“The only residents remaining in the small town of Miners Hill are spirits.”
The mine collapse killed several bodies, and the living ones left with their broken families from the broken economy. Without the mine, they didn’t have money to rescue the workers, and Miners Hill became a ghost town.
The ghosts of the miners still work the mine. They work without any rest in hopes things will go back to normal. They work every second of every day so their families have a reason to come back. The hopeless ones are the hopeful ones, and the ones that gave up are gone. To live in the shadow of a murderous hill was too dark for the people outside, but the men who are trapped in eternal darkness stay to work: work to get their families back, or work to get back to their families. They’ve almost dug back up to the surface, out of their collective grave.
