Here are some of the notes for my EarthSkye setting. Sorry if it's a
little messy; I'm still working on it.

EarthSkye is a world where islands float above an endless ocean.
People travel between islands in airships made from a wood that
naturally floats in the air. Almost everyone has a tie to one of the
four elements; those without such a tie are considered cursed.

Geography:

Ocean:
-Stretches from horizon to horizon.
-Islands float above it.
-Only permanent surface feature is the Axis Mundi.
-Many fish, no ocean mammals.
-Seaweed mats, free-floating coral provide anchoring for some sea creatures.
-Raft cities on the surface mostly inhabited by water-aspected.

Islands:
-Float over the ocean.
-Kept up by naturally occurring ore in the rock.
-Rise suddenly from the ocean w/o warning, and find their permanent
height within hours.
-Eventually sink beneath the ocean, to a depth beyond reach.
-Climate varies from tropical to temperate.

Axis Mundi:
-Only permanent surface feature of ocean.
-Lies in the rough center of the world.
-White tower covered in undeciphered runes that glows brightly as the full moon.
-Stretches as high and as deep as anyone has ever been able to go.

People:
-Almost everyone is born connected to one of the elements, and has
powers relating to that element.
-Air: Float/fly in the air, wind gusts, weather prediction, etc.
-Earth: Toughen themselves, sculpt natural earth/stone, find ores, etc.
-Fire: Create/control fire, fire blasts, etc.
-Water: Breathe water, swim easily in water, water blasts, weather
prediction as well.
-Unaspected/Casteless: Considered cursed and touched by the Dragon
Below. Often killed at birth.
-Most people wear loose cotton clothing.

Religion:
-Worship the spirits of the world, with the Great Dragons of the four
elements seen as the most powerful spirits.
-At death, your soul is taken to the afterlife by the Dragon of your
birth element.
-Fifth Great Dragon, the Shadow Dragon or Dragon Below, is seen as the
god of destruction.

Airships:
-Primary means of transport between islands.
-Made from mostly from liftwood.
-Rigged above and below the main hull.

Liftwood:
-Naturally floats in the air.
-Grows on many islands.
-Comes in different varieties.
-Can have its properties altered through alchemy/sorcery.

Magic:
-Primary elementalism & alchemy.
-Easiest for someone to manipulate their aspect element; hardest to
use their opposite.
-Unaspected can learn elementalism, and have an equally hard time with
all elements.
