Gideon Arthur Lightwood was born the eldest of three children, the others being Gabriel Lightwood and Tatiana Lightwood. Their mother died when he was five years old, and the story of her death that their father told them never made sense to him. Raised by their father, Gideon and his siblings grew up believing all Shadowhunters were like Benedict, who flouts convention and the Law, and they all acted like it. Gideon, however, had apparently never been happy in London, calling their home a miserable place ever since his mother's death.
Gideon was about fifteen when he met Will Herondale at a Christmas party held at the London Institute. His sister, Tatiana, was hopelessly infatuated with Will. When Will humiliated her by reading her diary in front of the entire Enclave, Gideon and Gabriel developed a deep loathing for Will, and Gideon was apparently much worse than his brother during these days.
When he completed his Shadowhunter training at eighteen, Gideon opted to travel to another Institute and settled in Madrid, Spain. Gideon was shocked to realize that all Shadowhunters weren't as pompous as his father and was apparently treated like a monster until he realized the wrongness of the principles he was brought up with and changed his ways.
Return to London
Around a year after he left, Gideon was called back from Madrid by his father, told that he was needed at home and must return immediately. Though he no longer agreed with his father's decisions and principles and wanted to stay away, he decided to return to London, if only in hopes of helping and saving his brother, Gabriel, from their father's further brainwashing.
Before Gideon's arrival in London, it was decided at a Council meeting that he and his brother would be charged with the responsibility of training the untrained residents of the London Institute, particularly Sophie Collins and Tessa Gray.
At one point, his father threw a party at their Chiswick manor to honor, and impress, the Magister. Seeing the demon guests and automaton servants, it was only then that Gideon realized just how far Benedict had gone in terms of his fraternization with demons, much to his horror. He also eventually learned of his father's worsening condition due to his illness, the demon pox, as well as Benedict's deal with Mortmain in an attempt to heal himself.
During the training sessions at the Institute, though the brothers were initially frustrated with the assigned task, Gideon found himself enjoying the company of the servant Sophie, whom he personally trained. The two grew to be very close. Meanwhile, Gabriel continued to antagonize Will for their previous altercation, but Gideon was now fairly calmer about it, having moved past the issue.
Still disgusted and disturbed by his father's actions, Gideon decided to share his information on Benedict with Sophie after meeting with her for a picnic at Hyde Park, wanting to gain her trust and favor. At that point, Gideon had begun to express his feelings for her a bit more openly, though he constantly failed as Sophie still felt skeptical about forming any sort of relationship with him, given their social statuses and his father's indiscretions and challenges against the Institute.
He and Sophie began to meet when the latter wasn't working. When the Shadowhunters of the London Institute needed someone to watch the Institute while they were out, Sophie recommended Gideon. He then became the one that they often called when needing someone to watch the Institute.
Before Tessa and the rest of the Institute left to meet Nate Gray (under the guise of Jessamine) Tessa had caught Gideon and Sophie sharing an intimate moment in the hallway, worrying Tessa and prompting her to warn Sophie about him. Gideon was murmuring into her ear and brushing strands of her hair away from her face. He and Sophie watched the Institute while the others were gone.
After Nate's death, Gideon revealed the new found secret about his father to Sophie and explained the reason behind Benedict's association with Mortmain. Just before Charlotte was about to hand over the Institute to Benedict, Sophie revealed that to everyone at the Institute. He was present when Charlotte, Tessa and Will arrived to the Lightwood manor to confront his father. When the members of the Institute came to blackmail his father, Gideon sided with them in the confrontation. He feared the future of the Enclave, the London Shadowhunter force, if his father became head of the Institute. Then he left with the Institute Shadowhunters, deciding to take up residence at the Institute. He stood up to his father after finding out that his mother died from contracting the Pox from him, making him responsible for her suicide, and for lying to him about it his whole life. This essentially ended his relationship with his father. Benedict was then blackmailed into retracting his request for the London Institute. He tried to convince his brother Gabriel to join him at the Institute, but he refused it out of shame and loyalty to his father. Gideon was disappointed by this, but implied his brother was always welcome to join him, convinced that eventually Gabriel would see the reason. He sat with the Institute Shadowhunters at the Council meeting.
By moving into the Institute, Gideon strained his relationship with Sophie Collins, who didn't think their flirtation could continue while they were living under the same roof. She didn't want him to see her working as a maid, and since he now resided at the Institute she had to serve him. However, Gideon was still very much in love with Sophie, and asked her to bring him scones so that he could see her. Meanwhile his father had succumbed to demon pox, resulting in his transformation into a giant worm demon, and unfortunately he had to slay his father. He then returned to the London Institute with his brother, Gabriel, who assisted him and the Institute in the killing. After delivering scones to him one evening, Sophie comforted him about the loss of his father, but noticed all the previous scones hidden under his bed. Gideon explained that he used the scones as an excuse to see Sophie and that he didn't think of the extra work she had to do in order to make them. Furious, she left. Gabriel then teased him, and Gideon threw a scone at him.
He and Gabriel were then approached by Consul Wayland, who asked them to intercept Charlotte's mail and tell him who she was corresponding with, in fear that she was becoming defiant. Gideon and Gabriel agreed, but sent the Consul false information, talking about her many floral hats and her lack of feminine care regarding her uncle's illness. Sophie caught them, and before she reported them, Gideon explained that he was protecting Charlotte. He then showed Sophie their letters and she laughed, and all their earlier tension was resolved. He later declared his love for Sophie and his intention of marriage in front of everyone. However, she demanded a proper proposal where he asked her. He then recited a heartfelt proposal, which she accepted. In Cadair Idris, Gideon fought alongside Gabriel and returned alive. He later was present for Sophie's Ascension, where he watched proudly and was noted to be clapping the loudest.
Gideon is said to be very attractive; he is very muscular and has thick, sandy-blond hair and grayish-green eyes. He is noted to have gained the most looks from his father.
Personality and traits
Gideon is exceptionally different from the rest of his family. Like his mother, Gideon is mature and kind-hearted, as well as quiet in nature and typically calm. He is known to be a fairly good teacher to Sophie and he is far less rash than his brother. He is shown to care very deeply for his brother, returning to London, though he hated his father's home, just to help his brother. He speaks Spanish when he is in a good mood.
