Terralith is a Minecraft 1.18 datapack by Stardust Labs that overhauls Overworld generation. With 85 new biomes, including volcanoes, valleys, skylands, 11 cave biomes, and terrain returning from older versions of Minecraft, Terralith changes the mood of the whole Overworld.

Amazingly, Terralith is just a datapack, meaning it's fully compatible with vanilla 1.18. It's also available as a Fabric mod.

Feel free to share the best seeds you find with Terralith in the comments.
