Ghislaine Blackbeak was an Ironteeth Witch of the Blackbeak Clan and was the eldest and cleverest member of The Thirteen.

Physical Description

Ghislaine looked young and beautiful with curly black hair, brown skin, and sea-green eyes.


Most notable among Ghislaine's personality traits was her razor-sharp intelligence. She enjoyed reading and researching, and she often served as a source of information for Manon. If interrupted while reading, she tended to become irritated and snarky. On the battlefield, however, she fought expertly and obediently. Her battle prowess and her brains combined made her a formidable member of the Thirteen.

Her twelve years at mortal school caused her to pick up and cling onto some human behaviors and gestures.

It had been an exception when Ghislaine's mother convinced the High Witch to send her daughter to a mortal school in Terrasen a hundred years ago. She had learned magic and book-things and whatever else mortals were taught and when the witch had returned twelve years later, the witch had been different from the others - still a bloodthirsty Blackbeak, but more human than the rest. She had a sense of impatience, of life clinging to her.


Some time before the series began, Ghislains joined The Thirteen.

Heir of Fire

Ghislaine is introduced in Heir of Fire as one of Manon’s Thirteen. Like the other Ironteeth witches, she learns how to be a wyvern rider.

Queen of Shadows

After winning the War Games, Manon and the Thirteen are sent with half the Ironteeth witches to Morath to assist Duke Perrington. After four weeks in Morath, Manon and the Thirteen become suspicious of the strange goings-on and are grating against Duke Perrington’s orders. On his order, Manon takes her Thirteen hunting for people living in areas new Morath. 

The Thirteen take Kaltain Rompier, Duke Perrington, and his men to a tribe in the White Fang Mountains and Kaltain tortures them with her shadowfire. Duke Perrington then has the Thirteen slaughter the tribe. 

Manon comes to Ghislaine who is reading in her room to learn what knowledge she might have from her schooling in Terrasen regarding the Valg. Ghislaine begins explaining, but upon seeing Manon's eyes glaze over with boredom, Ghislaine summarizes the information. She tells Manon about how witches are the products of the Fae and the Valg. She says that the Ironteeth witches take more after their demonic ancestors, while the Crochans take after the Fae. When Manon asks if the Valg are potential allies, Ghislaine shows dismay and reluctance at the idea. She explains that the Valg have no laws or codes. They would see the Thirteen as weak for their bonds and rules, making them something to break for amusement. Manon confirms that the scent she's been smelling is the Valg inside their human hosts. Ghislaine also tells her that the word "allies" doesn't exit to the Valg. That they find the alliance useful, but will honor it only as long as it remains that way. She turns pale when Manon tells her about the duke's desire to experiment in creating Valg-Ironteeth children. Ghislaine finishes by telling Manon that the witches are wicked, but that legend says the Valg are the origin of evil. "They are blackness and despair incarnate."

The Thirteen are meeting when they’re interrupted by a man with a Valg inside him. He attacks them with darkness and mental pain. Manon kills him while the human trapped inside, Roland Havilliard, begs for death. Manon looks on in horror at the effect that the Valg powers have on those among the Thirteen without golden eyes. Ghislaine is sobbing in the corner and screaming in pain.

The Thirteen meet the King of AdarlanDorian Havilliard, and the Blackbeak Matron in Oakwald Forest

The Thirteen barely escape the explosion caused by Kaltain that destroys one-third of Morath, which includes the destruction of the evidence of the Thirteen’s actions. The Thirteen drop Elide Lochan off in the Oakwald Forest and send her on way before returning to Morath. The Thirteen decide to stay at Morath until the Matron arrives and then they will decide what to do.

Empire of Storms

Manon and the Thirteen tensely greet the Blackbeak Matron and her coven at Morath. The Thirteen are sent on a mission to take control of Rifthold and bring Dorian Havilliard, now king, to Erawan if he survives. They are also ordered to destroy the glass wall Aelin Galathynius made surrounding the palace. Before leaving for Rifthold, Manon tells the Thirteen not to let anyone kill Dorian. Manon asks Ghislaine to quickly tell her and Asterin a brief history of who Erawan is.

At sunrise, the witch killing ceremony starts. The Thirteen give Manon the gesture to honor a Witch Queen. Muttering ripples through the crowd and Manon knows that she can't allow this death to happen. She screams at the Thirteen to run and whirls to kill her grandmother instead. The Thirteen are able to escape on their wyverns.

The Thirteen arrive at the beach in Eyllwe and join in the battle against Maeve's armada. They help Rowan and the group win the battle. The Thirteen is reunited with Manon afterwards. Manon asks them if they heard the truth about her parentage and if they will still follow her. Asterin tells her that they will, and once again the Thirteen give her the gesture honoring a Witch Queen. Manon declares that they must become better than their foremothers. Manon, the Thirteen, and Dorian promise the group that they will find the third Wyrdkey and the Crochan witches to unite them to fight with Aelin.

Kingdom of Ash

For the past two months Manonthe Thirteen, and Dorian Havilliard have been hunting for the Crochan witches. They are currently in the White Fang Mountains. Manon is worried that Dorian might have to be the sacrifice to forge a new Lock.

The next day the group is preparing to move on when Manon is attacked by a mighty, white bear. Dorian freezes the creature with his magic and it shape-shifts into a Stygian spider. The spider is Cyrene, the spider who Manon encountered to get spidersilk for Abraxos’ wings. She tells Manon that she tracked her scent using her belongings left at Morath. She says that there are Crochan witches nearby.

Cyrene leads the group to the Crochan witches who greet them with mistrust. Glennis Crochan introduces herself as Manon’s great-grandmother. When two Yellowlegs covens attack, Manon, the Thirteen, and Dorian, help the Crochans kill them, which gains them some trust. Dorian realizes that Manon deliberately attracted the Yellowlegs to try and gain the Crochans’ trust. Manon and Dorian explain that they are there to ask the Crochans to fight against the Ironteeth witches and Erawan’s army.

Glennis tells her that only a Crochan Queen can summon them to war, and Manon has not been accepted. She says that they are on their way to Eyllwe to answer a call for aid by the southern hearths. The group and the Crochans are delayed for a week while they heal from the Yellowlegs attack. When the group is too late arrive in Eyllwe, Ghislaine helps bury the dead, earring some more respect from the Crochans.

When the Thirteen and Manon go to the Ferian Gap to speak to the witches under Petrah Blueblood's command, Ghislaine cries when Asterin tells her story. Back at the Crochan camp, a Crochan scout reports that Terrasen has sent out a call for aid. Manon, as the Queen of the Crochans, spreads the Flame of War to call all Crochan witches to aid Terrasen in the fight against Morath.

Orynth readies for battle as the Ironteeth aerial force approaches, 1,000 strong. Fortunately, Manon arrives at the same time with the Thirteen and 5,000 Crochan witches. The surprise buys them a day. The next day during the battle, Abraxos is hurt and Manon is unable to stop the Thirteen as they sacrifice themselves by performing the Yielding in order to bring down the final witch tower before it can destroy the castle. Ghislaine is the third to go down.
