They will work to pay off their debt to the company and earn their freedom, but must contend with the dangers, and wonders, that they encounter in these extraordinary mines.At a crumbling, ruined chapel that shall be their new base of operations, the miners are greeted by a mysterious person who claims to be a Company veteran. Foul, feral, and secretive though he may be; the miners will decide how much trust can they put in their new guide who tells them that he is officially dead, off the grid, and desires retribution on the Company that sent him there. The miners' time in the huge network of mining caves shall bring them to face otherworldly forces and malevolent entities. While not natural fighters, they must use their resourcefulness to overcome the dilemmas that they encounter. All the while, they must deal with the supernatural residents of the caves; entities from English folklore who were thought lost to the world, and other interests who stake their claim on the mines.
