Within the southern empire, there is a rumour. Those rumours tell of mysterious deaths, the corpses bloated and bruised. Witnesses to these deaths tell of unsuspecting victims engaged in normal, everyday activities. Then all of a sudden, the victim gets convulsions and seizures, eyes bulging and mouth foaming. Strangely only the wealthy and powerful ever gets this rare disease.
These deaths are the workings of the Shievren, a witches coven based in the coniferous forest known as the Nebelwald. The witches are approached through the intermediary agent “Grey Dog” in the city of Ur-Kanesh. The witches always require something from the victim, hair, blood and the like. The sages of Yinos believe that these are sewn into their strange puppets and boiled in small ceramic pots they call the Foetherii.
