Maas crafts a narrative filled with battles, political maneuvering, character growth, and romantic developments, particularly between Aelin and Rowan.

Yes, reading the previous four Throne of Glass books is essential before starting Empire of Storms by Sarah J. Maas. The novel directly continues storylines established in earlier installments, including Aelin's defeat of the King of Adarlan, the revelation about Valg possession, and her complex relationships with characters like Rowan, Dorian, and Manon. The book references life debts, past alliances, character transformations, and magical developments that require context from previous novels. Without this foundation, readers will struggle to understand character motivations, political dynamics, and the significance of key plot events.

Aelin Galathynius is the nineteen-year-old protagonist and rightful queen of Terrasen who fights to reclaim her throne from tyrannical forces. Also known by her assassin identity Celaena Sardothien, Aelin is characterized as kind, intelligent, and fiercely loyal, possessing powerful fire magic. In Empire of Storms, she struggles with her identity, past trauma, and duty to her kingdom while gathering allies to fight Lord Erawan and the Valg. Throughout the novel, Sarah J. Maas explores Aelin's realization that her destiny was orchestrated by forces working behind the scenes long before her birth.

At the climactic ending of Empire of Storms, Queen Maeve captures Aelin after a brutal battle. Maeve reveals she manipulated events for centuries, foreseeing that Aelin would lead her to the Wyrdkeys, and deliberately bound Rowan—Aelin's true mate—to her through a blood oath. When Maeve threatens to torture Elide unless Aelin surrenders, Aelin sacrifices herself but secretly passes the two Wyrdstones to Manon Blackbeak. A sadistic warrior beats Aelin savagely before Maeve takes her captive, leaving Aelin's fate uncertain and setting up the next book's rescue mission.

Aelin Galathynius and Rowan Whitethorn's relationship evolves from close friendship to romance in Empire of Storms. Rowan is a Fae warrior who serves as one of Aelin's most loyal allies and strongest supporters in her quest to reclaim Terrasen's throne. The novel reveals that Rowan is Aelin's true mate, a profound magical bond in Sarah J. Maas's world. Their romantic relationship deepens throughout the story, though it faces political resistance from Terrasen's lords who distrust Rowan. This connection makes Aelin's capture by Maeve particularly devastating since Maeve bound Rowan through blood oath.

The primary antagonists in Empire of Storms are Lord Erawan of the Valg and Queen Maeve of the Fae. Erawan, a demon-like being inhabiting Duke Perrington's body, declares war on the continent of Erilea and breeds monsters to destroy the world. Queen Maeve serves as the other major threat, revealed to have manipulated events for centuries to obtain the Wyrdkeys through Aelin. Both villains represent different forms of tyranny—Erawan through destructive conquest and Maeve through calculated manipulation. Their combined threats force Aelin to fight on multiple fronts while gathering allies across Erilea.

Manon Blackbeak is a witch from the Ironteeth clan who undergoes a significant moral transformation in Empire of Storms. Initially serving the King of Adarlan, Manon begins questioning her allegiance to cruel leadership and eventually defects from her clan to become Aelin's ally. She saves Dorian Havilliard from rival Yellowlegs witches, demonstrating her shifting loyalties. At the novel's climax, Manon receives the Wyrdstones from Aelin and chooses not to intervene in Aelin's capture, understanding the importance of keeping the magical keys away from Queen Maeve. Her character arc explores themes of conscience and redemption.

The Wyrdkeys (also called Wyrdstones) are powerful magical artifacts central to the plot of Empire of Storms. These ancient keys possess immense power and are sought by both Lord Erawan and Queen Maeve to control fate and unleash destruction across Erilea. Aelin discovers she must find a lock to use with the Wyrdkeys to send Erawan back and stop his conquest. However, forging this new lock would require Aelin's entire lifeforce as a sacrifice. At the story's conclusion, Aelin secretly transfers the Wyrdstones to Manon Blackbeak before her capture, ensuring they remain out of Maeve's hands.

Empire of Storms explores themes of sacrifice, loyalty, and destiny as Aelin Galathynius confronts impossible choices to save her kingdom. The novel examines leadership challenges as Aelin faces political resistance from Terrasen's lords who question her authority based on age and relationships. Sarah J. Maas develops the theme of manipulation versus free will, revealing that powerful forces orchestrated events in Aelin's life long before her birth. Additional themes include the cost of power, the complexity of moral choices during war, and the strength found in chosen family and alliances as diverse characters unite against common threats.

Empire of Storms concludes with a devastating cliffhanger as Queen Maeve captures Aelin after a brutal confrontation. During the final battle, Maeve reveals her centuries-long manipulation to obtain the Wyrdkeys and holds Elide hostage to force Aelin's surrender. Before being taken, Aelin secretly passes the two Wyrdstones to Manon Blackbeak, ensuring they remain hidden from Maeve. Aelin endures savage beating by one of Maeve's warriors and is dragged away captive, while her companions—including Rowan, Dorian, Manon, and others—commit to mounting a rescue mission, setting up the dramatic events of the next book in the Throne of Glass series.
