Follow the idea.All the way down.

The idea is a contract with the reader

A science fiction reader will accept almost anything once. A ship that folds space, a city that never sleeps because nobody needs to, a drug that lets you remember other people’s lives. What they won’t accept is the idea quietly changing when the plot needs it to. If the fold drive needs a week to charge in act one, it can’t be ready in an hour for the climax unless the story pays for that.

So the hard part of the genre is rarely the invention. It is the bookkeeping that follows it: what the technology costs, who has it, what it has already broken in the world, and what the characters know about it at each point. That is the part Authrot is built to carry, so your attention stays on the people the idea is happening to.

A useful habit from the genre’s workshops: for every invention, write down three consequences nobody in the story asked for. Cheap fusion means no more coal towns. Memory trading means a black market in childhoods. Those second-order effects are what make a world feel lived in, and they are exactly the facts that get forgotten by the middle of the draft, which is why it pays to keep them on the same entry as the invention itself.

Write the rules down, then let the chapters be checked

The science fiction starter in Foundations opens with one rule to fill: the big idea, the one technology or change the story turns on, what it makes possible and what it breaks. It becomes a lore entry in the bible, and you can add more beside it: how the drive works, how the AI was trained, what the treaty forbids. Anchor the facts that must never move.

When a chapter is read, Authrot tracks what happens, who appears and where things stand as the chapter ends, each tied to the words that established it. A line that contradicts an earlier fact or an anchor is flagged against the fact it breaks, and you can ask for a suggested fix or leave it as it is. Drift checks also tell you when a chapter strays from its arc or its anchors.

• Anchored facts the story must never contradict
• Facts that change over time, like a ship’s damage or a planet’s government
• Kinds of your own: ships, species, technologies, stations
• Contradictions shown beside the earlier fact they break

Show the world through detail, not briefings

The starter’s style note says it plainly: let the reader infer the world from detail rather than briefings. The trouble with that advice is that details scatter. The name of the station’s currency turns up once in chapter two, the slang for off-worlders in chapter seven, and by chapter twenty you are searching your own draft for them.

Once a chapter is read, every mention lands in the bible in reading order, with four kinds of reference: where something is named, referred to, relied on, or shapes a scene without being mentioned. Close-spelling search finds the station you half remember, and project search finds chapters, notes and entries at once. Type [[ to link a name by hand, with no AI involved.

Space opera casts and alien names

Big science fiction is often big in cast as well: bridge crews, rival houses, a dozen planets with their own politics. Screen time shows who is present in every chapter and whose point of view it is told from, and characters who have gone quiet too long are flagged as due back, which matters when a minor engineer is meant to save the day in book two.

Give each species or culture a naming style and the name dice roll names that fit it, learning from the examples you give. The cast check warns when two names start alike or look alike, the usual cause of a reader confusing two pilots, and when a name is one every AI reaches for.

Importance is worked out from the text: main, supporting, minor and once. In a space opera that matters more than it sounds, because the bible browser can then show you only the main players when you are plotting, or every walk-on crew member when you are checking who was on the bridge during the attack. You can pin an entry’s importance if the text undersells it.

When the idea changes halfway through

Science fiction drafts often discover their real idea late. You start writing about a generation ship and realise in chapter fifteen that the story is about who controls the ship’s memory. Changing a core rule mid-draft is normal, but every earlier chapter that relied on the old rule now needs finding.

Update the anchored fact and have the chapters read again, and the contradictions show up in one list of checks, each beside the earlier fact it breaks. Renaming a technology or a faction is one step across the whole text, with a preview and undo. And because every version of your text is kept, along with every change to the bible, nothing you rewrite is lost if the first idea turns out to be right after all.

Near-future, cyberpunk or hard SF

The science fiction starter offers space opera, near-future, cyberpunk, hard science fiction and post-apocalyptic as subgenres, and fills a close-third, past-tense viewpoint with a curious, tense tone as a starting point. Every field is yours to change, and anchoring one keeps the Co-writer from redrafting it.

Hard SF writers often want to check their own working rather than have anything written for them. If that is you, AI blackout turns the AI off for the project: no model reads a word and every AI control leaves the screen. The bible, anchors, linking by hand and the story map still work.
