Greenmouth Plague

From Brass Goggles

Greenmouth Catatonia, a disease that has begun to appear in many places around the world Since the removal of the Golden Tablet of the Plagues from the ruin-mound of the ancient Babylonian city of Cutha, legendarily the seat of the Plague God Nirgal, Lord of the Underworld. This disease is currently known to have four stages of infection and is most likely passed from person to person via parasites in the mouth.
