The Wars of Vindication: The Plot That Threatened to Tear the Assassins Apart

On the day the Grand Master of Assassins was murdered in his chambers, a package arrived at the Inquisition. Inside was a signet ring and a note in an anonymous hand. The note claimed that this was the real ring of office, and that the ring on the dead man’s finger was a fake. When the inquisitors forced open the mausoleum and looked, they found the note was right. So who was the body? Who sent the package? And where, reader, was the real Grand Master? The answers lie in the Wars of Vindication, the hidden civil war that nearly destroyed the Imperium’s most feared weapon, and in the official lie written to cover it up.

The Officio Assassinorum

First, the organisation. The Officio Assassinorum is the Imperium’s secret office of murder, divided into hidden temples, each with its own method. The Vindicare are snipers; the Eversor are frenzied killers; the Venenum kill with poison; the Callidus use the shape-altering drug polymorphine to wear other people’s faces, and are notorious for infiltrating other branches of the Imperium as courtesans or servants. At the top sits the Grand Master of Assassins, who is also one of the High Lords of Terra.

Its weapons are so dangerous that, Imperial sources say, only the High Lords themselves can sanction the deployment of an assassin, fearing their own tools may be turned upon them. That fear was not idle. It is said that in the distant past Grand Masters used assassins for their own ends, and a reign of terror gripped even the High Lords. The Wars of Vindication are the darkest chapter of that history.

Vandire’s Reign of Blood

The story begins with Goge Vandire, the 361st High Lord of the Administratum. Early in the 36th millennium he seized control of the Ecclesiarchy in what one codex calls a military coup and took both the role of Ecclesiarch and High Lord of the Administratum, plunging the Imperium into the Age of Apostasy and its bloodiest stretch, the Reign of Blood. He was, the same source says, a paranoid megalomaniac who saw treachery everywhere. Countless millions died, and entire worlds were destroyed by his madness.

Vandire did not rule by sermons alone. He bribed and blackmailed his way into the Adeptus Astra Telepathica, the Ecclesiarchy, the Administratum and the Imperial Guard. Inevitably, he also turned to the Imperium’s assassins. His reign ended when Alicia Dominica, at the head of the warrior women who became the Sisters of Battle, beheaded him. But the rot he had planted outlived him, and a few months after his death, the Imperial Palace shook with gunfire again.

A Pattern in the Deaths

Our best witness to what followed is the Grand Master himself, in a confession sealed in the vaults of the Administratum. He tells us he resisted Vandire relentlessly and refused him any foothold in the Officio Assassinorum. Yet as Vandire’s grip tightened, reports of dead and missing officials began to pile up, every killing flawless and untraceable, and every death convenient for Vandire. The question, he wrote, was no longer whether Vandire had a man inside the Officio, but who that man was.

To an outsider, the killings pointed everywhere: some looked like the Grand Master’s own Vindicare Temple, others bore the savagery of the Eversor, and many poisonings could easily have been Venenum work. The Grand Master reasoned that Vandire could not have bought the whole Officio, since its secrecy meant even a High Lord knew only a few of its members. The only temple able to infiltrate the Officio from inside, and wear the faces of other assassins, was the Callidus.

Tziz Jarek, the Passed-Over Rival

At the head of the Callidus Temple stood its Director Primus, Tziz Jarek, the Grand Master’s arch-rival. Jarek had been favoured as the next Grand Master. But when the post fell vacant, he was away leading an elite Callidus team infiltrating a Dark Eldar warband, and had not been heard from in over a year. Assuming him dead, the High Lords gave the office to his rival. Jarek came home victorious to find his prize taken by a man of his own age, and knew he would be too old or dead before it fell vacant again.

Unless, of course, the new Grand Master suffered an accident. Vandire knew of the rivalry; he had been among the High Lords who appointed the Grand Master. Having failed to win the Officio through its master, the report argues, he turned to the man who hated him. Jarek, it seems, had high-ranking officials in other temples assassinated and replaced with Callidus agents, and through them Vandire’s corruption spread through the Officio like a malignant tumour.

The Ring and the Double

Vandire’s death turned Jarek’s position from profitable to deadly. Across the Administratum, offices were ordered to purge anyone suspected of siding with the fallen Ecclesiarch, and the Officio Assassinorum does not forgive failure. A purge there would spare no one, however unwitting. The Grand Master saw what came next as if reading a script: if he were Jarek, he would kill the Grand Master, take his face with polymorphine, and purge the Officio himself.

So he prepared. He had a fake signet ring made, and a loyal Callidus assassin took on his identity and his chambers. One night Jarek and two other assassins entered those chambers and killed the double. Jarek put on the dead man’s face and the fake ring and sat down in the office he had always wanted. The real Grand Master disappeared.

War Inside the Imperial Palace

Then he declared war on his own organisation. His reasoning is chilling: an Officio that could be corrupted by a few individuals had to be smashed before it could be rebuilt. Jarek might wear the ring, but only the true Grand Master knew every secret, and only he could reach the Officio’s hidden arsenals. With a band of loyal assassins, he turned the Palace into a hunting ground. Entrances were sealed, though the High Lords had given no order, and many of the Palace’s residents barricaded themselves in their chambers.

Loyal assassins stalked rogue Eversor through the corridors. Vindicare snipers lay in air ducts and alcoves, shooting traitors down. Hideouts were destroyed with demolition charges, some so powerful that whole sections of the Palace collapsed and many innocents died. Weapons long banned were brought out of the old arsenal: one account speaks of gene-sympathetic nerve gases in the corridors and neutronic warheads that destroyed whole wings. One by one, the assassins who had served Vandire or Jarek were brought down.

The Last Confrontation

Finally only Jarek remained. The Grand Master confronted him in his own chambers, the ones he had abandoned to a double. Jarek lay waiting, armed with Callidus wargear: a C’tan phase sword with a longer reach than any hand-to-hand master could match, and a Neural Shredder. But the Grand Master had planned for this moment from the start. A haywire charge was hidden inside his desk, keyed to a spoken code word, and among the ceremonial Exitus weapons on the wall, one pistol was loaded.

He spoke the word. The pulse drained Jarek’s weapons, and in that instant of shock the Grand Master took down the pistol and fired twice. The Exitus rounds tracked Jarek’s heat signature as he tried to dodge, and both struck home. The rounds were chosen to leave no trace, and the Grand Master swapped the magazine for a conventional one before hanging the pistol back on the wall.

A Confession in the Vaults

Here the two halves of the record meet. After the fighting, Inquisitor Jaegar opened his investigation with the package and the ring. The real ring held a ruby; the fake, found on the dead man in the mausoleum, held a data crystal bearing an Administratum vault code. The vaults of Terra are so vast that finding one chamber could take years. When Jaegar found it, inside was the Grand Master’s report. In it the Grand Master took his share of the blame. He had been foolish to believe the Officio could stand apart from a man like Vandire, and he could not lead the new Officio while belonging to the old. He resigned, vanished, and left the rebuilding to the Inquisition, signing off with the old motto Exitus Acta Probat: the outcome justifies the deed. Whether he still lives, Jaegar admitted, is unknown.

The Ordo Sicarius and the Official Lie

Jaegar’s recommendations reshaped the Officio. According to his memoirs, the temples were scattered to separate locations, so that if one fell to alien, daemonic or heretical influence the others would remain untainted. Any assassination now needed a two-thirds vote of the Senatorum Imperialis, the High Lords’ council. Every mission was to be followed by a detailed report open to Inquisitorial inspection, and all assassins except the Eversor were to undergo regular psycho-doctrination. To watch them, Jaegar founded the Ordo Sicarius, and claims to have placed its agents inside every temple.

Then he proposed a lie. To avoid embarrassment, he recommended that no trace of the truth should come to light, and that Imperial records should read only that in the anarchic Wars of Vindication the Grand Master fell to the assassin’s knife, and that afterwards the High Lords took special care to control the Officio so that, in theory, only traitors and heretics need fear it. That sentence survives, almost word for word, in later Imperial accounts. The cover story worked.

The Wars of Vindication did not end with a victory. They ended with a dead traitor, a ruined Officio, a Grand Master who chose exile, and a history rewritten to hide what had happened. The Imperium’s assassins are feared because they are perfect. The secret the vaults kept is that, for a few months in the 36th millennium, they were turned on each other, and the reforms that followed were designed to make sure it could not happen again.

Questions from the Archive

What were the Wars of Vindication in Warhammer 40k?

The Wars of Vindication were a civil war inside the Officio Assassinorum, fought in the Imperial Palace a few months after the death of Goge Vandire in the 36th millennium. Assassins corrupted by Vandire, led by Tziz Jarek of the Callidus Temple, tried to seize the office of Grand Master. The true Grand Master survived and hunted them down, wrecking the organisation in the process.

Who was Tziz Jarek?

Tziz Jarek was Director Primus of the Callidus Temple, the shapeshifting assassins who use the drug polymorphine. He expected to become Grand Master, but was away on a long mission against the Dark Eldar when the post fell vacant. According to the Grand Master’s report, Vandire exploited Jarek’s resentment to gain a foothold in the Officio Assassinorum.

Did the Grand Master of Assassins really die in the Wars of Vindication?

Officially, yes: Imperial records say the Grand Master fell to the assassin’s knife. The secret report tells a different story. The Grand Master placed a Callidus double in his chambers, and it was the double Jarek killed. The real Grand Master survived, killed Jarek, then gave up his office and vanished. Whether he still lives, the Inquisitor who investigated did not know.

What is the Ordo Sicarius?

The Ordo Sicarius is the order of the Inquisition that watches the Officio Assassinorum. According to Inquisitor Jaegar’s account, it was founded after the Wars of Vindication. Its agents were placed inside each assassin temple, and it monitors assassinations and the regular mental conditioning of assassins. Other sources agree that the Inquisition gained oversight of the assassins after these events.

Who can order an Imperial Assassin to kill?

Imperial sources say only the High Lords of Terra may sanction the deployment of an Imperial Assassin. After the Wars of Vindication, according to Inquisitor Jaegar, any assassination required a two-thirds vote of assent in the Senatorum Imperialis, and every mission had to be followed by a detailed report open to Inquisitorial inspection at any time.
