How do I register for this year’s Mysterium?

When registration is open, you can pre-register for Mysterium on our registration page. Registration will close about a month before the convention date. If you are unable to register online or you miss the deadline, you may register at the door when you arrive. Please note that if you do not register online, we cannot guarantee that you will receive a swag bag or convention book, as our orders for these materials are based on pre-registration numbers.
