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!
