I'm using Ghorbash Iron-Hand as my follower and the bastard is lost. I told him to wait for me at the Imperial Camp in the Pale, but he's no where to be seen when I went back. I go to Dushnikh Yal, just in case, and he's not there either! Where is he and how do I get him back?

Are you on the PC? Use "moveto 00013B81" in the console to teleport to his location. Or, you could use "placeatme 00013B81" if you want him to just teleport to you. Might be more interesting to see where he's gotten to, though. If you're on a console? Might have to say tough luck. I don't know of any way to find lost followers.
