Slugfest

During the drow quest when you go looking for the three dragon teeth, the entrance to the bronze dragon layer on the west side of the map held only a single gnoll, no dragon!  What is the item code for the bronze dragon tooth?  I would love to fight the dragon but by all accounts you get no XP for it anyway....  

Well I happened to notice that other users have been unable to to "end" the final quest in TDD.  I am about to exit the underdark and tackle the other quests/new areas in this mod but now I have to wonder: will I be able to segway right into ToB with my party intact after defeating Irenicus if I want to/is there an option to decline the main TDD quest after Irenicus is defeated if you cannot segway into ToB afterwards?  In otherwords, if you can't take that extra xp with you into ToB that you gather from doing the quests in TDD then what's the point of the mod other than just trying something different?     

I currently have TDD, Tashia, and the Solufien mod installed and I would REALLY like to take Tashia and Sol with me into ToB again, romance and all.
