Aetherial Islands is a worldgen datapack for Java that generates a floating islands world, and it also ships as a mod for Fabric, Forge, NeoForge and Quilt. It rethinks 3D noise so the islands are not large fragmented slabs of land. It must be present on the host of a world, and it is optional for players who only join.
Loaders and versions
- Fabric, Forge, NeoForge and Quilt: Minecraft 1.19 to 1.21.11. The newest build needs no dependencies, optionally Lithostitched and No Void Structures.
What the terrain looks like
Typical floating island generation has no hills, rivers or oceans. This pack adds all three, plus flat plains, caves and structures sitting on rolling hills. Mountains rise from the islands, rivers cut across them, and the ocean bowls float in the sky.
Every vanilla structure and biome still generates in this world type.
How to install Aetherial Islands
- 1.Mod route. Install your loader (see how to install Fabric or Forge and NeoForge), then place the mod file in the mods folder and launch with that loader's profile.
- 2.Datapack route. The project also ships as a plain datapack release, so players without a loader are covered.
Compatibility and trade-offs
Any other mod that rewrites terrain will likely overwrite this one, or be overwritten by it. Mods that only add biomes should work. If bodies of water fail to generate, the optional Lithostitched fixes it, a workaround needed because of the technique the pack relies on and how surface builders behave.
The creator also lists add-ons that extend the idea, including a Nether version called Diabolical Islands, Angel Islands for deep ocean biomes, Skylands over the Sea with an infinite ocean below, and a Clusters add-on that leaves large gaps between island groups.

Questions about Aetherial Islands.
3 questions
Is Aetherial Islands a datapack or a mod?
Both. The plain datapack covers 1.19 to 1.21.11 and needs no loader. The same content is also packaged as a mod for Fabric, Forge, NeoForge and Quilt, so you can pick whichever route suits how you already play.
Does Aetherial Islands work with other terrain mods?
Usually not together. If another mod changes the terrain, one of them will probably overwrite the other. Mods that only add biomes should be compatible, and Lithostitched is the optional fix if water fails to generate.
How do I stop structures generating in the void?
Install the optional No Void Structures mod. It stops structures from generating broken and cut off in the void, which can otherwise happen with some structures in this world type.
