...and the youngest Norn, she who is called Skuld, ride ever to take the slain and decide fights...Faroe stamp by Anker Eli Petersen depicting the norns (2003).
Skuld (the name possibly means "debt" and is related to the English word "should") is a Norn in Norse mythology. Along with Urðr (Old Norse "fate") and Verðandi (possibly "happening" or "present"), Skuld makes up a trio of Norns that are described as deciding the fates of people. Skuld appears in at least two poems as a Valkyrie.
In the Prose Edda book Gylfaginning, Snorri informs the reader that the youngest Norn, Skuld, is in effect also a valkyrie, taking part in the selection of warriors from the slain:
These are called Valkyrs: them Odin sends to every battle; they determine men's feyness and award victory. Gudr and Róta and the youngest Norn, she who is called Skuld, ride ever to take the slain and decide fights."
