It might sound like a silly question but I am on Chapter 4 of the Original Campaign and was just about to enter the Source Stone dungeon to meet Morag. I could not kill the left hand and have not played it since a couple of months in which time I forgot where to get my henchmen now. I tried the trade of blades and the temple but no cigar. Where are they hiding and how do I get to them?

If I'm not mistaken you cannot get henchmen in chapter 4 but are stuck with whatever you got from chapter 3.
