That is a unsafe trip to take alone, even for an Orc. After all those are some high mountains full of dangers, and scaling them all alone is next to suicidal. Going south to join a group of adventurers would be much smarter. You could have him already in the Low Orclands and heading for Fort Ligura. It would be a more sound decision then scaling the mountains as well as a chance to incorporate as much of our characters into groups.

Except for Kaymari, Sear and Ayya most of southern Lemea is unsafe to extremely dangerous, so dangerous that even a experienced adventurer and traveler like Aerrea is not foolish enough to travel trough it alone.
