Urðr is one of the Norns in Norse mythology, along with Verdandi and Skuld. Out of the three, she represents the past. They are located at the well Urðarbrunnr beneath the world ash tree Yggdrasil of Asgard. They spin threads of life, cut marks in the pole figures and measure people's destinies, which shows the fate of all human beings and gods. Norns are always present when a child is born and decide its fate.
