This quest is really not explained at all. All it tells you is go west and it is a new area.
Great I ran West but there is a great big mountain and nowhere to climb it.
So after running around and fighting mobs etc I have now given up.

Great to give us a new area and it is inaccessible? I am all for suspense and working for stuff and not wanting all on a platter, but I am not good with discovering the invincible.
