Hildr is one of the nine corrupted Valkyries located within the labyrinth on Niflheim.
In Norse mythology, Hildr (Old Norse "battle") is a valkyrie. Hildr is attested in the Prose Edda as Högni's daughter and Hedin's wife in the Hjaðningavíg. She had the power to revive the dead in battlefields and used it to maintain the everlasting battle between Hedin and Högni.
Hildr is also mentioned along with other valkyries in Völuspá, Darraðarljóð and other Old Norse poems. The Old Norse word hildr is a common noun meaning "battle" and it is not always clear when the poets had the valkyrie in mind, as a personification of battle.
- In legend, Hildr is the Mistress of Battle. Unlike her sisters, whom she doesn't get along with, Hildr got along quite well with the Allfather. Hildr would spend most of her time in Midgard, observing discord between the living and causing some herself at times. As she lived for conflict, many thought she was conflict personified.
