Thank you, got it!! :-D Now if only I could get someone to be as precise about the yardbird in Mirkholm Keep, I'd be happy!!
Actually there are two yardbirds in Mirkholm Keep:
First - In the cave system where you go to fight Munin...When you enter that cave system, stay to the wall along the right hand side. There are three small rooms/caves in there. Go to the last room/cave. It has some tables and food and shelves in it. The yardbird is standing at the back wall of that room. It is VERY hard to see it.
Second - In a VERY SMALL alcove in the very middle of the whole cave system that Kerkir is in...Look at your map. It is the small alcove exactly between Herkir and Hyglak Shadowstalker in the middle of your picture of your map (near the Grendel Wortlings).
