Welcome to the LUMEN jam!

This jam is for making anything you want with the newly released LUMEN system. That could mean making a brand new game, or creating some new classes, rules, or supplements for existing LUMEN RPGs! Check out each other's submissions as they come in, you might find something you want to build with.

Here are some general rules and guidelines:

  • Create anything you want using the LUMEN system
  • Feel free to break the SRD as much as you want!
  • Whole new games and supplements of existing games are all welcome
  • I encourage you to put a price on your work, if you are comfortable doing so. If you do, I would also encourage you to use Community Copies as an option to help those in need
  • If you participate, tweet me @GilaRPGs and let me know! I want to see it, and share your excitement!
  • Any games or content that encourages hate or bigotry have no fucking place here. 
  • If we need more time, I'll extend the deadline!

If you do make something, all I ask is that you include the following text, and the logo for games "Illuminated by LUMEN" somewhere on your page. You can find a download of the logo on the LUMEN page!

"This game is Illuminated by LUMEN, based on the LUMEN RPG system designed by Spencer Campbell, Gila RPGs. This game is in no way affiliated with Spencer Campbell or Gila RPGs."
