G'trial was a dragonrider and Weyr healer late in the Second Interval and early in the Third Pass.
After J'trel saw the splint Lorana had made for her brown fire lizard Grenn, he said, "Our Weyr healer (G'trial) could take lessons from you."
After G'trial had watched over thirty other dragons succumb, he lost his own dragon. Later, J'lantir learned that G'trial had overdosed on fellis juice laced with wine and something else that could not be identified. Dalia told J'lantir that she would look after Gatrial.
