Fifth Season Ch 14 & 15
Syenite and Alabaster are told to wait in Allia. They speculate on the reasons why, and who poisoned Alabaster. Alabaster mentions that no-one's been able known to affect an obelisk in the past three thousand years. Alabaster implies that some node maintainers are orogenes too powerful to be controlled. They are attacked by Edki, a Guardian; he stabs Alabaster with a glass knife and disables Syenite's orogeny. Syenite draws on the obelisk's power, talks to the stone eater inside it, and the chapter ends on a cliffhanger.
Essun and her gang arrive in Castrima, initially bemused by the lack of walls, consistency, and people. In a huge surprise, Hoa is revaled as a stone eater, and seems to have an antipathy to (and shares an agenda with) a stone eater resident in Castrima. There's discussion of how bad this Season will be. There's no word of Nessun and Jija. Ykka uses orogeny to calm Essun. Essun and the gang decide to stay in Castrima, at least for the moment..
How has the relationship between Syenite and Alabater developed?
Why is Syenite able to draw on the obelisk when other orogenes have been unable to?
Orogeny seems to be a multi-facted ability. Is this believable?
Essun is a woman grieving for her children and angry with her husband. Is the portrayal convincing?
