Shadow of the Soul
by Ixra
Shadow of the Soul is a NeoForge horror mod for 1.21.1 that tracks a player's fear level and reacts with darkness, whispers and a stalking entity.
What it does
A Fear Level system from 0 to 100 rises with darkness, deep underground depths and injuries. Standing in bright light is the only reliable way to lower it again. When fear runs high, a malevolent entity appears behind the player, studies the shadows and vanishes the moment the player tries to confront it. Operators can set the fear value directly, and a toggle controls the visual fear indicator.
The horror is meant to be psychological rather than a typical monster mod. Localized whispers and phantom cave noises speed up the heartbeat as sanity slips, and high terror levels prevent sleep, so a player must stay awake and survive the night by hand. Shadows grow aggressive at high fear and put out nearby torches and light sources, which turns darkness into the main threat. The mod runs on NeoForge, and the server and every player need it, since the environment is client and server.
The mod is published for NeoForge 1.21.1 only, with a single build, 1.0, released on 2026-01-18. The code is licensed under All rights reserved, so the mod is not open source.

Shadow of the Soul is not a typical monster mod. It is a system-driven horror experience that tracks the player's mental state through a complex Fear Level mechanic. The environment reacts to your terror, making the darkness your greatest enemy. Commands: /fear set [0-100] - Sets your current fear level (OP only)…
