Mysterium 2021 will be held online during the weekend of July 17.

We have not determined a schedule yet, but we will update this page when we have more information.

The Westin Alexandria Old Town in Alexandria, VA was intended to be our official hotel for the in-person convention. While there will be no official events held at the hotel, they are keeping our room block open and you may book rooms at the Mysterium rate if you wish using this link.
