All The Horrors (ATH)

Get ready for:

Cave Dweller

An entity that screams and hunts you down when you go into the caves.

Inside the system (SAFETY)

An false player comes in you world.

Do not kill him!

The Idol

An persistent entity in your server. 

You can speak to him.

Terrifying Freddy

An Freddy-like creature that can hunt you down any moment.

Evil Hunter

Active the ritual and he comes for you.

I'm not going to give any spoilers about it.
