The lights arrive so fast, Sen can barely keep track of them. Here, they just look like whooshes of a weak flame, speeding to the left as Sen speeds right.
Soon, there are no lights at all. The sun still shines clearly, but the train is now truly in the middle of nowhere. Atop a watery river that should not be able to transport a train, on an electric engine that should have fizzed out from the very beginning.
Out in the water, Sen thinks there is something there. Something else. An island? A pipe? A leftover of an enormous industrial empire, something like Cinder's factory?
But whatever it was, Sen passes it in a second, and won't have the chance to ever pass by again.
Sen's mouth is drawn in a small line. The sounds of rushing water come clearly, yet the train windows remain spotless.
Sen is not worried.
