From publisher blurb: This one-page supplement features a system that lets you create an enemy to face in your OSR games with just one roll. It also includes a mission generator so you can keep things interesting for the party. Even though it was designed for White Star, the system is absolutely useful for any genre or OSR game rules. The system is featured in our OSR Sci-Fi GM Screen, but since we're so pleased with how it works, we're giving you this part for free. If you like it, there's lots more content available in the full screen.
