Hello! I'm absolutely stoked that you have shown interest in the Celenia D10 roleplaying system! CD10 is a commercial product in the making, but the entirety of the core rule set is free to use! If you want access to this advanced module, you can head over to patreon and sign up at the Gamemaster tier. That will give you access to all the advanced modules and the entire ruleset! Since you are interested, consider having a look at the Patreon Page and pledging your support! Not only will you actively help bring this game to the masses, but you will also get immediate access to what you want!
