Djorii'surle'maj's great-grandfather

A male  was the great-grandfather of the Novice Djorii'surle'maj. The Duinuogwuin's exact age was unknown, although Rin Sakaros thought of him as "ancient" and he was old enough to have had two generations of his long-lived descendants between himself and the baby Djorii in 159 ABY.

The "Star Dragon" first encountered Rin in 87 ABY, after she and her fleet had just navigated the nearly-impassable hyperspace barrier west of the. At Rin's telepathic invitation, the Duinuogwuin consented to perch on the bridge of the Sith Star and speak to Rin for many hours. He was familiar with the geography of what became the Romasi sector, as he was able to direct Rin there. Rin did not share the nature of their conversation with her brother Tariun or her apprentice Keltrayu, but described herself as "humbled" afterward.

Seventy-one years later, Rin and the Star Dragon met again. Now Queen of the Golden Empire, Rin was summoned to the bridge of the Sith Star; the Star Dragon was flying in a holding pattern, having deliberately sought her out. This time he spoke telepathically with Rin, Sorrik, and Jinyx Windrunner, warning them of a coming danger which would consume the Duinuogwuin and offering Djorii to Rin's service. Though he had not been reported by any of the Empire's worlds, he had clearly kept tabs on Rin, as he was able to speak of Centurions by name. Rin took Djorii under her protection and offered the same to his great-grandsire, but the elder Star Dragon refused, believing his destiny was in the conflict and he had to meet it.

Following their meeting, Rin never saw the Duinuogwuin again. Alone among the beings of the Empire, she knew his real name (and he her full name, "Katherine Sakaros"), but she never divulged it.
