So yeah. Vampirella and Purgatori. Vampi, the Vampiri with a conscience and Tori, the lady-shaped creature who eats conscience. Working together? Not really. Working towards a common goal, while considering tearing each other's throats out, more like!
And that common goal is to stop Lilith and her near-infinite minions from having their rough, rude way with the entire human race. The stakes are big enough... and sharp enough. Everybody's in... it's time to ante up.
