There exists a curious legend among the people of South Africa. Although somewhat obscure now, it was prevalent during the late 19th Century colonisation of Africa which saw the construction of railways across the countryside for the transport of workers. This is the legend of the witch trains - ordinary-looking trains, but staffed by the debased servants of a powerful being generally thought to be a witch, or sometimes even thought to be multiple witches. These trains would appear to people travelling alone at night in the countryside and take them aboard, never to be seen again. This was far from the full extent of the machinations of the being that controlled the trains, who will henceforth be referred to as the Witch, but more on that later. Although the activity of the Witch and Her trains has subsided as of late, there is one witch train still roaming, still waiting to return to the Witch's house. Seeking out this train is difficult and will take some time; the rails themselves are not mapped so prepare a rucksack for a long day's journey - and to carry what you will be bringing back. On the first or last day of any month - this is most conducive to the likelihood of the rails appearing - travel by any means to the town of Karasburg in South Africa. When the sun has gone down, begin walking in any direction between north and north-east of the town. It may be advisable to prepare some sort of self-protective gear for travelling the South African countryside at night, but be warned that, once you reach your destination, whatever protective items or weapons you may bring will not be of any use against what you will encounter there. Keep walking until you find a railroad track. Inspect it carefully to ensure that it is not merely an ordinary track. The track you are looking for will be in excellent condition, and if you look closely, the ground beneath the track will be completely undisturbed - there should be no difference between ground beneath the track and nearby uncovered ground. Walk in either direction along the track. It should take no longer than an hour for you to reach the station. In stark contrast to the track, the station is a hovel. You will find the few small buildings completely deserted, and all but one have been burnt to the ground. The one that remains standing is a blackened, rickety, wooden shack, though the single front door appears brand new. A sign nailed to it reads, 'STAFF ONLY.' In older days this station would have actually had staff - the station hadn't been burned, either. The witch trains didn't just stop abducting people of their own volition. The train you are looking for will stop here for you soon, but to make proper use of it you need something from the staff room. No matter what you try, the door will not open for you, but fortunately the Witch gave no special treatment to the walls, trusting them by themselves, along with Her staff, to keep intruders out. They are badly burned and worn. A good kicking at any wall should provide an entrance. The staff room is completely bare, save for a few equipment closets along the walls. Search them thoroughly. Most will contain generic, 19th Century mechanical equipment not worth taking, but one will contain a silver control rod for a gearbox. This control rod will be easy to find - it glows, yet curiously it provides no illumination for anything at all save for itself, no matter how dark the environment is. This is what you need. Take it and wait outside. Now wait, however long it takes. Eventually, you will see the decrepit old passenger train come trundling to a stop in front of you. A train attendant will open the door for you. This train unusually employs both white and black workers, but regardless of his skin colour he will wear an extremely worn and filthy train staff uniform. He will stare at you with decidedly vacant eyes for a moment, and you will very likely feel a sudden, acute sense of discomfort. You would be right to feel this way - the stare is intense, yet there is no-one behind those dull eyes. The man will then say one word
