Livia Blackthorn is one of the young Blackthorns residing in the Los Angeles Institute with Julian Blackthorn, her twin brother Ty, and their other siblings.



Livvy was born into the Blackthorn family to Andrew and Eleanor Blackthorn in 1997. She is the fourth of seven children, including her half-siblings Helen and Mark, and was born within minutes before her twin brother Ty.[1][2][3][4] Livia remains among the few people by whom Ty doesn't mind being touched, as well as one of the few people who can effectively calm him down.

A young Livvy was with Helen, Ty, Jules, and presumably the rest of their siblings while their family visited the New York Institute in 2007. According to Jules, she and Ty were eating wax, much to Helen's frustration.[5]

Dark War

In December of 2007, the Los Angeles Institute was attacked by Sebastian Morgenstern and his Endarkened army. Along with her siblings (with the exception of Mark and Helen, the latter of whom was in Alicante at the time of the attack), Livia managed to escape through a Portal, which was opened by the Clave upon Jules' emergency request.

Once there, Livia was among the children who were interrogated with the Mortal Sword, after learning that their father was among the Clave members who were Turned into Dark Shadowhunters by the Infernal Cup. Eventually, they also learned that their brother Mark had been forced to join the Wild Hunt.

The next time they saw their father was during the battle in Alicante, during which the children were sent to hide in the Accords Hall. There, Andrew quickly found his children and immediately began to approach them menacingly. Jules saw that his father was truly gone after being Turned, and ultimately killed him before he could hurt Ty or his other siblings. When Ty threw a fit afterward, Livia tried to calm him down, knowing that Jules had no choice but to do what he did.[6]

Eventually, the children returned to Los Angeles where their uncle, Arthur, joined them shortly after took over as head of the Los Angeles Institute. He remained a distant figure, however, while their new tutor, Diana Wrayburn, and Julian were more involved with their development.[7]

Livia, like her other siblings, has the Blackthorn brown hair and blue-green eyes.

Skills and abilities

  • Nephilim physiology: Being Nephilim, Livia possesses a variety of enhanced physical and mental abilities granted to her by the angel blood of Raziel in his veins and also by the angelic Marks of the Gray Book. This includes enhanced strength, speed, agility, stamina, and coordination, which continue to improve over time and practice.
    • The Sight: As a Shadowhunter, Livia is naturally and easily able to see through most magical illusions and layers of glamour over reality.
    • Runic magic: Due to the angel blood in their veins, all Shadowhunters are able to apply runes on their skin without any real danger. These Marks, in turn, give varied effects that serve to benefit the wearer.
    • Use of heavenly weapons: As a Shadowhunter, Livia is also able to perform tasks unique to their species, such as the ability to use and call on the power of angels for their seraph blades, as well as to handle any heavenly weapons or objects with effect, which would normally not work for other species. In particular, these are tools made of adamas and forged by Iron Sisters.
  • Swordsmanship: Livia is a skilled fencer and sword fighter, especially with her saber equipped.





Following the family tradition of Greek and Latin names, Andrew named her Livia after a Roman empress who was married to Tiberius Claudius Nero, after whom Andrew named her twin brother, a deliberate instance that Andrew found funny. Finding her own name odd, she often tells people that her name is Olivia.[9]


  • Livvy is also mathematically-minded. She is fascinated by fractal patterns. She would often help her siblings when they struggle with their math. She and Ty picked up the hobby of studying computers—whereas Ty liked analyzing and organizing the patterns, she was more involved with the mathematical aspect the programming and coding.[7] Sometimes even her tutor Diana wishes she could go to college and take a higher level math course.[8]
  • She wants to become parabatai with Ty, but he refuses, mostly because of his desire to go to the Scholomance.[7]
  • Livvy and Ty's rooms are across the hall from each other. Her room is clean and well-decorated. Her bed's headboard is covered with fabric decorated with a teacup pattern, bright costume jewelry hangs from screens nailed to the wall, and books about computers and programming languages are stacked in orderly rows by her bed.[7]

  • She and Ty were originally supposed to only be nine months younger than Jules.[10] They were also supposed to have have a made-up twin language only they can understand.[11]
