The damp smell of coal ash and the sound of hammers filled the night at Black Wind Castle. The stifling air seemed to be suffused with unending coal dregs, causing the Hell Dwarves and goblins passing by to keep their mouths tightly shut, not wanting to say a word.
As night fell, the Magic Crystal Lamp Posts atop the factory gradually extinguished, leaving only the thick smoke spewing from the chimneys rolling across the city's sky.
It's true that the Underworld has some air circulation, but it certainly doesn't compare to the surface. If you want to develop industry here, you inevitably have to pay some price.
But fortunately, for the Hell Dwarves who have long lived near volcanoes, this is nothing. Nor is it anything for the goblins whose product shelf life is not long.
Thanks to their dedication, Black Wind Castle operates like an ever-awake iron giant, unceasingly running in the sunless underground, bringing nightmares and death to the humans on the front lines.
