Lung Tien Xian
|Name:||Lung Tien(?) Xian|
|Date of Birth:||Unknown|
|Special Abilities:||Divine Wind(?)|
In Throne of Jade, Lung Tien Qian said that she and Lung Tien Chu were "hatched of Xian". Her exact quote, addressed to Temeraire, is "(Lien) is your older cousin. She was sired by Chu, who was hatched of Xian, as was I." In other words, Qian and Chu are siblings or or at least half-siblings with Xian as their shared parent.
Lung Tien Xian may have been the true name of the ancient Celestial dragon otherwise referred to as "Grandfather", since that was the only name omitted when Qian listed all of the living Celestials. ("There are only myself and Lien now, who are female, and besides Grandfather and Chu, there are only Chuan and Ming and Zhi, and we are all cousins at most.")
Alternately, Xian may have been a female Celestial dragon sired by "Grandfather", but her subsequent disappearance would be difficult to explain. According to Qian's list, she herself and Lung Tien Lien were the only two female Celestials left. Since Celestials did not fight in China, they would presumably live out their natural lifespans into old age, and there is no obvious reason why "Grandfather" would outlive his own daughter.
Yet a third possibility is that Xian was an Imperial dragon (perhaps a female who mated with Grandfather) and thus omitted from the list of Celestials. In the same conversation, Qian mentions that Celestials cannot interbreed among themselves and always have at least one Imperial parent. In this case, the correct name would be Lung Qin Xian.
The family trees in the "Grandfather" article present several possible genealogies, depending on how "Xian" is identified.
