Worlds Apart: Alternate Overworlds

Worlds Apart adds a number of new world types to choose from. Originally this was meant just to be sky islands but I went a little overboard with it. They present different challenges that can include how to get resources or food. It attempts to include ores and biomes from other mods.

World Types
- Sky Islands — A void world filled with configurable floating islands. Each island uses a single biome and can contain caves, scaled ore layers, lakes, structures, ocean bowls, and special oversized islands for Strongholds and Ancient Cities.
- Extreme — An amplified Overworld with biomes four times wider than Large Biomes. Adds floating islands, volcanoes, twisted stone tentacles, enormous plateaus, meteor craters, and massive ravines while retaining normal biomes, caves, structures, ores, and decorations.
- Endless Ocean — An entirely aquatic Overworld containing only ocean biomes, including compatible modded biomes. Water reaches the upper build limit, and players begin on the seabed inside a drained glass bubble.
- Underground — Normal Overworld terrain enclosed beneath a separately generated stone ceiling. Bedrock seals the top and bottom of the dimension while regular biomes, caves, features, ores, and structures continue to generate inside.
- Understone — A world completely filled with stone and deepslate, containing enormous underground caverns with biome-appropriate surface terrain, vegetation, and trees. Normal caves, aquifers, ores, geodes, and underground structures remain available.
- Dusk — A normal Overworld trapped in perpetual dimness. Natural daylight reaches only light level 6 and falls to 0 at night, allowing exposed undead to survive during the day while leaving block lighting unchanged.
- Cube — A finite 128 × 128 × 128 section of normal Overworld terrain surrounded by void. It includes caves, oceans, ores, features, and structures that fit completely inside the cube, with no bedrock covering its exposed lower face.
