About this project
What does Apollyon add?
(In Collaboration With M Productions, Creators Of The Man From The Fog)
This project will solely be on 1.20.1 from Act Two and on.

Nobody else is here.
Nobody except yourself.
You've been cursed to wander the depths of this realm alone.
Alone. You're here long enough, and you start to feel another presence with you.
You worry.
Are you really alone, or is there something out there?
Watching?
Waiting?
Stalking...?
Welcome to Apollyon.

- They are not Dwellers.
- They despise that name...
- They are resilient creatures.
- They are infecting your world...
- They do not leave unless they kill or are killed.
- They are behind you...
- They choose only one target.
- They are in your mind...
- They have a chance to haunt you rather than hunt you.
- They are everywhere...
