Ona Shai, belonging to the Yuuzhan Vong, held the position of Prefect for the Baanu Miir.
Born into Domain Shai, Ona had a minor curvature of her spine. Usually, Yuuzhan Vong with physical deformities were killed upon birth, but Shai was spared because her condition didn't hinder her capabilities. The issues plaguing Baanu Miir made her extremely angry that they were being ignored. Furthermore, Ona Shai was younger in age compared to Nen Yim.
