The SCRINIARII Code is the conjectural title given to a series of ongoing puzzles involving the Reddit user Scriniarii and the TribeTwelve subreddit in conjunction with the TribeTwelve Discord server.


Node I

1.1, 1.2

The account scriniarii was created on June 4th, 2016. After the account was created, the user posted a number of odd posts to the TribeTwelve subreddit, entitled "Hello", "Please help, don't ignore", and "He won't let me say more. Please. He's getting angry.". Moderators accused Scriniarii of being an impostor and deleted his posts, though his posts were later restored following the decoding of the puzzles.

Later, Scriniarii posted into a Discord group asking for a keyword. He also messaged a user by the name of Pegaflop.

In late September, the video SCRINIARII was posted to the TribeTwelve YouTube channel. As a result, the subreddit clamored to retrieve the deleted posts.

Reddit user BedrockPerson retrieved the posts using cached copies of the site, re-revealing that each post contained the same message, "I am Scriniarii. You are sensum. You are required. The loop must be maintained. The sensum will take the keyword and submit it to the archive."

At this point, several Reddit users created a group dedicated to decoding the riddles. It was eventually discovered that lead to a secret video, 1.1, containing a slow-scan television image of a screenshot from The Token Letter of Noah holding a fortune that has been completely censored out with one of the censored words circled in red. The word circled in the fortune was "darkness", a keyword to Scriniarii. If one goes to "", it leads to a pastebin with a code in ASCII85 that decodes to a BASE64 code, which, when run through several iterations of BASE64, decodes to the URL of a second secret video, 1.2, revealing page "2 of 2" of the East Coast Assembly Manifest from 1985, along with a message from Scriniarii: "A fragment has been exposed. Sensum has woken. The loop must be maintained. End of node. ~ Scriniarii".

This second page of the East Coast Assembly Manifest reveals additional information about Henka Visæ, a member of "The Order" (a cult that worships the Administrator), mentioned by the Overseer as being the recruiter of Mary Asher.

On October 7th, 2016, Scriniarii posted to the TribeTwelve Discord server again, this time saying:

"In 7 days I will return.
You may ask one question at that time.
Prepare your inquiry."
He also posted to the TribeTwelve subreddit, asking the users to appoint a "delegate" to ask the chosen question. The users of the subreddit also voted on which question to ask him.

One week later, on October 14th, Scriniarii returned to Discord. This is his exchange with the chosen delegate, Combinia, the admin of the TribeTwelve Discord server:

Scriniarii: Name your Delegate.
Combinia: That would be me, I have been selected to ask the question
Scriniarii: Delegate state the decided inquiry.
Combinia: A poll was made, and this was the most popular question:
Combinia: What info can you give us that Noah does not yet know, but needs to?
Scriniarii: All of it.
Scriniarii: In fact I was thinking that you might have asked me about the boat captain or the nazi journal but apparently you like getting information from puzzles and games rather than directly asking for them. I guess I'll hide some more.
Scriniarii: I'll soon return with your next task.
Scriniarii then left the server once more.

The next day, Scriniarii made a post to Reddit-- a full color image of the journal. A nearly identical image was sent to Combinia, but the images were slightly different from one another. The image posted to Reddit was a .jpeg file, the one sent to Combinia was .jpg.

Upon examining the differences in the source code of these two images, the following message was found:

"So I'm going to get punished for talking out of turn but you need this.
You are not individual sensum, you are all collectively the singular sense. You are the eyes and ears of the loop. You are what stabilizes it.
Look I've been doing this over and over for so long. I'm tired. Everyone I have ever loved is gone because of me and I'm doomed to relive their deaths over and over every fucking recursion because you can't get your shit together and stop trying to be individuals. Maybe I just fucked this up and we will have to reset again, maybe you just needed this push.
You ask the same question every time and we have always tried to fill it with the answer that gives you what you need.
We tried giving you everything and that almost collapsed the loop. Why do you think the observer is called that?
You are Sensum. You take this apart and gain understanding. Do you get it? You are on the outside safe from the administrator and we need you. I need you. I don't know how much longer I can do this.
Just wait for the next node to present itself, we have set windows that we can use and can't provide them as they might see."
Some time after this engagement, Discord user Cinder (Darkra1n on Reddit) created a timeline of known events in the series, dating from 1944 to the present day. Just a few minutes later, Scriniarii posted to Reddit with a thread titled "gratias tibi", Latin for "thank you". In the post, he left a message encrypted with a Vigenère cipher. Upon applying the keyword, "keyword", the following message was translated:

"our mutual friend thanks you for your work. i also apologize for the theatrics, they might be listening after all. keep building the archive. now that you are beginning to understand the loop you can begin to maintain it. the more detail the better. we will be in touch."
Some time after, the URL was created, and redirects to this same timeline, establishing it as the canonical archive described by Scriniarii.

On October 28th, Scriniarii returned to Reddit, posting a thread titled "loop". In it, he posted a string of letters and numbers. Split in half, these strings correspond to the video IDs of two YouTube videos, both by Vsauce3.

The first video, titled "3 Time Travel Paradoxes!!", talks about three different types of paradoxes associated with time travel.

  • The first is the Bootstrap Paradox, which states that objects involved in time travel may not necessarily have an origin, as an existing object from the future may be taken back to the past, where it could continue to exist until the point at which it is taken back again.
  • The second is the Predestination Paradox, which states that any attempt by a time traveler to prevent an event in the past from happening could instead be what causes the event in the first place.
  • Before moving on to the final paradox, the video goes on to discuss more repercussions of time travel, such as the Butterfly Effect, which means minor actions may lead to a domino effect of changes that result in the future being completely different. Also mentioned is the idea of time as a closed loop, meaning that any changes made to a timeline could very well end in the exact same result.
  • The third and final paradox mentioned is the Grandfather Paradox, which states that if one were to go back in time to kill their grandfather, their father would not be born, meaning they would not be born, meaning they would not be able to kill their grandfather.

The second video is titled "Causal Loop". It explains the different types of time travel discussed in fiction and pop culture.

  • The first form of time travel mentioned is mental time travel, or MTT. This is a situation in which the time traveler's body doesn't travel through time, but the mind does. While not allowing the time traveler to alter or interact directly with past events, MTT can give them insight into future events. A weakness of MTT is the Cassandra Dilemma, meaning that any warning of the future has a tendency to be ignored.
  • The second form of time travel is VHS time travel. Again, the time traveler cannot interfere with the events of the timeline, but they are able to view the past and future like a VHS tape, "fast-forwarding" and "rewinding" across a single timeline.
  • In between discussion of forms of time travel, the video mentions the concept of time loops, or recursive intervals of time in which one action leads to the next, and the final action leads to the first, if not being the first action itself. As a result, time loops repeat infinitely. Since causal loops are unchanging, nobody in the loop has true freedom of action, and their actions are set in stone with no alternative.
  • The third and final form of time travel is the wormhole. A wormhole is a theoretical portal that has the potential to take a person from one point in space and time to another, serving as a bridge between those two points.

On November 11th, the same day on which Noah started the Maxwell Archive where Milo's journal would be posted, Scriniarii made a Reddit post titled "Learn the symbol". The body text reads "Protect the archive, protect the loop." The subreddit's users responded by posting the Severance symbol to the archive, the background of the subreddit, and the header of the TribeTwelve wiki.

Node 2


On April 21st, 2017, Scriniarii returned to the Discord, hinting at another forthcoming piece to the puzzle:

"The next keyword is bigger and more frightening than it should be."
After searching, the Discord was able to find the next keyword, "spider". The URL leads to a Google Form titled "2.1". With it, users were prompted to submit their name, address, Discord name, and answer to a question: "Do you vow to disclose everything, or risk being exposed?"

Soon after, Scriniarii returned to the Discord server with the following message:

"Select 5 delegates as potential candidate to receive the device
We will verify eligibility
Delegates must create or own a YouTube channel
Delegates must be able to share the device in high detail
Delegates must have unrestricted access to physical mail.
Delegates must be dedicated to the will of sensum and vow to not speak as figureheads but representatives.
Top candidate will receive device.
Selection : 5 12 @174"
He returned the next day with another message:
"One question will be answered between @952-@955 but not after. We are watching."
After deliberation, sensum responded with the following question: "Who is Henka Visæ?"

Scriniarii then answered:

"Henka is interesting figure in the timeline. He is the Boat Captain and the Child Seeker. The one that brought the ones closest to me much suffering. The device will help you begin to understand what suffering he has brought and to see just what extent he will go for his own misinformed quest. As Noah is too busy with his homework to share so I'll let you see his current assignment when you complete the second node. As for now, I am very pleased that you now understand temporal notation. This tool will help you in the future. You and He have both learned a lot recently, let's see if I can teach you more. Finalize your selections and have the list for me before 5 12 @174"


Finally, a delegate, Maligerent, was chosen and the device was shipped to her. Taking the form of a circuit board with a switch, the device played an audio file similar to a number station transmission. The users of the Discord server began to fight over how to find the solution, and it reached a point to where Scriniarii had to intervene, giving sensum clues while also stating:

"Do you know what a collapse is like? It's like Groundhog Day but no chance at a happy fucking ending where you get the girl and the snow has melted. I've tried just telling you shit in the past and a few special snowflakes either hoard the information or claim to be experts on shit they don't fucking know. You still don't even truly understand severance. I'm not going to get started with how many times you collapsed because you locked me out or let them in. Took Noah so long to get it right as you'll see."
Finally, the Discord was able to solve the code, leading to the next hidden video, 2.3.


2.3 is notably not posted to Noah's actual channel, but a different channel that's been around for longer: Breakmaster Cylinder. The video is a sped-up black and white video of the boardwalk, with looping and reversing speed. The audio is of a piano track, which was converted to a cryptogram spelling out a message: "This version knows more than it can say. The keyword is the serial number."

Upon solving the puzzle, Scriniarii posted the following:

"See was that so hard? Now focus on Noah, take a break, reflect on all that has been, and get ready for what will be.
It won't be long now before he breaks down and starts to tell you of his ordeal. There you will find answers. While you are variable, he is predictable. With you helping to corral him he can't help but react. He has been marked and has learned some of what you wish to. He thought he could drown it out but that never works. With time he'll come to understand. You are helping. And now that you are working together you are stronger.
You are far from done but now you wait for him.
The Archive keeps facts straight. Things in order as they should be. That's why we wait. He's not ready, but you will be.
When you can name the contents of the bag, you get to pick something out of it. I bet I know what. Rest."


  • It is currently unknown whether or not Scriniarii himself is a member of the Collective.
  • There a theory where Firebrand (Future Noah) met Scriniarii sometime before he became a part of the collective, and either of these two things could have happened:
    1. After Noah became Firebrand, the Administrator got to Scriniarii later. Scriniarii and Firebrand went to the past, and after a period of time, Scriniarii became the archivist.
    2. After Noah became Firebrand, The Administrator sent Firebrand to get Scriniarii and the rest occurs as number one does.
