Immerse yourself more in your games! Spend less time doing maths and thinking about complex action economies and more time being your character.

CD10 is 80's action meets Blade Runner. A narratively leaning system where your character's history and personality matters.

With CD10, you can create gripping narratives, use character's personalities, histories and dreams as mechanics. You can allow players the power to shape their own destiny and truly become their characters.


CD10 is rapidly approaching 1.0 release! While we're doing the final touchups, things around here are going to be a bit chaotic. So bear with us for a few weeks while we get things in order!


  • Narrative focus
  • No base attributes or levels
  • Skill-based, horizontal progression
  • No hitpoints, but debilitating injuries
  • High lethality
  • Hero point system protects protagonists

Health and life

June was a good month for productivity. Both at work and at home. Mediciation is starting to really stabilize and while I'm still stressed and overworked, it's far more manageable at the moment than it's been in years. We've also just gone through the initial "stress-phase" of the investigation, so work pace is starting to settle a bit.

This has given me more opportunity work on my worlds and start to clean things up for the pending CD10 release.


The "todo list" for CD10 just keeps growing. There's a lot to do, but at the same time, progress is really great now. Many of the rules have really been polished. The Foundry system module is starting to approach something that may actually warrant release. I have a few more things to sort out before I really get to release, but it's closer than ever.

That nagging feeling I talked about in last month's update turned out to be true. Not only have I reinstated the Excess system for lethality, but I also reverted the +4 change for rolling 9's. My player-base and testers made it clear to me that while it can occasionally hilariously derail things, it provides a very necessary humorous element and there are usually tools to get around a catastrophe, even with stupidly exploding rolls.

For the more sane Keepers out there, I added a rule that 9's exploding may be capped at one reroll to curb the insanity that is 3-4 nines in a row. This rule is optional.


Second edition is shaping up very, very well and it's pretty much ready for initial playtests. Everything is in place for creating characters and starting to play. The conflicts system is what I'm most worried about, but without putting it through its paces I can't tell if it'll work at all. Session Zero with the playtesters are kicking off in about 11 days. Excitement!


Good progress has been made on the CD10 module and while it hasn't been released yet, the 0.5 update is looking really solid. Right now there's a lot of legacy crap in the code and I'm worried that a migration script really isn't going to be enough to clean up all the old fluff. I might actually just bite the bullet and release a non-migrated update and just accept that if there's someone out there updating their system mid-campaign, they'll have to suit themselves.

Like yes, that's on me. I was inexperienced and knew very little about Foundry development when I started and that technical debt has been building up over time and is really standing in the way of a functional system. We'll see. If I can find a clean way to do it, I'll migrate, but I very much doubt it atm.


I'm mostly working on a primer for my players in Cinders of the Cataclysm, but I'm also plodding away at Dark Shadow's history now that Chronicles is finally released. I'm enjoying worldbuilding again after a period of lull.

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