Escape from the Dark and Into the Black (слэш)

Harry and Severus disappeared after they defeated Voldemort. They reappear 500 years later on Malcolm Reynolds' ship, Serenity, much to the surprise of all parties. No one knows what it means except that it is yet another job the Serenity crew might not get paid for. You don't need to be familiar with Firefly to understand this as I've tried to explain what needs to be explained. Snarry, One-sided Harry/Mal, Jayne...let's not talk about Jayne. Also warnings for bad Czech acccents and probably incorrect Chinese translations. This is complete.
