Yggdrasil

Yggdrasil (pronounced "YIG-drah-zill"), also known as the World Tree, is an immense cosmic ash-tree that serves as the home of the Nine Worlds and a means of travel between them. Yggdrasil's branches extend far into the heavens, and the tree is supported by three roots that extend far away into other locations. Various creatures live in Yggdrasil's branches.
== History ==
=== Creation ===
It is not specified how exactly Yggdrasil came into existence, but it arrived with the Nine Worlds' creation, after Ymir's death.
== Appearance ==
in The Sword of Summer, Magnus described Yggdrasil's smallest branches being as large as an average redwood, while the biggest ones being wider than Interstate 93. As for the tree's trunk, it is so immense, that it just didn’t compute with Magnus. Each crevice in its surface seems to lead to a different one of the Nine Worlds , "as if someone had wrapped tree bark around a column of television monitors glowing with a million different movies."
Beyond the tree’s canopy nothing but a hazy white glow of the primordial Ginnungagap mist can be seen. No ground can be seen below either, only more branches crisscrossing the void.
== The Nine Worlds ==
* Midgard - The world of humanity.
* Asgard - Home of the Aesir tribe of gods and goddesses.
* Vanaheim - Home to the Vanir tribe of gods and goddesses.
* Jotunheim - Home to the jötnar.

* Muspellheim - Primordial world of fire and home to the fire jötnar.
* Alfheim - World of the Elves.
* Nidavellir - World of the Dwarves.

== Trivia ==
* Yggdrasil's roots extend into three locations:
** Urðarbrunnr (ON: “Well of Urðr”), Hvergemir (ONr: “bubbling" or "boiling spring”), and Mímisbrunnr (ON: “Well of Mímir”). As seen in the Poetic Edda poem, Grímnismál, various creatures dwell within the World Tree, including:
** Níðhöggr, a massive dragon/serpentine creature that gnaws at its roots, an unnamed eagle, the hawk Veðrfölnir, who sits between the eagle's eyes, and the four stags Dáinn, Dvalinn, Duneyrr, and Duraþrór.
* The three Norns - Urðr (ON: “fate”), Verðandi (ON: possibly “happening” or “present”), and Skuld (ON: possibly “debt” or “future”) - attend to Yggdrasil, weaving the fates of both gods and men.
* The Maya have their own world tree called Ceiba (pronounced "SAY-bah").
* The Hindu counterpart of Yggdrasil is Kalpavriksha, the tree from the Ocean of Milk that grants wishes.
* The story of Jack and the Beanstalk was inspired by Yggdrasil.
