Horker Island is a Location in The Elder Scrolls V: Skyrim - Dragonborn
This small island is found just off the coast of Solstheim. You will encounter a number of Horkers on visits. If you are here looking for the pirates for the Deathbrand equipment, then you will find Reavers here instead of Horkers. The most dangerous of the Horkers will be a unique one named Lord Tusk.
You will also find the entrance to Gyldenhul Barrow on the Northwestern side of this small island.
