Hello all! We have a few more items to announce.


First, we’re opening pin submissions for Mysterium 2024. For more information see the Submissions page. Pins are not required to follow the Mysterium theme, but if you’d like to incorporate it, remember this year’s is Serenia.

August Creativity Prompt

We are continuing to showcase two winners. This month the visual art winner was laughingpineapple with “Blazing Mentor”.
Blazing Mentor

The written winner was Salvo Ludus with the story “The Bad Ending”.

September’s prompt has now closed, but there’s a whole month to submit entries for October’s topic of “Noir”!

COVID Vaccines

We wanted to give a quick notice for anyone who hasn’t seen: there is a new COVID vaccine available as of last month for the latest variants of the virus. We’d recommend everyone obtain it when you can!
Additionally, we have received reports of pharmacies no longer updating or providing vaccine cards. If you are looking for an updated proof of vaccine, then it is advisable to specifically request a card if possible, or look into electronic vaccine records if available for your location.

We’ll have more to share in the coming months. In the meantime, happy spooky month!

T-Shirts and Passports

Shorah! We’re getting underway with planning for Mysterium 2024 and have a few updates to provide.

Traveling to Canada

Since Mysterium will be in Canada next year, it’s important to pay attention to any immigration requirements. There are a few links on the Location page to help direct you. Most importantly: if you don’t have a passport, don’t procrastinate, since it can take a few months for the application to be processed.
Also, and this cannot be overstressed: rely on official sources for immigration information. We are simply providing these links for convenience. Do not rely on advice from our Discord server or any other unofficial source.

2024 Theme and T-Shirt Designs

We have chosen a theme for Mysterium! Since this will be the 20th anniversary of Revelation, we’re going with Serenia (think of Montreal’s waterways).
On that note, we’re also opening t-shirt design submissions. Submissions will be accepted until February 25. Details are available on the T-shirt design page but in general we will look favorably upon designs that incorporate this year’s theme and the host city.

July Creativity Prompt

In recognition of the variety of creative submissions we receive, we decided to choose two winners for July’s topic of Sun: one for visual, and one for written.
The written winner is Salvo Ludus with the story “Gehn’s Sun”.

The visual winner is Grayson aka redwoodrroad for this image of Gehn’s lab with the sunlight streaming in through the windows:

There are still a few days left for August’s topic of Blazing.
That’s it for now! We’ll have more soon on additional submissions and 2024 logistics.

2024 Kick-off

It’s summertime and we’re already in full swing for planning 2024 Mysterium! Before we dive into that, however, we wanted to share some of the highlights from the 2023 survey that we sent out as well as some other goodies.

Survey Highlights

We work hard to improve Mysterium every year and appreciate the feedback you have been sending in. Some of our experiments work, and sometimes they don’t and need some tweaks, but we always strive to make the experience better. We had a lot of fantastic suggestions and we will definitely consider them for future years!

Some of the highlights of the results:

  • Swag: Pre-ordering the swag was a huge hit! This was a bit of an experiment this year. We were using a new system for registration that allowed us to print badge numbers, pre-order swag, print labels for the swag bags, and pack them in a super-efficient manner, and an all-around amazing system! We will definitely be using this again.
  • Paypal: We had quite a few people ask for Paypal support. Unfortunately, they are, how shall we put this politely, very unkind to organizations like Mysterium. We need to stick to using Square and Stripe for our credit card processing portals.
  • The noise level in the con room: Yep, we hear you. It was frustrating for us too and we’re looking into options on how to improve that.
  • Accessibility: We try to make Mysterium accessible and there were some great suggestions on some things we can tweak! Thank you so much for sending those in!
  • Covid policy: We strive to make Mysterium a safe environment for everyone and appreciate the feedback on our policy. It’s too early to anticipate what 2024’s policy will involve, but our hope is that we can find some solutions that will be more inclusive.
  • Newsletter: The newsletter got a surprising amount of support! Alright, we’ll take a look at doing that this year! We want you to get the information we send out. 🙂

June’s Prompt Winner

June’s creative prompt was “Scream!” as Mysterium drew closer. The winner was redwoodrroad, who submitted this little beauty:

Youtube videos

All of the videos from Mysterium 2023 are now available on our Youtube channel! Check it out here.


We promised, so here they are! The 3D model files for the maze boxes and cryptexes, puzzle packets, and other downloadable files are now available on the website. More items will be added in the future! Please feel free to check them out here: Downloadables

Planning for 2024

If you missed the announcement, Mysterium will be in Canada next year. As exciting as that is, it also means that you will need to plan ahead for international travel. If you do not have a passport, we recommend that you get an early jump on it, as the turnaround time is taking longer than ideal.

More information may be found on the Department of State website:

2024 Kick-off

And without further ado, we’d like to introduce you to your con-chairs for 2024.

Dan Binder (Fused Shadow) –

Dan first attended Mysterium in Orlando in 2017, then after a night at a tiki bar apparently agreed to join staff the following year (details are still a little hazy).

You’ll most likely encounter him working on the Mysterium website and/or posting on the Discord server, the latter especially if someone happens to mention Twilight Princess.

If you’re seeking him out in person, you can find him on a hiking trail or ski slope, or petting the nearest dog.

Hannah Catherine Mills-Woolsey (Annacat) –

Annacat attended her first Mysterium in Philadelphia in 2002, has been part of the Mysterium Committee since 2019, and has become the con’s self-appointed expert on all things Narayan-related. For her day job, she is a supervisor and instructor at a Vocational Education program for people with disabilities.

Her hobbies include participating in community theater, coaching a Special Olympics dance team, hiking, camping, kayaking, and loving every single animal in the world.

2023 Wrap-Up

Wow, y’all! That was quite a weekend!!
First of all, an enormous thank you to everyone who came to join us at Mysterium this year. We had a record year and the largest crowd Mysterium has ever seen! It was truly a pleasure to be able to celebrate 30 years of Myst with you all.


Every year we try to make Mysterium a little better. To that end, we’ve put together a survey to gather your thoughts and feedback. Please take a moment and fill it out! The Survey.

Photos with Rand

Did you have your photo taken with Rand? Great! We will have digital copies available until the end of July. The group photo we took at Cyan is also up here, so please snag your photo while they’re up! The Photos.

Friends of Mysterium

We’ve got a lot of great folks at Mysterium who make some pretty amazing things. And they need your help!

Dan’s Good Cookies

If you visited Cyan this year, you probably got to enjoy one (or three) of Dan’s amazing cookies! He has also put together a survey and would appreciate feedback from you! Dan’s Survey.
What was your favorite kind of cookie?


Did you participate in one of the Unwritten sessions over the weekend? Are you interested in playing more? Good news! They launched a Kickstarter campaign to fund a sourcebook called Modern D’ni! This book expands beyond the initial core rulebook diving deeper into the present-day era of the Cavern! They even have an exclusive hardcover of the Core Rulebook as a reward for one of the tiers which was previously only available during the initial Unwritten kickstarter. Check it out over at Kickstarter.

Video Game History Foundation

Ok we have to admit, that was one of the coolest presentations we’ve ever seen! In case you missed it, the amazing folks over at the Video Game History Foundation are working directly with Cyan to restore, digitally archive, and preserve their entire video archive. Yes, this includes the old VHS tapes with original Riven footage. However, they need funding to achieve this remarkable goal. More information may be found here: Video Game History Foundation.

Whew! What a weekend!
Post-con blues are a thing, folks. Please be kind to yourself. Hydrate. We love you.

And hopefully, we’ll see you again next year in Montreal! Wait, Montreal? In case you missed it, yes! We will be in Montreal next year! Take a look at the announcement here!

2 Weeks Away


We have a few last things to cover before Mysterium, which brings us to our first point:

Mysterium is 2 weeks away!

Scream!! We can’t wait to see everyone, and we’re all hard at work getting last-minute details ironed out. The Committee has a few things to go over with everyone, and we’re all looking forward to our weekend with you.

Registration Closes Tomorrow

Huge reminder to everyone that registration closes tomorrow, Friday, June 16th. While we will have a limited number of standby tickets available to sell at the Registration table, those will be on a first-come, first-served basis on Friday, June 30th only. Stand-By tickets include admission for the weekend, and Mysterium 2023 Lanyard (while supplies last), but DOES NOT include admission to Cyan. Anyone buying a Stand-by ticket (either online, or at the registration table) will have their name placed on a standby list for any last-minute spots that may open up for the Cyan trip on Saturday morning. However, please be aware this does not guarantee a ticket to Cyan.

Bus ticket Deadlines

Bus ticket online sales will end when Registration closes tomorrow, Friday, June 16th. We will be selling the tickets at Mysterium until 8:30am on Saturday July 1st, before leaving for Cyan at 9:00am.

Meet & Greet Details

There will be a few Cyan staff for folks to meet during the Meet & Greet portion of the Cyan visit on Saturday.

For meeting Rand, folks may choose to have either one selfie with Rand or one autograph with Rand. If you choose to have an autograph, it should be a simple autograph without personalization. This is to keep the lines moving and not overwhelm Rand. Please be respectful of Rand’s time during the meet & greet and save your questions for the Q&A panel at 3:00 pm later in the day.

May Prompt Winner

Keith “Tweek” Lord  won the May Prompt! See the submission here:
