On the surface, Lima seems like a perfectly normal place. Perhaps the death rate is a bit higher than other places, and the number of graveyards seems excessive for a town of this size, but for the most part, it seems like an approximation of small-town America.

Of course, that's because most people don't realize what lurks beneath Lima's surface. Hidden under McKinley High School lies a portal to other dimensions known to many as the Hellmouth. Its power is like a beacon to supernatural beings all over the world, all keen on feeding on the Hellmouth's power or else just settling in for the long-run.

It would make sense, then, that the Slayer has emerged in this past year as a student at McKinley. There aren't many people who can identify her on sight, but rumors abound that for the first time, she's not operating on a solo basis. It'd be quite the catch for someone to shut her little operation down and leave Lima free to less benign forces once again. There's only so much a vampire can stand to deal with, after all.
