Red Alert!

Romulan Commander Sela is on the loose, and she's coming for the prime timeline: prevent the Artemis II launch in 2026, and humanity never unites and reaches the stars. No warp drive. No Federation. Your mission: (you know the drill) protect the timeline and stop her at all costs.

Join us at Trekfest 41 in Riverside, Iowa (the future birthplace of Capt. Kirk and only 4 hours from St. Louis!) for a gamemaster-led team adventure. Choose your Trek crew, tackle hilarious challenges, laugh with fellow fans, and save the future by protecting the past.

All ages and experience levels welcome. Space is limited- claim your spot before Sela claims the timeline! We will be hosting 5 event time slots throughout Trekfest. Sign-up early to ensure your spot. 

 This is a new game format that includes the teamwork of a trivia table, the thoughtfulness of a great book discussion, and the creativity of a lite-RPG. Teams are competing to stop Commander Sela from rewriting the timeline, and the way they do it is through hilarious challenges and deep-cut Trek discussions (most underrated B characters, anyone?). Don't want to spoil it, but hope this helps. It's a really fun time with a unique immersive game - hope to see you there!
