Lucie Herondale is the second and youngest child of Will Herondale and Tessa Gray, and the younger sister of James Herondale.


Lucie developed a love for writing when she was young. On her eighth birthday, James got her a thick blank book, which would become one of her most prized possessions. She kept it next to her bed and would copy her favorite pieces of her own work into it.[2]

In 1899, Lucie went to France with her mother. There, she met and, in a span of two weeks, became very close to Cordelia Carstairs. They began to exchange letters every week.[3] Some time after, at the age of twelve,[4] Lucie began to write what would become a two-thousand page novel called The Beautiful Cordelia.[2]


Her mother, Tessa, once told Magnus Bane that compared to James, Lucie was the impetuous one. She also is a very practical girl,[5] but can still be quite dreamy.[6]

Physical description

Lucie has brown hair, inherited from her mother, and pale blue eyes that are a shade lighter than her father's.

Skills and abilities

  • Nephilim physiology: Being Nephilim, Lucie is expected to possess a variety of enhanced physical and mental abilities granted to her by the angel blood of Raziel in her veins and also by the angelic Marks of the Gray Book. This includes enhanced strength, agility, stamina, and coordination, which would improve over time and practice.
  • Runic magic: Due to the angel blood in their veins, all Shadowhunters are all able to apply runes of the Gray Book on their skin without any real danger. These Marks, in turn, give varied effects that serve to benefit the wearer.
  • Demonic magic: Lucie is said to have special "talents" due to inheriting some demon blood from her mother. However, as of 1903, she is still unaware of them.





  • According to a found family tree, she went on to marry Jesse Blackthorn, with whom she continued the Blackthorn line, and died in 1959 at the age of 71 or 72. The same family tree mistakenly stated that Lucie was born in 1891.

  • While both Lucie and James gained significant, special abilities through the demon blood they inherited from their mother,[15] she, unlike James, is still unaware of them as of 1903 and it is something she wonders about.[16] Also unlike James (who has golden eyes), however, she doesn't have any physical sign of peculiarity.[17]
  • Lucie is a writer, particularly of novels,[18] and the mystery of Jesse Blackthorn's fate occupies her mind. Will would like Lucie to eventually marry Alastair Carstairs.[19] In addition to this, Lucie is much inclined to make things up.[20]
  • She and Cordelia are set to become parabatai in The Last Hours.[9]
  • Lucie can see ghosts/the dead.[21] Though this is typical of most Shadowhunters, it is possible that she, like her father, Will, just sees even those who don't want to be seen, or that it has a connection to her "gift".[22]
