Deep Blight

The Deep Blight is a set of phenomena that have been happening along the northern coast of Erde for the past 800 years. In the 80 years following the first civil war of Erde, there were increasingly common reports of ships and expedition parties going missing along the northern coast. By the year 750, choking algae completely hindered exploration by sea, and a thick, putrid-smelling undergrowth made travel into the area by foot impossible. Aerial expeditions have been mounted, but the thick sea fog of the region, and unexplained magnetic anomalies that interfere with navigation equipment has made these expeditions relatively fruitless.
