I started tinkering with a setting that is very different from anything I have seen published. At the moment all this is is a list of ideas, some that work well together and some that do not. Consider it the seeds of a potential setting.
The setting is a large cluster of flying islands. All of them share an atmosphere. (That is the only thing set in stone.)
The islands are not tiny spheroids, but more like actual islands found in the ocean. They bob and some spin slowly.
Giant vines tether some together.
Weather is atmospheric, so it moves as waves or fronts from one edge to another, passing over the various islands. That means each island does not have its own weather. Exceptions may exist but they would be difficult to reach by most methods of travel in this setting.
There are one or more suns either orbiting the world or at its center.
There are three layers- outer, middle and core.
The outer layer is where the poor are forced to live. It is vulnerable to astral leviathans, dead sun necromancers, fungal demon spores, telepathic calls from astral entities, the divine brood and/or other monstrous hazards.
The middle layer is where the primary mines are (see below) and where conflicts are mostly between people.
The core is where the dead have sway over the living. Not that is it always a hostile relationship- one's dead ancestors make great allies.
Mining is the primary industry and it is for supernatural minerals (including all the ioun stones in the universe), and alchemical reagents.
Getting around requires giant bird mounts, gliders, and airships for short travel and passage through the Mirror Maze for longer distances.
The Mirror Maze is exactly what it sounds like- an unending maze beyond (behind?) the surface of a mirror. It is populated by reverse monsters and most people survive their trips. Occasionally an entire caravan does vanish, through that is usually not due to the monsters, but the mirror masters, adepts of great power.
There are several forms of FX popular here. Astrology is vital to the survival of the people of the outer layer. Geometry and fung shui is based on the conjunctions that replace ley lines. Mad science competes with magic and the mirror masters are its greatest enemy.
Astral projection brings in the miners, the overseers, the paymasters, the mine owners (dragons possibly), air elementalists that keep the atmosphere from decaying, and/or the secretive seekers who looks for who knows what. This post has been edited by derek_holland on Feb 10 2019, 19:25
