had a similar idea for a bit of my setting so I will list it here for possible inspiration.
the sky kings
riders, traders, rulers of the vast sky-ship fleets the sky kings or zes-hel as they call themselves (which is conveniently translates as sky kings) are the present most rich group of individuals in the world, sailors of the sky in the ships they build or inherited from Haga Vato-yusha and are the single most reliable trade network in the world however some are far more close to there older roots as raiders willing to strip settlement down to the foundations.
The sky kings also rule the dockland as they call them or the tamed floating earth bergs once ruled by the Haga Vato-yusha which are neutral territory and violence is forbidden there as this is where houses intermix, swap crew and new ships are built.
They are noted that in addition to the normal pantheon the sky kings have added in the saint of artifice, a sun god and several wind gods to their pantheon. They like arcane magic much more than most folk
their rulers are called hels but outsiders are far more likely to call them Zhels as that caught on somehow.
the types of ship
moriha the smallest ships they fly, good for getting in and out of small places fast carries a crew of thirty plus cargo and fuel.
jegehaso the medium-sized ship of the fleets the most used and the general workhorse of the fleets crew of 100 plus cargo and fuel.
shuchiha and largest type normally only seen in war or diplomacy the zhel rules from one of these with one per house. A crew of 750 plus cargo, fuel and war machines.
