*sits bolt upright* the natural predator of Vampires is stone circles
why 🤨
Accross Britain (I can't speak for other countries with stone circles and standing stones) an extremely common rejoiner is that these stones in a circle cannot be counted. In some places that simply means that noone will agree on how many there are, in others it means that anyone who counts them will immediately disappear, to god knows were (some say Avalon. I say to some sort of digestion chamber. Wilder men than me will suggest that's two phrases for one concept).
One thing we know about vampires is they are cursed, as part of the condition, with a deep and fundemantal requirement to count things.
Therefore I posit that, much in the way nematodes in soil are naturally preyed upon by fungi who form little mycellial nooses for worms to snag themselves in, vampires are - by force of random brownian motion (vampires cannot share territory and therefore will force each other apart to ensure a wide spread of biters) to encounter stone circles, whereupon they are forced to count them and henceforth be removed from the board. So to speak.
Nematodes:Fungi::Vampires:Stone circles was an absolutely brain breaking take
This also happens with this circle of trees in The House at Pooh Corner. The vampires get stuck forever trying to count the trees. This is why everyone in the Hundred Acre Wood is safe from vampires.
