Infernal Devices/Characters

A listing of characters that appear in The Infernal Devices trilogy by Cassandra Clare.

This series is a prequel to her other series, The Mortal Instruments. Check out that character sheet, too.

Theresa "Tessa" Gray
Tessa has spent the first sixteen years of her life being overprotected by her aunt after the death of her parents in a carriage accident. She lives almost all her life in books, dreaming of having the kind of adventures the heroines she reads about do—until she is forced to travel from New York to London when her brother Nathaniel goes missing and only a pair of mysterious—and sinister—women called the Dark Sisters seem to know where he might have gone. The Shadowhunters of the London Institute may be Tessa's only hope of finding Nate, but their mysterious world of demons and Downworlders holds many dangers for her—especially when she realizes she might be more a part of it than she'd thought.


 * Affectionate Nickname: She is called Tessa by most everyone, Tessie by her brother, and Tess by Will.
 * All Girls Want Bad Boys / Single Woman Seeks Good Man: Will and Jem respectively.
 * Arranged Marriage: Tessa was going to be forced to marry the Magister had she not been rescued by Will. She was obviously not very happy about it.

 * Expy: Critics argue that Tessa is a less snarky version of Clary from the sequel series, The Mortal Instruments.
 * Faking the Dead: See Driven to Suicide.
 * First Kiss:
 * Genre Savvy: Because she's so wide-read.
 * Good Angel, Bad Angel: Played with by having Jem and Will be Tessa's angels, respectively. It doesn't hurt that they're both part angel.
 * Gray Eyes
 * Half-Human Hybrid: She's a warlock.
 * The Hero: Of the Five-Man Band
 * Love Triangle: Will-->Tessa<--Jem
 * Meaningful Name: Word of God says to look up on why Tessa's surname name is so similar to Clary's fake last one (Fray), and there's also the matter of the Gray Book.
 * Morality Pet: For Will.
 * Parental Abandonment: Her parents died when she was three.
 * Plucky Girl
 * Shape Shifter: This starts off the whole story because of her ability to change into anyone, even possessing some of their memories and personality (she just has to touch one of their items to do it the first time).
 * Dead Person Impersonation: She can do this.
 * Humanshifting: This is the whole basis of her powers.
 * Not Quite Back to Normal: She worries that this would happen eventually.

 * Wide-Eyed Idealist: Tessa always compares her adventures to what she's read and hopes for the best of all situations.

William "Will" Herondale
Seventeen-year-old Will is the sort of young man nice Victorian girls were warned against. He drinks, gambles, and enjoys the company of ladies of questionable virtue—at least, as much as he enjoys anything. Will hates everyone and everything, with the possible exception of Jem, and even that's in some doubt. Charlotte despairs of keeping him alive past the age of nineteen. When he finds himself oddly drawn to Tessa, his friends begin to hope that the Downworlder girl will prove Will's unlikely salvation—but as Tessa grows closer to the bleak secret that makes his life a prison, danger threatens to destroy them both if she ever finds out the truth.

"Gabriel: You know, there was a time when I thought we could be friends.
 * All Girls Want Bad Boys: Will constantly says he's always out drinking and gambling, and that there are a dozen girls who've claimed that he'd compromised their virtue.
 * Blue Eyes
 * British Accents
 * Byronic Hero
 * Cartwright Curse:
 * Cassandra Truth:
 * The Charmer
 * Chronic Hero Syndrome: According to Jessamine, Will thinks he's Galahad. And it's true.
 * Dark and Troubled Past: Or at least, he alludes to one quite often.
 * Deadpan Snarker: Oh, Will.
 * Deadpan Snarker: Oh, Will.

Will: There was a time when I thought I was a ferret, but that turned out to be the opium haze. Did you know it had that effect? 'Cause I didn't."

"“They’re not hideous,” said Tessa.
 * And there's this scene from Clockwork Prince:

Will blinked at her. “What?”

“Gideon and Gabriel,” said Tessa. “They’re really quite good-looking, not hideous at all.”

“I spoke,” said Will, in sepulchral tones, “of the pitch-black inner depths of their souls.”

Tessa snorted. “And what color do you suppose the inner depths of your soul are, Will Herondale?”

“Mauve,” said Will."


 * Emo Teen: According to fans.
 * Estrogen Brigade Bait: Big time. Will's good looks are given a lot of attention.
 * Even the Guys Want Him: Magnus and de Quincey both hint this about will. Can't blame 'em, though.
 * Expy: One can sum up Will by saying he's a ruder, snarkier, British, different-colored version of Jace from the previous series. Maybe it's the Herondale blood.
 * First Kiss:
 * Foil: To Jem.
 * The Gambling Addict
 * Heterosexual Life Partners: With Jem. He and Will are parabatai, basically meaning they stick to one another and cover each other in a fight.
 * Hollywood Atheist: Pulvis et umbra sumus. For those who don't read Horace, that means "we are dust and shadows," pretty much said by Will to be what he believes in.
 * I See Dead People: Confirmed in the first chapter of Clockwork Prince to be one of the few Shadowhunters that can.
 * Insecure Love Interest
 * Jade-Colored Glasses: He alludes to a traumatic childhood quite often.
 * Jerkass: He occasionally strays into Jerk with a Heart of Gold territory, but as of now, he isn't.
 * Jerkass Facade:
 * The Lancer of the Five-Man Band
 * Mood Swinger
 * Morality Pet: Jem, who seems to be the only person whose well-being Will actually seems to give a damn about. Tessa looks like she's becoming one.
 * Odd Friendship / Opposites Attract: With Jem - Will is a rude asshole and Jem is a kindhearted nice guy. They even look absolutely different: Jem is all white and silver and Will is all dark colors.
 * Running Gag: There is no such thing as demon pox.
 * Sensitive Guy and Manly Man: With Jem. No points for guessing which one he is.
 * Stock Foreign Name
 * Tall, Dark and Handsome and Tall, Dark and Snarky: Mmmhm.
 * Troubled but Cute
 * Tall, Dark and Handsome and Tall, Dark and Snarky: Mmmhm.
 * Troubled but Cute

James "Jem" Carstairs
Brought up in the Institute in Shanghai, Jem's parents were —but with a terrible price to be paid. Frail and silver-haired, Jem seems an unlikely demon-killer, but his skills and swift intelligence make him a formidable foe. He finds a kindred spirit in Tessa as both of them feel they are torn between two worlds, neither belonging completely to one or to the other. As Jem's affection for her grows, will Will have to hurt the only person in his life he's ever seemed to care about?


 * But Not Too Foreign: Half-Brit, half Chinese, which was unusual for the time period given the state of relations between Britain and China.
 * Chronic Hero Syndrome: According to Jessamine. Not as much as Will, though.
 * Conveniently an Orphan
 * Dark and Troubled Past:
 * Deadpan Snarker: His snarkiness comes mostly from saying something, then adding "Not really" with something humorous. He can play the trope completely straight, though.

 * Elegant Classical Musician: He can play the violin, and quite well, too.

 * Morality Pet: For Will.
 * Nice Guy
 * The Not Love Interest: For Will.
 * Oblivious to Love: Probably can't tell that Sophie's sweet on him.
 * Odd Friendship / Opposites Attract: With Will.
 * The Smart Guy of the Five-Man Band
 * Sensitive Guy and Manly Man: The Sensitive Guy to Will's Manly Man, Will's tendencies often making him look near-saintlike in comparison.
 * Soap Opera Disease:
 * Stock Foreign Name
 * Sword Cane: His Weapon of Choice is a jade-tipped one.
 * Technicolor Eyes / Gray Eyes: Jem's eyes, like his hair, are silver.
 * White-Haired Pretty Boy: His hair is described as silver, and he has little of the aloofness (or the evil-ness), but he still fits the trope.
 * Your Days Are Numbered

Charlotte Branwell (nee Fairchild)
Twenty-three-year-old Charlotte runs the entire Institute with a capable hand. Kind and loving, she does her best to care for the orphaned Shadowhunters who live under her roof while hiding her loneliness from the absent-minded husband she loves. It seems as if there's nothing Charlotte can't manage—until Tessa's search for her missing brother begins to uncover a web of corruption and deceit in London's Downworld that threatens to tear London's Conclave of Shadowhunters apart.


 * Brainy Brunette: Charlotte is very intelligent.
 * The Chick of the Five-Man Band
 * Deadly Disc: Uses two on the battle after Blackfriar Bridge.
 * Happily Married: With Henry, more or less, despite his awkward Genius Ditz-ness.
 * Huge Guy, Tiny Girl: Tiny girl to Henry's huge guy.
 * Like a Son to Me: It's almost as if Will, Jem, and Jessamine were her own children, except, according to her, for the part where they were required to love her.
 * In the Blood: It's mentioned in passing that her father was the previous caretaker of the Institute.
 * Parental Substitute: Raised Will, Jem, and Jessie since they came to the institute. Will says that she would have been called a governess had she not been so intelligent and if she didn't have the ability to chop one into pieces.
 * Team Mom: Her main function is basically making sure everybody doesn't kill everybody.
 * Younger Than They Look: Charlotte's small size is countered by the air of competence she exudes, and Tessa says she had assumed her to be much older than twenty-three.
 * Younger Than They Look: Charlotte's small size is countered by the air of competence she exudes, and Tessa says she had assumed her to be much older than twenty-three.

Henry Branwell
Absent-minded and brilliant, Henry spends his waking hours in the crypt of the Institute, inventing fabulous machines and weapons out of cogs cams and gears. Unfortunately just as many of Henry's inventions don't work as the ones that do, and Henry is as likely to set himself on fire as he is to invent something new and amazing. When Tessa finds herself followed by a silent band of assassins who turn out to be automata—human beings made from clockwork parts—it is Henry who must decipher how they work in order to find the demonic mechanical genius at the heart of the most evil plan London's supernatural world has ever seen.


 * Absent-Minded Professor: He would be...if he actually was a professor.
 * The Big Guy of the Five-Man Band
 * Bungling Inventor
 * Bunny Ears Lawyer
 * Gadgeteer Genius: His defining character trait.

 * Happily Married: To Charlotte, more or less.
 * Huge Guy, Tiny Girl: Huge guy to Charlotte's tiny girl.
 * Phlebotinum Breakdown: What most of his inventions end up doing.

Jessamine Lovelace
Jessamine's parents, like Will's were Shadowhunters who left the Clave. Their deaths in a fire orphaned her, leaving her to be brought up in the Institute by Charlotte and Henry. Jessamine hates everything about being a Shadowhunter, from the training to the danger to the existence of demons, which she sees as "smelly and disgusting." Armed with a razor-edged parasol and an equally sharp tongue, Jessamine can be dangerous if she wants to be—to herself as much as to the supernatural creatures she's sometimes forced to encounter.


 * British Accents
 * Brown Eyes
 * Crouching Moron, Hidden Badass: Well, Shadowhunter blood is dominant.
 * Deadpan Snarker

 * The Fashionista: Jessamine is very concerned about how she looks, and it's she who takes Tessa out to buy new dresses.
 * Hair of Gold
 * I Just Want to Be Loved: Implied to be her motivations for her actions in the second book.
 * Improbable Weapon User: She uses a parasol Henry made for her. The fabric is edged with electrum, though.
 * The Load: Played straight and subverted with Jessamine.
 * Love Freak / In Love with Love: She wants someone to take her away from the Institute.
 * Parasol of Prettiness: Aw, look at Jessamine's parasol! It's so pretty and pink and it even has flowers on it...
 * Parasol of Pain: ...and the edges are laced with electrum. Ouch.
 * Proper Lady: Strives to be this. She fails because of her attitude.
 * Razor Floss: Edges her parasol, turning it into an effective weapon.
 * Reluctant Warrior: Although she's no Actual Pacifist. She just really, really hates the Shadowhunter world.
 * The Sixth Ranger of the Five-Man Band: Due to her dislike of the Shadowhunter world.
 * Spoiled Brat: More or less.
 * The Sixth Ranger of the Five-Man Band: Due to her dislike of the Shadowhunter world.

Gabriel Lightwood
Benedict's younger son and Will's apparent rival.


 * Big Brother Instinct: Will says the reason Gabriel hates him so much is because he compromised the latter's sister's virtue. But then again, it's Will, so we don't know if that's true or not. As of the second book, it's apparently because Will rejected his little sister's advances (in his defense, she was a lovesick twelve-year-old) and broke Gabriel's arm in public.

 * Jerkass: Quite blatantly.
 * The Rival: Presumably to Will.
 * Sibling Yin-Yang: With Gideon.

 * Gratuitous Spanish
 * Gray-Green Eyes: Gray for his calmness, green for his Shadowhunter powers.
 * Informed Flaw: Is supposedly an even bigger Jerkass than his little brother, although he's shown himself to be nicer than Gabriel. Considering that was Will speaking, it's no wonder.
 * Character Development: He was possibly a bigger asshole than Gabriel, but he shaped up during his time in Spain.
 * Sibling Yin-Yang: With Gabriel.
 * Star-Crossed Lovers:
 * The Stoic

 * Our Vampires Are Different
 * Proper Lady: Behaves like this.

 * The Scapegoat: In all honesty, de Quincey is not the poster boy for morality,

Magnus Bane

 * Bi the Way: Although you'd only know it by reading the sequel series. He's certainly still quite campy even in this series.
 * Call Back: Magnus tells Tessa he has a thing for people with blue eyes and black hair. Who has blue eyes and black hair? Alec from Mortal Instruments! Though, since this is the prequel trilogy, it's really more of a call forward...
 * Even the Guys Want Him: It's said that de Quincey is interested in him as "more than friends".
 * Interspecies Romance: With Camille.
 * Love Martyr: Has shades of this for Camille.
 * Token Minority: Like Jem, he's part Asian.
