"Nornir" (ca. 1884) by J.L. Lund, depicting Verðandi with wings.
In Norse mythology, Verðandi (Old Norse, meaning possibly "happening" or "present"), sometimes anglicized as Verdandi or Verthandi, is one of the norns. Along with Urðr (Old Norse "fate") and Skuld (possibly "debt" or "future"), Verðandi makes up a trio of Norns that are described as deciding the fates (wyrd) of people.
Verðandi is literally the present tense of the Old Norse verb "verða", "to become", and is commonly translated as "in the making" or "that which is happening/becoming"; it is related to the Dutch word worden and the German word werden, both meaning "to become".
In the anime Steins;Gate, Rintaro Okabe used the term Operation Verdandi to describe the plan to transfer memories into the past, creating a data based time travel instead of physical based time travel. The name references the Verðandi's association with fate.
