Until recently, the engines hauling souls back and forth from the Gravestar were seen as being controlled by some dark and terrible master (or masters). The truth is that the Skull Trains are those dark and terrible masters.

They stretch out across the skyline, six miles long and fabricated from black steel and malevolent intentions. Grinning mouths, pinpoint-killer eye sockets and corpse-cutter teeth. The trains keep their own time, rollin' along, endless and omnipresent.

Skull Train hisses, steam billows out in foul-smelling coils.

* FOOLS. ALL FOOLS. HOW DARE THEY OPPOSE OUR MIGHT? OUR RULE IS ETERNAL. *

The corpse-cutters gnash and grind. The sockets shine with fierce red light.

* FOOLS. AWAY WITH YOU ALL. *

The supplicants lay across the track and the Skull Train proceeds, crushing them all beneath its wheels.

Freedom.
