It's like an SCP or anomaly of some kind, no one knows where it came from, why it's there, or what it's purpose is. It eats any organic material that comes into contact with it. Anything inorganic ends up simply having the 'flesh' grown over it, taking it over entirely. It acts like an infection made of meat and gore. There are weird shapes, and occasionally teeth can be found in the meat of the fields. Trees grow here, but they're like nothing anyone has ever seen; they too appear to be traps.
