Yggdrasil, also known as the World Tree or Tree of Life and Death, is an immense cosmic ash-tree that serves as the home of the Nine Realms 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.

Description

The Yggdrasil is a massive yew tree that grows out of the Lake of Nine, believed to be the center of the Norse cosmos, its branches interconnect the various worlds, also known as the Nine Realms. The tree and the Lake of Nine, display a great physical presence, but also an ethereal connection to one another. In the realm travel room, the brim of the well includes a sculptural depiction of all the different realms and its connection to the tree that travels between them.

On the base of the pedestal, we can see three owl-like figures with the central figure being Urð; in their talons, the bluish shape represents the Bifröst, carried by the gods and used to travel between realms. The tree itself exists in the Realm between Realms. Within the realms, the tree has multiple utilities. Collecting dew from its branches (which can be found near bodies of water) will provide permanent stat upgrades. Additionally, crystallized Yggdrasil sap is a powerful conductor of electricity: hitting it with any electricity will create an explosion.

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.
