The world doesn't end with a crack.
It ends with a wet, sucking sound.
Not in fire. In rot.
It doesn't collapse - it festers.
And in that decay -

The Pit.

A sealed, sepulchral, sacred-in-its-filth prison - into which the centuries have thrown everything that doesn't fit the order: heretics, witches, soldiers who lost their wars, women who spoke too loudly, and men who spoke in the wrong voice.

But sometimes...

...the Pit receives the Great.
