What Is This Dimension
by Heurazy
Forge worlds on 1.20.1 gain an otherworldly dimension that feels eerie, with disturbing details throughout, under the name What Is This Dimension.
What it does
The dimension is added to the game as a separate world space that players can enter and explore. Its look and feel are built around an eerie, uneasy mood rather than a standard biome set, so the setting itself is the main point of the mod. Installation covers the server and each player's game. Files are published for Forge only, for 1.20.1, and the license is All rights reserved, so the mod is not open source.

Creepy atmosphere

Unsettling elements
Odd details in the dimension are meant to make exploration feel uncomfortable on purpose.
