The Nine Worlds rest within the World Tree. Our deeds, and the deeds of many flow down the tree to its roots.
The tree supports us, and our deeds water the tree. We are one.
Voluspa - Norse Mythology Book - Verse 19
“An ash I know, Yggdrasil its name,
With water white is the great tree wet;
Thence come the dews that fall in the dales,
Green by Urth’s well does it ever grow.”
