Vampires are one of the most dangerous creatures within the multiverse and not for the reasons you think.  I mean they are super strong blood sucking life draining monstrosities who are really hard to kill, that is a problem, but that is equally true for most undead.  No, the great problem of Vampires is that there are so many species and version of them that any given hunter will have no idea what exactly will work.  Many an adventurer has attempted to tackle a bloodsucker only to find their life force drained in the process.  Or upon seeing a fanged monstrosity, casting a healing spell and watched in horror as he healed his enemy.  There are a dozen different creatures who claim the name vampire and all operate in fundamental different ways.  Why there are so many creatures who fit roughly the same theme is a matter of great debate among Planar Scholars, but the rough consensus is that it is Dragons fault, because Dragons are dicks and they would totally do something bullshit like this.  Clearly bloodsucking creatures how reproduce through biting and taking over the parasite is entrenched deeply into the collective subconscious that people’s belief keeps making newer and worse versions of these horrors.  This is why Vampire Hunters are in such great demand, because it requires a great deal of expertise to know the difference between each creature and how one might combat it.  

A few constants do emerge

They Drink Blood except when they don’t 

They have fangs which they can hide except when they can’t (Nosferatu) 

They are undead except when they aren’t (Opir/Vamps)

They are souless except when they aren’t (Cainites)

They are extremely vulnerable to fire except when they aren’t 

They don’t like wooden stakes except when they do 

This information is usually kept obscure by vampire hunters as their services are more valuable if people know less, but at the risk of angering the guild, I am going to just give this primer for you all, after all public safety is the first concern of us all, far more than such fragile things as ego and contract negotiations.  The follow document will study all of the types of vampires so you can defend yourself from the creatures-Eilina
