The Eye of Kol Korran
This large ship floats near to the coast of Sorrowdusk Isle. The ship acts as a safe zone between Stormreach and the Wilderness adventure area of Sorrowdusk, and allows access to Sorrowdusk Isle as well as return to House Deneith.
There is a barkeep/vendor in the ship that can buy, sell and repair items, and the trader's room acts as an Inn where health and spell points may be regained. A Spirit Binder is located within the ship for binding of your resurrection point, and he also serves as a teleporter back to the House Deneith docks.
If you open your map while aboard The Eye, you can see a nice map of northern Xen'drik, the broader area surrounding Stormreach, with many other quest locations shown.
