Frozen In Time

I used to think the world was simple. That everything was easy and life would always move forward no matter what, but boy was I wrong. About one hundred years ago, give or take a decade or two, a war broke out throwing life as we knew it into chaos. Creatures began to crawl out of the shadows. Creatures from myth such as werewolves, shifters, demons warlocks and vampires way too many to name them all. I guess you could say they were tired of hiding in the dark afraid of a torturous death at the hands of humans. Their leaders a ruthless Demon by the name of Dimitri and his vampire mistress Valtoria.
My name is Elva, Elva Lynn Marton, and I'm what you would call a hunter. I am 100% human which now a days is extremely rare. Now here is the information that will throw you for a loop. When you look at me I appear to be around 20 years old and that's because I am, biologically, but I have lived for the equivalent of over one hundred earth years. That is if time were still moving. That's right time has been frozen that means no one ages, no one is born, nothing is moving forward.
