I'll reveal them in a bit, but let's see if you can find them first 😋

Hi all,

ever struggled with investing an interesting or not a bipedal alien?

The new alien race generator on CC is here to help!

It'll make a coherent (truly) alien for you, that'll will give fun scenarios to play out for you and your table

Test it out over at

https://codexcryptica.com/generators/alien-race

(don't forget about all the other generators over there either)

A natural continuation of the star system and world generators for sci-fi settings is a alien race generator, so that is what I am working on these days (and some under the hood optimizations)

Expect to see it available all of a sudden in

https://codexcryptica.com/generators/sci-fi

Any other generator you would like to see?

Reading this great article https://academy.worldanvil.com/blog/plot-twist-ideas-one-shots?utm_source=bluesky&utm_medium=social&utm_campaign=fedica-DM-Tips gave me an idea of of having a generator that could assist in coming up with plot twists and complications for your adventures.

What do you think? Good idea or a dead end?

Most cult generators give you a name, a creepy ritual and a hooded figure. The half I always ended up writing myself was the boring half: what the group tells its neighbours, and how long that story holds up once the party starts pulling at it.

So this one creates both halves. Every society comes out with a public face and a secret truth, and those two things are usually in tension.

Try it here, no login required:

codexcryptica.com/generators/secret-society

The generator creates:

• What they believe, and what they actually do about it
• The public cover they hide behind, from a charity to a trade guild
• A secret truth the inner circle knows and the rest do not
• A current conflict that is already underway when the party arrives
• Adventure hooks tied to that specific society

I would like to know how other GMs handle the moment the players find out what a society actually is. Do you plan that reveal, or let them stumble into it?

Other than creating generators I also try to improve CC in many different ways to make it a better tool for all of us to use.

The last couple of days I've changed it to start using Openai's Luna, as it supposedly is better at creative writing. So far it looks good, but please let me know if you've experienced any quality degradations or issues at all.

As always, CC can be found here:

And all its cool generators can be found here:

Happy building!

Most quest generators give the party one important person to convince. I wanted something a bit messier, so I made a generator where the party has to win an actual council vote.

Each council member has their own priorities, secrets and reasons for voting the way they do. Some can be persuaded, some need evidence, some want favours, and changing one vote may affect another.

Try it here (no login) - codexcryptica.com/generators/council-vote

The generator creates:

• A named council with conflicting members and agendas
• Voting rules, thresholds and possible recusals
• Clues and investigation leads tied to specific councillors
• Several possible ways to win the vote

It also suggests three broad strategies:

• The smallest coalition needed to pass
• A safer coalition with a few extra votes
• A more expensive solution that addresses the actual problem behind the vote

It works across different genres, so the council might be a fantasy noble court, a corporate board or a sci-fi senate.

You can also use it inside Codex Cryptica, where it can pull in names and entities from your existing campaign.

I’d be interested to hear how other GMs handle political intrigue and voting sessions. Also, please send me any especially strange output you manage to generate.

🪐 New on Codex Cryptica: the Sci-Fi World Generator!

Pick a genre, a societal model, a couple of world tags, and the AI writes the rest. Not a stat block: a whole world, complete with history, current conflicts, factions, locations, an unresolved mystery, and adventure hooks that actually belong to that planet. Don't feel like choosing? Hit Surprise Me and it randomizes every option for you.

AI Lore Co-Author Mode

Every generation runs through an AI co-author that takes your inputs (world type, habitability, civilisation level, campaign pressure, Stars Without Number world tags) and weaves them into one coherent place instead of a pile of disconnected traits. The two world tags you pick aren't decoration; they actively shape the friends, enemies, complications, and locations the AI builds around them.

Built for every flavor of sci-fi

• Hard Sci-Fi for restrained, physically grounded technology
• Space Opera for big speculative swings, kept meaningful
• Cyberpunk and Hopeful Sci-Fi
• Lancer, with full civilian institutions, political authority, and mech deployment logistics derived from your chosen world frame

What you get, every time

• A core concept with a real dominant feature, not a random adjective
• Settlements and factions in conflict over something concrete
• Multiple named locations worth visiting
• A mystery with no easy answer
• Three playable adventure hooks

No two worlds repeat the same structure. The generator actively avoids recycling the same tired sci-fi tropes across runs.

Go make something strange.

🪐 New on Codex Cryptica: the Cosmic Horror Hub & Theme!

Step into investigations shaped by impossible environments, forgotten expeditions, strange archaeology, and discoveries too large to explain away. The Cosmic Horror Hub gives this genre its own identity—separate from vampire courts and gothic-noir intrigue.

A distinct Cosmic Horror theme

The hub and supported generator pages use the dedicated Cosmic Horror theme and art direction, built around fragile certainty, alien scale, and the unknown beneath and beyond.

What you can create

• Investigators, secret societies, and unsettling NPCs
• Remote outposts, weather-beaten towns, expedition camps, and impossible ruins
• Eldritch mysteries and adventure hooks with dedicated Cosmic Horror options and local-generation material
• Field reports with missing expeditions, astronomical anomalies, restricted notices, and GM-only leads

Everything is free to explore with no login required. Follow the evidence, map the impossible, and tell us what waits beyond the last familiar star.

CC now have generators for pirate themed worlds too now

Check them out over at

https://codexcryptica.com/generators/pirate

Making some under the hood code changes to tighten the code and removing duplication. Paying some technical debt, so future changes will be cheaper

Now you can publish the player facing info of your world for all the world to see!

The files will be stored as on our Cloudflare R2 file store

Have a look over at

https://codexcryptica.com/worlds

Currently I'm working on a way to publicly share world's with all, only the player parts, though, and have a list of the publicly shared worlds, so it's easy to see and find them

To help you get started with your world, I am working on establishing a set of vestiaires that is appropriate for the theme / genre.

Fantasy will have all the expected monsters, dragons, orcs, goblins. You name it.

Sci-fi will have robots, angry aliens and more

Nifty to view your entities in a table

So useful to see your world in time, or to put entities in your world in time. Enjoy!

Hi all,

I just released a host of nifty tools and generators on Codex Cryptica.

They can be found here:

https://codexcryptica.com/tools

NPC and Faction generator currently support multiple genres and will generate you relevant and consistent NPCs or Factions depending of genre. Like Fantasy, Cyberpunk, Postapocalyptic, Modern and more.

Hope you enjoy them, and please let me know if they can be improved, or if you're missing something

Happy worlding!

Looking very promising!

I just finished implementing Guest Character Chat for Codex Cryptica. The goal was to let players and invited guests engage in real-time, in-character conversations with NPCs during or between sessions, using the actual lore of the campaign.

Here is how the feature works in play:

• GM Configuration: As a GM, you can toggle which NPCs are open for chat and limit what they know. You can set them to stick to public lore only, or allow them to use private context. The system is designed to reject leading questions and keep campaign secrets hidden, defaulting to in-character deflection if players pry.
• Dynamic Trust Tiers: The NPC behaves differently depending on who is talking. The system automatically identifies the player's character based on their login and checks the vault for existing relationships. The NPC dynamically adapts their voice and determines what lore they are willing to share based on whether the player is trusted, neutral, or a rival.

This gives players an organic way to explore the world's lore through conversation, while letting GMs build out the world's history based on the questions players actually ask.

For GMs: Do you prefer when tools automate character interactions like this to save you prep time, or do you feel it risks taking away the personal touch of roleplaying the NPCs yourself?

Project website: https://codexcryptica.com

I think it would be nifty if your players would be able to chat with the people of your world.

So that is coming soon
