This graveyard isn't full of death plots in the classic sense. It is a vampire graveyard, after all. Despite their feral nature, vampires nevertheless have a strong sense of brotherhood and loyalty to the clan.
It is in this graveyard that the ashes of vampires who have passed are spread. Dracula generally leads an ash-spreading ceremony, and headstones are erected in memory of those passed on. And the name of the place? The first Vampire to ever have his ashes spread here was named John.
