Faroe stamp by Anker Eli Petersen depicting the norns (2003)]] Skuld ("debt" or "obligation"; sharing etymology with the English "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.
