Terralith

About

Terralith is a worldgen overhaul that adds over a hundred new biomes and landscape types using nothing but vanilla worldgen's datapack format. Because it patches no code, it works on Fabric, NeoForge, Forge, Paper, and even vanilla servers — anywhere datapacks load. It also works alongside other worldgen mods like Tectonic or William Wythers. Highlights: shattered savanna canyons, alpine pine spires, lush valleys with custom rivers, deep-dark style caves, and one of the most cohesive vanilla-feeling expansion packs available. The 2.5+ release lines up with 1.21.
