In the desert city-state of Gujaareh, peace is the only law. Along its ancient stone streets, there is no crime or violence. Priests of the dream-goddess, known as Gatherers, maintain order: harvesting the dreams of the citizens, healing the injured, and guiding the dreamers into the afterlife...
The Dreamblood Duology is a series of two Fantasy novels by N. K. Jemisin (Known for her Inheritance Trilogy), set in a kingdom inspired by Ancient Egypt where dream magic and its priests are central. The first novel is The Killing Moon about Ehiru, a Gatherer, who discovers corruption at the very heart of power. The second novel is The Shadowed Sun, about Hanani, the first female Sharer, and her discovery of what lays outside of the cloistered halls of the Hetawa."The Narcomancer", available online, is a short story set in the same world, centuries before the time of the books.
Celibate Hero: Everyone in the Hetawa is supposed to swear off sex.
Cessation of Existence: This happens to people who are reaped instead of gathered. Also, Hanani does this to Tantufi at the end of The Shadowed Sun because her soul is so damaged that it would never have found rest.
The Corruption: Pretty much once a Gatherer uses their powers to kill rather than to bestow peace, a long downward spiral begins. If they even suspect they are emotionally unbalanced, they may ask to die.
The Fundamentalist: Arguably the whole city of Gujaareh, but certainly the Hetawa. "Hananja's City obeys Hananja's Law" right down to a pissed crowd of peasants screaming that at you when you break it.
In the Blood: Dreaming talent tends to run in families. If it is a particularly strong talent not caught early, it leads to madness. This tends to happen to women, because the Hetawa will not let them work.
Insistent Terminology: The first Prince of Gujareeh was almost named a king, but he declared that because the goddess Hananja was the only queen, while living he would be a prince and only become a king upon death at Hananja's side.
Men Are Generic, Women Are Special: Thoroughly explored for both its positives and its negatives. On the one hand, men in Gujareeh are genuinely invested in the happiness and pleasure of their women. On the other hand, women are denied certain roles in society that they may want to take part in just because women are considered goddesses and ordinary things like working are beneath them.
Nijiri dedicates the whole of the first book to finding a way to save Ehiru from becoming a Reaper.
Nice Job Breaking It, Hero: Ehiru is a very talented Gatherer. Too bad he never questioned which of his assignments were actually just political hits that ultimately made all the disaster of the books possible.
Xanatos Gambit: Eninket creates some pretty wild plans to ensure that he will become an immortal and take over the world. Ehiru refuses to give in and become a Reaper? Oh well. He can just torture Nijiri and get the same effect. Sunandi makes it to Kisua to warn them war is coming? Oh well. He had warriors ready years ago. He's also just going to kill all of them with his inevitable Reaper. The only reason he fails is because he underestimates how much Ehiru's hatred and determination will keep his head clear enough to kill him.
Warrior Monk: Sentinels. Gatherers to a slightly lesser extent.
Weird Moon: The Dreaming Moon. Word of God says it's actually a gas giant and this world is on one of the planet's moons. The Waking Moon is also another of the planet's moons.
Well-Intentioned Extremist: Eninket doesn't actually want to live forever and wage war until the world is united under his rule, he just sees it as the only way peace is actually possible. He could also just be really, really crazy, but the people who knew him best stick with this one.
What the Hell, Hero?: Sunandi constantly asks how Ehiru and Nijiri can effectively live as hitmen. They in turn ask her how she can lie for a living.
