The Ocean Duchy, situated at the southern end of this world, is a nation comprising the ocean and many islands. Although it's called a country, they are more like a loose federation.
The citizens of the Ocean Duchy are collectively known as sea-dwelling species, aside from the Hapi who live on a few of the islands.
But you can't generalize about the sea-dwelling species, just like in Wansheng Country, where beastmen include both lion beastmen and deer beastmen, there is a huge diversity among different sea-dwelling species.
There are octopus girls with eight tentacles, mermaids who are half human and half fish, and even members of the True Fish Clan that look like salty fish with four short arms.
Even among mermaids, you can't generalize about the different tribes.
For example, Jiao Xi belongs to a type of Parrotfish mermaid, who are special in that they can control the magic power in their bodies and switch between two genders at any time.
