The Vampyre Slayer Lineage
Into every generation a slayer is born. One girl in all the world to find the vampires and stop the spread of their evil.
She alone will have the power to fight the vampires, demons, and the forces of darkness. She is The Slayer.
In our time, that girl is Buffy Summers. But Buffy is merely one Slayer in an eternal contiuum of warriors for the Powers That Be.
