T.error
by weirdendTV
T.error is a NeoForge horror mod for Minecraft 1.21.4 that adds sinister entity stalks, eerie messages and world corruption.
What it does
Stalking entities appear in the world and keep returning, while creepy messages arrive at unexpected moments to keep tension high. The mod also interferes with the game world itself, producing faults and sudden damage that the player has to work around, so the line between play and the horror is deliberately unclear. Its author describes the result as a psychological horror playground rather than a conventional scare pack.
The mod is released as a single NeoForge build for 1.21.4, and it is not open source; it is distributed under All rights reserved. Servers that run it need every player to install it too. Versions use a three-number format where the first number marks the build type, the second marks feature updates and the third marks bug fixes. Build 1 is the standard build and the default experience. A wiki is available for players who want more detail.

Something Watches is a NeoForge mod for 1.21.8 with a client and server environment, under All rights reserved and not open source. Something Watches 2.0 is its sequel for the same version and environment, also All rights reserved and not open source.
