I had this thought about another of Vivz's storytelling flaw. She has set up this whole universe where there is this very specific vision of Hell where you have souls of the people from the living world, but also various being native to Hell, you have the nine rings of Hell, and you have something resembling the human society in Hell.
But how does all of that work? Is there some kind of government structure? Are there any laws? Are there some traditions, customs? For example Loona's backstory. Under what circumstances was she born, and under which circumstances she landed in the kennel? Did her parents leave her straight after birth because that's how hellhounds act? Did she lost them at a young age? And also, when a hell being dies, or even a human soul, what happens to them? Do they get sent to some other realm? Do they get stuck in a limbo? Do they cease to exist? What's the deal with this interpretation of the rings of Hell? How does that work?
There's so much basis of world building laid out, yet she doesn't bother to elaborate on any of those, they're just there and that's it, and the entire focus of the series is her projecting her daddy issues on characters like Stolas. She came up with a good basic idea, never bothered to expand it, and got stuck in a perpetual loop of a Tumblr fanfic.
