The Afterdark
The Afterdark adds a 384-block-tall dark dimension of hidden resources, reached through a portal and tied to the Deep Dark.
What it does
The dimension is a hardcore world with its own biomes, and some resources appear only inside those biomes or in its dungeons. Dense world generation makes travel slower and more involved, which the author intends to reward rather than leave dull. Because the biomes sit in their own dimension, the Overworld, the Nether and other dimensions stay unchanged.
Client and server: both the server and every player need the mod. It is published for Fabric, Forge, NeoForge and Quilt across nine release versions, 1.20 – 1.21.5, and is open source under the GNU Lesser General Public License v3.0 or later. The author says it may be used in any modpack as long as that license is followed.
