What it does

The mod expands the deep biome with new biomes, including the deeplands, the echoing forest, the overcast columns and the blooming caverns. A hidden structure, an ancient temple described as the home of the warden, can be found in the new terrain. Breaking the ancient vases in that temple can awaken an ancient lurker, so players are advised to break them carefully.

Over a hundred new blocks are added for building, including a stone variant of the sculk family and a wood type that is new to the mod. The item set includes a warden armor set and matching tools, an upgrade to the elytra and a sculk transmitter. Eight new mobs are included, one of them a miniboss. To enter the Otherside, a player kills the warden and uses its heart.

Deeper and Darker depends on Fabric API and oωo (owo-lib), both of which must be installed. Installs cover client and server, so the server and every player need the mod. Published builds span Fabric, Forge, NeoForge and Quilt across 9 release versions for 1.19.1 – 1.21.1. The source is open source under the GNU Affero General Public License v3.0 only, and its source code and issue tracker are public.
