Looking for a Fimfiction Fanfic that I saw a few years ago

Hi, I have been on the search for a fanfic that’s on fimfiction somewhere but for the life of me I can’t find it. It revolves around a mystery/horror plot where you are reading a “cursed book” and the book starts talking to you, and it has hidden messages in each chapter that if you combined led to an image here somewhere on derpi.

Can you describe more about this image? Like what characters are in there? OCs? Twilight Sparkle? Is it semi-grimdark? I would like to know some possible tags it could be.
 
Or maybe a description of the picture? Was it a book? Oh and was this a recently created image or some old one from like 5 years ago?

The secret image was in black and white I think, and I think it was either a G4 version of a G1 pony or an oc in it. I think it was grimdark, because it delved into psychological horror that somewhat broke the fourth wall near the end.  
Nevermind, I ended up finding it after a long search on Fimfiction.
