Bygone Nether

by izofar

Bygone Nether adds new structures to each Nether biome along with new mobs that spawn in them, and it works on both Fabric and Forge.

FabricForgeClient and serverMIT LicenseOpen source1.16.5 – 1.20.1

What it does

Each Nether biome gets its own structures, and the mod also brings in mobs that live inside those areas. The fortresses are redesigned, and bastion structures are added to the Basalt Deltas. Installing the mod needs no other mod dependencies.

Key features

  1. Biome-specific structures

    Each Nether biome has structures that are unique to it, so exploring different biomes shows different ruins and builds.

  2. New Nether mobs

    New creatures inhabit the added structures and the biomes they belong to.

  3. Redesigned fortresses

    The vanilla Nether fortresses are reworked, and bastion structures generate in the Basalt Deltas.
