The path at the south-east side of the crash site area
After checking out the stone (and discussing it with Virgil if he's in your party), you should follow the passage between the mountains. You will encounter a mysterious-looking man who starts asking you about the crash. It is clear that this guy is bad news, so you can do one of these three things:
- Kill him
- Let Virgil talk you a way past him (Virgil will interrupt the conversation)
- Sneak past him
After dealing with the man one way or another, continue your way. The world map icon will light up in the top left of the screen, and you will be able to use it to go to Shrouded Hills. I recommend you do this, as there are some nasty wolves further on that will make quick work of your low-level character.
