⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary (Complete and Chronological)

After nearly ten days of relentless rain, the storm finally breaks on the ship carrying Arwen and the other refugees. Arwen steps onto the deck, letting the unexpected sunlight wash over her. The warmth reminds her of her home in Onyx—cut grass, white butterflies, and cicadas chirping—but also of the lives she took in a rage after her mother’s death. The gruesome memories of blood and bone make her feel seasick.

Other passengers trickle onto the deck. Mari approaches with Ryder in tow, and Griffin summons Mari to assist King Eryx. A tense exchange occurs between Griffin and Ryder over Mari’s nickname; Griffin’s murderous glare suggests unspoken feelings. Arwen notes that Griffin is fidgeting with his armor, an unusual display of nerves.

The crowd gathers around King Eryx, who announces they have arrived at their destination: the kingdom of Citrine. Yet no land is visible in any direction. Arwen spots Kane showing his sword pommel to her young ward Leigh, sparking a mix of jealousy and reluctant appreciation. She tries to warn Barney about Kane’s influence, but her comment embarrasses Leigh, who slips away.

Kane pulls Arwen aside, having been sobered by a potion from Mari. He whispers that he spends time with Leigh because she is lonely. Arwen bristles but cannot deny his care. Finally, King Eryx reveals the truth: Citrine is not on the surface but on the ocean floor, invisible to the naked eye.

Griffin: Uncharacteristically fidgety, he seems agitated by Ryder’s flirtation with Mari. His demand to call Mari by name suggests respect, and his murderous glare hints at deeper jealousy.
Mari: Remains aloof toward Ryder’s advances; her lack of blushing and academic interests reflect her guarded nature.
King Eryx: Boastful and dramatic, he tries to inspire confidence in the refugees, but his false humility and potbelly undermine his majesty.
Leigh: A ten-year-old girl who finds interest in Kane’s sword; she is easily embarrassed and lonely.
