Registration Is Open!

Hello friends!

We’re sorry it took so long, but we’re here to tell you that registration and hotel booking for Mysterium 2023 are officially OPEN!

Before we jump in, a quick reminder for your travel/booking plans: Spokane years are action packed, so ending at mid-day on Sunday just doesn’t cut it. Expect events to go until ~4pm on Sunday.


We’re trialing a new (to us) registration system this year. It should make registering easier, and includes the ability for us to offer easier pre-orders on swag. You can also log back in at anytime and review or edit your registration and purchase information.

Please note that t-shirts and early-bird pricing for registration will be only be available through March 31st. Starting in April, shirt sales will close, and the price for registration will increase.

You can get all the details and register over on our registration page.

Hotel Rooms

Similarly, head over to our location page to get all the details about our hotel. Hotel prices in Spokane, and around the country, have gone way up in the last couple of years. We know $149/night is pricier than what we usually aim for, but believe us when we say that this is a good deal for the Spokane area. If you need to split costs by sharing a room, consider posting in the #looking-for-people channel on our Discord server.

Covid-19 Policy

We wish it were gone, but Covid is still with us. So, as with last year, we have a policy in place. You can read all the details here, but the short version is:

  • Full vaccination is required, including a bivalent booster, by June 23rd
  • Masking will be required and enforced in Mysterium spaces
  • No exceptions – we’ll be streaming/recording most events for those who cannot attend
  • Cyan will have their own policy for our time at their headquarters (more on that soon)


Oh, did we mention swag? That’s right! We don’t just have shirts this year, we also have mugs, prints, and lanyard charms available for pre-order. We’re also cooking up some other goodies that might get added later, but for now you can check out all our available swag over here.

Accessibility Survey

We are always striving to make Mysterium as welcoming and accessible to as many people as possible. To that end, we’re putting out an accessibility survey to solicit feedback and ideas. We want to know what you’ve seen/experienced that worked well, what worked poorly, services we should look into, and concerns you have about accessibility at Mysterium.

The survey is short, and all questions are optional. So if you have a few minutes, please consider sending us your thoughts! You can find the survey here.

Submissions Reminder

A quick reminder that submissions are still open for both events and pin designs. Be quick, though, because pin designs are due by February 12th!

December Prompt Winner

As with last month, we once again had our Discord community vote on their favorite entry for our December prompt, “endings”. The winner was Grayson aka redwoodrroad, who submitted this animation of a scene from Riven:

Our January prompt, “beginnings”, is still open until the end of the month. So be sure to drop by our Discord and submit your work!

That’s all we have for now. Stay tuned for more news soon!

End of Year News

Shorah everyone!

It’s been a while since you’ve heard from us. We know you all want to know when we’ll be announcing the hotel and opening registration – things are moving forward there, and we expect to announce that in mid-January. In the meantime, here are some updates, announcements, and reminders:

Pin Submissions

As in recent years, we’re going to make a batch of exclusive enamel pins for Mysterium, and we invite you to submit your designs.

The community has made some amazing designs in past years, and we can’t wait to see what you come up with! Submissions are open until February 12th. Check out all the details here.

Other Submissions

Reminder that submissions for shirt designs and events are currently open. Shirt design submissions close on January 7th, so be sure to get them in by then!

Community Prompt Winners

We have two prompt winners to announce in this post. First, October. We received a bunch of great submissions for October’s topic of “Spooky”, including a few from some newcomers to these prompts. We’re happy to announce the winner is IwonK!

Next, for the month of November and the topic of “Fall”, we decided to try something a little different and let the community vote on their favorite. By a close vote, laughingpineapple’s Yeesha took the lead!

Submissions for this month’s prompt, “Endings”, are still open on our Discord. We’ll be continuing the community voting going forward, so check there in January to vote on the December submissions.

Policy Updates

Lastly, we’ve made some updates to our policies. As always, you can find all of our policies here, but below is a rundown of the major changes:

  • Privacy Policy
    • Added new Room Block section, detailing information the hotel may share with us
  • Other Policies
    • Adjusted how ages are handled for the minor and drugs/alcohol policies, to take into account legal age limits other than US federal ones
    • Added ‘medical devices’ to the harassment policy
    • Added a badge replacement policy
    • Updated photo/video policy to include language about official recording/streaming
    • Added an animals policy
    • Added a sales policy

That’s all we have for now – be sure to check back in January for more. Until then, we hope you all have a happy new year, and that you stay safe and healthy.

Mysterium 2023 Kickoff

Greetings friends,

Fall has started and spooky season is upon us, so it’s time to formally kickoff Mysterium 2023 planning! Let’s jump right in:

Mysterium 2023 Dates

We know everyone has been anxiously awaiting the dates for next year’s event, and the wait is now over. Mysterium will take place from June 30 to July 2, 2023.

“But wait!” we hear you cry. “Mysterium is always at the beginning of August!” Well, that’s true, we always aim for early August (or late July if necessary), but our hands were tied this year. It turns out that Spokane has become a popular city for events since we were last there, and they were basically booked solid for July and August. So we took the best compromise we could find, and snagged this weekend just before the 4th of July.

We can’t give you all of the hotel details yet, but we want to give you a heads-up that Spokane’s popularity has also resulted in price increases. We’re doing everything we can to keep our room costs down where our attendees expect (many thanks to our master negotiator Odo!), but plan for rooms to be pricier than usual. Not astronomically high, mind you, just higher than usual.

We promise we’ll get you more details as we have them, so stay tuned!

Mysterium Theme

As you may know, 2023 marks the 30th anniversary of Myst’s release. In honor of that milestone, we’ve chosen to make this year’s theme ‘The Evolution of Myst‘.

That’s not just talking about the age of Myst. We mean the game/world as a whole. There have been many revisions and additions to Myst over the years, not least of which is Cyan’s recent version from 2020. The world and the franchise have evolved over the years, and we want to showcase that evolution. Which is a fun segue into our next topic…


Get those creative juices flowing, because we’re opening up a couple submissions today!

First up is t-shirt artwork. Every year we invite the community to create artwork to go on our coveted Mysterium t-shirts. We think there are a lot of cool directions you could take with this year’s theme, and we can’t wait to see what you come up with. You can find all the details on the shirt art submissions page. The deadline is January 7, 2023.

As always, the creators of the winning designs will each receive a free t-shirt. And, similarly to the past couple of years, the shirt design will be added to your wardrobe in Uru!

If you have any questions about the shirt art submissions, don’t hesitate to reach out. You can either email us, or DM Rayne (our resident art wizard) over Discord.

Second, we’re opening up event submissions. Have a project you want to show off? A deep dive into D’ni architecture you want to present? An awesome group activity? Well now is your chance! Head over to our event submissions page and send it over to us. The deadline is April 29, 2023.

Discord Housekeeping

We recently performed some minor housekeeping in our community Discord server. Most importantly, we’ve revised and clarified our server rules. There shouldn’t be any big surprises – most of this was codifying what we had already enforced – but please check out our #rules and #announcements channels when you have a chance.

We are also now a verified server, which means we get a fancy custom invite link. So if you have friends that haven’t joined yet, send them over to!

September Prompt Winner

We received 4 wonderful submissions to September’s prompt of “Rest/Sleep.” It was tough selecting a winner, but laughingpineapple‘s submission of a very tired Atrus just edged ahead:

There’s still time to submit something for our October prompt (“Spooky”) – head over to the Mysterium Discord to find out all the details.

That’s all for now. We’ll have more updates for you in the coming weeks and months.

Stay healthy out there!

Mysterium Returns Home

Hello all! This will be my last blog post for quite some time (you can stop celebrating now), as I am handing off the reins to next year’s co-chairs - although first a few 2022 housekeeping details.

YouTube Videos

If you’d like to relive any moments from this past year’s convention, all YouTube videos from Mysterium 2022 are now available on our channel.

Survey Highlights

Thank you to everyone who filled out our 2022 survey. There were a few responses we’d like to highlight:
  • Meow Wolf went over quite well. We’ll look into similar excursions for future locations. (Chair’s note: I’m really glad people enjoyed this. I went there in January and my immediate reaction was “we have to do this during Mysterium”).
  • Cavern Feud was well-received. We’ll see if we can come up with enough questions to do it again, but regardless, we’ll aim for any game show events to involve larger groups like this.
  • A number of people asked about the possibility of ASL or captions. An ASL translator is most likely out of our budget; however, while we cannot yet make any promises, we are looking into captioning options for 2023.

August Prompt Winner

We received what might have been a record number of submissions for August’s topic of "Travel" and this was not an easy one to choose. However, we ultimately had to go with laughingpineapple’s submission of the three siblings on a trip together:

Mysterium 2023

As you may have heard at the end of this year’s Mysterium, we will be heading to Spokane for 2023! Cyan has once again invited us to their area, and we hope to see you all join us there. We have not yet determined dates, but we hope to announce those sometime this fall. That said, I’d like to introduce you to next year’s co-chairs:

Elliot "Taniith" Borenstein - Known primarily for chairing several Mysteria over the past 10+ years, you may also recognize him from his brief stint in the early 90s on the hit U62 show, "Cooking With Esher". Despite saying in 2019 that he would never chair a Spokane year again, his plan to talk Kelly into the role backfired spectacularly, leading to their partnership this year.
Kelly "Rayne" Coston - Kelly hails from the Pacific Northwest and has been drawing since she could crawl. Her days are usually filled with coffee, running a small business, and staring at her screen until art magically appears. Her evenings are usually filled with husband or cat snuggles and video games. A long-time Myst fan, she discovered her Myst family in 2014 and quickly joined the staff as the primary Creator of All Things Pretty and the Tormenter of Attendees on the Puzzle Team. She and the other members of the Puzzle Team are looking forward to tormenting attendees with brain melting puzzles this year!

Once again, thank you to all who joined us for Mysterium 2022 in Denver, whether in person or online. I’m glad I was able to welcome so many of you here, and look forward to seeing you all in Spokane.
