Mysterium 2024

The XXV Mysterium was held in Montréal, Canada on July 12–14, with the panels and presentations streamed to both Twitch and YouTube.

Belford wrote a summary in his blog, giving his perspective on the various updates.


Friday started with the Opening Announcements with a few words and reminders from the convention chairs.

☛ In the Cyan ‘State of the Union’ prerecorded panel Rand Miller, Hannah Gamiel and Eric A. Anderson gave a few updates on their games. While Riven‘s critical reception has been phenomenal, sales have not been correspondly positive. Riven costed “less than 2%” of a AAA game of comparable quality to make; it was a “monumental effort” and they really want to scale down their workload.

Touching on the design process, they started with drastic redesign ideas, narrowing them them down to only those that directly supported the game experience. They also had to iron bugs and glitches quite close to launch.

For the immediate future, they will be working on porting Firmament and Riven to more platforms, and improving Myst on the Quest 3. After that, Rand confirmed they have started on a new game in the D’niverse; it will be a new storyline and you will not have to be familiar with the Myst series to play it. They expect to have more to say next year.

Also, Rand is retiring: with Riven released, he feels it’s the right time to cut back considerably; he will still be involved with advising on game design and such, but not as often and as much.

☛ In the Myst Reverse Engineer panel, Jeff Barbi showed how to hack the original Myst (thanks to Uli Kusterer’s HyperCard work), and a few interesting results of editing the HyperTalk source code. The original fireplace puzzle accepted two codes, from page 158 but also page 148. The HyperCard stack was password-locked against editing, but this feature can easily be bypassed with modern tools, and Jeff was able to recover the original password.

☛ In the Myst Online Update, a group of fan developers (AgeExplorer, Doobes, DPogue, Harley, Semjay and Yali) gave a few updates on what’s been going on in the Cavern. The writing team is trying a long-term story arc (“Diplomacy”) involving first contact with an unexpectedly inhabited Age. On the open source client front, DPogue has continued to improve the Korman Blender plugin, as well as the MacOS client, which however is not yet ready for testing on the live servers.

As for upcoming Ages, Doobes and AgeExplorer are still working on the Descent: you can now take the elevator down the Shaft and mostly solve the puzzles there, and walk down the spiral staircase that runs the entire length of the Shaft. Doobes is also working on a major Chiso expansion. Tweek is working on a library Age, a garden homage to Myst, a rework of of Fahets, and a new Neighborhood. Semjay is working on completing one of Cyan’s cancelled Ages for Uru, Venalem, and also on the Explorer’s Emporium. Harley is working on expanding Naybree and on an Age called Rei’schu. Yali is working on a private city area and on UI updates for the client.

☛ The rest of the day was dedicated to events that were not streamed. In Uru Live, a devious marker mission ws released (video). For Puzzle Time, Rayne and m13 challenged the participants with a set of devious puzzles. For the Dance Event, Annacat explored the music of the Myst series through dance and creative movement, teaching a simple short choreography.


Saturday started with a few events that were not streamed: the Mysterium Unconference, an unstreamed set of participant-driven discussion sessions; What Would Catherine Build? (Atrus was too busy this year!), where teams were asked to build something that met certain requirements, and delivered clever presentations for why they built like that.

The subsequent three panels were all about Myst IV: Revelation:

☛ In the Designing Worlds panel, Patrick Fortier (Creative Director & Lead Game Designer), Mary DeMarle (Designer & Writer), Sebastien Yelle (Level Designer) and moderator Katie “Khatie” Postma (Community Manager) discussed bringing Myst IV’s world to life, the creative process, technical challenges and innovative design choices.

☛ In the Living Worlds panel, Meinert Hansen (Senior Art Director) and Guy Sprung (Actor for Achenar) shared their experience bringing the worlds and characters of Myst IV to life through visuals, sound, and motion.

☛ In the Retrospection panel, Mary DeMarle, Patrick Fortier, Meinert Hansen, Katie “Kha’tie” Postma, Guy Sprung and Sebastien Yellel shared behind-the-scenes insights, stories and the creative processes that brought the game to launch.

☛ The rest of the day was dedicated to events that were not streamed. In the Guildmaster event, Taerun assigned the participants a variety of unique tasks to complete.


Sunday started with the Myst Documentary panel, where Philip Shane (filmmaker), Katie “Kha’tie” Postma and Joshua Reinstein gave the latest updates and showed some footage of the Riven launch event at Cyan HQ. The documentary is having trouble funding the full production. David Van Taylor was brought in to help with pitching, and Julie McElmurry is helping with production. The working title now is “A World I’d Want To Live In: Myst and the Video-Game Revolution“.

☛ The Closing Ceremonies wrapped up this year’s convention, running the prize drawing, and announced next year’s location: Atlanta, GA!

☛ After the Closing Ceremonies, attendees joined unofficial excursions to see some of Montréal’s many attractions, including the Biodôme and the Jardin Botanique.


Thanks and kudos to the Mysterium Committee, who did a great job at organising and managing the event.

Looking forward to next year!
