Editing World Tree (section)

=Planescape and Core D&D=
In the 2E [[Planescape]] setting, Yggdrasil ''(along with Mount Olympus)'' existed alongside everything else and is an actual ash tree that was used as a means of multi-dimensional travel. It had its roots in [[Ysgard]] but grew onto and through other realms; allowing travelers to literally climb the tree and pass from world to world.

Since the Asgardian Pantheon also existed in 3rd edition, so did a separate variant of the World Tree cosmology, which probably mirrors the Norse version the most:
The World Tree has its branches in '''Asgard''', while its roots extend down into the three realms:
*'''Asgard:''' where the root of the tree touches the ''Well of Urd'' and is tended by the Norns of Fate. Asgard is home to the '''Aesir''' ''(Gods of War and Destiny)'' and the '''Vanir''' ''(Gods of Wisdom and Prosperity)'', it is also the location of '''Alfheim'''  ''(for the Elves)''.
*'''Migard:''' where the root of the tree touches the ''Well of Mimir'', the source of wisdom. Midgard consists of the mortal realms '''Mannheim''' ''(for humans)'', '''Jotunheim''' ''(for Frost Giants)'', '''Muspelheim''' ''(for Fire Giants)'', '''Nidavellir''' ''(for Dwarves)'' and '''Svartalfheim''' ''(for Dark Elves)''
*'''Niflheim:''' where the root touches the river ''Hvergelmir'' which is the source of the world's creation. This is the land of ''Hel'', and is where everyone who dies of sickness, old age, or accident go.
