Welcome to the esteemed Layer 4 of the Parmesan Geological Profile, where the earth's crust has been thoroughly... well, not thoroughly, but moderately scratched.
Here, you'll find the remnants of a bygone era, when the Parmesan cheese wheel was still young and full of life. Now, it's just a fossilized memory, with cracks and fissures that tell the tale of its storied past.
Proceed to Layer 5, where the cheese has been reduced to a mere shadow of its former self.
