|“||I am Theresa Gray, daughter of a Greater Demon and Elizabeth Gray, who was born Adele Starkweather, one of your kind. I was the wife of William Herondale, who was the head of the London Institute, and I was the mother of James Herondale and Lucie Blackthorn. Will and I raised our Shadowhunter children to protect mundanes, to live by the Laws of Clave and Covenant, and to keep to the Accords. Once, I lived among the Shadowhunters. Once I might almost have seemed like a person to you.||”|
Theresa "Tessa" Gray is an American warlock, particularly a new kind of warlock—the rare half-Shadowhunter, half-Eidolon demon. After becoming entangled herself in the lives of the Shadowhunters at the London Institute during the Victorian era, Tessa married the Shadowhunter Will Herondale.
Theresa Gray was born to the unmarked Shadowhunter Elizabeth Gray and an Eidolon demon, but raised by who everyone believed to be her father, the mundane Richard Gray. Under normal circumstances, children of Shadowhunters and demons would be stillborn, but Elizabeth was able to give birth to Tessa not only because she carried no runes, but also because she wore the clockwork angel.
For much of her early life, she was unaware of what she truly was and her true parentage. Conceived in London, Tessa's family moved to New York while Elizabeth was pregnant with her. After the death of her parents in a carriage accident when she was only three years old, she and her brother, Nate, were raised by her maternal aunt, Harriet Moore. She spent the majority of her life being overprotected by her Aunt Harriet and looking after her spoiled older brother, Nate. Tessa grew up taking comfort in books, dreaming of having the kind of adventures she read about. At sixteen, her Aunt Harriet died of what she thought was a fever. Upon her death, Nate arranged for Tessa to move to London with him.
Arrival at London
Tessa traveled from New York to London when Nate called for her, shortly after the death of their Aunt Harriet. Once there, a pair of mysterious and sinister women, whom she called the Dark Sisters, gave her a letter written in Nate's handwriting and told her that they've come to collect her on Nate's behalf.
The Dark Sisters soon revealed that they apparently had Nate as a prisoner, showing her their father's ring, one that Nate always wore, splattered with blood. They forced her to Change, or shape-shift, torturing her to learn quickly as well as threatening to harm Nate if she did not do as they asked. The Dark Sisters had made a deal with "the Magister" who had hoped to marry her and exploit her ability. In her isolation, she wrote letters to Nate about her loneliness and imprisonment, which Will later found and read.
One day, after Changing into Emma Bayliss, she was told about her marriage arrangement with the Magister, who had long been waiting for her. After a futile attempt of escape, she was finally rescued by the Shadowhunter Will Herondale. Tessa passed out in the midst of the fight against the Dark Sisters and was taken to the London Institute.
During her stay at the Institute, the head Charlotte Branwell promised to take care of her and help her search for Nate. There, Tessa befriended Jem Carstairs and the rest of the Institute's residents and staff, particularly Sophie Collins, the handmaid, while she had an uneasy relationship with Jessamine Lovelace, who wanted to move out of the Institute with Tessa.
When the investigation into her brother led them to Alexei de Quincey's house, she took the form of the vampire Camille Belcourt to infiltrate an exclusive party, with Will posing as her human subjugate and Magnus Bane, Camille's lover, as her guide. Once the human captive at the party was bitten, Will sent a signal to the Nephilim lying in wait to attack. Tessa then realized that the captive human was her brother, Nate.
During the battle, de Quincey went after Tessa, who was still in the form of Camille. Will, to save Tessa, fought him and ended up biting the vampire. After the battle, Nate was brought back to the Institute, where he was questioned and allowed to recover. Tessa got only a few moments with Nate since Jessamine, who wanted to marry a mundane so she can leave the Shadowhunter world, seemed insistent on caring for him instead, hoping Nate will fall in love with her.
Later, Tessa learned from Sophie that Will was being difficult about his treatment, which she only later found out involved drinking buckets of holy water to bring up the vampire blood he had ingested, else he would become a darkling. Tessa volunteered to take it to him in the attic, and Will finally obliged. During their rather intimate conversation, they shared their first kiss her, before Will pushed her away and insisted that she leave him. After this evening, Will became even more standoffish and unfriendly towards her, much to Tessa's confusion.
To her surprise the following day, the Shadowhunters were discussing the further interrogation of Nate, possibly by the Silent Brothers. Annoyed, Tessa made it clear that their goals are not her responsibility, and that she did her part as they searched for Nate. Before leaving, she called them out for their pretentious attitude towards Downworlders and mundanes. After having some time to feel sorry about shouting at them, particularly since she was primarily only mad at Will, she left the Institute. She was promptly followed by Jem, who then began pointing out some places in London that might help her learn to love the city, and took her to his favorite place in London—the Blackfriars Bridge. Here, Jem told her bits of his and Will's story and told her that he thinks she is no less human than him.
Unbeknownst to them, they were followed by a pair of automatons, one of them the being the clockwork coachman of the Dark Sisters, under the Magister's orders. Jem briefly engaged them before running off with Tessa and got as far as the Institute before Jem collapsed, his illness striking at a bad time; fortunately, Charlotte immediately came to their rescue. During Jem's recovery, he told her about his illness, his body's dependence on yin fen, so she wouldn't blame herself.
When her brother woke up, Nate, after quickly devising a plan that he secretly told the Magister of, bore the semblance a frightened boy who wanted nothing more than to go home with Tessa and live a normal life. Selling her and the others lies and some half-truths about the true nature of his business in London, Nate falsely told them that de Quincey really is the Magister, and that the Dark Sisters will perform the binding ritual, a spell that would improve the automatons that Magnus Bane had previously told them about, on a full moon—that same evening.
Because of the assumption that de Quincey's plan of taking over London would commence that evening, the Enclave decided to act.
When confronted by the Magister, Axel Mortmain, Tessa recalls Will's words to her earlier, explaining that the British warrior-queen Boadicea was braver than any man because she killed herself rather than be taken by the Romans. With this inspiration, she prepares to kill herself to escape Mortmain. However, she realizes that if she Changes into the form of a dead woman, particularly Adams, whose form she had already taken while under the tutelage of the Dark Sisters, she will bleed convincingly. By Changing very quickly, and for a very short time, into a woman who had been shot, she convinces Mortmain that she is dead and he leaves when confronted by Will.
Will is momentarily affectionate, but then puts an even greater distance between them. At the end of Clockwork Angel, she confronts Will, hoping to reconcile, but he is unkind, treating her like a prostitute and reveals that she is unable to have children as she is a warlock. Tessa leaves, hurt and confused.
Tessa is present, and is a key witness, at the trial of Charlotte Branwell in front of the Clave, about the attack on the London Institute. Charlotte is given two weeks to find Mortmain or she will have to resign as head of the Institute, and be replaced by Benedict Lightwood.
Tessa, accompanies Will and Jem, up to the York Institute to meet Aloysius Starkweather, who may hold a clue to the Magister's past. Jem gives her the Carstairs family ring, so that she can pretend to be a mundane girl, who is engaged to Jem.
Sophie Collins comes to Tessa with an invitation to a masked ball at the Lightwood's house, addressed to Jessamine from Nate. Jessamine slapped Sophie when she saw Sophie with it, so Sophie hit her on the head with a silver hand-mirror and knocked her out. Tessa sends Sophie to Will for help, and he places a sleeping rune on Jessamine so that she will not wake up until morning, and ties her to her bed as a precaution. Tessa Changes into Jessamaine, and Will accompanies her, so that she can sneak into Benedict Lightwood's house. Tessa meets Nate, who dances with Jessamine, and reminds her that she is now 'Jessamine Gray'.
Jem proposes to Tessa, and gives her his mother's jade pendant as a token of their engagement. However, Will arrives back from Magnus' house after the demon, Marbas, reveals that there was no curse on him. He talks to Tessa in private and declares his love for her, but she rejects him and tells him that she is engaged to Jem.
In Clockwork Princess, she is revealed to be a half-Shadowhunter, half-Demon, a new species, because her mother Elizabeth Gray, the real Adele Starkweather, was a Shadowhunter who bore no runes, and her father was replaced by an Eidolon Demon, making her a hybrid and an immortal.
She is kidnapped in an assault on the Institute at the delivery of Jessamine from the Silent City where she is taken to The Magister, who has taken up refuge in Cadair Idris near Will and Cecily's former home. Will then came and found them, but his long trip was to no avail as he is quickly captured by his own stupidity and Mortmain's invisible wall. The rest of the Enclave then shows up, accompanied by three Silent Brothers: Enoch, Micah, and Zachariah.
In the fight with the Infernal Devices, it is revealed that her fiancé, Jem, had become a Silent Brother, Brother Zachariah. Since Silent Brothers cannot marry, they are separated.
Tessa eventually married Will, and the two stayed together for at least 60 years. Wanting to at least physically age with her husband, Tessa made herself look older. During their thirtieth wedding anniversary, Will took the bracelet Tessa wore on their wedding, which bore the wedding runes she could not, and had it redesigned with pearls. Tessa stayed with Will until his death in 1937. After Will's death, Tessa kept her distance from her family, not wanting to go through the pain of seeing her children and other loved ones grow old while she remained youthful.
Two years after the Uprising, Tessa was staying with Magnus in New York when Jocelyn Fairchild came to ask him to protect her daughter, Clary. Tessa, in the place of an Iron Sister, then performed the Shadowhunter children's ritual on Clary with Brother Zachariah. Pleased to meet her, Jocelyn took up the surname "Fray", a portmanteau of Fairchild and Gray, in honor of Tessa's friendship with her ancestors.
Saddened by the Uprising, and the thought that the Herondales, the line of her and her husband, were gone, Tessa retreated to the Spiral Labyrinth and spent most of her time there, away from the rest of the world and its troubles. She instead focused on her research as a more scholarly warlock, aiding the Nephilim on occasion.
In September 2007, after the Mortal War, Tessa was at Alicante and had found out that Stephen Herondale's son, Jace, was in fact alive. She hoped to speak with him, though Magnus told her to give him some time to accept his own lineage before she burdens him with the past. While speaking with Magnus, Clary noticed her and even vaguely remembered her, thinking she was familiar, but did not remember from when. At that time, Tessa was wearing white, mourning certain deaths, such as Ragnor's. Tessa returned to the Labyrinth afterwards.
In January 2008, during their annual meet-up at the Blackfriars Bridge, Jem surprised her by arriving as a mortal, no longer a Silent Brother nor dependent on his yin fen as he has been cured by Jace Herondale and his heavenly fire. Though surprised, Tessa welcomed him back into her life wholeheartedly, and the pair rekindled their relationship, sharing a kiss at the bridge. They agreed to see the world together, and Jem told her the "story of Lightwoods and Herondales and Fairchilds".
In May, they attended the wedding of Jocelyn and Luke. There, Jocelyn formally introduced her to Clary, who slightly recognized her. During the conversation, Tessa told Clary that she felt a kinship towards their families, and gave her her copy of the Shadowhunter's Codex, as well as the Herondale family ring that was once her son's, James, to pass onto Jace. While Jace has finally accepted the Herondale name, she, and Magnus, still opted to give him a bit more time to adjust and be happy on his own.
Tessa has smooth brown hair, steely gray-blue eyes, and is considerably taller than other girls and boys her age. While she used to think herself average, several of her friends have noted that Tessa is pretty and beautiful; not conventionally beautiful, but kindly attractive. Being immortal, Tessa stopped aging young and appears like a young woman in her early twenties.
- Immortality - Tessa is immortal, having maintained her youthful appearance since the 19th century.
- Magic - In The Midnight Heir, Tessa is described to have "a small sphere of light shining in her palm," and Magnus says, "'Been taking magic lessons, have we, Tessa?'"
- Changing - As a child of an Eidolon demon, she has inherited the ability to Change; the demonic power to shape-shift into another person. Unlike ordinary Eidolon demons like Mrs. Dark, Tessa can become whomever she transforms into as long as she has a physical object of theirs when she first turns into them. She achieves the Change by linking with a psychic impression or remnant of a person contained within an object. She can also Change by linking with a person's soul, as she did when she Changed into the Angel Ithuriel. In addition to their physical presence, Tessa is also able to touch the mind of a person and access their memories and thoughts when Changing, taking on their memories, mannerisms, and abilities.

- As of the 21st century, Tessa apparently has about fifty or sixty living descendants.
- Tessa chooses to go by her "warlock name", a one syllable surname, Gray, as she does not want to be identified as a Shadowhunter, despite technically being a Starkweather by birth and a Herondale and Carstairs by marriage.
- Jocelyn Fray formed their mundane surname "Fray", a portmanteau of Fairchild and Gray, as an homage to Tessa and her close relationship with the Fairchilds.
- Tessa, like Clary, is a main protagonist and narrator in Cassandra Clare's book series. In the first book, both are attacked and knocked unconscious by demons and are brought to the Institute by one of their potential love interests, particularly Will for Tessa and Jace for Clary. Both also walk in on their love interests playing a musical instrument in a room at the Institute; Jem was playing violin, and Jace was playing the piano, and both mistook the girls to be their parabatai before seeing them.
