Ona
Biography
Guide through Sky City
Ona receives Saul as the female official responsible for Sky City's internal affairs, guides him by flying carriage through Flower Sea Street, and escorts him into the White Glass Castle. Her poised service initially resembles an independent steward's role. During Saul's confrontation with Ophelia, however, Ophelia speaks of having Ona accompany them while voices emerge from different parts of her own body. The exchange reveals that Ona is among Ophelia's separately embodied consciousness divisions and is, by then, contained within the larger composite existence. (Chapters 756–757, 791–792)
