The Norns of Norse-German-Scandinavian mythology spin the threads of fate at the foot of Yggdrasil, the tree of the world. The Norns introduce the last act of Gotterdammerung, Wagner's fourth opera of the Ring cycle
The Norns (Three Wyrd Sisters) The Yggdrasil tree is tended by the NORNS, who live near it. Each day, they water it with pure water and whiten it with clay from the spring to preserve it. The water falls down to the earth as dew.
n Norse mythology, the World Tree called Yggdrasill runs like a pole through this world and the realms above and below it. Yggdrasill is a great ash tree that connects all living things and all phases of existence.
