Humans are fairly resourceful, and can live practically anywhere. They've created massive ships from the heavily wooded islands that are located along the suns usual path. They occasionally create massive floating cities, maintained with trade with their selkie allies.
Elves are the dolphin riders. They typically make their homes on the well lit islands, and have an alliance with the dolphins. They frequently trade with the Humans and the halflings.
Halfllings Savage humanoids scattered throughout the islands, they worship mad half-gods from outside the pantheon. Instead of saying that the sun is tied by a massive invisible rope to a giant turtle, they make a claim that it is a man, Pay-lore who demands that they smite beings that live after death. That sort of madness. Cannibalism is also a tradition, being either active or passive depending on the tribe.
Dwarves live on the Continent to the north. A place where the sun rarely touches, they've adapted, eating only the giant mushrooms that grow there and the feral beasts. They are fanatically devoted to Gorozoth, the Fire Boar. Their ultimate goal is to sink the ocean beneath waves of magma. They have created great metal ships that can sink beneath the waves, and biomechanical monsters willing to devour whole floating cities if they have the fortune of running into one.
Vasharans are the twisted mockeries of humanity that serve Hanuman. Some are his creations, others are humans that have followed his teachings and were changed.
