Annabel Blackthorn

Annabel Callisto Blackthorn is a major antagonist of The Dark Artifices series by Cassandra Clare.

Early Life
Annabel in her early years lived in Cornwall, England where she spent most of her first life. Around this time, her family adopted a warlock named Malcolm Fade into their household where every family member except Annabel treated him brutally. Over time, they fell in love and when her family found out, they killed her out of shame and disgrace for their family name. She was buried by a tomb in the sea.

Resurrection
Feeling vengeful for his love's death, Malcolm attempted to resurrect her over the years to no avail. He then sought out the help of the Unseelie King. The Unseelie King told him how to raise her with the assistance of the Black Volume of the Dead. The spell was only partially successful though and she spent 5 years half conscious and in incomparable pain.

When Malcolm found out how to finish the spell though, she stabbed him repeatedly numerous times because he disrupted her death in which she said was a gift. She then took the Black Volume and departed.

Annabel was eventually tracked down by Julian Blackthorn and he offered her safety and security in exchange for the Black Volume. She then went to Idris with him but after feeling a moment of panic, stabs Robert Lightwood and Livia Blackthorn, killing them.

Faerie and Thule
Annabel found her way back to the Unseelie Lands and in them, found Ash who she became obsessed with as he had had a perfect loyalty spell placed on him. She kept the Black Volume with her as the King wanted to bargain for it. Keeping it allowed her to stay around Ash.

When the Seelie Queen gave him a copy though, she realised that Ash would be in danger so she took him with her into the portal to Thule when she opened one up. There, she found Sebastian Morgernstern who allowed her to torture and kill people. This earnt her the nickname of 'Queen of Air and Darkness'.

Annabel then realised that Sebastian was getting weaker and she also knew that Ash would be in danger as Sebastian could kill him for his strength. In an attempt to save Ash from his fate, she bargained with Julian Blackthorn and Emma Carstairs in which she would open a portal for them so that they could go back home, but they had to bring Ash with them.

During the last battle there, she was killed by Julian as she refused to allow them to cross into the portal without Ash.

Personality
Annabel is shown to be a very deceptive and machiavellian person as she has been consumed by her own rage from her life and resurrection. She can be kind to her family members though as shown in Lord of Shadows when she arrived to help Julian with his mission. She is also very protective to those she loves as she stayed with Malcolm through all of the prejudice and Ash even sacrificing herself for him.
