Consider the scene, as the archives preserve it a thousand times over: a chamber sealed against the light, a plinth of dark stone, and a bundle of black cloth bound with silver string. Within the cloth, seventy-eight wafers of liquid crystal, utterly blank — no image, no marking, nothing but a soft white glow that might be a trick of the eye. A psyker breathes. The cards are laid face-down. And when they are turned, they are no longer blank.
This is the Emperor’s Tarot, and it is the closest thing the Imperium of Man possesses to a conversation with its god. The Master of Mankind sits immobile upon the Golden Throne, His body long past the capacity to speak. Yet the Imperial creed insists that His will still moves through these cards; that the same terrible intellect which sustains the Astronomican and holds the Ruinous Powers from the door also, somehow, has attention to spare for a lone astropath on a forgotten voidship, asking whether the passage ahead is safe.
Whether that is truth or the most magnificent superstition ever devised, the archives cannot say. But an Imperium of a million worlds acts as though it were true, and that is a fact of considerably greater consequence.
What the Emperor’s Tarot Is: Seventy-Eight Wafers of Psychoactive Crystal
The classical deck numbers seventy-eight cards — psychoactive liquid-crystal wafers held to be linked to the thoughts or prophetic visions of the Emperor Himself. Common belief throughout the Imperium holds that He designed the deck, and that its cards are psychically imbued with His influence by virtue of that design. One account preserved in the Inquisitorial records puts it with unusual clarity: the Emperor trawls, the Emperor sifts unsleepingly, and the cards sift with Him — straining the tides of fate, of probability and improbability, of strengthening and waning influence.
An unused deck is entirely black and blank. Some are wrought of humbler stuff — plastic, wood, bone — for not every world can afford crystal, and the practice is old enough to have accreted a thousand cheap imitations. The finest are made of lorelei, the psychically active substance also used in psychic hoods and force weapons, which can be beaten into wafers near as thin as paper. Lorelei grants far stronger readings. It also invites far greater risk. The archives note, drily, that this trade-off has never once discouraged the sort of person who seeks out such a deck.
The Cost of a Card: Lifetimes Spent on a Single Image
A seer’s account from the Iron Hands’ records gives the measure of the thing. It could take centuries to master the Tarot — to learn every combination of cards, every subtle nuance of meaning, to read every play of warp-light across the psychoplastic-impressed images. Few practitioners are ever granted such time.
And the making is no swifter. One scribe-artist might labour an entire lifetime lovingly hand-crafting a single card. A complete deck of seventy-eight, resting upon its plinth, was reckoned worth a planetary governor’s ransom. Some sources hold that the images are crafted by blinded artisans — hands that have never seen what they render, which the theologians of the Ecclesiarchy consider the whole point. Between castings, decks are kept in psionically shielded dark boxes, lest they be contaminated by stray thought or lesser presence.
Laid out in their entirety, the cards form an allegorical image of the entire Imperium: a realm of a million worlds and untold billions of souls, its heroes and its enemies rendered in miniature. It is a portrait of the human dominion, and it fits in a box.
Discordia, Adeptio, Creatio, Mandatio: The Suits of the Lesser Arcanoi
Above the suits sit the major arcana — the trumps, the great signifiers. Beneath them run four suits of lesser arcanoi, though the naming varies from sector to sector and deck to deck.
Discordia is the suit of strife, though it may also signify authority; its cards bear the enemies of the Imperium, xenos and warp entities both. Adeptio is the suit of vigorous work — heroes, servants, great deeds. Creatio is fertility. Mandatio is government, stability, wealth and leadership.
Yet no two decks are truly alike. Other suits are attested: Executeria, arcana of the unknown, of exploration, of the future and the mind; Concordia, of which the records are thinner. Some decks demote major arcana into suits entirely. And in the Macharian Sector, the archives whisper, many decks show fleeting afterimages of the Lord Solar himself — glimpsed and gone before the eye can fix on them.
The cards are known to change their images outright, which shifts their interpretation with them. A reader who learned a deck in youth may find it a stranger in old age.
The Casting: Cardinals, Signifiers and Inverted Meanings
The rite demands a fresh deck, still blank, still wrapped. The psyker must take exceptional care not to touch the wafers beforehand, lest the casting be corrupted by their own contamination. The cards are laid face-down, then turned one by one and read as they come.
Four cards are drawn in the common form — the four cardinals of the casting. The first is preeminent, governing all that follows. The second and the fourth are signifiers, lending clarity to the cards preceding them. The third may stand in direct opposition to the first. The final cardinal flavours every card before it. Some castings draw five. And on rare occasions, the records note, cards rise unbidden from the deck to land atop the cardinals already turned — an event no reader welcomes.
An inverted card does not merely soften its meaning. It reverses it utterly.
The Peril: Why Only the Desperate Cast Alone
Casting the Tarot is not a parlour trick, and failure vastly outnumbers success. The gentlest failures are the misread card, or the true card that falls treacherously into some clouded corner of the future, leaving the supplicant more confused than before he asked.
The worst is considerably worse. Reaching into the immaterium for answers announces that you are reaching, and things attend to such announcements. A botched casting may draw the notice of warp entities; at the extreme, it ends in daemonic possession. For this reason even the disciplined psykers of the Scholastia Psykana will typically set three readers to a casting, or at minimum two, spreading the burden and warding against the perils of the warp. Only the truly desperate cast alone.
There is stranger danger still. The Inquisitorial testimony of one Jaq Draco records a Tarot bound so tightly to its owner that he could not destroy it, and could not prevent an enemy from reaching through it at a distance. The Tarot is a unity, a web, he insists to a companion who suggests simply shooting a hole in the offending card. The deck, he warns, has a life of its own.
The Great Leveller: Faith, Doubt and the Emperor’s Will
For all its expense and peril, the Tarot occupies a curious place in the Imperial soul. As the records of the Baneblade crews have it, the Tarot is one of the few levellers in the Imperium. Highborn, lowborn, spacer, planetsider, scum — it does not matter who you are or where you are. So long as you have a reader, anyone may scry for the Emperor’s will. And sometimes, it is said, He answers, even to the lowliest.
Doubt survives alongside the faith. The tank ace Bannick regarded the Tarot with deep suspicion, too worldly to take it at face value — and yet he was a man of faith, and the saints’ tales are thick with proofs of its efficacy. That tension is the honest Imperial position. The condemned soldier’s chronicles of the Last Chancers preserve a colonel’s verdict: he does not doubt the Emperor can extend His will to shape lives, nor that there are many tales of Him guiding His followers to victory through the Imperial Tarot — but he refuses to ascribe every outlandish event to divine intervention.
The practice is older than the Imperial Cult that venerates it. The Tarot was already widespread during the Great Crusade, in an age when official doctrine dismissed it as pure superstition. The sagas hold that Malcador the Sigillite himself read crystal wafers to scry the vagaries of fate — which, if true, means the Emperor’s own regent trusted the cards while the Emperor’s own Truth denied them.
No record survives to reconcile that. Perhaps none was ever meant to. The archivists of Terra content themselves with this: the deck is blank until it is not, and something writes upon it.
