|“||Life is a book, and there are a thousand pages I have not yet read. I would read them together with you, as many as I can, before I die—||”|
Will was the son of Edmund Herondale, a former Shadowhunter, and Linette Owens, the mundane whom Edmund left his Shadowhunting life behind for. As dictated by the Nephilim Law, Will and his sisters, Ella and Cecily, being Nephilim, were still welcome to becoming Shadowhunters. Hence, Will was asked twice in twelve years, both times he refused, after being raised to believe that Shadowhunters were not good people and that the lives they led were dangerous and monstrous.
However, shortly after the second time he was offered, when he was twelve years old, Will was going over his father's old things when he found the Pyxis that held the Greater Demon Marbas and opened it, unwittingly unleashing the demon. The demon then went on to attack him, and Will was protected by his older sister, Ella, who was subsequently poisoned by the demon. Before it left, Marbas claimed to have placed a curse on Will, telling him that those he love will die. When Ella died the next morning, Will was wracked with guilt and sorrow, believing himself to be responsible. Will then immediately decided to leave and join the Shadowhunters at the London Institute to keep his family safe.
Even in London, Will was haunted by the demon's curse. Will remained distant from the other inhabitants of the Institute, Charlotte and Henry, not wanting to bring harm to them by becoming attached and learning to love them. One time at a Christmas party at the Institute, Will found the diary of a twelve year old Shadowhunter named Tatiana Lightwood who had a crush on him. In the diary, Will found poems Tatiana wrote about him and she wrote her name as Tatiana Herondale. Believing in the curse, Will decided to put a stop to Tatiana's crush on him by reading the poems in front of the rest of the guests. Tatiana run out of the room in embarrassment, causing her older brother Gabriel to try and attack Will, only to get his arm broken. Since then, the two boys have an animosity towards each other.
When Jem Carstairs arrived from Shanghai in 1873, Will tried to be rude to the boy to immediately dissuade him from trying to befriend him. However, Jem refused to be intimidated by Will and insisted in training with him. When Will learned that Jem was ill, however, Will lightened up and allowed himself to become close to Jem ever since, seeing him as his "great sin", convincing himself that since Jem was already dying, the curse would be worthless against him. When they were thirteen, Will asked Jem to become his parabatai and when they were fourteen, they underwent the ceremony and became parabatai.
Will and his parabatai, Jem, found Emma Bayliss, who had been murdered by a man from the Pandemonium Club, she was being followed by a demon that was killed by Will. They found a dagger with the 'ouroboros' symbol on it's hilt.
Will rescued Tessa Gray from the Dark Sister's house, where she had been kept prisoner. Tessa threw a china jug at him, thinking he was one of the Dark Sisters or Miranda, their servant. However, it hit his arm and injured him. He took her back to the Institute after fighting the Dark Sisters, and beheading Mrs. Black.
Will met Camille Belcourt and accompanied Tessa, who was disguised as Camille, to de Quincey's ball for Downworlders, as her human subjugate. He tried to set off the alarm to alert the other Shadowhunters, but instead set the curtains on fire. Fortunately, the Shadowhunters realized something was wrong and attacked the mansion, killing the majority of Vampires who had broken the Accords. Will fought and bit de Quincey, after pulling him off Tessa, who had changed back into her human form, but he escaped.
Tessa brought holy water to Will, who was forcing himself to throw up any vampire blood he had swallowed so that he would not become a Darkling. Will, who later blamed it on the vampire blood, kissed her passionately.
Axel Mortmain arrived at the Institute, warning the Shadowhunters that the Dark Sisters were planning on animating the Magister's Clockwork Army. Will and Jem rushed off to stop the Dark Sisters. However they arrived at the abandoned mansion to find only Mrs. Dark conducting a necromantic spell to bring her sister back to life. Realizing that they had been tricked, they rushed back to the Institute but Will left Jem behind with the carriage.
Will found Tessa on the floor, with Mortmain next to her, who was surprisingly upset. Mortmain fled after being confronted by Will. Will rushed toward her, upset at her death. He cradled her head in his lap, but then realized she was breathing. Tessa opened her eyes and told Will that she tricked Mortmain into believing that she had stabbed herself. Will however was distraught as he believed that he had lost everything.
On an errand for Magnus Bane, Will visited a graveyard and gave 'Old Molly', a ghost, some rings in payment for ingredients for one of Magnus' spells. He asked the ghost if she could supply the opposite of a love potion, however she suggested for him to act nastily and scare the girl away. As he left, he muttered to himself that it was for him, not her.
Tessa, accompanied Will and Jem, up to the York Institute to meet Aloysius Starkweather, who may hold a clue to the Magister's past. Jem gave her the Carstairs family ring, so that she could pretend to be a mundane girl, who was engaged to Jem.
Sophie later came to Tessa with an invitation to a masked ball at the Lightwood's house, addressed to Jessamine from Nate Gray. Jessamine slapped Sophie when she caught Sophie with it, so Sophie hit her and knocked her unconscious with a mirror. Tessa sent Sophie to Will for help, and he placed a sleeping rune on Jessamine so that she would not wake up until morning, and tied her to her bed as a precaution. Tessa Changed into Jessamine, and Will accompanied her, so that she could sneak into Benedict Lightwood's house to attend the ball.
On the balcony at Benedict Lightwood's estate, Tessa and Will shared a rather intimate moment, which was interrupted by Magnus Bane. He was the one who helped them to get back outside of the house.
He realized that Tessa had taken a liking to him and he also realized that he loved her too. Because of this, he went to Magnus Bane, to summon the demon who cursed him. Magnus summoned the demon, Marbas, to release Will from his curse. However, Marbas told them that there was no curse in the first place and swore on it. He told Will that Ella died because she was wounded from the attack. Will was distraught but rushed back to the Institute, jumping with happiness and told Tessa he loved her. His happiness was short-lived as Tessa told him that she was already engaged to Jem. Will, heartbroken, told Tessa not to tell Jem about his feelings and pretended to be happy about the engagement for Jem.
Will trained his sister, Cecily, to become a Shadowhunter. However, he was annoyed at her presence in the Institute and her insistence on him coming home with her, but he did care for her and was fiercely protective of her.
Will discovered that Jem had been taking large doses of yin fen to keep him fit and able, whilst also killing him inside. He traveled to buy more of the demon powder, with Cecily who followed him, but soon discovered that someone had bought it all up.
When Jessamine Lovelace was brought back to the London Institute from the Silent City, the Magister's automatons attacked. Will had no wish to see her, but upon hearing the noise from inside, rushed down to help. He saw Jem run after a carriage of automatons, but did not realize that they had kidnapped Tessa. Jessamine told him that Mortmain was in 'Idris', before dying of a stab wound in the back. Jem returned because the carriage was too fast and he collapsed.
Cecily overheard Will's conversation with Jessamine and figured out that Mortmain was hiding in Cadair Idris, a mountain near where Will used to live in Wales, as she knew Mortmain and his personality.
Will asked Magnus Bane to help them find a cure for Jem, who was dying and running out of yin fen. Magnus asked Will if Jem knew that he was in love with Tessa, but he told Magnus that he did not want to hurt Jem. But Jem overheard them and gave Will his blessing to rescue Tessa, instead of him as he was too ill.
On the road to Wales, Will felt his parabatai rune bleeding, and realized that Jem had died. He throws up and asked Woolsey Scott for advice, even though he got into a fight with some of his werewolf pack. Will cut his hand with Jem's dagger and buried it in the ground by a tree.
He eventually found Tessa in Mortmain's hideout, and rushed to her without thinking, causing him to be trapped inside the invisible barrier with Tessa. Believing that Jem was dead and thinking that they would both die, Will confessed everything to Tessa and told her how much he loved her, leading them to have sex that night.
The next morning, Tessa woke up and realized that her clockwork angel was on his shoulder near his neck, and she pulled it away to find that it had left a mark in the shape of a small white star on Will, thus creating the mark of the Herondales that will be seen on the descendants in the future generations.
Eventually, Magnus Bane found them and released them, bringing them to the others where a battle against hundreds of automatons was being held, with the Shadowhunters losing. Will joined the battle right away and, in the gist of the battle, found out that one of the Silent Brothers, Brother Zachariah, was actually Jem.
Tessa then got captured by Mortmain, threatening Will and the other Shadowhunters with her. Tessa Changed into the angel trapped inside her necklace, Ithuriel, leaving Will in awe as he watched her blaze with fire. She killed Mortmain, but she Changed back into herself afterwards and fell to the ground unconscious, making Will very worried.
They had won the battle, but once Will returned to the Institute with the others, he entered a state of depression because he was worried about Tessa not regaining consciousness, and feeling lost without Jem. Much to his happiness, Tessa recovered and he was allowed a conversation with Jem, which made him feel gloomy for weeks, but he gradually started to recover and adjust to a life without Jem.
Will and Tessa grew closer and, that year during the Enclave's Christmas party, he finally proposed to her, with Tessa saying yes. They planned to get married after Will turned 18, and he used Henry's Portal to go back to Wales along with Cecily, Tessa, and Gabriel to visit his parents after so long. Will and Cecily had a happy reunion with their parents, and Will announced that Tessa was his fiancée. He had a wonderful time visiting his parents after five years.
Eventually, Will became the head of the Institute, a position given to him when Charlotte became the Consul. Eventually, he and Tessa married and, unexpectedly, even had two children: James and Lucie Herondale. After Will retired, he went on to write several Shadowhunter histories which became very well respected.
In 1937, Will, at 76 years old, died of old age. On his deathbed, he was visited by their friends and family, and, finally, Jem, as Brother Zachariah, who came and played him the violin. Jem bade him the Shadowhunter farewell, and Will then died surrounded by the two people he loved most in his life: Tessa and Jem.
|“||You don't know anything about love, do you? They were both so alone, so long. This gives me peace.||”|
Over a century later, Jem and Tessa finally reunited. In 2009, the couple finally got married and tied the knot on Blackfriars Bridge. Will momentarily came back as a ghost to witness the brief ceremony—though it is also possible that he was merely a figment of Jem and Tessa's collective imagination. He joined Jessamine, who also watched the wedding from afar and struck up a conversation with her. They discussed the odd mix of guests, which consisted of Magnus Bane and the descendants of the people they knew. Will also asserted that the thought of seeing Jem and Tessa happy and together again gave him immense pleasure and joy. Shortly after, Tessa and Jem, sensing his presence, approached him and bade him farewell before Will left.
He comes across as rude and arrogant, always utilizing his quick wit and sarcasm. He is aware of his good looks and uses it to get his way. This is in fact a front that he uses to keep everyone at arms-length. He is actually caring and would risk his life for the people he loves. He is also self-sacrificing.
Will reads extensively and has a perfect memory. He can find a quote for almost any situation and often makes his own (very bad, although sometimes purposefully) poetry.
Will is described to have deep violet-blue eyes and black hair that falls in his eyes. He has elegant features—high cheekbones, long, thick lashes, full lips, and an elegant throat, and is often described as extremely handsome by most people. He is said to look amazingly like his mother, Linette. He is muscular and well-built with broad shoulders, and callused hands from his years of training as a Shadowhunter. He is also quite tall at nearly six feet.

|“||I felt I was dreaming and thinking and feeling with you. I dreamed what you dreamed, wanted what you wanted—and then I realized that I truly just wanted you. The girl behind the scrawled letters. I loved you from the moment I read them. I love you still.||”|
–Will, Clockwork Prince
Will's relationship with Tessa is rocky. At first he treats her quite rudely. She is the only one, besides Jem, to make him laugh and he takes a liking to her straightaway. During the fight where her brother is rescued, Will bites a vampire. Back at the Institute, he stays by himself in the attic drinking holy water to get the vampire blood out of his system. Tessa arrives to see how he's doing and he kisses her. At the end of the book, when he realizes that she's dead, he feels empty and as if he's lost everything. When he sees that she's actually alive, he is terrified that he showed too much emotion and that she could see that he cared for her, so he insulted her on the roof when she told him that she would be staying at the Institute. He did this by insinuating that she was a prostitute, and a barren one at that. However, he has his reasons for doing this, which are revealed in Clockwork Prince.
In the second book, they don't talk much but Will, slowly figuring that he's falling for her, goes to find an indifference potion for himself so he can't love her, but he cannot attain one. When they find out Jessamine is a traitor, Tessa disguises herself as Jessamine at the Lightwoods' ball. They kiss on the balcony at the party, only to be interrupted by Magnus. After he finds out that there was no curse on him, he tells Tessa that he loves her but she tells him that Jem already proposed to her. Will tells Tessa to forget everything that he told her. When Jem announces the engagement at dinner, he makes a toast to him and Tessa and pretends to be happy for them.
|“||Jem is my greatest sin.||”|
–Will, Clockwork Prince
When Jem arrived at the Institute, he and Will immediately became friends after he shows that he is not intimidated by Will's moody attitude. It is said that Will spent a lot of time in Jem's room, ensuring that he wouldn't die because of his yin fen addiction. Will did not tell Jem of the curse put on him when he was 12, but has a close friendship with him, like brothers. When they were 14, Will asked Jem to be his parabatai. Jem refused, but when Will put a bet on a sword fight, he agreed.
Before Tessa, Jem was the only person Will truly cared about and showed affection to. He thought that his curse wouldn't affect Jem, since he was already dying. With every passing day that he lived, Will's theory solidified. Will cares for Jem when he is weak and buys yin fen for him from the ifrit's den in Whitechapel because Jem can't face it.
When he found out that Jem loved Tessa and was engaged to her, he sacrificed his love for her and pretended to be happy. He even toasted them when Jem announced it at dinner.
Although Charlotte shows feelings of maternal love towards Will, he claims not to care, for reasons unknown until Clockwork Prince. It is revealed that he does care for her in a motherly way, but is just trying to protect her from the 'curse' that supposedly claimed his sister, Ella.
However, he still has not told her about the fake curse the demon put on him, which resulted in him pushing away those who loved or cared for him.
