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.

#DnD players: somewhere against yet another goblin horde, the thought popped into your head and now? It lingers there, tempting you every time you touch your dice. The spark is gone. Your heart is wandering.

"I wonder what #indie #ttrpgs are like?"

We get it. You're try-curious. Go on; be bad.

The Wizard dons a fake plastic mustache to regain some semblance of dignity and heads out into the murky morning mist. The Journey to get his mustache back begins the way most of life's journeys do, with a single step, toward Pierce Brosnan.

Had a great #Arrhenius game last night. The crew is exploring ancient transit tube systems under the city of Lō-Dō. They ran into the decaying remains of a train car whose holographic Conductor had been “living” amongst the bioluminescent mushrooms of the flooded line for thousands of years.

If I was a paleontologist, geologist, or the like, I get the sense that my mortal enemy would be the Ice Age franchise movies.

Is it tacky to plug your own game? 😬 I released my first game, #Arrhenius, in May.

The opening of a new #TTRPG adventure I’m writing for #Arrhenius. #indiegames #rpg

Arrhenius @arrhenius.bsky.social · 18d

Flames engulf the candy apple red Veygama ekamaran as it screams through the atmosphere. In seconds, the small cruiser punches a hole through the clouds revealing a frozen wasteland of endless ice. Call it what you want: Ân, Soliby, Terrewan, Colonial Prime.

This is Earth. (1/🧵)

Each of the three montdenierium feet, still warm from the atmospheric chaos of reentry, squeak and steam as they make contact with the glacial ice. The ship’s bulk settles while inside, the first cask lid opens. (7/7)

disables the casks’ safety locks once they reach nominal levels. The ekamaran’s landing foils unfold gracefully like the extensions of a skilled dancer. (6/🧵)

The shock absorbing interior cushioning deflates, easing the pressure on the life support system tubing. Slowly, each cask’s inhabitant progresses from deep hibernation to sleep to twilight to wakefulness. Their heart rate and brain scan data—)constantly monitored through Sentinet connections—(5/🧵)

There’s a beep as the Veygama makes a selection and suddenly banks left, heading towards a mountainous range with a collar of evergreens.

Inside the ship’s small living quarters, a cascade of clicks and notifications flash across screens on the five occupied sensory deprivation casks. (4/🧵)

Exterior visual sensors display a real-time view of the frozen planet as it speeds past underneath. Everything is either ice or ruined by ice. Lines of analytical text propagate across the display as distant range bio-sensors scan a five klick radius. (3/🧵)

The ship screams through the sky leaving a sonic boom in its wake. Its exterior skin creaks and cools as it slips through the subzero atmosphere. Soon snow begins to accumulate on its hull. Inside the ship, a wall-wide display screen flickers to life. (2/🧵)
