KS Biomes
by nugrevan
KS Biomes adds six new biomes to world generation: Calcite Cliff, Coral Graveyard, Prismarine Forest, Fungal Cavern, Burning Dark and Frozen Dark.
What it does
Calcite Cliff appears as a cliff above the ocean and is built from calcite. Coral Graveyard is a rare variation of warm ocean where a coral reef is dying, and only a handful of coral blocks remain alive.
Fungal Cavern generates underground where humidity is high, with a mycelium floor covered in mushrooms, some of them large enough to emit light. Mycelium blocks there keep ores from generating, so mining the cave is safe. Burning Dark and Frozen Dark are two variations of the deep dark: the first is filled with magma patches and is rare, and the second replaces deepslate with ice. Both add no extra sculk underground beyond what the deep dark already generates.
KS Biomes is a server-required mod, so the server must run it, while players may add it on the client. It is distributed as a data pack as well as a mod for Fabric, Forge, NeoForge and Quilt. Builds cover 1.21.11 – 26.2, with 26.2 as the latest version, and the code is released under the MIT License without being open source. The author notes further biomes are planned.

What the author says
This biome will appear when a cliff is above an ocean, making this amazing looking calcite cliff. This rare biome is a variation of the warm ocean, it will generate a dying coral reef, with only a few blocks of living coral left.
