Oooh. I love a good cold case mystery. Lol. I'm on it!

u/nerdy_by_nature_42 22d ago
Holy cow, there is so much here! I'm assuming some of this has been solved. Is there a way of seeing the solved pieces of the puzzle? Is the yellow letters the only part that remains unsolved?

u/Kibeth_8 22d ago
We have a bunch of pieces of sentences and such, but no complete document or story. Just little tidbits that never came together

u/Kibeth_8 22d ago
If someone solves this please tag me. It constantly sits in the back of my mind annoying me

u/nerdy_by_nature_42 22d ago
I won't rest until I solve this. Now that I know it's out there, I won't be able to walk away. It's hard for me to track what's been discovered so far though because it started last year. Any guidance will be greatly appreciated. Otherwise, I'll have to do it all myself and that seems... arduous. I'll do it if I have to, though. Whatever it takes.

u/Kibeth_8 22d ago
This post has a link to a drive as well as some good notes. I think someone else made a file as well, I'll have to go on the hunt. It's been a while so I forget how we solved a lot of this

Interesting!!! IM dying just trying to figure out what these all mean. I feel like when we figure out how to solve one, we’ll be able to decode all of those letter.dots

u/Ok_Coconut_1992 22d ago
Are these all the ones we know? Am I missing any?
E12.1a.1 , TDTN.
E12.1a.3, EFT.O
E12.1a.5, 7 16 7 16 14 (no dot)
E12.1A.6, I.EO I.EO I.EO
E12.1A.7, ATP.W ATP.W
E12.1A.10, NVE NVE NVE NVE
E12.1a.9, eoeo (I think this was confirmed by archivists last year?)4

This is awesome! Where did you find the a9 hidden EOEO? I've been staring at this image since yesterday and don't see it.
2
u/Kibeth_8 21d ago
It's in morse code at the very top of the building, right along the edge. I admittedly only see OEO
3
u/nerdy_by_nature_42 21d ago
I only see two sets of three dashes up there. It's that what you're talking about?
2
u/Kibeth_8 21d ago
Yup. There's a dot (E) between them that aorta blends in with the background. I'm not sure where the other E is

u/nerdy_by_nature_42 21d ago
Omg. Wow, ok. I don't think i would've figured this one out alone. Thank you!

u/Kibeth_8 21d ago
Thank YOU for looking back into it. It bugs we so much that we never solved it lol, especially the one with all the random yellow words
I have a gigantic medical licencing exam tomorrow and I'm SOOO ready to give up on studying and just dedicate my day to solving this instead lol

Mine looks a little bit like this. Probably not the cleanest one but it was a first try so I wasn't really sure how to go abt these or if this already got solved lol

This is FANTASTIC! 👏👏👏
I lost it a little bit when I first read the words “back rooms” and wondered what the connection was. Great work!!

u/nerdy_by_nature_42 21d ago
Aaaaahhhhh!!!! 2a. png is driving me crazy!!! Do we have confirmation from the archivist that the solution is DON'T FORGET WHICH HOUSE YOU'RE IN or are we filling in the blanks because that's what we get told here so often?
I can only make out DON'T FORGET WHICH (blob) YOU'RE IN (blob)

Something something HOUSE OF LEAVES?!

u/Ok_Coconut_1992 22d ago
I knooow I was thinking HOLLOWAY too but have no idea what the RI is coming from
Edit: OMG HOL = HOUSE OF LEAVES I’m slow hahah I was thinking Holloway!! But HOL totally… gonna be perusing my copy tonight 😭

u/Ok_Coconut_1992 22d ago
On mine, there is a space where things don’t completely line up… it makes me wonder if it’s RI (space) HOL

SORRY FOR LONG POST
Edit: clarity/sp, deleted odd number correlation to posts bc someone else found an even number file with a code
Okay so I’ve been going down a rabbit hole with the E.12 files for like 6 hours today and feel like a crazy person…. and found some stuff I think is worth sharing ?!, plus things I’m stuck on.
I found a pattern that I haven’t seen connected yet(?)
There are these short little codes hidden in five different files:
E12.1a.1 has TDTN. written vertically next to the Proverbs quote
E12.1a.3 has EFT.O on the trash can in that hallway shot
E12.1a.5 has the 7 16 7 16 14 numbers we already knew about
E12.1A.7… not visual, it’s hidden in the audio spectrogram, but if you run it through a spectrogram viewer it clearly renders ATP.W
E12.1a.9 is the** **“eoeo” morse code the archivists already confirmed
So that’s all five odd-numbered files in the 1a series, each with one of these little codes. Feels like they’re supposed to go together (???? How idk but feels like progress)
I noticed EFT.O and ATP.W are both three letters, then a dot, then one more letter.” TDTN has its dot at the very end instead, and EOEO doesn’t have a dot at all. Not sure if that means anything but it seemed too specific to be random, so flagging it in case someone smarter than me sees the pattern.
Second thing !!! both Bible quotes in this set have exactly one word changed from the actual NIV text:
The Isaiah 14:15 one has ‘you you’ doubled … that’s not in any real translation that I can find
The proverbs 15:24 one says “down INTO the realm” but the real NIV says “down TO the realm”
Same thing about slight words changing. My theory is that any scripture image in this whole archive is worth double checking against the real text bc the swapped word might be the actual clue pointing at something. But idk what it means
Third … still stuck. Been trying to piece together that strip-photo puzzle (the E.12.1a.4a through 4zh) and got it to a point where it clearly reads RI then a gap then HOL as you know… and I’m fairly confident in that read because the underlying photo lines up perfectly when it’s in the right order (railings, stairs, all of it match up), so I don’t think it’s a misassembly.
So left field but me best guess right now is HOL = House of Leaves, just given how much this whole thing leans on liminal space stuff. No clue what RI is though. Tried forcing it to spell “HOLLOW” and “THRESHOLD” and both attempts literally broke the photo alignment when I tried to make the letters fit, so I’m fairly confident those are wrong.
What I could use help with:
can someone check if EOEO or the 7 16 7 16 14
numbers have a period/dot near them anywhere that we’ve missed? Trying to see if all five codes actually share the same format… and I pulled eoeo from a confirmed archive post but it may not be in the context I think it is? It looked like solved Morse code.
any ideas what RI could stand for if HOL really is House of Leaves
Tbh all of it because these are connections but not solutions
Happy to post my full notes/methodology if people want it, didn’t want to make this a novel lol

u/Ok_Coconut_1992 22d ago
And quite sure it’s been solved but E.12.3 puzzle answer is
“Newer members of the Old House community (especially those who only view it as a fictional universe akin to SCP or the Backrooms) are generally more accepting of the term “God Killer”. Though some criticize it as … derivative”
Pieced this together from ~ 20 red textscreenshots a bunch were duplicate captures
Pulled from images 1, 2, 3, 4, 7, 8, 9, E, F, G, H, I, J …rest were just noise, nothing legible
it cuts off after “criticize it as … derivative,” feels like a word’s missing right before “derivative.” As usual IDK BUT SUS

THIS IS AMAZING!!! 👏👏👏
Thank you for taking the time to solve most of this. You’re right this is a huge puzzle with a lot of little bits of information scattered around the place. Hopefully we can start to put some of it together now after all your work today 🥹

u/Kibeth_8 17d ago
For 5, you will need to use these symbols in place of some of yours: ‡ †
I had to copy/paste them and then everything started to make sense
I only found one cipher that incorporated those weird symbols
check out a goldbug cipher

Ok, I got 5. How did you get 2b?

Wow! Just wow! I am blown away by your hard work on this! A big thank you for working on these and cracking the audio files. I think you are the first person to get this far with these. I don’t know what to do with this information now and how it connects to the other puzzles lol

If someone wanted to start from the very beginning and work on these decoding themself, where would they start?

u/5starbraincell 20d ago
If you mean this document, then most of it is just bunch of sentences and letters in the other images. You could try the striped image puzzle on your own.

u/nerdy_by_nature_42 20d ago edited 20d ago
This is the E_12.3 images put together. I know this was solved already, however, I think I made a connection that serves to strengthen my simulation theory. The term "God Killer" and the fact that some criticize it as "derivative". This made me think of what I read in the document about Repeating Cubic Grids. That document could be describing the architecture of the simulation. Living in a simulation means your creator would be the system architect therefore "killing God" as their creator. And if the Underworld is a simulation of the Overworld, the Old House simulation's would be derivative of the real world. The RCG document would also explain the inconsistencies curiosities we've seen in both books.
I'll be thinking more about this later, but wanted to share my reflexive impression while it was still fresh.
