I think I killed Conster too fast. Garren's child just keeps telling me to go and kill the mage and rescue her...
I thought I would clua him in then kill him again to see i that helps.
Edit, I just offed Fiirkrag himself, still no luck, she still tells me to go and kill the mage. The door is open, so she could just leave, but she refuses to move or talk sense...
Edit 2 SK-ing the key in then talking to her helped.
In nearinfinity he is called FIRMAG01.CRE Idk if that is the clua command though. I was looking for a list I used when cluaing Saemon Havarian but couldn't find it again.
