Sirelines

**Notice:** This **article** uses content directly taken from the Sirelines **article** at the Vampire Diaries Wiki, and is licensed under the Creative Commons Attribution-Share Alike License.

A **Sireline** is a figurative bloodline of vampires or hybrids and the chain of those by whom they have been sired. If the originator of a bloodline is permanently killed with a White Oak Stake, or by other means, everyone in their bloodline dies within a few hours. It was a powerful and sophisticated link added to the immortality spell by Esther as a method of further protecting her children.

## Trivia

* Mikael was the first Original vampire destroyed. However, it is never mentioned if he sired any vampires, nor is there any mention of the destruction of vampires in a sudden and mysterious way. It is assumed that he never sired any, given he despised vampires, even after becoming a vampire hunter, and his preference to feed off of vampires.
* An Original's spirit has to die in order to kill off their bloodline. Even though Klaus' body was supposedly destroyed in *The Departed*, his soul was in Tyler Lockwood's body, so his bloodline remained unharmed.
	+ However it is possible, that since Klaus' body was not destroyed, that is the reason his bloodline remained intact. This seems to be the case as Esther wished to destroy Rebekah's body after she was jumped into Eva's body.
* Julie Plec confirmed that Klaus is the origin of the bloodline Stefan, Damon, Caroline and Elena are from.
* It is possible to unlink a vampire from their bloodline using magic. This was successfully performed on Klaus by Davina. For reasons unknown, Klaus never sired new vampires after his sireline was severed.
* According to Lucien, vampires from all over the world heard that an attack was made on Klaus' life by Dahlia. Lucien also stated that each of the sirelines were at war and an attack may be made on either of their lives.
* Kol is the only Original who's first sired vampire or sireline members are still unknown. Following Kol's resurrection, it is not known whether he's sired any new vampires.
