You are all free to leave Alband now, and this chapter will end once the party decides on its next destination. You could hang around here, but I wouldn't recommend it.
1. Continue north, on horse, to the orcish fortress where Gorham is supposedly hiding out with Martjan. You've lost Aeron's relief map, but several of you got a good enough look at it that you could conceivably find your way there.
2. Backtrack to the crossroads and head to Solyhill, where Gethro is investigating the dragon (?) attack that killed the Hazard Army cohort.
3. Head east to Sthombo to scout out the place where the Iron Sphere may be hidden, to see if Gorham really found it or not.
You could also head back to Hazard to search for clues there, venture down to the Gaad/Gurmar region to look for Zora, or come up with some other brilliant plan. Whatever you choose, Annganne will meet up with you when chapter 7 begins. What do you think, party?
