Destroy the flying machine at Bael Modan and return to Gann Stonespire.
Following Khazgorm's plans it should be no problem to fashion an explosive charge
Ah, there we go.
Now, [player], I am going to entrust you with a special task. Take this explosive stick and use it to blow up the flying machine at Bael Modan.
Not only is the flying machine a key part of the site's infrastructure it also serves as a weapon of war. More importantly it is an icon of power and an insult to the memory of my tribe.
Make me proud by completing this heroic task and you shall be rewarded.
