Ayyo y'all I've just about managed to finish and publish my 3rd chapter of a book called 'Bellflowers.' I'll put the links here and give a bit of an explanation:
'At first, the Vampire Virus appeared in 1 AD. They initially kept to themselves, existing alongside humanity. Vampires built their society in the shape of Human society, instilling the same royal hierarchy as humans. When it came to 1,000 AD, man's increasing prevalence of Religion pushed Vampire numbers, from it's use of reflective metals, specifically silver. Forcing their numbers into scarcity and scorning them in the process. In the 1550s, their numbers slowly start to rise with new places that lack religion. The silver being a weakness, because it has a knock-on effect on their health.'
