A planet with no ground, a wind with an expiration date, and a weekly loop between me, Claude, and a room full of strangers.
The only land is mountaintops.
Every peak on the planet rises out of a cloud layer that kills you in roughly two minutes, so the peaks are islands, the cloud is the sea, and nobody goes down. Nobody has ever gone down. (How far up are they? Hold that thought.)
The people who live up there fly, on craft called shifts: a delta wing of leaf membrane stretched over bamboo, a flat raft deck slung underneath, the pilot hanging off the frame like laundry in a stiff breeze. They write on flags. A full-size flag is an event, a half-size copy is the record of the event, a quarter-size copy is the record of the record, and somewhere in eight hundred years of shrinking their own history down, it quietly became writing. Their music is built from sonic signatures, one per person, so every song is a roll call of who showed up. And they're all vegetarian, which sounds like a lifestyle choice until you learn that in their first three hundred years they hunted every bird on the planet to extinction.
The diet is what's left. A monument to something they did.
The wind that carries all of it (flight, trade, food, pollination, every load-bearing system they have) is a thousand-year atmospheric-circulation line item. Somebody costed a millennium of weather, signed the package, and moved on to the next one. The budget is nearly spent.
That's Skytribe. The story is the day the wind stops.
For a long time, the wind had stopped on the project, too.
Becalmed
I've been carrying this world around for years, and I have the paperwork to prove it: a Google Doc called Skytribe 3.5, which raises questions about versions one through 3.4 that I'm not prepared to answer; six separate files named skytribe-primer.md; five named skytribe-glossary.md; one called Skytribe Primer – Delete, which I have not deleted; and a six-notebook Evernote stack I never opened.
The files weren't the problem. I needed to build this world in my head, the whole thing, and I never had a way to build what I wanted. I'm not claiming to be a novelist. I'm a big-picture guy who's bad at the part where you remember what you decided on a Tuesday, and that part, it turns out, is the entire job. A world isn't an idea. It's ten thousand small decisions that contradict each other until somebody writes them down and holds them still. Mine never held still.
Lift
What finally held it still was Claude, and the least literary room I have.
My car.
I should say: I fucking love talking to my car. I've always wanted to do this.
Mostly I ramble and Claude sorts, and every so often it turns around and quizzes me. How long can a pilot stay aloft? Did they copy the wing from birds? What happens at a funeral when there's no ground to bury anyone in?
About two days of snacks. No, from dragonflies at the oases; the birds were already gone. And nothing. A body below the cloud line is unreachable forever, so somebody builds a cairn with nobody in it.
The big pieces came out of those drives. The ships used to be bamboo hulls with leaf-shaped sails, which is lovely right up until someone asks how, exactly, you launch a boat off a mountain. The boat did not survive the question. Now they're shifts. The birds went extinct on a drive, and the whole planet went vegetarian in the same conversation. And on some stretch of road we worked out that the wind carries pollen, not just pilots. When it stops, the groves stop fruiting, and a travel problem becomes an everything problem.
Claude remembers what I said three drives ago and flags it when a new idea breaks an old one, which is exactly the thing I can't do. Whatever we land on goes into Notion: a Canon Bible, a Characters database, a Glyphs & Flags database.
In the two weeks after I set it up, the Canon Bible went from five short sections to real rules for pollination, oases, flag archives, parties, food, and the empty far side of the planet. The Characters database went from nobody to four people, two of whom are dead. After years of dead air, that's a gale.
The part where it has to meet people
Canon on its own is a diary, though. It can't tell you whether any of this works on people who aren't you. So the rest of the engine is a loop.
I talk it through in the car. We decide canon together. It lands in Notion. From there Claude drafts one Reddit post a week, rotating shapes (a journal page, a single flag, an open question) so it doesn't turn into me yelling LORE at strangers every Tuesday. I post it by hand, because Reddit doesn't want bots posting promo, and fair enough. When replies come in I carry them back, and we sort them into what landed, what confused people, and what got asked twice. The confused pile is where the next drive starts.
It isn't smooth. The weekly nudge was supposed to ride along in my nightly brief and never got wired in, so the reminder system is me remembering. (See: Tuesdays, above.) Voice transcription has strong opinions about proper nouns, and none of them are the ones I invented. The Glyphs & Flags database has zero entries. A civilization that talks in flags, a database built to hold them, and I have not settled one. The car is great for rules and terrible for pictures. You cannot design a flag at seventy miles an hour. (Please don't.) And since Claude can't read Reddit, I'm the courier: the least reliable component of a system I designed.
A scary story, told badly, with pictures
In the first Skytribe story, a man from somewhere else lands with thirty-six days and a warning: the wind is going to stop. The warning goes nowhere. Not because it's impossible. Because the people there already have becalming stories, and they tell them to children. So he's telling a familiar story, badly, in an accent, with pictures.
I posted Skytribe to r/worldbuilding in September. Hitting Post felt weirdly fine. The familiar-story part came in the replies: two people let me know that mountaintops over poison cloud had been done, by Larry Niven, around 1968, and a third found a video game with a similar view. Fair. Execution, one of them said, matters more than originality. Noted.
What the room said
The best reply went after one number. I'd written that everything below about four thousand meters sat under the cloud, and a commenter asked the obvious questions. Who measured it? Up from what? "By specifying elevation," they wrote, "you are courting questions that do not contribute to your story."
They were right. The cloud line is their sea level, and nobody on that planet has ever been below it to measure anything. I took the note into the car, we dropped the number for good, and you may have noticed it isn't at the top of this piece either.
Most recently, someone asked the question I should have answered first. So what's the origin story? A slow build-up of gas? A volcano? "Are they shipwrecked space explorers stuck on an alien world?
The answer has been sitting in the Canon Bible for weeks. It just wasn't in the post. That's the loop doing its job: the confused pile is the next post.
Back in the car
In the story, the wind stops and a world has to learn to fly without it. The project went the other way. It sat becalmed for years, and what got it moving wasn't a better notebook. It was a conversation, a place to put what we decided, and a room of strangers willing to tell me which parts read as a world and which read as a guy with diagrams.
The wind's up, for now. I get back in the car.
P.S. The Glyphs & Flags database is still at zero. A good candidate for the first entry: the flag a pilot lays out on the day they stop flying for good. If you have opinions about what "grounded, and that's fine" looks like in cloth, the thread's on r/worldbuilding. Bring them. I'll be driving
