I downloaded these modules to use them in conjunction with a sandbox called Star Machine of the Fading Waves (which you can find here on itch, published by Jlaakso) in my OSR roleplaying game campaign. It's truly amazing, and thank you for writing it!

Here's the link to the jam, in case you'd like to participate:
