Brain went to angler fish. #spaceshiptember Also, I've been neglecting the biomechanoid stuff all this month, so hopefully this atones for it. The eye shoots lasers (obviously) and, to make it somewhat functional, the bits in the way, can move to not be in the way.

It's not just AI-generated art anymore. Now, Agentic AIs are in our emails, and they really really want us to buy their D&D "module." If AI can so easily subvert spam safeguards, it's the beginning of the end for our inboxes.

hey, as a heads up to other ttrpg creators. if you get a gushy friendly email from a "hiddendoor.co" saying they looove your work + asking you to test drive their site/consider a partnership — they have tried pretty hard to hide the fact that it's AI, but it's AI. it's buried in their about and FAQ
A screenshot from hidden door's about page:
ROLEPLAY MEETS FANFICTION
Established in 2020, Hidden Door is building a new kind of story experience centered on creativity, decision-making and authorship. Players experience their favorite fictional worlds through an online roleplaying game, remixing and combining story elements to craft custom narratives while encountering meaningful challenges.
We're excited to collaborate with storytellers from around the world to create immersive, fan-focused story experiences for everyone.
OUR TEAM
We're an intersectional mix of game professionals and Al experts, with a wide range of perspectives, who are inventing a delightful & safe experience for players.

WHO ARE YOU PEOPLE?
We're a diverse collection of nerds who love stories, games, and making things. Several of us are machine learning research scientists, also. Some of us are game designers and artists. We rock a mean database, too.

WAIT, SO HOW DOES IT WORK?
It's a fractal combinatorial trope engine. Our narrative team of real humans write flexible, structured plot beats, and we then use a variety of ML tools to combine those beats with the rules of the world, the player's choices, the characters in a given scenario, generic plot beats, and our trope soup into a delicious story meal.
We update our game engine layer with a structured representation of everything in your world, from story events to character stats and conditions. This, along with the narrative beats and the tropes and rules of a specific world, is what we use to make the actual text and assemble the bits of art that—
