Pyrellium

by Lankaster

Pyrellium is a Nether overhaul for Fabric and NeoForge that adds nine new biomes to the Nether while keeping the vanilla layout.

FabricNeoForgeClient and serverCreative Commons Attribution 4.01.20 – 1.21.11

What it does

The mod reworks the Nether with nine added biomes that fit into the existing dimension, so the terrain keeps the familiar feel of vanilla. Explorers, builders and survival players meet new challenges and rewards in the fiery realm, and the content sits alongside vanilla rather than replacing it. Client and server both need the mod, since it runs on both sides. Files are released under Creative Commons Attribution 4.0 for 1.20 – 1.21.11, and a NeoForge build has been available since version 0.4.0.

Key features

  1. Nine new Nether biomes

    Nine biomes are added to the Nether and blend into the existing dimension.

  2. Challenges and rewards

    Deeper areas of the Nether hold new challenges for explorers, builders and survivalists.

  3. Native NeoForge build

    Pyrellium ships a build made for NeoForge, available since version 0.4.0, alongside the Fabric files.
