“In the middle of Asgard, where the gods lived, was Yggdrasil. Yggdrasil was the tree of life. It was an eternal green Ash tree; its branches stretched out over all of the nine worlds, and extended up and above the heavens. Yggdrasil was carried by three enormous roots.
The first root from Yggdrasil went to Asgard, the home of the gods. By this root was a well named Urd’s well. This was where the gods held daily meetings.
The second root from Yggdrasil went down to Jotunheim, the land of the giants, by this root was Mimir’s well.
The third root from Yggdrasil went down to Niflheim, close to the well Hvergelmir. It was here the dragon Nidhug gnawed on one of Yggdrasils roots. Nidhug was also known to suck the blood out of the dead bodies.”
