Once upon a time, there was a war. Humans verse the supernatural. The humans were stronger than you think; they learnt about the supernatural's weaknesses and quickly exploited it. Many died and many suffered. On the 3rd of July 2020, a plague was released into a small town called the WB47, a mixture of wolfsbane, silver and a bacteria that has been known to cause the flu. Alone, they aren't that dangerous but together they were deadly. In that town it spread quickly, the virus going undetected by symptoms included internal bleeding and coughing. Everyone died except one, a little girl we know as silver and she's the cure.
