The worl tree - Yggdrasil Picture

In Norse mythology, Yggdrasil (from Old Norse Yggdrasill, pronounced [ˈyɡːˌdrasilː]) is an immense tree that is central in Norse cosmology.
It was said to be the world tree around which the nine worlds existed.
Its name is generally considered to mean "Ygg's (Odin's) horse".

Well for my "Urban Ragnarök" I had to think of how to
keep the world tree an actual tree and still make it work
with our picture of a round globe.
So the idea is, depending on WHERE you are, be it Midgard, Asgard, Niflheim or one of the others) the tree looks different.
So the one you see here is what you see on the humanworld, Midgar. The tree still is giantic, but not as huge.
So how do you get to the other worlds?

Either you go for the rainbow, Bifröst, which leads to the upper branches.
The higher you climb the larger the bridge and the branches become,
untill you reach the top and the branches are big enough to hold Wanaheim, Liusalfheim and Asgard.

Or you take a step inside the roots.
You see the hole within the root
closest to the viewer in the pic?
That actually is a cave, which lies within Yggdrasil.
The wooden tunnels and halls are huge and much like a
You may encounter Niddhoegg,
the dragon lingering within and living from the roots, there.
If you can make your way through, the roots will lead you
right down to Nifflheim, Hel and Svartalfheim.

You may call the size-change and the roots leading to a different world magic
or (which I personally prefer) part of the powers of the tree itself, after all Yggdrasil is a special tree, right?

The three lakes you see resemble the backwaters, mentioned in the myths.
