Brennan Sorrengail

Brennan is changed from Violet’s memory, with close-cropped brownish-red curls, sharper facial angles, and tiny lines around his eyes. His smile, eyes, appetite, dimple, and problem-solving tilt remain recognizable to her.

Professor Kaori, who taught both Sorrengail siblings, remembers Violet and Mira’s older brother as a spectacular rider and a good man. Violet’s grief sharpens at the thought that he would not have wanted anyone to die trying to save him.

Violet remembers her older brother as someone who cared more about doing the work than celebrating its completion. On Reunification Day, she thinks he would have hated the party held on the anniversary of his death.

Brennan says he stayed away from Navarre because he could not safely live behind its wards while innocents died to dark wielders or fly for a kingdom that hid the truth. He admits that he has questioned every day the choice that left Mira and Violet believing the lie.

As an Assembly officer, Brennan can hold a hard strategic line even against Violet and Mira. He refuses the first plea to defend Samara and argues that rushing untrained cadets into enemy territory would cost too much, though the choice strains his bond with both sisters.

Brennan reverses that refusal before the battle at Basgiath. He arrives with the fliers, admits he knew he had chosen wrongly as soon as Violet and Mira left, and tells them he will never again leave them to fight alone.

Brennan supports Violet’s mission to find Andarna’s kind because Aretia needs another of that breed to fire its wardstone, but he does not want Violet put in danger. He has already asked to go with her and been refused, and Mira’s accusation that he is sacrificing family for the greater good visibly wounds him.

Brennan scolds Violet for pushing herself from bedbound recovery into burnout, but he keeps mending her overworked muscles. He says withholding help would require him to tolerate seeing her in pain, which he cannot do.

Violet and Mira’s older brother remains one of the central losses in the Sorrengail family. Violet believes his death worsened their father’s health, and no one in the household has dared mention him or his dragon since they died.

Dain helped Violet hold herself together after her brother’s death. That loss is part of the history behind Violet’s early reliance on him.

Violet’s memories of her older brother are affectionate as well as painful. She calls him awesome, remembers growing up around him, and recalls hiding behind him when she was frightened by their mother after a long night near the eastern border.

Brennan appears to Violet after she wakes in Aretia, making the brother she believed dead part of Xaden’s hidden side of the war. His welcome places him with the revolution rather than with Navarre’s official account of the rebellion.

Brennan apologizes to Violet for letting her believe he was dead and says it was the only way. He has followed enough news from Basgiath to know she survived Threshing, and he mended her after Xaden brought her to Aretia stabbed and dying.

Brennan’s survival becomes one of the secrets Violet finds hardest to keep from Mira. Violet thinks Mira and Brennan were inseparable as children and feels that Mira should know he is alive and healthy.

Mira learns Brennan is alive in Aretia and punches him after six years of believing him dead. Their argument centers on his choice to help the Continent while leaving his sisters with the lie, with Brennan saying he chose the greater good and Mira calling him a coward.

Brennan’s relationship with Lilith is openly hostile after he reveals himself alive to her. He says all three of her children stand against her and later answers Violet’s concern for Lilith by saying their mother had no trouble sending any of them to their deaths.

Lilith’s sacrifice leaves Brennan devastated. He is too depleted to stop her, catches her when she falls, covers her body with his flight jacket, and emerges with Violet and Mira in shock while still trying to give orders.

Brennan steps between Violet and Aetos when Aetos tries to punish her directly. He calls Aetos unfit for Lilith’s desk, steadies Violet after she learns Aetos has been made commanding general of Basgiath, and makes Aetos recognize that he has been alive the whole time.

Brennan is one of the people who knows Xaden is turning venin. He has tried to mend Xaden and later quietly stops Mira from attacking when she learns the same secret, worsening Mira’s shock that both siblings kept another life-altering truth from her.

When Violet is found in the courtyard before dawn after Xaden disappears, Brennan takes charge of the report around her. He keeps Weilsen quiet, dismisses him when he treats Violet as a way to locate Xaden, checks whether Violet knows where Xaden is, and asks permission before opening the Dunne-sealed parchment.

He is also remembered as a brilliant strategist. Violet expects that reputation to shape how others judge her when she enters the Riders Quadrant.

Violet’s older brother was a mender, and she believes he would have become one of the greatest menders had he lived.

Brennan’s mending is not merely a remembered signet. Xaden explains that Violet was mended rather than healed after Resson, confirming that Brennan used that ability to save her.

Brennan uses Aretia’s map to brief Violet on the venin advance and judges that Felix’s one-year estimate may be too optimistic. Based on wyvern numbers and territory, he believes the venin could challenge Navarre in six months or less.

Brennan knows Tyrrish because his father taught it to him, but he does not know Old Lucerish. That limitation keeps him from translating Warrick’s wardstone account on his own.

Brennan can speak Krovlish and uses it while negotiating around the Cordyn fliers. He is also able to act as Aretia’s officer representative in bargaining for the luminary.

Brennan’s mending can address severe battlefield injuries. At Medaro Pass, he blocks much of Ridoc’s pain, removes two broken arrows from Ridoc’s abdomen, and gets him moving toward evacuation.

Brennan says mending has limits: he cannot mend magic, relics, or probably runes. A broken wardstone surprises him enough that he does not rule out trying to mend the physical stone.

Brennan succeeds in mending Basgiath’s broken wardstone into one standing piece. The effort nearly empties him, and he can only tell Violet to try imbuing the repaired stone to learn whether it can hold power.

Brennan’s medical practice includes both signet mending and practical healing support. After Violet returns injured to Basgiath, he mends stressed ligament and swollen knee tissue, brings arinmint from Aretia to steep in milk, and invokes the Basgiath Code of Conduct to justify his access as a mender.

Brennan cannot mend Xaden’s venin condition, even after trying every day Xaden was in Aretia for a week. He and Xaden have also tried temple offerings, pushing magic back into the earth, and sitting with the eggs in the hatching grounds without success.

During the attack on Aretia, Brennan gives Xaden a concise tactical picture of the city’s defenses. He accounts for patrol dragons, available retired and active riders, absent officers, ward status, and the best placement for officers, older riders, and cadets.

Brennan acts as tactician in the Assembly chamber before the rescue at Draithus. He presses for a scaled projection, demands defensive details, forces Violet to choose one objective, identifies how Theophanie shaped the trap around Violet and Xaden’s priorities, and proposes a plan built on caches, the armory, Xaden’s trust, and Violet’s obedience.

Violet’s older brother left behind a survival journal written for Mira before she entered the Riders Quadrant. Violet receives it years later, and his handwriting and humor make the old grief feel fresh.

The journal gives practical advice for surviving Basgiath. Its Gauntlet guidance values staying alive over performing well, telling a cadet to use the ropes if necessary because finishing last is better than dying.

A later page of the journal explains that dragons channel only when they decide a rider is ready. The warning prepares Mira for the timing of channeling and the need to be ready when a signet manifests.

Page seventy of the journal says Violet should be kept from the Riders Quadrant and placed in the Scribe Quadrant because she would never be able to take a life.

The Book of Brennan continues to give Violet actionable second-year guidance. It helps her anticipate Sloane’s first challenge and warns that second year includes a course he can only describe as hell.

Brennan takes charge of Warrick’s journal for safekeeping after Violet corrects the wardstone translation. He praises her for retranslating instead of quitting and keeps the preserved account with the Assembly during the emergency.

Brennan’s med kit travels with Violet’s expedition as practical medical supply. Its Lorin salve can treat Xaden’s inflamed gash, and its dried arinmint gives Violet a useful offering during the dangerous dinner with Hedotis’s triumvirate.

Professor Kaori tells Violet that Naolin died trying to save her older brother with siphoning, but the attempt failed because he was already too far gone. The account leaves Violet grieving both her brother and the rider who died for him.

Violet says Fen Riorson killed her brother at the Battle of Aretia. That version of his death is part of why she once needed to read Fen’s name on the execution death roll.

After Violet is wounded at Resson, Xaden rejects Basgiath as the place to save her and rides for someone closer who may be able to help. A familiar but unplaced voice calls Xaden’s name and says he has to save Violet.

The person Xaden sought is Brennan, who has survived in Aretia. His appearance overturns the accepted story that he died in the rebellion.

Brennan explains that Naolin did not fail to save him, though the effort cost Naolin everything. Brennan woke near Aretia with Marbh wounded but alive, and dragons hid them in the valley’s cave network before they sheltered among civilians who had survived the scorched city.

After the venin arena attack in Cordyn, Brennan leads Aretia’s side of the negotiation with Tecarus. He accepts the final deal for the luminary and one hundred flier cadets, requiring every flier brought to Aretia to bring a cross-bolt.

Brennan organizes the Medaro Pass ascent after the luminary reaches Aretia. He pairs rider squads with equal-strength drifts and makes the exercise a threshold meant to create enough mutual respect for riders and fliers to train together.

Brennan and Xaden reorganize Aretia’s combat squads as the war effort expands. Brennan also secures an Assembly deal that lets Aretia supply drifts on a one-for-one basis while producing enough alloy-hilted daggers for every rider.

Brennan publicly reveals himself alive to Lilith during the meeting over Melgren’s offer. He says the movement rules by committee, rejects defending a kingdom that sacrifices neighbors and children, and refuses Melgren’s proposal even if Navarre may not survive two weeks.

During the battle at Basgiath, Brennan works in the ward chamber while the defense depends on his mending. He rejoins the broken wardstone into one standing piece, making Violet’s ward-raising attempt physically possible even though the stone still has to hold power.

Brennan waits in the ward chamber during the secret operation to alter Basgiath’s wardstone so gryphon fliers can wield safely under its protections. He directs the others, tells several riders not to touch anything, and is present in case the stone needs mending again.

At Draithus, Brennan takes over pressure and mending on Mira’s slashed throat but finds the damage too extensive on his own. Sloane transfers Dain’s power into him, allowing him to finish the messy mend, keep Mira alive, and leave a thick pink scar across her throat.

After the field rescue, Brennan cares for Teine at the top of the pass while Mira survives nearby. His care helps move both Mira and Teine out of the immediate battlefield crisis.
