Iron Rocks is where the Iron Sails have their hideout. Thebarren islands are made of an iron rich mineral that prevents anything from growing on the islands and only a few sea birds and sea mammals live there. Underwater rocks and reefs, which makes sailing in the area dangerous, surround the Iron rocks. Hence, the sea is filled with sunken ships, some more than two-hundred years old. To maneuver the dangerous waters, one have to have an indepth knowledge of the sea and of what lies beneath the surface. The Iron Sails have made the extra precaution of iron-reinforcing their hulls to prevent the underwater rocks and reefs from carving up their ships.
