Kaylin: Did you ever learn anything about time in your magical studies?
Nightshade: Yes, I've learned it passes very, very slowly when I'm bored. — Cast in Silence''
Chronicles of Elantra is a fantasy series by Michelle Sagara (also known as Michelle Sagara West, her pen name for The Sun Sword series). The series has nine books, with a tenth book set for release in July 2014. The books follow the life of Kaylin Neya as she deals with the issues surrounding the City of Elantra and the races within it and the strange marks left on her body by the Old Ones.
Brother-Sister Incest: In the Barrani High Lord's line, the power to rule is passed from father to son, and the power to give babies their true names is passed from mother to daughter. Needless to say, the Barrani royal line is extremely inbred.
Half-Human Hybrid: Averted. In a world with five races living in such close contact with each other, it's surprising that there are absolutely no hybrids ever mentioned ever, and Kaylin x Nightshade is the only Interspecies Romance alluded to in the entire series.
I Know Your True Name: Both the Barrani and Dragons have true names. Kaylin knows two: Nightshade's (Calarnenne) and the Lord of the West March's (Lirienne). She also knows Makuron's trues name, but flat out says that she is unable to say it, or even really think it.
Our Dragons Are Different: Elantra's Dragons can shift from human to Dragon form. Other than that, they're pretty much the same. They breathe fire and have hoards.
Passed Over Promotion: Kaylin is still a Private, despite the fact that she saved the fiefs TWICE, spoiler: saved both the former Lord of the High Halls's sons, survived the Barrani Test of Name, saved her Sergeant's sister-in-law, saved the city from a tidal wave, survived TWO encounters with Makuron, exonerated her Sergeant of murder, saved the Lady twice, served as harmonist in recitation of the regalia, saved the Lost Children, and The Green. There are reasons for this. *cough*attitude*cough* When one imortal is explaining her situation, and lack of position to another, he says that Kaylin is in the position she is because she chooses to. From Kaylin's perspective she is a private, a helper of the midwives, and a helper of the Foundling Hospital. From the Imortal perspective, she is the CHOSEN. (spoilers) She is the Erene of Lord Nightshade, the person capable of killing a dragon in dragon form through pure magical power, Lord of the High Court, Kyuthe of Lord Anteela, Kyuthe of the Lord of the West March, Kyuthe of the High Lord, friend and equal to the Lady, backup for the Lady, friend of the Thaalani Castelord, welcome in the Thaalan, friend of the Keeper, Go-between for the Keeper, welcome in the Elemental Garden, priestess of Elemental Water, capable of freeing the dead, capable of carrying True Names, capable of telling stories in the Old Tongue beyond the greatest mages, welcome in the Birthing Caves, Student of Sanabalis, claimed Friend of Sanabalis, Healer, wielder of magic the Dragons find legendary, friend of Lord Tiamaris, friend of Tara, capable of rewriting the words of the Old Ones, Traveller, capable of a feat that killed Old Ones, capable of rewriting True Names, Savior and friend of the only living female dragon, former Harmionist, friend of the Hallione, friend of the Green... The reason she is a private, rather than a princess in the palace is because she REALLY doesn't want to be, because those are part of her life that she chooses to ignore, and because almost no-one is willing to fight her over it.
Though The Emperor placed many restrictions on the Dragons, and those that could not follow them but did not rebel are presumed to be taking a very long nap somewhere. It is possible that the ladies are all taking a snooze. On the other hand, maybe they just don't leave the palace much.
