I must say, I've finally understood Yggdrasill's nickname. Now I wonder how I should pronounce it...
I guess you have to pronounce it in Norwegian, or perhaps more like they speak in Iceland.
You have to be careful with the sound of R and I.
R is a rolling R, like you are going trough an electric shock and got to little to drink the last six days.
The I is like the sound of an pretty lady who get lost from a travelparty, and panicking in the heart of Amazonas.
Like Yggdrrrrrrrrrrrrasilll
