What a honour to answer a question of CB's leaderbossman !
Had to think awhile if it was the one, since I had to translate it back from German, but yes, I am almost certain is was that one. In think the next event/dialogue was triggered when I was back - for that purpose only - in the Something Pass map area (Great Fang Pass ?) in the south. The one to which virtually no quest is related. But I think any of the four areas in the southwestern section of the world map will do: underdark exit, the one mentioned above, the Northern Forest? and Tethyr Forest, since they all require CD No. 4.
Good luck !
