Undead

No pulse, no breathe, no life, yet still they stir. Dead, but dreaming, they exist to plague the living with thoughts of their own mortality. With tongue-less mouths, they whisper a single name: Nagash. Nagash the Black, first and greatest Necromancer to ever stride the Old World. So great was his fear of what lied beyond the realm of flesh that he was willing to commit any blasphemy, if only he could master death.

From his researches and his rituals arose the Undead. In the Empire, talk of the Restless Dead turns all eyes to the east, towards Sylvania, a cursed land and once the strong hold of the great Von Carstein Vampire Counts who have all, supposedly, been destroyed. There are few that truly believe that, for those that have returned from the grave once can surely do so again.
