Miskatonic Respository Con 2026

The Call of Cthulhu Miskatonic Repository Convention is a three-day virtual convention celebrating Chaosium’s online collection of user-made content. All content is Call of Cthulhu 7e, and is either currently published, or being prepared for publishing, on the Miskatonic Repository.

We're so excited (and humbled) to return for our seventh year with more games, more panels, new special guests, and more community support!!! Best of all? It's all FREE.

The Miskatonic Repository is an online platform where anyone can publish and sell their playable content for the Call of Cthulhu 7th Edition roleplaying game by Chaosium. You can see more here!

For Players: Player signups will be available September 25th, 2026.

For Keepers: We welcome you to submit playable content that is either published, or intended to be published on the Miskatonic Repository, starting September 4th, 2026.. Playtests welcome! While each time block is 4 hours long, shorter games are welcome! While the form is only set to allow for a 4 hour duration, you are allowed shorter games. Please explicitly and clearly communicate game times in EDT in the description of the game to allow MRCon to run as smoothly as possible.

Please use the schedule system on the right-hand side of this page.

KEEPERS MUST SUBMIT EVENTS WITHIN THE ASSIGNED TIME BLOCKS (see bottom of page and check your time zone). Events submitted outside of these blocks will be sent back for modification.

Game submissions open on September 4th, 2026

All game systems should use the Call of Cthulhu 7e rules. Please schedule games in the assigned time blocks, as we need to keep online play spaces going and organized.

We are an international convention, but due to organizational capacity, we are based in United States Eastern Daylight Time (EDT) (UTC−04:00). If it is 16:00 Pacific, then it is 18:00 CDT, and 19:00 EDT as an example. Please convert any times into your local time here.

Discord will be used as the main engine for communication and for playing games. This is so we can organize the con and keep Keepers on time so the next group can use their respective slots. You can join via this link HERE, and please check in regularly.

Everyone that attends agrees to the Code of Conduct found HERE. Miskatonic Repository Convention is for attendees +18+.

Panels, Panels, and more Panels

We have expanded the schedule to allow for more downtime between games and panels. We are still organizing panels and will give out more information as the convention approaches.
