maidens who served the god Odin and were sent by him to the battlefields to choose the slain who were worthy of a place in Valhalla. These foreboders of war rode to the battlefield on horses, wearing helmets and shields; in some accounts, they flew through the air and sea...
Some Valkyries had the power to cause the death of the warriors they did not favour; others, especially heroine Valkyries, guarded the lives and ships of those dear to them. Old Norse literature made references to purely supernatural Valkyries and also to human Valkyries with certain supernatural powers.

Since the Valkyrie in my story is from a different age, a different time, she views the "culture" or customs of our era skeptically, given her nature and love of battle and heroism.
Initially, her introduction takes place on earth or Midgard. But soon she and Peter, the protagonist of the story, leave our world - for a time - and her powers and abilities come to the fore. He's a little overwhelmed after their first encounter, but things change.
