Speak with Trenton Lighthammer at Sandsorrow Watch.
If you're looking for more work, I've got a line for you.
I know an elf by the name of Trenton Lighthammer who's been obsessed with the sand trolls near here for years. He's dead-set on finding some kind of mythical sword made by them, and just a while ago he finally got a crew together to go to Sandsorrow Watch and look for it.
Last I heard, they kicked the trolls out of one of their camps and set up shop there. Look for it to the west, near Zul'Farrak.
