Biography
Early Life
Sloane Mairi was born in 614 AU, the daughter of Isaac Mairi and Colonel Mairi and the younger sister of Liam Mairi. Her family was tied to the Tyrrish Rebellion, and after the rebellion failed, both of her parents were executed. Like the other children of the rebellion’s leaders, Sloane was left to carry the consequences of a war she did not start.
After the executions, Sloane was separated from Liam and fostered by another family. This separation becomes one of the defining wounds of her life. Liam is not only her older brother, but the last close connection she has to the family she lost. By the time she enters Basgiath, grief, anger, and loneliness have hardened into resentment.
Liam’s death at Resson shapes Sloane’s entire entrance into the story. She arrives at Basgiath knowing that Violet Sorrengail was with Liam when he died, and she blames Violet for surviving when her brother did not. This makes Sloane one of the most emotionally charged first-years in Iron Flame.
Iron Flame
Sloane enters the Riders Quadrant on Conscription Day in Iron Flame. She crosses the Parapet with a small amount of help from Violet, who discreetly assists her with her hair. Sloane does not thank her for it. From the beginning, she makes it clear that she hates Violet and holds her responsible for Liam’s death.
Her hatred becomes a major source of tension in the squad. Violet made a promise to Liam to look after Sloane, but Sloane refuses to accept help from the person she blames most. She does not want Violet’s protection, sympathy, or guidance, and she initially resists being placed anywhere near her.
Sloane is also badly underprepared for the Riders Quadrant. Unlike Liam, she was not fostered with fighters and does not enter Basgiath with the same combat foundation. Imogen Cardulo quickly recognizes that Sloane is vulnerable and needs training if she wants to survive, but Sloane refuses her help as well.
When Sloane faces Dasha Fabrren in a sparring challenge, Violet quietly intervenes to give her a chance to win. Sloane does not immediately understand or appreciate what Violet has done, but the moment shows how determined Violet is to keep Liam’s promise, even when Sloane makes that promise difficult to honor.
Violet eventually uses Liam’s letters to get through to Sloane. Before his death, Liam wrote a stack of letters for his younger sister. Violet saves them and gives Sloane one letter for every week she agrees to train with Imogen. It is a harsh bargain, but it works. Through those letters, Sloane gets pieces of her brother back while also becoming strong enough to survive Basgiath.
Over time, Sloane’s hatred of Violet begins to change. She learns that Liam did not hate Violet, and that he cared for her deeply as a friend. This realization does not erase Sloane’s grief, but it forces her to see Violet as more than the person who lived when Liam died.
During Threshing, Sloane bonds Thoirt, a red Daggertail dragon. The bond places her more firmly within the Riders Quadrant and gives her access to channeling and lesser magic. She later manifests her signet as a siphon, a rare and powerful ability that allows her to draw power from one source and transfer it into another.
At the end of Iron Flame, Sloane becomes crucial during the Battle of Basgiath. When Violet attempts to imbue the wardstone and nearly burns herself out, Lilith Sorrengail forces Sloane to use her siphon signet. Sloane channels Lilith’s and Aimsir’s life power into the wardstone, allowing the wards to rise and saving Basgiath. Lilith dies as a result, leaving Sloane with deep guilt over the role she played.
Onyx Storm
In Onyx Storm, Sloane is still affected by what happened at Basgiath. Her signet saved lives, but it also made her the instrument of Lilith Sorrengail’s death. Because of that guilt, she resists training her siphoning ability and struggles with the idea that her power can be used to harm as well as save.
This conflict is central to Sloane’s growth. She does not want to be treated like a weapon, especially after being forced into a role she did not choose. Her fear is understandable: siphoning is an ability with enormous consequences, and Sloane has already seen how quickly it can cross the line between survival and sacrifice.
Despite this, Sloane eventually uses her signet again in a critical moment. When Mira needs saving, Sloane channels power from Dain Aetos into Brennan Sorrengail, giving Brennan the strength he needs to mend and save Mira. This moment reframes Sloane’s signet. Her power is not only destructive or dangerous; in the right hands, it can preserve life.
Her relationship with Dain also becomes more important in Onyx Storm. At first, Sloane resents him because of his connection to Liam’s death, but their dynamic slowly shifts. Their tension, anger, and reluctant trust begin to develop into something more complicated, with hints of a deeper emotional bond.
By the end of Onyx Storm, Sloane has grown far beyond the angry first-year who entered Basgiath determined to hate Violet. She is still grieving, still stubborn, and still learning how to live with her power, but she has become one of the Revolution’s most important young riders.
Physical Description
Sloane has blond hair and the same sky-blue eyes as her older brother, Liam. The resemblance makes her connection to Liam immediately clear and adds emotional weight to Violet’s promise to protect her.
She is strong, quick, and has good balance, though she enters Basgiath without the combat training many other marked ones received. Sloane is also about three inches taller than Violet Sorrengail.
As one of the marked ones, Sloane bears a rebellion relic that winds around her arm. The relic marks her as one of the children punished for the Tyrrish Rebellion and connects her visually to Liam, Xaden, Imogen, Garrick, Bodhi, and the other marked riders.
Sloane typically wears standard rider leathers and cadet gear. Her appearance is practical rather than decorative, fitting her role as a first-year rider trying to survive Basgiath while carrying the grief of everything she has lost.
Personality
Sloane is stubborn, emotional, loyal, and deeply shaped by grief. When she enters Basgiath, her anger is louder than almost anything else. She has lost her parents, been separated from her brother, and then lost Liam before they could reunite. That pain makes her defensive and quick to lash out.
Her hostility toward Violet is not simple cruelty. It comes from grief looking for someone to blame. Violet becomes the easiest target because she was there when Liam died and because she is a Sorrengail. Sloane’s anger is unfair, but it is also understandable within the trauma she carries.
Sloane does not like feeling weak or dependent. She resists help from Violet and Imogen because accepting it would mean admitting that she needs the people she wants to hate. This makes her difficult, but it also shows how badly she wants control over her own survival.
Over time, Sloane becomes more open to the truth. Liam’s letters help her understand her brother more clearly, and Violet’s persistence slowly breaks through her assumptions. Sloane does not become soft, but she becomes more honest, more capable, and more willing to accept that survival sometimes requires trust.
Her arc is about learning that power does not have to make her a weapon. As a siphon, Sloane can take and transfer life-changing amounts of energy. Her fear of that ability is part of what makes her human. Her growth comes from realizing that the same power that caused death can also save lives.
Powers
Lesser Magic
Through her bond with Thoirt, Sloane can channel lesser magic. Like other bonded riders, this allows her to unlock doors without touching them, move with preternatural speed, manipulate mage lights, power ink pens, and place runes.
Siphoning
Sloane’s signet is siphoning. As a siphon, she can absorb power from another source — including riders and dragons — and then transfer or imbue that power into something or someone else.
This makes her signet extremely rare and dangerous. Sloane does not simply create power of her own; she redirects power already present in the world around her. In the right circumstances, that makes her capable of restoring wards, strengthening another rider, or helping save a life.
The emotional cost of her signet is just as important as the magical one. At Basgiath, Sloane is forced to channel Lilith’s and Aimsir’s power into the wardstone, leading to Lilith’s death. That moment leaves Sloane afraid of what her signet can do and reluctant to train it afterward.
Abilities
Imbuing
Sloane can imbue power naturally because she is a siphon. Imbuing allows power to be placed into an object or transferred where it is needed, leaving it in stasis or channeling it into another target.
This makes Sloane valuable in situations involving wardstones, magical restoration, and emergency channeling. Her ability is not only useful in battle, but also in moments where survival depends on moving power quickly and precisely.
Rider Training
Sloane begins her time at Basgiath as an undertrained fighter. Unlike Liam, she was not prepared for the Riders Quadrant by someone like Xaden. This makes her vulnerable during sparring challenges and forces her to confront how dangerous Basgiath truly is.
With Imogen’s training, Sloane begins improving. Her progress is hard-won, and much of it happens because Violet uses Liam’s letters to push her into accepting help. Over time, Sloane becomes stronger, more disciplined, and better able to survive the Quadrant.
Relationships
| Liam Mairi | Liam is Sloane’s older brother and one of the most important people in her life, even after his death. The siblings were separated after their parents were executed, and they never reunite before Liam dies at Resson. His letters become Sloane’s last direct connection to him. Through them, she begins to understand the person Liam became at Basgiath and the truth of his friendship with Violet. |
|---|---|
| Violet Sorrengail | Sloane initially hates Violet and blames her for Liam’s death. Violet, however, made a promise to Liam to look after his sister and refuses to abandon Sloane, even when Sloane rejects her help. Their relationship slowly changes through training, Liam’s letters, and shared danger. By Onyx Storm, Sloane no longer sees Violet as simply the person who survived Liam. She becomes part of Violet’s wider circle of allies. |
| Imogen Cardulo | Imogen becomes Sloane’s trainer after Violet bargains with Liam’s letters. Sloane resists at first, but Imogen is one of the few people blunt enough to push her without pitying her. Their dynamic is practical and often harsh, but Imogen’s training gives Sloane a real chance to survive Basgiath. |
| Dain Aetos | Sloane’s relationship with Dain begins with resentment. She blames him for his part in the events that led to Liam’s death, which makes their early interactions tense. In Onyx Storm, their dynamic shifts as they are forced to work together. When Sloane channels power from Dain into Brennan to save Mira, the moment shows growing trust between them. Their relationship carries a slow, subtle romantic tension that develops through anger, guilt, and reluctant understanding. |
| Brennan Sorrengail | Brennan becomes important to Sloane through the use of her signet. In Onyx Storm, she channels power from Dain into Brennan so he can mend and save Mira. This moment allows Sloane to use her siphoning ability for healing rather than loss, helping her see that her power can save lives. |
| Lilith Sorrengail | Sloane is forced to use her siphon signet on Lilith during the Battle of Basgiath, channeling Lilith’s and Aimsir’s life power into the wardstone. The act raises the wards and saves many lives, but Lilith dies as a result. Sloane carries guilt over this afterward, and that guilt becomes one of the reasons she resists training her signet. |
Dragon
Thoirt
Sloane is bonded to Thoirt, a red Daggertail dragon. The bond mirrors Liam’s connection to his own red Daggertail, Deigh, creating a clear parallel between the Mairi siblings.
Through Thoirt, Sloane channels lesser magic and manifests her siphon signet. While Thoirt is not given as much page time as some of the major dragons, his bond with Sloane marks her full entry into the Riders Quadrant and gives her the power that later becomes crucial to the Revolution.
