Eye Rot

This strange disease is believed to originate from the steaming jungles of Lustria, brought back to the Old World in the fifteenth century. Rare now, it seems to be spread by the touch of Plague Bearers alone. When a victim catches Eye Rot, he experiences painful headaches as fluid fills his eyeballs, causing them to bulge and shudder in their sockets. Many of the afflicted pierce their eyes with knives to ease the pain, spraying the diseased fluid in all directions.
