The Supernatural Revealed20XX.
Only half a decade has passed since the existence of vampires had been revealed to the world after an EU representative was staked on live television. The assassination, spearheaded by a radical international hunter group, sent shock waves through not only human and vampire societies, but those of other supernatural creatures, as well. Tensions are high worldwide as humans warily navigate the world they were once familiar with possessing strange new knowledge that has thrown the supernatural balance into chaos.
It was a literal bloodbath at first, with humans, vampires, and other supernaturals fighting for survival against each other out in the open in third- and second-world countries. First-world countries were not free from the bloodshed, either, but the warfare was usually more discreet, official laws stating that so long as a vampire hadn't been proven to have harmed a human, it was not lawful to kill them (mostly because they were still tax-paying citizens). Communities already prone to strong prejudices found their new vampiric targets easy to blame for any and all societal ills. The situation was so bad in the beginning that if a human were so much as suspected of being a vampire, they could be found dead the next morning with a stake in their heart. Many vampires that held positions of authority were either forced to resign or outright killed by those seeking to keep the bloodsuckers out of their communities.
Blame was not solely to place on humans, however. Various vampire factions tried in vain their own ways to keep their identities secretive, some more violent than others. With humans more wary out in the open than ever, many vampires began engaging in blood trafficking, the kidnapping and selling of humans as personal blood supplies. Others who fancied themselves more moral took to raiding blood banks or blood drive vehicles.
Eventually, the violence slowed as more was understood about vampire kind and their impressive diversity. Several hundred variations of vampires were identified, all with differing abilities and weaknesses. Of course much of this knowledge was leaked to the public through hunter and slayer organizations, although more sympathetic humans took to leading the research efforts into how humans and the supernatural could coexist peacefully.
