Here's the question:
What do you believe would be the social and cultural implications in a world that has floating landmasses (floating as in "floating in the air")? These "islands" float much like a boat does in open sea, moving at random (see note) (but with no possibility of flipping over itself).
What I would like your opinion is on each of these islands cultural traditions and political views would be, considering this weird feature...
These islands occur naturally, at both the surface of the planet and these islands are populated by intelligent beings. Also, I believe the randomness in its movements prevent the islands from being used as efficiently for military purposes such as dropping stuff on the surface.
The technology on the surface is steampunk-ish, there are flying airships, cities are huge and large government bodies exist. The people on the Islands try to live in a environment friendly way, since they can't extract resources from the Islands without severely reducing the habitable area they have. However, there are enough resources (food, water) on the Islands to sustain life. In regards to the weather, it varies with an island's geographical position.
Magic does exist in this world and can be wielded by anyone with the appropriate training, but you need to understand the underlying process to be able to use it correctly (that is, to magically heal a wound, you must understand the physiological process of healing).
Both the surface and the islands are populated by intelligent beings, but not exactly of the same race. Trade between civilisations is possible, and occurs rather frequently. There is a common organization to mediate politics between surface and the Islands, but there are sovereign states (Islands are like city-states, and the surface has "regular" kingdoms).
As a side note, this is a fantasy setting, so anything is possible. A source of inspiration for this is the Kingdom of Zeal from Chrono Trigger (see e.g. this fan art).
Note: Just clarifying the random movement point, it was a bad choice of words. The movement would not be random, but it would be subjected to the direction of the winds, similar to a boat on sea.
