Explore along the path past the depleted ore mine and you will get to a branch where you can head up to High Hall or down to the harbour, each with quests and merchants. There is a merchant along that path you can only meet once, so you may want to wait until you have lots of gold or loot to trade; your runners can get stuff for you to sell, as well as ingredients for the strongest potions you can make, so you can get rid of any lesser potions.
Runners and Tower ?Very low success rate with Fanny Blossom?The anti-dragon shields around High Hall and the harbour can not be lowered, but you should be able to fly high between the shield and mountain to get into the eastern channel (where the third tree is for the seeds quest). You can fly above part of the shield and transform to get to the harbour, or walk/swim there. There shouldn't be another barrier in the eastern channel in DKS (there was in the original release of D2:ED, where 3 ballistas and a nest with a blue lightning effect around them needed to be destroyed to disable the barrier across the channel in the Red Hammer tribe area).
