In a place where there was no light, window, or door, many people lived there. They share beds, food, and drinks.
They had been hiding here for three years, and their young children had never seen the sun or the beauty of the plants.
This place was not in a tower, nor was it in prison. They didn't have a house… they had it but couldn't stay in it.
This place was below ground, about a hundred kilometers from the surface, with only one entrance and exit.
Why do they live here? That was because the above situation made it impossible for any living being to survive. Their world was filled with black miasma and could only send a few people who were brave and willing to die to see the situation above or look for something to eat.
Of course, they wouldn't find anything up there, but sometimes they would find carcasses they could formulate to make their own meal.
