IMPORTANT MESSAGE TO NEW READERS! PLEASE READ!

My first few chapters' writing quality is very bad and lackluster but gets much better as the novel progresses!

Also, the first 5 chaps are kinda similar to vamp system but the story and settings differentiate after that into their own thing past that point! Hope you stick around! :)

Quick note! many people in the world are cruel and almost psychotic but there is a good narrative reason for that, it will be explained later on in the novel I promise! :D
