Path

First, we need to head to the Fields of Glory near the city of Carlin. Dig the hole marked below and descend:

Move south, killing wolves along the way, and go down the ladder:

Head east (encountering some trolls along the way):

Next, in the overgrown green area, look for a hidden hole and switch the lever to the right:

Now, follow the map north. You will have to cross a few energy fields, behind which there should be a hole. If the hole is not there, it means that the switch was not previously set to the right position.
