ConClave was an annual, weekend-long science fiction convention in southeastern/central Michigan, which drew approximately 600 people. ConClave attendees shared an interest in science, science fiction, fantasy, and related genres. The ConClave convention was held each year from 1976 to 2016, with the exception of 2012. In 2017, the convention was rebranded as The Continuum.

While remaining true to its literary roots, ConClave celebrated fantasy and science fiction in all its myriad forms, including art, music, theatrical performance, and film. Displays included animation, television, fantasy role-play, and renaissance reenactment. Participants included gaming enthusiasts, writers of fiction, pilots of spaceships, Rennies, and Furries. ConClave was an all-ages event.

Attractions

ConClave had several established traditional attractions, most notably a well-supplied Convention Hospitality Suite, a Saturday Night Costume Ball, a merchandise area, several tracks of programming of interest to its membership, and a loyal following of staff and panel participants. Programming tracks include writing/literature, SF/Fantasy, Science/Space, Music, and Gaming.

Recent additions to Conclave retinue have been a video room that screens rare anime and fan-created SF/Fantasy shorts, astronomical observing, and prep workshops for those interested in participating in NaNoWriMo.
