Hi, could you please add the Dead Man's Abyss mod?
https://www.curseforge.com/minecraft/mc-mods/dead-mans-abyss
Description: This mod adds a horror event that randomly triggers after the player has been to the nether (or by dropping a blind quartz in the water)
Once the event is triggered, it will become night and 2 entities will spawn : The Sreecher, and the blind. They rely on sound to track the player. The more the player makes sound, the more their radius extend.
Thanks for reading !
