67 Entity [Horror]

The mod is a psychological horror addition built on the familiar world. The entity progresses through a multi-day escalation cycle: in the first day it stays out of sight and the world is quiet, so a player can gather resources and set up a base without interruption. From days two to three it leaves subtle signs such as wooden signs placed behind the player, unexplained door creaks, faint whispers in chat, fleeting shadows and fog. From day four onward it shows itself openly, through close-range stalking, brief flashes, sightings on the horizon and relentless chases that can turn into direct combat.

When the entity chooses to fight, it engages in melee instead of vanishing. It has 100 HP and takes damage from swords, axes and ranged weapons, and it deals half a heart of damage per strike, which keeps the melee spacing dynamic. Defeating it triggers a short visual aftermath with temporary sensory distortion. The mod is a Fabric mod for client and server, so the server and every player need it. Builds cover 1.20.1 – 1.21.1 across eight release versions, and the code is released under the MIT License, but the project is not open source.
