Terralith Legacy

Terralith Legacy is a datapack made to completely revolutionize the Overworld's generation. This pack is the culmination of nearly a year of work and more than 500 hours of effort and research. Terralith adds over 50 brand-new biomes, as well as updating almost every vanilla biome with new and improved features. It also includes the most advanced biome layout ever created for a WorldDen datapack, 1.18's extended world height and a recreation of the new caves as well as new cave types.

This is the latest version of Terralith available for 1.17, it is now unsupported and will not be updated.
