Celenia D10 RPG System

Created by

80's action meets Blade Runner. CD10 is a narratively focused system where your character's history and personality matters! Puts a high focus on verisimilitude over hard-coded realism.


The Celenia D10 Role-playing System [CD10] is a narratively focused, lightweight system designed to support heavy narratives and keeping the player engrossed in the moment.

CD10 keeps mechanics out of the way and is quick to work with. It is designed to work best with narrative and semi-realistic, high lethality stories where the players get to play the everyday hero in a rule-of-cool world.

CD10 consists of a core system (which you can use for free!) with several optional modules, called "Advanced", to support specific settings or functions. You can find them below.

CD10 Core is in beta and is considered feature complete. It is in testing in several different groups and is fully playable. No guides beyond the core rules are written just yet, so if you need help, please join the official Discord! The guides are being worked on, however.

CD10 Advanced is a collection of extention modules that expand on the core mechanics to suit specific settings or playstyles. CD10A makes CD10 more engaging on several areas, especially combat, and expands the core system with an ability system that allows for things like magical abilities, mutations, psionics, cybernetics etc.

CD10A is currently in development and is considered in alpha state. If you want to participate in the alpha test you can dive deep and try your feet with the full system by signing up to our Patreon at the "Keeper of the Tales" level or above!

May Announcement
Announcement: 25th May 2021

How goes that saying again? It never turns out the way you planned it?

In short, April and May did not at all turn out as planned. I've had two of the worst months in my life, with multiple health-care visits and an ambulance ride.

But, I did get a lot of work done and revamped and rewrote every single sheet and block for CD10 to better behave on mobile screens and have a coherent artstyle.

I don't know right now what's up for June, but considering CD10 is picking up a lot of speed, with more people using it every day, the Keeper and Adaptation guides are likely subjects for June. I need to get these guides written so people can start running games and adapt their settings to the system.

Stay tuned!

Celenia now has a unified place to access all the things with the url: www.celenia.se. It leads to the primary setting of Cinders of the Cataclysm, but the navbar can take you anywhere within the Celenia universe!
