Lux thought that the Floating Island, Karshvar Draconis, was just a single floating island that was as big as a city.
However, after he and Cethus used several teleportation gates in order to reach the Outer Reaches, he realized that he was greatly mistaken.
Karshvar Draconis wasn't just a single island.
It was a group of floating Islands, and when combined together, they were as large as a Kingdom.
The Floating Island, which was located at the center of the formation, was the Main Island where the Dragon King lived.
The name of the Capital City of the Dragon King was called Rex Lapis, and it was where the majority of the DragonBorns, Elder Dragons, as well as a few Ancient Dragons lived.
The floating islands surrounding it were categorized by the type of Dragon that lived in each of them.
Blue Dragons, Red Dragons, Green Dragons, Earth Dragons, Black Dragons, and the other Dragon Species, which some mortals were unable to see due to how rare they were.
