How does The Fifth Season end?

The final chapters reveal that Damaya, Syenite, and Essun are a single woman shown at three different stages of her life, and that Hoa, the stone eater travelling with Essun, is the voice that has been narrating her story. In Castrima, Essun is taken to see a dying Alabaster, his body turning to stone and being eaten by the stone eater Antimony. Alabaster admits he is the man from the prologue who tore the continent open and started the terrible Fifth Season. He asks Essun to help him make it worse, and the novel closes with his question about whether she has ever heard of a moon.

Who broke the world in The Fifth Season?

The unnamed man who stands over Yumenes in the prologue and rips the continent open is Alabaster, the only living ten-ringer and the father of Syenite's child. Using the obelisks and the node maintainers he had freed, he opened a great red rift that will pour ash into the sky for years, beginning the worst Fifth Season ever recorded. He tells Essun that the world's horror justified the act, and that a system so cruel deserved to be destroyed rather than repaired.

How are Damaya, Syenite, and Essun connected in The Fifth Season?

They are one woman at three points in her life. Damaya, the girl the Guardian Schaffa takes to the Fulcrum, chooses Syenite as the name she will bear after her first ring test; years later, after the Guardians destroy everything she loves on Meov, Syenite buries every identity she has held and starts over in the comm of Tirimo as Essun. The rotating present-tense chapters make the three lives feel simultaneous when they are actually sequential. A second reveal lands alongside it — Essun's companion Tonkee is Binof, the Leadership girl Damaya once helped inside the Fulcrum.

Why does Syenite kill her son Corundum in The Fifth Season?

When Guardian ships storm Meov, a Guardian kills Innon by twisting his orogeny inward, and Schaffa reaches for the baby. Rather than let Coru be taken, lobotomized, and wired into a node like the Fulcrum's child maintainers, Syenite presses a hand over his mouth and nose and smothers him, preferring his death to that existence. In her grief and rage she seizes power from an amethyst obelisk, and the resulting cataclysm destroys the ships and kills most attackers along with many fleeing islanders. Alabaster later tells her he understands why she did it — and that he will never forgive her.

Who is Hoa really in The Fifth Season?

Hoa, the strange pale boy who attaches himself to Essun on the road, is a stone eater, and he is also the narrator of the whole novel — the voice addressing Essun as you. He was drawn to Syenite when she first touched an obelisk's power, found her unconscious in the sea after Meov fell, and watched over her for the ten years before introducing himself outside Tirimo. His nature shows early when he turns an attacking kirkhusa to stone, and in Castrima he admits what he is, explaining only that he likes her.

What does the ending of The Fifth Season set up for The Obelisk Gate?

Essun still has not found Nassun, the daughter Jija carried off after beating their son Uche to death. Alabaster's dying request that she help him make the world worse, and his final question about a moon, are left hanging as the book ends. An interlude observes that people of the Stillness never look up anymore and miss what is absent overhead — an early hint that a vanished moon matters enormously. The story continues in The Obelisk Gate and The Stone Sky.
