Vampires

The modern day term "vampire" most likely derived from Slavic origins. The Serbian word "vampir" was incorporated into the German language, then to the French as "vampyre" and finally into the English "vampire." These undead horrors have various abilities and powers depending on folklore and place of origin; literature and cinema have also had a lot of influence on the vampire image. According to Eastern European folklore, the dead become vampires because demons or evil spirits enter the bodies. Vampires are also said to be dead werewolves, witches, criminals, suicides, and heretics: persons whose beliefs are contrary to the church doctrine. Again, sources vary, but a victim of the vampire's bite typically rises again as a vampire after dying.
Vampires often possess higher physical strength, dexterity and sharper senses than their mortal prey. Some may have the ability to take the form of a bat, wolf, rat or mist/smoke. The vampire can influence some animals - typically wolves, bats and rats. They can scale vertical surfaces and can use an uncanny hold on a victim through their mesmeric gaze. If a vampire has a masterly hold on a human victim, it may be using said victim over a period time as a constant source of nourishment.
Weaknesses include silver and sometimes iron which will cause the vampire pain. Similarly in some traditions, the wood of the hawthorn tree, which has Biblical roots, will also harm a vampire. Holy religious symbols can be used to hold the creatures at bay. Vampires also seem intolerant to garlic. Vampires, being nocturnal beasts, cannot function in sunlight; indeed, exposure is fatal in most folklore and adaptations. Some vampires cannot cross running water, and most can only enter a property if personally invited inside.
Burying a victim face down or placing poppy seeds in the grave of the deceased will, according to legend, prevent the resulting vampire from rising.
If nosferatu can be tracked down to its lair, generally the place they where buried - a tomb, grave, mausoleum, or even family estate - they can be disposed of traditionally with a wooden stake through the heart. Severing the head will assure destruction.
After The Convergence, many worlds became one, meaning several different strains of vampirism exist.. moreso than there were in any individual worlds before. Demonic vampires from the Hellmouth, vampires cursed by God, descended from Cain, and ancient vampires born from the Darkhold and the power of the Elder Gods all coexist. Their secret societies at odds with each others, the only thing having so far stopped an outright war is their need to stay hidden from the general public. There is no official Masquerade in place, but in a world where vampires now have to worry about Superheroes on top of regular Hunters, not exposing themselves is the best way to make sure they don't get the attention of the Slayer, the Daywalker.. or Superman.
