(Conquest, System, no special powers. Whether there’s a harem depends on what readers choose later.) Unlike most stories set in the Dark Zone, this one only borrows its general worldbuilding. Of course, you can still enjoy it even if you don’t know the Dark Zone setting. If you find that some events differ from the official story, don’t argue about it. The Dark Zone’s backstory is constantly being updated, and the official version may not have covered a plot point yet when I wrote it. (This is my first book as a new author, and I’ll do my best to finish it.)
