ok i went to the guy in ulgoths beard talked to him, he said he needed the ship records or something if i recall correctally he said to go to the haurbor masters buildings and get chip scudules or something.
one problem-
I CANT FIND IT
i looked all over the harbor masters building and now im stumped give me some help people!

Taran, you really will have to listen more carefully. He said something about getting the map from the Merchant League building, which is just North of the entrance to BG city. I dare say the Harbour Master ought to have some maps, but not the secret one's you need. Good hunting.
