Eternal Eclipse™ World
Eternal Eclipse™ World is a Fabric world generation mod from Sunnie Corporation that adds new biomes and dimensions to existing worlds, with regions such as the Chromatic Frontier and the Lost World.
What it does
The mod brings a large set of new terrain to the Eternal Eclipse universe, the series created by SunniePaws. Players explore biomes named the Chroma Forest, the Ashen Wasteland and the Deeper Sea, along with an Atlantic Sea area, and reach a dimension called the Lost World. Each region is generated in the world, so new areas appear while exploring rather than through crafted items.
The Underworld and Crimson Highland regions add volcanic and crystal terrain, including a Crystal Spike biome and a Volcanic Wonderland. Installation covers the server and each player's game. It is published for Fabric only, for game versions 1.21.8, 26.1.2 and 26.2, under the MIT License, and it is not open source.
