Skuld
It is said that the two eldest Norns set happy fortunes for people, while Skuld, the youngest, often changes Their decrees to more tragic outcomes. Skuld as the last of the three is the Norn who fixes the length of the thread of life, or, by some accounts, unravels what Her sisters have made. She is shown veiled, as the future is unknowable. She is sometimes considered a water spirit or even a Valkyrie, one of the swan-maidens who foretell the destiny of warriors (the word valkyrja means "She Who Chooses Warriors Destined to Die in Battle"). She rides out with the Valkyries Gunnr and Róta to choose who shall be killed.
