New York’s hottest #ttrpg is Arrhenius. IT. HAS. EVERYTHING.
✅Exploding dice
✅Psychotropic eel poop
✅Feral AI
✅Human snowpants
(What’s “human snowpants”?)
It’s that thing of when a robot decides it isn’t human enough so it skins you and wears it out on the glaciers.

The artwork for Ex Partum was done by my mother, Ellen Burnett. She is a truly amazing artist, whose artwork leaves me wanting to simultaneously cry and sigh in satisfaction.

![R. H. Bing (October 20, 1914 – April 28, 1986)[1] was an American mathematician who worked mainly in the areas of geometric topology and continuum theory.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:cyyd366g3hrxp5rynixm2mm3/bafkreid62wy3dekb2kzbisjfdlimlb35j4rlgew5iof7vi32byfszmg26a@jpeg)
![Bing's father was named Rupert Henry, but Bing's mother thought that "Rupert Henry" was too British for Texas. Thus she compromised by abbreviating it to R. H.[5] Consequently, R. H. does not stand for a first or middle name.
When Bing was applying for a visa, he was requested not to use initials. He explained that his name was really "R-only H-only Bing", and ended up receiving a visa made out to "Ronly Honly Bing".](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:cyyd366g3hrxp5rynixm2mm3/bafkreigmfj53q4uy33spga2bxdkllqm3ag5sffovg5g7ddmu3vqzkb6k24@jpeg)

Well... except for the feral AGI in the world-building. That's a thing.

IT’S HAPPENING.
I’ve started commissioning new art for the first #Arrhenius expansion. Known as “Fahjē’s Guide to Gear,” it’s a system for dungeontellers to use in order to find all the special garba—I mean, all the special treasures that are scattered all over the ruined planet.
