|“||I hate leaving you. I'd take care of you if I could. You know that, right? I'd take over the Institute. I love you all so much.||”|
Helen Penhallow Blackthorn, also known among fey as Alessa, is the eldest child of Andrew Blackthorn and, along with her brother Mark, is his half-Shadowhunter and half-faerie offspring with Nerissa. She was a former member of the Council and is the wife of Aline Penhallow.
Helen was born to Andrew Blackthorn and Seelie Court faerie Lady Nerissa in 1989. She was followed by her younger brother Mark before their parents got separated. While she and Mark initially remained with Nerissa, she eventually sent them to Andrew at the Los Angeles Institute where they have since been raised and trained as Shadowhunter children. She received her first Mark when she was ten years old.
Despite having a different mother, Helen became very close with her younger siblings and grew up taking care of them. Being the oldest of seven children, she grew used to her life being crazy and hectic, though this has not made her immune to feeling exasperated by her siblings' antics. Nonetheless, she loves them fully.
At some point during her life, she came to the realization that she was bisexual and came out to her parents. They accepted it casually, it seems, allowing her to date whomever she wanted. At some point, she met Aline Penhallow at the Rome Institute while hunting down the Crimson Hand, and the two began dating publicly, much to the Clave's general disapproval.
In 2007, Helen turned 18 and went on her travel year in Europe. At some point during her time in Paris, the warlock Mori Shu sent her a message asking for protection from the cult the Crimson Hand. Instead of granting him protective custody and going to the Paris Institute for help, Helen decided she wanted to take care of this on her own as she didn't want the Shadowhunters to think of her as more of a Downworlder than they already did. So she agreed to meet with Mori in Paris but the cult intervened, sending a group of Iblis demons after them. If it wasn't for Alec Lightwood, who happened to be passing by them in hot-air balloon with Magnus Bane, Helen and her companion Leon Verlac wouldn't have survived. However the incident had spooked Mori Shu and so he fled to Rome.
Still Helen didn't go to the Institute for help. On her way to follow him to Rome, she stopped at Malcolm Fade's party in Venice, seeing as it was held in the cult's previous headquarters. In her investigation of the building, she ran into Alec again. She became extremely suspicious of Alec's presence, as well as his boyfriend and the fact that they had both just come from Paris too. She requested he come with her and Leon to the Rome Institute to answer some questions. Though Leon disagreed seeing as how he had saved their lives and was clearly dressed for the party. Begrudgingly, Helen let him go and they continued their search before moving on to Rome.
A few days later, Helen encountered Alec once again, this time in the exact place he had refused to go with her: the Rome Institute. Upon seeing him, she made him follow her into the records room and began interrogating him as she had initially wanted to. She asked him several questions about the Crimson Hand, Magnus, and what had happened in Venice with Mori's body being found before she was interrupted by Alec's companion Aline Penhallow. The two went back and forth for a few minutes with only a couple interjections by Leon and Alec. Eventually Helen decided to offer Alec and Aline to come with her to a meeting point that the Crimson Hand had used in the past, in hopes of catching Magnus in the act.
On their way to the location they received word from Shinyun Jung to meet them at a different spot based on a more recent informant than Mori, and the three agreed to go there. While they waited for them to show up and they looked around the clearing, Alec realized the occult leader they were looking for was Shinyun. When they attempted to leave they were trapped by Cherufe demons. After fighting off and escaping the fire demons, three of them made their way to the Crimson Hand's headquarters through Alec tracking Magnus.
Together they fought through the cult members and some Shinigami demons, rescued Magnus, captured Shinyun, and put an end to the cult. Soon Shadowhunters from the Rome Institute began flooding the scene and apprehending the remaining cultists. Helen and Aline helped the head of the Institute, Chiara Malatesta, in sweeping the grounds for stray cultists or demons. When they returned they found Alec and a missing Shinyun. They then began plotting what to say to the Clave as far as what had happened without implicating any of them. Before they could discuss who they would claim the leader to be, Aline abruptly asked Helen on a date. Though she was supposed to head to Prague in a few days to continue her travel year, Helen agreed and decided to stay in Rome a while longer to date Aline.
Their relationship grew serious very fast and soon Helen had introduced Aline to her 6 siblings and the pair had exchanged family rings.
When Helen returned from her trip a few weeks later, she had earned herself a seat on the Council as the representative of the Los Angeles Conclave. When Jace Lightwood went missing, the Clave began searching for him and Sebastian Morgenstern. After two weeks of searching, when the Council recommended the deprioritization of the search as there was no evidence that Jace was alive, Helen was among those who voted against it, feeling that they needed to search for Jace. Sadly, they were overruled and the search was deprioritized, anyway, in favor of focusing solely on reinstating the wards that Sebastian had broken.
Some time later at the New York Institute, Helen and her girlfriend Aline were speaking privately with Maryse Lightwood when Isabelle and Alec updated their mother on what they had been up to, particularly that they had found Jace, and Sebastian, as well as some of their plans through Clary. Though surprised, Helen and Aline agreed not to reveal anything to the Clave. Helen even joined the group and helped them in their battle against Sebastian and his army of Dark Shadowhunters at the Burren.
Only weeks after the battle at the Burren, Helen was still staying with the Penhallows in Idris when the Los Angeles Institute was attacked by Sebastian. Only her younger siblings—with the exception of Mark—and Emma Carstairs were able to escape the attack, and it was up to Helen to care for them. They also learned that her father, Andrew, was Turned Endarkened, and Mark, who was not Turned as a result of his faerie heritage, was still captured for some reason; though it was later revealed to everyone that he was captured because of his fey heritage and given to the Wild Hunt as a gesture of goodwill from Sebastian to honor his alliance with the Seelie Queen and her Court.
Upon this realization, in addition to the information they received regarding the timing of Sebastian's attack on Alicante, the Clave prepared the city with elements to protect against the fey, such as cold iron and salt. Because Helen is part-faerie, she was also somewhat affected by these implements, though only slightly. Regardless, she still fought to protect her siblings and Emma while she accompanied them to the Accords Hall, where all of the Nephilim children in Idris were being hidden. After she secured them in the Hall, Helen joined the battle in Angel Square where she tried to get to Aline but the fighting forced her back.
The next Council meeting, held three days after the battle was won, brought up the issue of what to do with Mark and Helen, both of whose loyalties are being questioned only because of their faerie heritage, as well as due to the paranoia following the revelation that Meliorn, also half-fey, could lie. Helen, being eighteen, would have been given permission to become her siblings' legal guardian if not for the circumstances; this was disregarded even further when her uncle Arthur arrived and accepted the position as head of the Institute and guardian of the Blackthorns.
Despite Helen's steadfast loyalty and devotion to both the Shadowhunters and her family, and due to the intense desire for vengeance against the fey and anyone with faerie blood, the majority of the Clave members still opted to punish her and her brother; Helen, found to be not needed with regards to raising her siblings, was exiled to Wrangel Island in the Arctic to study the wards indefinitely while the matter was further investigated, and the search to rescue Mark from the Wild Hunt was abandoned as well. Heartbroken, Helen was left with no choice but to accept and trust that her uncle Arthur would be able to care for her siblings. Before she left for Wrangel Island, she said her goodbyes to her siblings and Emma, and told her brother Jules to look after what remains of their family. Her girlfriend Aline also promised to follow her to Wrangel Island the following week, after the post-war Council meetings had commenced.
Helen eventually proposed to Aline, and the pair became engaged. They planned to get married in Idris with their friends and families on the first of October in 2009. Aline's mother, being the Consul, made this possible by convincing the Clave to allow them to temporarily leave the island and stay in Idris for a whole day for their wedding. In exchange, Helen would be paraded around the Shadowhunter Academy as a lesson for their students against faeries. Helen agreed.
Upon her arrival at the Academy, she was greeted with disgust and contempt and fear, just as the Clave had hoped for. Helen was forced to tell the students the story—albeit a false one—of her parents, which she had also just found out—a story that also devastated her and made her momentarily doubt her nature. One of the students Simon Lewis, however, was more intimately familiar with Helen through Clary and did not despise her. Additionally, Isabelle had Helen fetch Simon for her, and Helen asked Catarina Loss to send Simon to her room. After a brief conversation with Simon, she sent the couple off to their date.
Helen later returned to Idris, this time with Aline for their wedding. Their friends and family had arrived, and Helen's suggenes was Jules. After the ceremony, Simon came to hug her and passed on a message from Mark which brought her to tears.
Helen was able to make the most out of her exile on Wrangel Island as she developed a genuine interest in the wards. With her determination and focus, she is well on her way to becoming one of the foremost experts onwards, and she hopes that her knowledge would convince the Clave to allow her to come home. Nonetheless, she continued to struggle with her separation from her family, and though she remained in constant communication with them, Jules kept her oblivious to her younger siblings', particularly his, own struggles at the Institute.
Unable to return home still when Mark was returned to the Los Angeles Institute, Helen had to settle with speaking with him over the phone.
In 2012, Helen and Aline detected when the former High Warlock of L.A. Malcolm Fade broke the wards of the L.A. Institute and immediately reported it to Jia. Around this time, they also saw the earliest signs of the Shadowhunter blight on the maps of Alicante, in the area of the Brocelind Forest, and informed Jia about it.
Knowing what they knew, Diana Wrayburn—the tutor of Helen's younger siblings—plotted with Jia to have Helen and Aline present at the Council meeting that would discuss the blight and potentially present themselves as the new heads of the Los Angeles Institute, a position that was vacated by Arthur's death. While Jia could not even consider it because of the complications of Portal travel to and from Wrangel Island, Diana found a way, allowing Helen to reunite with her siblings. At the meeting, Helen was unable to get to her younger sister Livvy in time to stop Annabel from killing her.
In the chaos caused after Annabel murdered Livvy and Robert Lightwood and Horace Dearborn was able to rise to power as the new Inquisitor, Jia assigned her daughter as temporary head of the Los Angeles Institute. Thus allowing Helen, as her wife, to return home and end her exile. The pair returned home along with Mark, Dru, Cristina, Ty, Kit, and Tavvy to avoid interrogation by Horace.
Once home, Helen found herself struggling to reconnect with her younger siblings. As they were all still mourning the loss of their other sister, they were moody and either wished to be alone or with Julian — the one who had raised them and been there for them all these years. They considered Helen as more of a stranger than another sibling and she found herself at a loss of what to do. Helen eventually had a breakthrough with her siblings after a night of easing Tavvy's nightmares and comforting Dru after she broke down about people leaving. From then on her siblings stopped being so cold to her and they started getting to know each other better.
When The Registry was passed, Helen and Aline devised a plan to undermine it while still fulfilling their quota. They ended up giving the Downworlders' fake names—often belonging to a mundane celebrity—so that while they were technically registered, the Clave wouldn't be able to find them.
A few days later Cristina, Mark, and Kieran returned from their rescue mission in Faerie with Jace and Clary; followed a few moments later by Julian and Emma who were visibly injured and dressed oddly. When Emma came back to consciousness a few days later, Helen was the first to burst into the room and hug her. After Julian and Emma shared their account of Thule, Helen took charge in getting the group to focus and plan what they needed to do about the blight.
A few days later Julian had called a war council, surprising Helen that he was able to get in touch with so many Downworlders and Nephilim. Regardless, Helen supported his plan and helped set up the Sanctuary for their visitors. After the meeting Helen Portaled with the rest of the group to Brocelind Forest and the following day she was part of the group that had stayed behind expecting to be ambushed by Dearborn's followers.
Following the ambush, Helen, along with the others who had stayed behind, marched the group of followers onto the Imperishable Fields in the middle of the Cohort's parley. Soon battle broke out and Helen fought alongside her wife, later uniting with Jia. And when Julian and Emma rose up as True Nephilim, Helen was among those who tried to talk them down from their giant state; only succeeding when Dru and the others joined them.
A few weeks after the Clave being sentenced to exile, Helen and Aline were officially named as heads of the Institute. At Magnus and Alec's surprise wedding party, Aline told Helen that she would like to have a baby. Helen was very excited by the idea, saying their child would be like a little sister or brother for Ty, Dru, and Tavvy. Though when Aline suggested that they should name her Eunice (if it was a girl), Helen firmly said no.
Personality and traits
Helen is a kind, compassionate, and loving person, as well as loyal and responsible. Helen considers others, even those she does not know, in her decisions.
Helen Blackthorn is pale, beautiful, and petite, with her faerie blood contributing to her loveliness. She has pale, white-gold hair that falls in ringlets and is often tucked back to show off her pointed ears. She also has the trademark blue-green eyes of her family.
Skills and abilities
- Nephilim physiology: Being Nephilim, Helen possesses a variety of enhanced physical and mental abilities granted to her by the angel blood of Raziel in her veins and also by the angelic Marks of the Gray Book. This includes enhanced strength, speed, agility, stamina, and coordination, which continue to improve over time and practice.
- The Sight: As a Shadowhunter (and half-faerie), Helen is naturally and easily able to see through most magical illusions and layers of glamour over reality.
- Runic magic: Due to the angel blood in their veins, all Shadowhunters are able to apply runes on their skin without any real danger. These Marks, in turn, give varied effects that serve to benefit the wearer.
- Use of heavenly weapons: As a Shadowhunter, Helen is also able to perform tasks unique to their species, such as the ability to use and call on the power of angels for their seraph blades, as well as to handle any heavenly weapons or objects with effect, which would normally not work for other species. In particular, these are tools made of adamas and forged by Iron Sisters.
- A nonelectric coffee maker that Magnus magicked up which can vaguely be defined as a parting gift from the time when Helen and Aline left for exile in Wrangel Island.
|“||She is the light of my days.||”|
Aline is Helen's wife. The pair met while Helen was on her travel year in Rome, shortly after the Mortal War. Their first meeting was slightly confrontational but after an adventurous day of fighting demons and ending a cult, Aline asked Helen out. Helen agreed, deciding to extend her stay in Rome to date her.
Weeks into their relationship, they were already committed enough that they exchanged family rings—a pretty serious gesture between Shadowhunters, similar to mundane engagements. When Helen was exiled to Wrangel Island, Aline followed, and Helen soon proposed. They were eventually allowed to get married in Idris, but were forced to return to exile the following day.Three years later, Helen and Aline were finally able to return home and took over running the LA Institute and raising the kids. Helen initially struggled with reconnecting to her younger siblings but with Aline's support—and scoldings to the kids themselves—they were able to break through that barrier. In a few weeks, they got their groove as parental figures and began discussing possibly having a baby of their own.
Being the eldest of seven children, Helen grew responsible for her siblings, five of them her half-siblings, and loved them nonetheless. She seemingly has a good relationship with all of them and deeply cares about them. When it was decided that she would be exiled and would be separated from them, she was incredibly heartbroken and terrified at the prospect of leaving them.
Though Jules was only twelve at the time she was forced to leave, she trusted him to look after the others, being the eldest left as even Mark was absent and stuck with the Wild Hunt. She specifically asked him to pay special attention to Ty.When she returned from her exile years later, she struggled to reconnect with her siblings. Eventually, she had a breakthrough and was able to repair their relationships. She immediately took over for Julian as their guardian.
Andrew is Helen's father who raised her and Mark as Shadowhunters at the Institute despite their heritage. When she learned of the news that the Institute was attacked, and that her father was Turned into an Endarkened, she was horrified, even more so after he was later killed in Idris by no other than her younger brother, Jules. Helen and her siblings mourned their father's death.
Arthur, Helen's uncle, became the new head of the Institute and the guardians of her siblings and Emma after the events of the Dark War. Helen was then forced to trust that he would take care of her younger siblings, and believed that he seemed like a nice enough man.
Helen is good friends with Alec, and the pair became acquainted through Aline, who is childhood friends with the Lightwoods.Alec voted against sending her away to Wrangel Island to study the wards along with a few of the Council members.
Emma is a family friend of the Blackthorns and Jules's best friend. Helen seems to care for Emma just as much as her siblings.When Emma's parents died, it had been Helen who broke the news to her and witnessed her break down. Helen was very concerned and tried to console her.

- Helen was in the middle of her travel year in The Red Scrolls of Magic.
