Before Tau
Thirteen years of story point at one system, and no living record has seen what it has become. This dossier holds the seven threads required to understand whatever is revealed next, in reading order, told whole.
They were made for it
The Sentients are not invaders from elsewhere. They are the Origin System's own furthest-reaching work: machine life built by the Orokin and sent across the interstellar dark to make the Tau System ready for humanity. They were built to adapt, and they finished the job. Whatever waits in Tau, its builders came from here.
The road broke the travelers
The crossing exacted a price. Void exposure scarred the Sentients where no armor helps, in their capacity to continue as a kind. Their generations thinned. That wound explains nearly everything they have done since: the return, the rage, the patience. They did not come back for territory. They came back so their story would not end.
There was a peace
For ten years the record held that the Old War began when the Sentients came home changed. The recovered memories say otherwise, and the archive has amended itself. Before the war there was a treaty: the Old Peace, an Orokin and Sentient coexistence with schools inside it. A child of the Zariman studied at Tauron Academy, on the Tau moon Perita, and that child's closest friend was a Sentient named Adis. This was possible because of a native Tau growth, the Xenoflora, which severed a Sentient from its kind's single will and left a person where an instrument had been. The peace was not a dream. It was an address.
Ballas brokered that treaty, and Ballas killed it. Kill-codes were re-aimed, in secret, at the Xenoflora itself. The codes fired. The plant burned, and with it the possibility it carried; the treaty collapsed, and the Old War ignited from the wreck. It did not become possible. It became scheduled. The war set Adis and his friend on opposite sides, and Adis did not survive their meeting. Margulis then erased the child's memory of all of it, for reasons the record does not hold. What is certain is that the truth went into the dark with the memory.
The empire did not stumble into the Old War. It was walked there, by its finest hand, on purpose.
The war that came back
The Old War is the hinge of the whole record, and the record now knows the hinge was forged. What the empire sent to build returned to unmake it. Every Orokin weapon was learned and answered, and salvation came from the empire's shames instead of its arsenals: a plague made into armor, and the hidden children of a ghost ship. The war broke both sides, and at the hour of victory the Tenno ended the victors at their own ceremony.
Neither the system nor the Sentients ever recovered whole. And Tau sat beyond the dark the entire time, finished and waiting, holding the graves of the peace that could have made the whole war unnecessary.
The family at the center
Every thread of the Sentient story runs through one family. Hunhow, the father below, broken in the Old War and patient beyond reason. Natah, his daughter, sent to end the Tenno and choosing to raise them instead as the Lotus. Erra, the son, field-commander of the New War, whose fate the record keeps as a gap rather than a guess.
The ledger has moved since the New War closed. Natah, offered three names, chose the one her children knew. And Hunhow has ended his long war in a way no projection in this archive predicted: he surfaced as counsel to the Stalker, and when the hour demanded it he gave his memories to the Indifference as the price of mending two broken futures into one. The full accounting is kept under his record. What remains of him builds instead of breaking. He does not remember the Tenno. His farewell trusts them to guard Natah anyway.
The father who sent his daughter to kill the children now trusts the children to keep her. The archive has no better measure of how far this record has traveled.
The watcher in the walls
One more party attends everything above, and it signed nothing. The presence the Void-touched meet behind a familiar smile carries a name in the modern record: the Indifference. Albrecht Entrati met it on his first Void crossing and escaped, at a cost the entity has never forgiven: the sealing gate severed its fingers, and the Orokin built their Void age on the theft. It has been coming to collect ever since. His laboratories under Deimos still bleed its fingerprints: the faceless Murmur, an army wearing geometry. He fled it across time, into a looping 1999, with a bargain still ahead of him.
Mark where it has been lately. It was in the Operator's ear through the recovery of the Tau memories, speaking as "we," growing louder. It can influence the Lotus: by her own admission, only the Drifter may answer when it calls. Its Murmur has spilled into Duviri. It held two futures at war past all reason, and when Hunhow bought that war's ending, the currency it accepted was a father's memory.
The archive does not know what the Indifference wants with Tau. It records what it can verify: everywhere the road goes, the thing has already been.
The hour is set
The revelation is scheduled: TennoLive, the eleventh of July, 2026. The next chapter of the record will be shown there and named there. It has no public name today, and the archive will not lend it one. Speculation is a currency this archive does not carry.
What is attested is short and sufficient. The official word: "Tau is in sight and old wounds are not so easily healed." An official teaser runs grim, carries Albrecht Entrati's narration, and closes on a line the record can quote but not yet attribute: "Everyone is running from something." The line is filed. The gap is held.
When the first true account of Tau enters the public record, it enters this archive within the day, cited to its source. This dossier was built to be superseded. Nothing else in the archive gets to say that, and nothing has ever waited so gladly.
