Also referred to as "the red ground" A red plain where the composition of the oil makes it look like blood. Located on the outskirts of Sedoc, it's a great mortar-shaped depression a mile and a quarter in diameter. It is the destination for a parade of dead bodies that rise from the grave yards and morgues. In all, thousands of corpses from the region leap into the subsidence's thousand-foot drop for two full days. On detecting intruders, the subsistence gives off gas that acts as a smoke screen. At the bottom of the subsidence is an iron door ten feet high and ten feet wide.
