[Laezyre]

I can not get into the elven mines despite trying everything I can think of. I befriended the elves, destroyed the evil book and talked to Kael-Shot afterwards. The king's castle is empty. Iron Richard's castle is empty. I have talked to the mage in the tower and watched his tower for him. I have talked to Eric after the first fight with the evil prince. Nobody has a new lead or quest for me.
Is my game bugged?
