Certified Guaranty Company® (CGC®) is excited to be accepting submissions at TerrifiCon at the Mohegan Sun Expo Center in Uncasville, Connecticut, on August 8-10, 2025.
TerrifiCon is Connecticut’s top comic‑con gathering since 2012. Over a lively three‑day weekend, fans dive into panels, autograph sessions, cosplay contests, gaming zones and an artist alley packed with comics creators — from legendary names to rising indie talents. Throw in standout media guests — from voice‑actors to film and TV stars — and collectible vendors galore, and you get a rollicking celebration of all things geek.
