"And yes, the word is also used in SW for people from Naboo." No, that would be Nabooian. Nubian is for people of the planet Nubia. The royal starships of Naboo are of Nubian design. The workings of them. The Naboo added chrome to desinate royality and accually made the ships work better than normal and such. They didn't build their own ships. No shipyard... no industry besides plasma containment and use. Thus, no way to make ships. So they buy from Nubia. Thus, the ships have "Nubian hyperdrive(s)."
