The Slovatik Corporation is some sort of Soviet-like mining conglomerate in Killswitch . It is believed that Porto worked for them before the Fires of the Earth destroyed their mine, killing and/or possessing all of the workers and equipment. The director of the mine that Porto was working in created falsified reports of worker malfeasance in order to make up an excuse for the limited amount of coal in the mine; the director's reason for doing this could be varied, but it's likely that he just wanted to keep his job.
Slovatik was known for its controversial methods of obtaining labor - inserting small knives into the joints of its workers as incentive to continue working. Shortly after Slovatik began doing this to workers in Porto's mine, the Fires of the Earth rose up and killed nearly everyone.
