The Master and the Unity

Do come in, and mind the dust — this record begins, improbably, with plumbing. In late 2161 the water chip in Vault 13 failed, and took with it the vault's comfortable arithmetic: one hundred and fifty days of drinkable water behind a door that had never once opened. The overseer chose a single resident, issued a canteen and a flag pin, and sent them up into daylight no one below had ever seen.

What the Vault Dweller found was not the nothing the brochures had promised. Shady Sands stood behind adobe walls, raising crops and a remarkable young woman named Tandi. Junktown had built law out of scrap. The Hub moved water, caravans, and money, in that order. Necropolis kept its dead walking and its opinions to itself. New California was alive — and in every town, the same rumor in the same lowered voice: something in the west was gathering an army.

The vault sent one resident out for water, sir. This record is everything else that was found.

The army had a source, and the source had been a man. In 2102 an expedition out of the Hub went hunting the origin of the mutant animals on the caravan routes and found Mariposa Military Base, where the Old World had moved its Forced Evolutionary Virus from the laboratories of West Tek. The expedition's leader was Richard Grey — Moreau, in the older files. A robotic crane arm knocked him into an open vat of the virus. His companion Harold woke in the desert, already changing. Grey crawled out over a span of days, dissolving and reknitting.

What finished crawling was no longer Richard Grey. It grew into the vats, then into the base's computers, then into every mind it drew under, and it spoke — when it spoke — in several voices at once. In time it began lowering living people into the virus, a procedure its followers called dipping, to manufacture a hardier kind of survivor. They called it the Master. The record has no better name on file.

Now the part the archive asks you to sit down for: the Master was persuasive. His argument ran so — the Great War had proven, at the price of the world, that a divided humanity cannot keep itself alive. As long as there are differences, people will tear themselves apart over them; very well, end the differences. The virus offered one species, strong, long-lived, proof against radiation, and the Unity would fold every fractious tribe into it: by sermon where possible, by the vats where not. Above ground he raised the Cathedral and filled it with soft-voiced missionaries, the Children; beneath it, he waited. I have read a great many manifestos, sir. His is the only one in my files that begins from a true premise.

The refutation was not moral but clinical. The dipped were sterile. Every mutant the vats produced was a conversion, and no conversion can ever be a birth; the Unity could grow only by unmaking people, and when the people ran out, it would end. The Master's perfect future had no children in it. An argument, however courteous, does not survive its own arithmetic.

The ending is canonized by the sequel record, so I may file it as fact: the Vault Dweller destroyed both heads of the Unity — the Cathedral above and the vats of Mariposa below — and the army, masterless, scattered. New California kept its differences.

Then the Dweller walked home to Vault 13, and the door opened to the width of one overseer. The thanks were sincere and the sentence was exile: the hero had seen too much sky, and the young would follow such a person up and out, and the vault could not spare its young. The Dweller turned north into the wastes and in time founded a village called Arroyo, whose story is another record. Vault 13 was saved, sir. It kept its door shut to prove it.
