Ater I speak with the inn keeper, how do I protect him from the Cowled Wizard Mercenaries afetrwards? Oh yea, and I heard from that I can get Vesine of TDD there, where is she and how do I get her?

I think that you speak of the inn on the lake?
Get out of inn, go to the dry land. Mercs are somewhere around. Not hard to find.
IIRC, she is in the inn. Five centimeters from the innkeeper.

where is Small Tooth Pass ? Is it that pointless bridge map when you return from the underdark ? I've heard of it but I dunno where it is. Also, this inn by a lake ... where the hell is there an inn by any lake ? where the hell is there a lake !?! is this a TDD question ?

This is a TDD question.
