Her hair glinted ebony, masses of it that poured down across her shoulders, past her lap, to coil around her feet. When she stood, it would trail on the floor like a banner. Her enormous eyes were an ice blue of such arctic purity as to make Lady Gelle's eyes look like mud-puddles. Skin . . . Miles felt he had never seen skin before, just blotched bags people wore around themselves to keep from leaking. This perfect ivory surface . . . his hands ached with the desire to touch it, just once, and die. Her lips were warm, as if roses pulsed with blood. . . . How old was she? Twenty? Forty?

Rian Degtiar (RAI-ahn DEHG-tee-ahr), a member of the Cetagandan Empire's haut class, served for a time as the acting keeper of the Star Crèche after the death of the Empress, Lisbet Degtiar, with the title of "Servant of the Celestial Lady, Handmaiden of the Star Crèche". As a fellow member of the Degtiar Constellation, she was related to Lisbet, though three generations removed.

- ―Miles' later sense of Rian[src]
At the conclusion of the novel she was elevated to permanent keeper of the Star Crèche and became the leading one of Fletchir Giaja's Empresses, the one who was tasked with the job of creating the next haut-Emperor.
