What it does

Two new biomes are added to the Nether. One is a sunlit forest colored in yellow, which does not burn despite its name and gives the area a golden feel. The other is a dense, mysterious forest with green hues that stands out against the usual red Nether landscapes. Both biomes are generated in the Nether and add variety to exploration there.

The mod adds four new mobs. Netherrack Prowler is a small Silverfish-like creature that spawns often and drops Netherrack. Debris Prowler is an extremely rare Silverfish variant that drops one Ancient Debris on death. Skeletal Chicken is a passive skeletal bird and a steady source of bones in the Nether. Basalt Serpent is a hostile serpent that makes exploration harder. A new precious metal equivalent to diamond is added as an ore, and a new music disc by LaudividniYT completes the content.

The mod is built for Forge 1.20.1, runs on client and server, and requires Geckolib to be installed alongside it. Files are released under All rights reserved and the code is not open source.
