When someone is killed by a vampire, their corpse becomes a vampire shortly after the last item of inventory (including money) is retrieved from it. They are called a vampire of <name>.
Vampires can kill a new character within one round:
The land is lit up by the eerie light of the full moon. This is a rather quiet and empty street that weaves its way through Escrow. A dark building that reeks of spilt beer stands to the west, while to the east stands a large home nestled in between several others. The street leads off darkly to the north and the south. It is a cool secundus summer's night with almost no wind and some puffy clouds. There are three obvious exits: north, south and west. A slinky girl is standing here. The slinky girl moves aggressively towards you! The slinky girl cuts your right foot into small pieces with her claws. The slinky girl cuts your right leg into small pieces with her claws. Someone says: MY, WE'VE BEEN A BIT CARELESS, HAVEN'T WE? SHALL WE POPPADOM TO THE NEXT DIMENSION?
Killing a vampire turns it into a pile of white ash. In Escrow, when the sun rises, they leave.
