What should I do when I get to Kreug's Room, He keeps asking me to join them. I remember a character mentioning something about him but can't seem to remember what. Any help or spoiler would be nice... Tks

I killed him before the conversation track got very far, just assuming he was a "baddy". He drops a key you need (forgot which one). And his private room is a secret location off the library. Hope that helps.

I tried killing him and not killing him (paying him for the key) and didnt seem to make any difference. He's a baddy so should be fragged anyway

BTW, all conversations are recorded in your journal, so you can always check back there to find out what had been said about someone or something.
