Northeast of Bal Fell is a a rich talking Mudcrab. He is directly across from Releth Ancaestral Tomb. He has 10,000 gp and buys items full price (unless they are broken).
He will buy most items. If you manage to find him and you have a spell called Mark use it there. If you Mark it, you can cast a spell called Recall to warp there. Do not kill him. You will need him after you get farther in the game and need someone to sell items to.
