Iron Flame Summary, Characters and Themes

Iron Flame is the second novel in the Empyrean trilogy, a fantasy series by Rebecca Yarros. It follows the events of Fourth Wing, continuing the story of Violet Sorrengail as she navigates a world of dragons, warfare, and political intrigue. 

Violet, now a powerful dragon rider, faces new threats and challenges, both on the battlefield and in her personal relationships. The novel delves deeper into the complex world of the Empyrean, exploring its history, magic, and the intricate relationships between humans and dragons.


Iron Flame resumes immediately after the events of Fourth Wing. Violet is reeling from the revelation that Xaden is part of a secret rebellion, her brother Brennan is alive and leading it, and the venin are real. Navarreā€™s leadership has been hiding the truth to protect its citizens.

At Basgiath War College, Violet faces challenges from the new vice commandant, Major Varrish, and grieves for her fellow Athebyne survivors who are being murdered. She distances herself from Xaden due to his lack of transparency and secretly researches the First Six who raised the wards against the venin.

Violet enlists Prince Cam’s help under the alias Aaric Graycastle and confides in her scribe friend, Jesinia. She struggles with keeping the truth from her loved ones and endures a grueling Rider Survival Course.

Violet’s attempts to uncover secrets lead her to the Archives, where she finds journals of the First Six. However, she is caught by Nolon, who turns her over to Varrish for torture. Xaden arrives to rescue her with Dain’s help, and they expose the truth to the students, leading to a mass desertion to Aretia.

In Aretia, Violet works on translating the journal and raising the wards, while dealing with the growing threat of the venin. She embarks on a mission to secure a luminary from Viscount Tecarus, encountering Xaden’s ex-betrothed, Cat. Tensions rise as Violet discovers Xaden’s hidden second signet.

Violet’s attempts to activate the wards fail, and she seeks Dain’s help in translating the journals. 

A vision reveals that someone in Basgiath plans to sabotage the wards. Violet and her supporters rush to defend Basgiath, but Jack Barlowe, revealed as a venin, destroys the wardstone.

A fierce battle ensues as the venin attack. Violet’s squad suffers casualties, and she unleashes her lightning power to protect them. With the help of a new translation, Violet realizes the need for seven dragons, including Andarna, to activate the wards.

In a desperate attempt to save everyone, Violet prepares to sacrifice herself, but her mother, General Sorrengail, takes her place. The wards are successfully activated, repelling the venin. However, Violet discovers Xaden has turned venin in the process of defeating the Sage.
