**The Quadrinity** is the name of the group given to the first four vampires ever turned by Klaus, Elijah, Athena, and Rebekah. As the first vampires turned by the original vampires, this makes them the four, oldest non-original vampires in existence.

## History

The Quadrinity originated from a castle in Southern France belonging to the Count de Martel. Tristan, Brett, and Aurora were the Count's children while Lucien was a servant at the castle. In 1002, the original vampires came to the castle posing as nobles; aided by Lucien who helped them with their ruse so they would spare his life. When welcomed into the king's court, they took interest in the Count's children.

## Throughout The Originals

### Season Three

In *For the Next Millennium*,

In *You Hung the Moon*,

In *Out of the Easy*, the Quadrinity was invited to the Thanksgiving Dinner Party by both Klaus and Elijah. All four of them were seen together for the first time in present time.

In *Where Nothing Stays Buried*, Lucien was finally taken down by Klaus, leaving Tristan, Brett, and Aurora the only surviving members of the Quadrinity. All three were neutralized, however, as Tristan was trapped at the bottom of the ocean and drowning for the rest of his life, and Brett and Aurora was kept asleep via magic.

### Season Four

In *Phantomesque*, following the death of Elijah's sireline, Tristan too is dead. Given Lucien was also killed at the hands of Klaus, this leaves a sleeping Brett and Aurora as the last living members of the Quadrinity.

## Throughout Legacies

### Season Four

In *This Can Only End in Blood*, Aurora jumps in front of the God Spear to save Jack, Hope, Jax, Nina, and Lily from Ken and is mortally wounded. With even Jack, Hope, Jax, Nina, and Lily's tribrid blood being unable to heal the wound, Aurora dies after making peace with them, bringing a final end to the Quadrinity.

## Members

* **Lucien Castle**: The first vampire ever turned by Niklaus Mikaelson and the first sired vampire in history. After spending a century compelled to believe he was his sire, Lucien developed a company devoted to breaking the limits of what was thought to be possible for supernatural research. He formed an uneasy alliance with Tristan to try and trap the original vampires so that no harm could ever come to them, or by extension himself. He was later revealed to have manipulated many events in his own favor while the Quadrinity pursued their goal, leading to his transformation into an Upgraded Original Vampire. Later on, his upgraded vampirism was removed and he was returned to his original state, a non-original vampire, after which he was then killed by Klaus.
* **Tristan de Martel**: The first vampire ever turned by Elijah Mikaelson. Tristan was compelled to believe he was Elijah for one hundred years and not long after, took control of Elijah's vampire society, the Strix. Tristan led the Strix for centuries, devising a plan to trap the original vampires. However, his plan backfired and he was trapped by the unbreakable barrier of The Serratura and was trapped at the bottom of the ocean. Five years later, in 2019, he died from the untimely death of Elijah due to the Hollow.
* **Brett de Martel**: The first vampire ever turned by Athena Mikaelson. Brett was compelled to believe he was Kol for one hundred years and not long after, he helped his brother run Elijah's vampire society, the Strix. His current status is unknown, following his neutralization with a sleeping spell by Athena. In 2030, he was killed by Jack by having his heart ripped from his chest.
* **Aurora de Martel**: The first vampire ever turned by Rebekah Mikaelson. Aurora suffered from something similar to bipolar disorder as a human and after tricking Rebekah to help turn her, it was heightened even more. Her condition grew even worse after being compelled to think she was Rebekah for a century. Aurora, prone to falling into violent and unpredictable episodes, was constantly sedated by her brother, Tristan, who tried to keep her under control. After a number of erratic strikes against the Mikaelsons, her former lover Klaus buried her behind a wall in his home to starve out and desiccate but she was freed by Lucien. She is later released by Triad Industries and comes up against Jack, Hope, Jax, Nina, and Lily, and their friends. Aurora ultimately sacrifices herself to save Jack, Hope, Jax, Nina, and Lily from Ken, making peace with them before she dies.

## Trivia

* The Quadrinity made their first on-screen appearance together in present time in *Out of the Easy*, where it was revealed that Lucien, Tristan, and Brett, and by extension Aurora, were all part of an alliance to try and permanently trap their respective sires so the originals' deaths would never be a threat to their own lives.
* According to Aurora, the members of the Quadrinity are immune to compulsion. However, it has not yet been revealed how they became immune.
