A follow-up to our post about the recent proliferation of AI creations in our community content programs at @drivethrurpg.com and our efforts to combat it... 🧵

Out now! Pendragon: The Boy King is both an epic campaign spanning nearly twenty years of game play and an indispensable toolkit for running Pendragon in the early years of Arthur’s reign. #pendragon #ttrpg #rpg bit.ly/4zRCB8u

Roleplaying games are a way for humans to imagine and explore. We do not permit AI text in the Chaosium community content program, and sadly we're getting quite good at smelling it. To paraphrase HPL's description of the Necronomicon, AI text reeks with an unholy and unidentifiable stench.

It's the 8th anniversary of the passing Chaosium founder Greg Stafford and on Oct 21st we're launching a new edition of his masterwork The Great Pendragon Campaign. Here, for the foreword, Greg, depicted as a senior monk, passes the mantle of Pendragon to his chosen literary successor David Larkins.

After many years of having it on my bucket list, I finally started the Great Pendragon Campaign. @stillisgaming.bsky.social is GMing and we started our first session doing character creation, being knighted, and going on our first excursion. seannittner.com/the-great-pe...

Carl T. Ford was a chap of rare energy and enthusiasm. Writing for and distributing his Call of Cthulhu and Lovecraftian fanzine Dagon opened the way for so many more friendships. It’s marvelous to see RPG historian @shannonappelcline.bsky.social set down the history of Dagon Press.

Got to play me some timewithouttide.com yesterday and I love this game I LOVE THIS GAME

A criminal gang lying low after a heist gone wrong finds find the town of Innsmouth to be anything but safe...

For this study, I wanted to recreate Dawn's official portrait from the "Fear of Flying" adventure for Call of Cthulhu, something I've been wanting to do for a very long time now! I'm quite happy with the result

What RuneQuesters are saying about our new release Cocaine Jack-o-Bear...

New Zealand may be nuclear free, but it is not Cthulhu free…

Just when you thought it was safe to go back into the 1890s…

We invited authors of the old Monograph series to republish their work in the Miskatonic Repository at @drivethrurpg.com.

A screen at last, an excellent gazeteer of Arthur's kingdom, and splendid book of resources... the Pendragon Gamemaster Screen Pack is here! www.chaosium.com/blogout-now-...

"After all, what is a shadow if there is no light", it spoke softly. Just noticed there has been traffic to this account, thank you all! I might not be too active here, as I'm quite done with social media over all, but I'm grateful nonetheless. I'm most active on instagram (pauhami there as well).🌼

Melbourne folks! You could play here!

My niece came to my house today and painted her first ever miniature. I don't think I have ever seen anyone else being as naturally precise and talented on their first go. She chose a lovely mini from @badsquiddogames.bsky.social for her first one.
