The train thundered across the dark snow plain, its headlight the only source of light in the world. Ice and snow covered all traces of life, with only the occasional remnants of broken walls peeking out, like islands of civilization left behind in this dark world. As the train roared past these ruins, the heat it generated would briefly gasify the surrounding snow and ice, turning it into a gust of wind.
Ybur was perched on the roof, spreading his tentacles out, tightly grasping the sheet metal on top of the train. The air was so thin, almost a vacuum, that despite the train's high speed, he wasn't worried about being blown off by the wind.
Looking outward, the star tracks extended endlessly forward, as if stretching to the end of the world.
Occasionally, some elemental creatures living on the snow plain would get disturbed, like moving glaciers.
