You only have a short time until we will have to shut off pre-registration, so it’s best to get your tickets now. Pre-reg will be open all of this week and we will be announcing the date that we close it after this Friday. They are more expensive if you buy them at the door and with an event schedule and guest list this amazing, it’s truly going to be a once in a lifetime event this year.



Sept 1 at midnight = last chance to get con t-shirts

Sept 1 (tomorrow) at midnight is the LAST CHANCE to order your regular and VIP con T-Shirts for Intervention: Sci Fi, Fantasy, & Future Media, designed by Oni Hartstein. Which is me. 3rd person me.

Not only are these the first things that I designed after the doctors restored my vision, but they are some of the best designs we’ve ever had and your purchase helps us make the con more awesome.

If you already registered (or are staff) you can upgrade by simply registering but only ordering a shirt. If you need help, just email



Thank you everyoen who has bought VIP levels and registered so far. We couldn’t do this without you and you mean so much to us. :)
