The World of Corx: Shards of Reality

Corx is a fantasy world devoid of land, where the deadly Ether, an all-consuming substance that dissolves all life, stretches in place of soil. The only habitable zones are the Magic Islands, created by mages of different races and held in place by magical domes that protect against the Ether. The world is divided into three echelons: the upper, where the most ancient and powerful islands float; the middle, the center of civilization and trade; and the lower, immersed in ethereal storms and secrets. There are three races in Corx: Gravians, semi-humanoids with a tail instead of legs who control gravity and live in eternal flight; Crystalloids (Senarchs), intelligent creatures made of living crystals that store and generate magical energy; and Jiri, the material spirits of vanished races who wear Jiro masks that embody their personality and power. Magic is the foundation of the world: without it, the islands collapse, and the Ether absorbs everything. Civilizations forge alliances, trade, fight, and create moving islands, while ancient secrets lie hidden in the depths of the ether. Corx is a world of ephemeral beauty, fragile balance, and magic that exists in defiance of oblivion... P.S. This is my attempt to create an interesting, slightly strange and unusual world. I don't know if it worked, but if you have any ideas for improving, developing or expanding this world, or just any thoughts, you can write about it in the comments:)
