It’s Gonna Be May!

Shorah Everyone!

Mysterium is only two months away (cue the screaming here) and we of the committee are excited to see all of you come June 30th! That being said, we have a couple of reminders for you!


  • Book your hotel room before the closing date on May 28th. If you reserve your room after that date, the code for the rooms will no longer work and you’ll have to pay the full hotel price. Reservations for the rooms can be found here. Any further information about the hotel can be found on our location page of our website.
  • Our cut-off date for swag is June 3rd! Any orders not finalized by this date will be unavailable. There will be a limited number of swag items at the registration table available for purchase on a first come, first serve basis.
  • Online Registration ends on June 16th. While we will allow walk-in registration at the door for 50$, we ask that you register before the deadline so that we can get an accurate head count for Cyan.

Which brings us to our next point…

Assisted Listening

This year, for the first time, Mysterium will be renting and offering assistive listening technology. We will be using Williams Sound PPA 457 Personal Assistive Listening System, so if you require one of these, please contact the committee through the email ASAP (by no later than June 1st) so we can compile a headcount for the use of these. During the convention, please check in at the registration desk to pick yours up, but bear in mind that we will be requiring either a deposit or a form of collateral from you.

May’s Creative Prompt

And lastly, our Prompt for May is: Spring. (Give us all the plays on words, all the puns you can think of. No holds barred pun challenge is a go!)

We’ll be coming back to you soon with more information on a schedule, our final headcount, and any other important information, so be on the lookout.

Until then,
m13, Co-Chair of Mysterium 2023

Event Submissions and More!

Shorah and happy weekend!

Mysterium is approaching quickly and we have a couple of quick announcements. 

Event Submissions Last Call

Event submissions are closing on April 29th at midnight, so if you have a presentation idea you’d like to share, please send that in! The morning of the 30th we will lock submissions and begin to finalize the schedule. If you have an event you’d like to submit, please check out the Event Submissions page.

Table Submissions Still Open

We still have openings for The Table (writing and art table) submissions! A perfect opportunity to show off your work without having to stand up in front of everyone. Please check out The Table submissions page for more information.

COVID Policy Update

As of April 18th, the FDA has simplified the COVID vaccination. Initial doses of the vaccine will no longer be available and US attendees will be considered fully vaccinated if they have received a bivalent dose as long as it was between the dates of September 2, 2022 and June 23, 2023. For more information, please check out the FDA announcement as well as our COVID Policy page.
Note: this change only applies to attendees from the United States. Attendees from abroad should follow the existing policy.

Another note: If you’ve already registered, you may receive an email from our registration system with the updated policy.

March Creative Prompt Winner

And last but not least, March’s “Idle Hands” prompt! We had a lot of great submissions, but Kefrith’s Gemedet set took the cake.

We’ve got a lot of great stuff in the works so please stay tuned!

Much love,
– Kelly “Rayne” & Drea “m13”

Mid-March Update

Things are moving along very nicely on our end, and we have a couple of things we wanted to share with you real quick.

Early Bird Registration Closing Soon!

Just a reminder that early bird registration and shirt orders close at the end of March.
Starting April 1st:
– Other swag items may still be purchased until June 3rd.
– Regular registration will be open until June 16th. Regular registration is slightly more expensive, so if you’re on the fence about coming to Mysterium, now’s the time!
Head on over to the registration page to get started!

February’s Prompt Winner

We had some great submissions for February’s “Heart” prompt!
“Shadow” Dan submitted a fantastic Exile/Undertale crossover with pixel art by Kevin F. “Kefrith” Smith.

March’s prompt is “Idle hands” and submissions are still open for that one! Head on over to the “prompt-submissions” channel on our discord server if you have something you’d like to share!
That’s all for today. Have a spectacular weekend!

Pins and Buttons, Oh My!


The snow is melting, and we have some swag announcements to share with you!

Enamel Pins

We got a lot of fantastic pin submissions this year! We chose four designs to have available at Mysterium.

We all began this journey with the fissure! The Fissure design is by Katherine “Squeefruit” White. You can see her work here:

The Black Ships design is by Kelly “Rayne” Coston. Her website can be found here: Geek Girl Stuff

The Scarab design is by redwoodrroad. You can visit his website at

And the Clockwork Adjunct design is by Avior. You can see their other work at:


We’re rolling out some brand-new swag items this year! One of them is 1.25” buttons, featuring art submitted by Neil Darbyshire and Kefrith. The buttons will be sold as a set.

The dome design was submitted by Kevin F. “Kefrith” Smith. His website may be found here:

The Miller Brothers and Scarab designs were submitted by Neil Darbyshire. His website may be found here:

The pins and buttons are now available for pre-orders in our registration system. If you have already registered, you can log in to your account and add these items to your cart for purchase. We will have a limited number of both sets available at the swag table at Mysterium.

Social Buttons

Speaking of buttons! We will have social buttons available for attendees, staff, and guests again this year!

Social Buttons

These darling little buttons measure 1.25” and the purpose of these is pretty straightforward. Wearing a green “yes” button implies that you are comfortable with people approaching you and engaging in conversation. A yellow “ask” button implies that you would prefer people to ask before engaging in conversation. And a red “no” button implies simply that you would like some space and to be left alone.

These buttons will be available at the registration desk at no cost. Just come up, snag one, and feel free to wear it on your badge, lanyard, or shirt. These are completely optional, just a nice easy way to communicate comfort level.

We do ask that everyone please be respectful with these. We also ask that the buttons be returned at the end of Mysterium so that we can sanitize and use them again next year. 

Stay warm, folks! We’ve got more announcements coming soon!

Mid-February News

Shorah everyone!
We have a couple of quick things we want to share with you.

Writing and Art Table Submissions

We’re thrilled to announce the return of the Table and submissions are now open! Spearheaded by our very own Annacat, the Table is an opportunity for folks to submit their fan work for display. Head over to the Submissions page for more information!

January Creative Prompt Winner

Covid-19 Updated Policy

We’ve modified the wording a bit to clarify what to expect during the Cyan visit on Saturday. The policy now states:

Importantly, a modified policy will be in effect for the Cyan visit on Saturday. We cannot guarantee that special guests and Cyan staff will be masked or vaccinated. We’re looking into the feasibility of streaming content from the Cyan visit for anyone who cannot attend. If you have questions about Cyan’s covid policy, please feel free to reach out to Jeff Lanctot at

Please note that Mysterium’s Covid-19 policy remains unchanged. Please feel free to reach out to us if you have any questions!

That’s all for now. We’ve got more goodies to announce soon!
