GrimVeil
by Aberrants
GrimVeil is a Fabric mobs and world-generation mod that adds a dark, eerie expansion with a biome, new creatures and a toolset.
What it does
The mod introduces the Lost Woods, a dark exploration biome built around atmosphere and discovery. Its creatures are meant to be fought or avoided, and the setting is left open for players to interpret. The expansion adds more than fifty blocks and a toolset whose material sits after netherite in progression.
Installation needs Fabric Loader and Fabric API, plus TerraBlender 4.3.0.2, which places the biome into the world. GrimVeil runs on client and server, so the server and every player need it. Its only file is an alpha build for 1.21.4, published on 2026-01-19. The mod is under All rights reserved and is not open source.

Creature encounters
