The Originals, a spin-off of The Vampire Diaries, centers on three of the Mikaelson siblings: Klaus, Elijah, and Rebekah. The Mikaelson family are also commonly known as "the Originals" due to the fact that they are the first vampires ever to exist. Klaus is the son of a witch and a werewolf, and his quest to unleash his hybrid nature was detailed in The Vampire Diaries. The backdoor pilot, "The Originals", which aired on April 25, 2013, also revealed that the werewolf Hayley, with whom Klaus had a drunken one-night stand in season 4 of The Vampire Diaries, is pregnant with his child the first ever tribrid. Elijah, Klaus, Rebekah and Hayley are all introduced in The Vampire Diaries as part of main or recurring cast from season 3 or 4 unlike the other cast of The Originals who are not introduced until the backdoor pilot or later on in the series.
The series begins with the Mikaelson siblings returning to the city of New Orleans for the first time since 1919, where a pregnant Hayley has also settled and is under capture by the witches who use her to manipulate Klaus into helping them against Marcel's iron fist. Having originally built the French Quarter, they had been forced to abandon it when fleeing from their vengeful father, Mikael, who wished to kill them all and end the vampire species which he viewed as unnatural and evil. In their absence, Klaus's former protégé and adoptive son and Rebekah's former lover, Marcel, took charge of the French Quarter as self-proclaimed king. Klaus resolves that they must take down Marcel and get back the city that once belonged to them while protecting their city from a war brewing between vampires, werewolves, and witches.
The first season describes how Klaus's mystical child is going to be born and speaks of the threats that the Originals together must keep her safe from. It also details the war between vampires, witches and werewolves. The series ends with the child being born – a baby girl named Hope and being given to Rebekah to hide and protect after Klaus and Hayley fake her death to ensure her safety. Hayley is turned into a hybrid through Hope's blood after being murdered when giving birth.
The second season deals with the return of Mikael and Esther, the Mikaelson siblings' parents, the arrival of Dahlia, sister of Esther who threatens Hope's life as she wishes to take her and train her in her image as she did with Freya the supposedly dead first-born daughter of Mikael and Esther who was said to die due to the cold winter, who shows up to help the Mikaelsons against Dahlia, having been kidnapped by her a few years after her birth after Esther promised Freya to her after birth but did not deliver.
'The third season begins with the return of Lucien Castle, the first vampire sired by Klaus. Lucien tells Klaus about a prophecy that speaks of the Mikaelsons' downfall through friend, foe and family. In an effort to battle the Mikaelsons, Lucien works with Tristan de Martel and his sister Aurora – Klaus' first love, the first vampires sired by Elijah and Rebekah respectively. This season sees the death of Hayley's husband werewolf Jackson by Tristan and the death of Camille by Lucien. This season is also the first one to have a crossover episode with The Vampire Diaries, with Stefan Salvatore coming to New Orleans seeking aid.
The fourth season takes place five years after the third season. Marcel, now an Upgraded Original Vampire due to Lucien's creation, is ruling the city with an iron fist once more, while Hayley cures Freya, Elijah, Rebekah, and Kol. Klaus suffers at Marcel's hand as the other Mikaelson siblings strive to save him. But the appearance of an evil ancient mystical menace called the Hollow puts them all at risk, especially Hope who is targeted for her magical abilities and tribrid nature. It is revealed later in the season that the Hollow created the first werewolves which Hayley descends from. Hope is seven years old here and starting to develop magical abilities which Freya helps her control and use.
The fifth and final season of the series takes place seven years after the fourth season. Hope, now a teenager, is studying at the Salvatore School for the Young and Gifted. The other Mikaelsons are living their own lives separately, trying to keep the Hollow at bay through their distance. But when Klaus and an amnesiac Elijah meet, Hayley goes missing and Nazi vampires emerge the family all return to New Orleans to fight these new brewing threats. This season also acts as a soft backdoor pilot through small incorprations of the Salvatore School and future Legacies characters Alaric, Landon Kirby, and the Saltzman twins as younger versions.
