山村貞子 | Yamamura Sadako

The mod adds the Yamamura Sadako curse, a horror entity whose aim is to frighten the player in several ways, starting with a simple stalking routine and building toward a closing sequence of full cutscenes. Her figure is that of a pale woman with her features concealed by long black hair, dressed in a stained white gown with a ragged hem. The curse moves through different stages as the player advances, and most of its animations were coded for the release.

Installation requires only the mod itself on either Forge or NeoForge, and it runs on the client and server together, so both the server and every player need it. Files are published for 1.19.2, 1.20.1 and 1.21.1, with the latest Forge and NeoForge builds at 0.2.0 for 1.20.1 and 1.21.1 respectively, both in the beta channel. The config file lets server owners change the spawn rate of the curse.

The mod is in beta and is not open source; it is released under All rights reserved. Its author notes that it is buggy, especially on 1.20.1 and 1.21.1, and that a beta stage receives updates less often until release, with ports to other versions and mod loaders planned.
