When you install this mod, "player from another server" will begin to appear in your world, which will be hostile to you. I advise you to run away from him, because it is extremely difficult to kill him.
If you hear strange whispers or sighs, just run! Although, if you want to, you can listen to his whispers and make out a secret message there
Reverse its speech and then you'll hear:
"Don't be afraid..."
