For as long as the humans have existed, so have the vampires. For as long as vampires have existed, so have the Slayers. The coexistence of these three groups has survived thousands of years of war, fear, and destruction. Today isn't any different. The year is 2023, and it's been eleven years since the existence of vampires and Slayers became global knowledge. A constant night has fallen since that time, throwing the world into dark chaos. The life on the planet is beginning to wither slowly without the life-giving rays of the sun, and only the moon provides the Earth's surface with glow. The humans remain as neutral as possible while the other two groups continue to wage war, and in the process they are forgetting about more necessary priorities. The world will find its end soon if the someone doesn't bring back the sun, and that would be a fate that neither side could escape.
