Where to next?

[Kammy]

I am in chapter 3. But have done all of the quests I have come across, except I have not finished killing off old Fried, whatever his name. So where to next? Jaheira left the party to go do some harper thing. So I am wandering around trying to find things.

In the sewers there is that secret room. I have the key, and have gone in there...was pretty ugly, but is that a particular quest? I am still trying to get Iomen, but I have no clue where to go next.

Any help would be appreciated. I know I am overlooking something, but hey...that how life is...

Thanks a bunch.

First wait until Jaheira comes back (ithink she will come when you rest) cause she will start another little quest. Second, there isnt any quest in the mindflayer dungeon in the sewers so you can just enter and kill everything here (though its not that easy).
To rescue Imoen, you should go to the thieves guild in the docks and talk with Aran Linvail. He will ask you to do some subquests and then you can go to rescue Imoen.
