Annabel knew the warlock Malcolm Fade from childhood; by the time she became of age, they had fallen in love. Due to the strict laws prohibiting relationships between Nephilim and Downworlders prior to the Accords, Annabel and Malcolm planned to run away together. These plans were discovered by Annabel's family, who locked her in a tower where the warlock could not reach her. Rumors soon spread that Annabel was sent to the Adamant Citadel to become an Iron Sister, and many, including Malcolm, believed this to be the truth. However, it was later discovered that the Blackthorn family, horrified and ashamed of what Annabel did, buried her alive in a tomb by the sea.
It would only be years later when Malcolm found out what truly happened to her. Heartbroken by Annabel's murder, Malcolm became obsessed with raising her from the dead. He found her tomb and moved her body to the convergence, still keeping it near the ocean because he knew that she had loved the water in her life. Fade soon sought the assistance of the Unseelie King who provided the warlock with instructions to resurrect Annabel. The instructions were in the form of a poem, and has since been printed in Nephilim texts as follows:
- "First the flame and then the flood:
- In the end, it's Blackthorn blood.
- Seek thou to forget what's past
- First thirteen and then the last.
- Search not the book of angels gray,
- Red or white will lead you far astray.
- To regain what you have lost,
- Find the black book at any cost."
Decades after her death, Malcolm finally learned how to bring her back to life. He began trying to accomplish a necromantic ritual, one that required sacrifices. In August 2012, Malcolm attempted to complete the ritual by kidnapping Octavian Blackthorn but was interrupted by the Los Angeles Shadowhunters, and Malcolm was stabbed in the chest by Emma Carstairs. Fade's body was then thrust into the Pacific Ocean with the Black Volume of the Dead through an underground opening to the sea.
Because of this, sea water and Malcolm's blood began to leak into Annabel's coffin. She was awakened—the extent of which is unknown, given that Malcolm was not able to complete the necessary ritual and was thus not what woke her—and was able to open her eyes; it remains to be seen if she was truly resurrected or not.
- She is missing a finger, specifically her ring finger.
