Facts About The Story.
These are the facts, that you should have known from the T.V shows.
The following just happened in the T.V show. I've written this chapter for the people who haven't watched the show. But don't worry. You can still read this story even if you don't have any knowledge about the canon.
This is a fanfic, so it will not follow the canon, and most of these events will not take place in this story, but this chapter gives you some common knowledge about the world of vampire diaries.

-------Immortality Spell.
The Immortality Spell was originally created by a witch named Qetsiyah, in 1st century B.C. The Mikaelson family story took place one thousand years later, in 1001 A.D.
.
It is an extremely powerful spell used to transform a mortal person, into an immortal creature. There were four kinds of immortal creatures on the TV show - True immortal, an Original vampire, an Enhanced Original vampire, or an Upgraded Original vampire.

-------Doppelgängers.
Doppelgängers, also known as Shadow-Selves, are a supernatural occurrence that were created by Nature as a result of Silas and Amara becoming true immortals after consuming Qetsiyah's immortality elixir. The purpose of this supernatural species is to maintain the natural balance by dying in place of their immortal progenitors. For this reason, doppelgängers have existed for thousands of years, during which time, they have been born and died in place of Silas and Amara.

The Immortality spell was used four times in the T.V show.--

-------1st century B.C - Silas and Amara - (True Immortals).
True Immortals are a species of supernatural beings that are truly immortal and cannot be killed by any weapon. The term "immortal" is used to describe the species into which Silas and Amara, the very first immortal beings in history, were transformed when they consumed the immortality elixir created by the witch Qetsiyah.

The Original vampires, are a group of extremely powerful vampires that are known for being the progenitor of their bloodlines, which makes them the oldest, fastest, strongest, and the most powerful vampires in the world. They cannot be killed by anything on earth aside from the White Oak Stake.
.
-------2010 A.D - Alaric Saltzman - (Enhanced Original Vampire).
Enhanced Original Vampire is a term used to describe the type of Original vampire Alaric Saltzman became when the witch, Esther recast the Immortality Spell to turn him. She made changes such as binding Alaric's life to a doppelgänger, whereas the other Originals' immortality was granted by the white oak tree. This meant that he could not be killed at all, as long as the doppelgänger lived, which is why he had to guard her life.
.
-------2014 A.D - Lucien Castle and Marcel Gerard - (Upgraded Original Vampire).
They are superior to that of the Originals in very specific ways; being capable of fighting, defeating, and killing normal Originals. As an Upgraded version of an Original Vampire, it possesses a bite that is capable of killing an Original as it secretes an extremely potent strain of engineered Werewolf Venom.
