About this Mod

Features
Along with the world generation, this mod contains a few key features that I think make the experience more fun and balanced:
Mod Features
Aeroscapes World Generation
The floating islands, with all vanilla biomes and structures (except oceans and the structures that spawn there).
Three new biomes: Void Shores, Voidsea, and Deep Voidsea. These dangerous, barren biomes replace the world's oceans, and Trial Chambers and Strongholds generate there.
Rebalanced ore distribution to work perfectly with the worldgen & emphasize exploration, with ore spawn rates depending heavily on biome. Check the wiki for more info!
Aerolite
A special stone type that generates everywhere and can be mined for aerolite twigs.
Aerolite Twigs
You can mine these floating items from aerolite veins and eat them for a brief burst of levitation. Keep some on you for emergencies!
Gilded Aerolite
In hot biomes, some aerolite will spawn with golden flecks and drop gold aerolite twigs.
Aerolite Charm
Crafted with quartz, an ender pearl, and aerolite twigs, this special tool lets you teleport straight upward through solid blocks.
Quickslate
A decorative block, crafted with aerolite twigs, which helps you run faster and jump higher.
Can be polished and chiseled into stairs, walls, and slabs.
Music Discs
Two new original music discs, yaw and view, composed by Elephants.
Requirements
Requires Lithostitched.
Requires Sinytra Connector on NeoForge.

It has tons of awesome content and polish, as well around 150 modded biomes, new crops, structures, immersion features, and more.


FAQ
❓Does this mod support Terralith, Nature's Spirit, BYG, or other biome mods?
Generally, yes! Though they should work out of the box, they will not have the special features I developed for this pack. To add them, check out the internal datapack's "preset" biome tags. If you add a custom data pack which adds the new biomes to those tags, they should get the right features automatically. If that sounds like a lot of effort, try the official modpack!
❓Can I use this in my modpack?
Definitely!
❓How do I report issues?
Use the issue tracker on GitHub, linked in the sidebar.
❓Other mods' structures are spawning in the void when I use this pack :(
You can work around this using Lithostitched and a custom data pack. Check out this part of the internal data pack for an example.
❓I keep getting bad spawns!
Try Serilum's Village Spawn Point mod, linked in the recommended mod section below.
