Hi Felix,
Not so much of a crowd around here.
Well, that's quite an end of the world that you've depicted.
I like the way you started it which makes me think about "I had a dream".
Questionned about punctuation's choices that I find somewhat irrelevant, such as :
"The soil was harsh ground, and the whole air..."
"Their skin was ripped, and slashed"
"in the last, of men’s fire"
Also, I'm not sure about the emphasis on the emotion here. I mean, it's clear without saying that the narrator may be terrified by his nightmare, it is the all concept of a nightmare. So, sentences like "It was terrifying" or "I didn’t want to face them, they scared me, I felt threatened by their only presence" are, to me, unecessary in this context.
Otherwise, I like the chaos, the set of sensations to describe it. Pictures nicely written.
Also, I was wondering about the change of point of view.
The first paragraph could be the narrator's impressions of the surroundings, what he sees, how it impacts him. However, in the following paragraph, he has kind of a global vision on an entire continent. It sounds weird, not related to his own experience, as if he knew this thing from a long time ago. To me, something switches too drastically between those two paragraphs.
