Mysterium Dates

Hi all. We do indeed have dates for Mysterium 2024! Read on for details.

Mysterium 2024 Dates

Mysterium 2024 will be held July 12-14. We expect to have hotel information in the near future, but these dates are now official. Since this is a little earlier than usual, the deadline for Writing and Artwork table submissions is now June 30 instead of July 12.


To give people ample time to plan, we’ve decided to set a COVID policy now, at the same time we’re announcing dates for the convention. Details are available on our COVID page, but in summary:
  • Masks are required
  • Vaccines are not required

December Prompt Winners

For December’s topic of “Refuge”, redwoodrroad submitted this image of Gehn’s refuge on K’veer:

The written winner this month was Talashar, with “Dream Island”

T-Shirt Reminder

Reminder that t-shirt submissions are open for a few more weeks, until February 25. Submit your designs! See our Submissions page for more information.

We will have quite a bit more to announce soon, including event submissions and hotel information. Hope to see you all in Montreal!

A December Update

Hello. We really were hoping to announce dates in this post. However, we ran into a major issue with the weekend we were aiming for. This is probably a disappointing revelation, but we’re trying to minimize the cost of attending while still considering the accessibility and convenience of a location.


We are still weighing various trade-offs for dates and costs. To gauge where attendees stand, we’ve put together a brief survey that will help us make a decision. Please fill it out – it should only take a minute or two:

AI Content Policy

We made a slight update to our policies: we have added this line to the Submissions policy:
Submissions generated by Artificial Intelligence tools are not permitted. AI may be used for brainstorming but the final product must be your own original work. This applies to all submission types including both visual and written works.
This applies to any content that adheres to our submissions policy, including t-shirts, pins, and Discord community prompts. The full policy is available on our website.

November Prompt

There were a few ties for the month of November and the topic of “Found Family”. Normally I’d have the tie-breaker vote but due to the obvious conflict of interest, we’re just going to highlight everyone’s submissions instead of announcing winners.
redwoodrroad once again submitted a fantastic piece of artwork, this time featuring Yeesha’s found family:
We also had four stories this month:
Remember: today is the last day for December’s topic of “Refuge”.

We are still negotiating with hotels and hope to be able to announce dates soon. In the meantime, happy new year!

Policy Updates

Happy (belated) Thanksgiving! We have a couple quick items to announce. No, we do not have dates for Mysterium yet but are close and expect to announce that before the end of the year.

Policy Updates

We made a few changes to the Mysterium policies. Note the following:
  • We received some complaints about heckling and shouting out during presentations. While audience reactions and cheering are fine, repeatedly interrupting presenters is not.
  • Attempts to circumvent our refund policies via charge dispute may result in a permanent ban from future events.
The full set of policies is available on the Policies page of our website.

October Prompt Winners

We have our two winners for October’s community prompt topic of “Noir”. First, the visual winner angelmyst with this photo collage:


“There it stood, in all its splendor, pulling me to its craggy feet. Not just a mountain, The mountain. The mountain of my dreams…calling, ever calling. My childhood games were all compassed in its majesty. I had to see what it held.
Home, cozy and dark, it enveloped me in its depths, and held me breathless. Echos from my past played on the vaulted ceiling.
I shall never leave.
I can never leave.
I am its prisoner.”

Next, Talashar was selected as the written winner with “The Hidden Way”.
There are still a few days to submit entries for November’s topic of “Found Family”.

That’s it for this one. Again, we expect to have dates very soon and should be following up with another post in December.

Writing & Artwork

Greetings from snowy Colorado! Yes, snowy. We just saw our first snowfall of the season. We have more submissions open plus another round of prompt winners.

Writing and Artwork Submissions

In addition to co-chairing this year, Annacat has once again graciously offered to run the writing and artwork table. We have decided to add a limit of 5 pages for any printouts to save the trees and wallets. If your piece is longer you may wish to direct people to a website or other location where they can read the full text. See the Writing & Art Table Submissions page for details.

September Creativity Prompt

We had some more great submissions for the month of September. This month’s written winner was Salvo Ludus with the story “The Linking Game”.
The visual art winner was Grayson aka redwoodrroad with this image of a young Gehn at his desk:
There are still a couple more days for October’s topic of “Noir”.

More announcements to come, but for now, happy Halloween!

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

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!
