Urd (Urðr) is from the Old Norse urðr (fate, that which has become). **Eldest of the three Norns** — the Norse goddesses of fate — **representing the past, what has been**. **Her well, the Well of Urd at the foot of Yggdrasil, is the source of all destiny.**
Featured in the Poetic Edda and Prose Edda.
Urd reduces to three — the number of Norse past.
