Along the eastern coasts of Pipe Home lies a lengthy reef known as the Teeth of Aerdresh. The foundation of this reef comprises the skeletal remains of Aerdresh.
The few secure routes from Salzârrâk to the inner lagoons and coastlines of Pipe Home are vigilantly guarded by the naval forces of Pipe Home's city-states. The immense depth and expanse of the reef serve as the primary defensive barrier for the island strongholds of Pipe Home.
The expansive nature of the reef and the adjacent isles resulted in the greatest concentration of lighthouses per square mile along any coastline.
