Unknown NPC named Korrilla shows up after backtracking to defiled temple. You can't interact with her and if you attack her she disappears without taking damage.
I googled for this NPC and I guess this one is used when you get imprisoned by the goblins and helps you to get free? But in my case she shouldn't show up, because I already killed everything there and already was at the grymforge
I saw her randomly after backtracking so I don't know if she is always there or something triggered her to appear. (I just can remember that she wasn't there when I played patch #8)
