DISCLAIMER: In an effort to make interactions easier, and so I don’t have to come up with a completely separate verse, this is my attempt at melding Twilight and The Vampire Diaries canon together into a somewhat comprehensible and cohesive narrative. Mind you, I have not watched The Vampire Diaries all the way through, nor have I seen The Originals, so I may have gotten some information wrong here ( in which case, let me know and I’ll fix it! ). It’s still messy and it probably doesn’t make a whole lot of sense because it’s late here, but this is basically what I’ll be assuming when I interact with TVD characters. You are by no means obligated to follow this! And if you would like to discuss other options, please don’t hesitate to let me know. * do not reblog.
There are two main vampire lines. The first line—and the line that Jane and others like her descend from—begins with the First Vampire, Lilith; the blood-sucking she-demon whom was originally reported across several different religious texts to be Adam’s first wife. Yes, that Lilith. Lilith was originally created alongside Adam in God’s image, to be Adam’s equal. However, when Adam tried to subdue her, she fled and refused to return to him even at the pleading of Angels. Instead, she chose to become the wife of a demon and in doing so became a demon herself ( There are many many different versions of this, and I would be here all day if I tried to break down the origins of Lilith but that’s not the point of this post so just bear with me ). Thus, Lilith became the First Vampire and the progenitor of the line of vampires that we would find familiar in The Twilight Saga. They are the first and oldest vampire race, attributing to their unique makeup and special abilities.
The second vampire line begins with the Mikaelsons; the Originals, as they call themselves. While they are not the original, first vampires to walk the Earth, they are original in the sense of how they became vampires. The Mikaelsons became what they are through the Immortality Spell. A witch’s spell, and thus all vampires we’re familiar with in The Vampire Diaries were created from them.
These two lines exist in tandem and co-exist together, but not always peacefully. For all intents and purposes, the Volturi still exists and sees themselves as the “leaders” of the vampire world; the ones who set down the laws and uphold them. They play judge, jury, and executioner to those that would break the laws they set forth to protect the secrecy of their race.
Because the Mikaelsons, and those created by them, were essentially created through a witch’s spell, there exists some tension between the two lines. Much older vampires, like the Volturi Masters, for example, find them to be inferior and not “true” vampires, as they can be killed much easier and, if in possession of the Cure, can become human again if they so wished.
Despite this, there is certainly no denying that the Mikaelsons, and those created by them, pique the Volturi Masters’ interest. Aro, in particular, and in typical Aro fashion, is always looking for a unique stand-out to add to his collection; and this is perhaps the only reason why action has never been taken to rid the world of a second vampire line. At least, not yet.
