New to DemiCon?
We are a not for profit, 100 percent fan run convention that is put on by the Des Moines Science Fiction & Fantasy Society. We are very different (much better!) than large, corporate conventions. To get started, we recommend reading our FAQ for a quick overview. Then explore the rest of the website at your leisure!
What is the theme for DemiCon 36?
Our theme this year is FANtasy — a celebration of all the fans that make fan run conventions like ours a success.
Attendees might go on a fan-centric fantasy adventure, attend a fan painting workshop, or even encounter some fan dancers.
You are sure to have a FANtastic time!
