Yggdrasil

Yggdrasil is commonly described as an ash tree. This is unlikely as, in the mythology, it is always referred to as an evergreen. A more likely candidate is the evergreen yew tree. Nigel Pennick suggests that an old name for the yew, needle ash, is the source of this confusion. There may ... be a clue in the name Yggdrasil. Schroder interprets this as yew pillar (yggia from igwja = yew, and drasil from dher = support).

Arborea -- the Gnarl in Arvandor is touched by a particularly thick branch of Yggdrasil's crown. There are plenty of other branches here, but this is the best-known, and best served by ratatosk guides.
