It will create 15 random names for floating islands, but the names will function for floating cities and other large places in the sky, provided that you substitute the isle and similar synonyms in the name of course. First sort, the first six names in this generator are names that are mostly designed to capture a very aerial feel, although they are still an entirely unique name. Some elements here are different, which can make certain names sound different from others. Some might sound darker and more sinister, while others might sound light and angelic. Our goal was to provide rules for naming that produce a variety of sensations, but that all share aerial elements. Since this is somewhat arbitrary, we suppose. We tried to incorporate styles from other cultures as English sounding names often didn't suit in all environments. There are also several Norse elements, some Asian elements and many more. The last 4 names are mostly word-based names and names derived from sky-related words. Names such as 'Aurora Isle,' 'Nimbus Island,' etc. These names are typically better than the first six names, so I hope they will help you if you need them.
