In
Norse Mythology the well in
Asgard which fed one of the roots of the
Yggdrasil. Also near the well in a hall are three
Norns (or Nornir) that tend the well -
Urd,
Verdandi, and
Skuld, personifications of fate. They engrave the fate of all humans onto the trunk of the Yggdrasil and attend to the needs of the tree.
