Midevil MarsCon

MarsCon is a fan-run science fiction convention for all ages held every March (sometimes in late February) in the Twin Cities area. At MarsCon you’ll find panel discussions, parties, guest of honor presentations, music of many kinds, our art show, film/anime room, science room, dealers room, charity auction, and masquerade. The Dementia track is virtually a con in itself, and attracts a nation-wide audience.
