Prologue: Kingfisher
Kingfisher executes a vampire in the Black Palace.

Chapter 1: Saeris
Preparing for her coronation, Saeris is surrounded by tension.
Taladaius insists she must claim the throne immediately to prevent a power vacuum.
Kingfisher gives her a hidden silver dagger, and they proceed to the Hall of Tears where she boldly declares herself queen to the four Lords of Midnight.
Chapter 2: Saeris
The lords, especially the witch Algat, challenge Saeris’s right to rule.
To prove her vampire nature, she must drink blood and chooses Kingfisher’s wrist.

Kingfisher kills him instantly, triggering a chaotic battle.
Saeris unleashes her power to command the entire court to its knees, issuing new edicts before Kingfisher leaves to check on his sister.

The camp suffers devastating losses fighting just eight of these creatures, and Khydan witnesses a black rot spreading from their bodies.
Chapter 5: Saeris
Khydan returns with feeder heads for study.

A casual question from a fire sprite about wedding plans leads to a tense moment when Khydan bluntly shuts down the idea.

Their intimate night reveals her new hybrid strength and deepens their bond through shared blood and power.

Khydan and Renfis discover the Irrín war camp has been utterly destroyed, leaving only a scorched crater and ash.
The feeders left tied to a tree have fused with it, which now bleeds black blood, signaling the rot’s catastrophic spread.
Chapter 9: Saeris
Visiting the unconscious Everlayne, Saeris is guided by the quicksilver to touch the girl’s earring.

Saeris relays Edina’s message.

How the Chapters Fit Together
Brimstone masterfully interweaves two primary plotlines that converge into a single, realm-saving mission.
Saeris’s Arc in Yvelia: The first half focuses on Saeris claiming and securing her political power in the treacherous Blood Court, a journey punctuated by assassination attempts and alliances.
Concurrently, she must confront the awakening—and danger—of her own Alchemist abilities, guided by Edina’s ghost and the rediscovered Foley.
This arc culminates in the shocking cleansing of the Blood Court at the Evenlight Ball.
Khydan & Carrion’s Mission in Zilvaren: The parallel narrative follows Khydan and Carrion’s desperate quest in the human realm.
This is a story of resource acquisition, rescue, and confronting personal history, marked by battles with demons and Madra’s forces.
Their return triggers the next phase of the crisis.
The Converging Crisis: After the evacuation to Inishtar, the separate threats—the rot, Madra’s feeders, and Belikon’s scheming—merge.
The final act becomes a race against annihilation, leading to Khydan’s capture, the revelation of his true name, and the ultimate journey to the dragon realm to seek the one substance that might cure the rot: brimstone.
