Lore:

  • Crafted during the early years of the First Kingdoms by an esoteric lodge of magistrates in Assyria, this ocular lens was developed under strict Hermetic principles asserting that objective truth is an elemental vibration of the universe, whereas deliberate deception introduces a destabilizing dissonance into an individual’s personal Weave. Drawing upon ceremonial rites derived from the ancient Emerald Tablet and Golden Dawn invocations of divine balance, early truth-seekers engraved geometric sigils upon cold brass to construct an instrument capable of measuring the friction between a speaker’s stated word and their conscious reality. Rather than reading thoughts directly
  • Ritual 73 of the Emerald Pendulum
    • Lore
      • Penned by early Hermetic initiates walking the lower rungs of Saṃsāra’s spiritual ascent, “Ritual 73” outlines the binding of subtle telluric currents to unmask discord in mortal speech. Esoteric tradition holds that spoken falsehood distorts the micro-vibrations of the practitioner’s local sphere. By anchoring these micro-currents through a consecrated geometric weight, an initiate can perceive disharmony long before it manifests as overt deceit.

Description

  • A pointed, hexagonal plum-bob carved from clouded pale beryl, suspended from a nine-link chain of braided electrum. The facet faces are etched with miniature Hermetic sigils corresponding to the sphere of Mercury and the elemental balance of Air. When resting against skin, it remains cold and inert; when held by the chain, it subtly resists erratic motion.

Detailed Stats

  • Item Tier: Tier 1
  • Rarity: Common
  • Weight: 0.25 lbs
  • Attunement: Required (Requires a 10-minute meditation tracing Hermetic seals)
  • Durability: 25/25
  • Material: Beryl stone, electrum chain

Passive Magic

  • Vibrational Resonance: While worn against the skin, the stone grows noticeably colder whenever a sentient creature within 10 feet knowingly speaks a direct falsehood. It does not identify the liar, only the presence of the deception.
  • Hermetic Poise: The wearer gains a +1 bonus to Insight checks made during formal negotiations, debates, or diplomatic interrogations.

Activable Magic

  • Caduceus Swing: Once per rest, the bearer may suspend the pendulum by its chain and whisper the opening verse of Ritual 73 as an action. For 1 minute, the pendulum swings in a clean, rhythmic circle. If a targeted speaker within 15 feet tells a lie, the pendulum abruptly snaps into a violent, irregular wobble, revealing the statement to the user.
  • Sealing of the Tongue: Once per day, the user may touch the pendulum to an unsealed document, contract, or letter while chanting the sealing formula. The paper glows faintly with a pale green seal for 1 hour. If any reader knowingly misquotes or lies about the written contents within that hour, the parchment emits a faint sulfurous odor.

Commerce and Exchange of the Emerald Pendulum

  • Magistrate Supply Scriveners and Legal Scriptoria: Situated within the judicial wards of capital cities and regional administrative centers, these austere, wood-paneled scriptoria cater directly to court clerks, adjudicators, and official notaries. Glass display cases near the intake desks hold calibrated dowsing tools, balance scales, and inscribed verification seals. When an avatar approaches an official court scrivener to sell the pendulum, the clerk suspends the weight over an inkwell and speaks a standardized false balance sheet to verify its vibrational responsiveness; a Tier 1 seller experiences a standard 10% haggle reduction on the item’s perceived value, securing a payout of 9 silver pieces deposited directly into the seller’s World Bank ledger. If an independent investigator or advocate attempts to purchase the pendulum from the scrivener’s inventory, the baseline cost is set at 10 silver pieces, though an avatar openly wearing the badge of the Scribes’ Guild or Civil Bailiffs’ Faction receives the corresponding 10% faction discount, reducing the purchase price to 9 silver pieces.
  • Esoteric Lodges and Hermetic Bookbinderies: Tucked inside multi-level limestone tenements or within the cloistered arcades of prominent temple districts, these quiet sanctums deal in ritual focuses, ceremonial daggers, astronomical charts, and consecrated metals. The air inside is thick with burning storax and cedarwood, and goods are kept wrapped in unbleached silk to prevent premature spiritual exposure. The resident adept tests the pendulum by checking the precision of the Mercury sigils against an astronomical chart before making an offer; because of the esoteric purity required for the beryl and electrum link, the merchant agrees to purchase the item from a Tier 1 initiate for 11 silver pieces credited to the bank. When an unaligned customer wishes to purchase the item from the lodge display to aid in philosophical disputations or personal transformation, the adepts demand a premium cost of 13 silver pieces, while an initiate of the Hermetic order or an affiliated philosophical society can purchase the piece at the recognized member rate of 11 silver and 7 copper pieces.
  • Pawnshops and Curiosity Bazaars: Located near high-traffic wagon terminals, central caravan yards, and city gates, these chaotic storefronts are crowded with unclaimed estate remnants, used adventuring gear, and unverified trinkets hanging from wall pegs. The shopkeeper is a generalist who inspects the item with a basic magnifying glass to ensure the electrum links are genuine metal rather than plated tin, offering the seller an aggressive markdown of 8 silver pieces with an immediate entry into the World Bank records. If a wandering traveler or adventurer spots the beryl stone amidst the clutter and wishes to buy it off the shelf, the merchant sets the sticker price at 11 silver pieces, refusing any discount unless the buyer holds verified standing with the local Merchant League.
  • Frontier Guild Outposts and Mercenary Supply Posts: Set on the perimeter of untamed frontier territories, monster-dense borderlands, or near coastal wharf roads, these practical, heavy-timbered warehouses provide supplies for bounty hunters, caravan guards, and expedition leaders. Tools of verification are kept in locked iron lockboxes behind the counter to prevent contract disputes during party recruitment. When a member of an adventuring company brings in the pendulum to exchange it for travel rations or ammunition, the quartermaster values the tool strictly for its functional utility in vetting new hirelings, purchasing the piece for 9 silver pieces routed through the World Bank. When an adventuring party seeks to purchase the pendulum to protect themselves against deceptive contracts in the wild, the merchant charges 12 silver pieces due to the remoteness of the frontier and the high cost of transit from the interior manufacturing centers.
  • Shadow Alleys and Contraband Vaults: Concealed beneath dark river wharves, inside dry cisterns, or operating within the backrooms of unregulated dockside taverns, these clandestine operations trade strictly without paperwork, guild oversight, or World Bank involvement. Fences and black-market fixers value truth-detecting devices highly for interrogating suspected informants, discovering undercover city watches, and ensuring loyalty among smuggling rings. When an avatar sells the pendulum to a black-market broker who urgently requires an untraceable lie-detection focus for an impending gang dispute, the broker bypasses the standard merchant rates and pays a desperate sum of 20 silver pieces in physical, heavy minted coin handed over immediately. Conversely, if an outsider seeks to buy the pendulum from an illicit dealer to avoid having the purchase logged by tax collectors or official bailiffs, the dealer demands an inflated price of 22 silver pieces, payable solely in raw precious metal coin with no questions permitted.

Tactical and Environmental Applications of the Emerald Pendulum

  • High-Seas Caravels and Pirate Harbors: On the open ocean where the dominant east-to-west currents dictate trade routes and maritime discipline is strict, false navigation logs and mutinous talk threaten entire crews. For defensive roleplay, an avatar acting as first mate or passenger leans casually against the companionway rail during night watches, holding the electrum chain beneath a heavy storm coat. As the ship’s navigator reports anomalous heading coordinates or an undercover buccaneer claims an innocent intent while inspecting the hold, the bearer feels the beryl chill against their chest, silently alerting the party to an impending navigational sabotage or ambush before sails can be reefed. During storm conditions, this tactile warning allows the party to prepare reactions or verify emergency steering commands before vessel damage occurs. In offensive roleplay during boarding actions or coastal pirate negotiations, the user openly suspends the pendulum while interrogating captured raiders on the deck. Chanting the opening verse of the rite, the user watches the steady, circular swing over the prisoner’s throat; when demanding the true location of a submerged reef cache or the identity of an aboard conspirator, a violent wobble in the swing exposes the captive’s evasion immediately, forcing the user’s companions to press the psychological advantage and bypass deceptive stalling tactics in the heat of combat.
  • Underground Megacities and Smuggling Caverns: Within sprawling subterranean settlements and damp, subterranean cave systems illuminated by bio-luminescent moss and steam conduits, deceit flourishes in shadowy alleys and crowded black-market bazaars. Defensively, the bearer moves through crowded under-city markets with the plum-bob tucked beneath an insulated vest. When an undercover fixer or corrupt guard offers safe passage through a restricted mine shaft, a sudden icy prick against the wielder’s collarbone reveals that the promised path is a trap leading into a predatory monster den or a rival guild’s extortion zone, prompting the party to turn back before entering the choke point. Offensively, when cornering a contraband runner or an infiltrator within a dim vault, the wielder extends the electrum chain as an action, calling upon the sphere of Mercury. As the beryl catches the faint glow of steam lanterns, the user demands confirmation on whether an alarm lever was pulled; if the stone snaps into an irregular wobble, the avatar uses the verified deceit to immediately trigger a surprise attack with a sidearm or dispatch the runner before reinforcements arrive, preventing the enemy from maintaining a coordinated defensive perimeter.
  • Capital Royal Courts and Feudal Council Chambers: Amid the gilded corridors and marble halls of an island nation’s central city, words are wielded with lethal precision by hereditary nobles, royal advisors, and court viziers. For defense, an adventuring emissary stands beside the throne with the pendulum resting discreetly inside an open lapel. While a rival ambassador from a distant continental island pledges peace or a lord-in-waiting insists the royal treasury is empty, the cold stone against the skin unmasks political subversion and treasonous promises in real time, preventing the party from signing disastrous treaties or walking into noble assassinations. Offensively, during open court debates or high-stakes trials overseen by city magistrates, the wielder invokes the Sealing of the Tongue upon the official petition or parchment treaty. When a dishonest minister takes the podium to misquote the treaty’s terms or lie about tax allotments, the user draws immediate attention to the faint sulfurous odor rising from the parchment, turning the assembly’s outrage against the deceptive official, shattering their social standing, and driving the political balance of power directly into the party’s hands.
  • Wilderness Frontier Camps and Borderland Garrisons: Along the fringes of uncharted island interiors where isolated outposts and palisades are surrounded by lethal wildlife and roving monsters, trust between mercenary companies is a matter of life and death. Defensively, while sitting around the camp stove during downtime, the user uses the pendulum’s passive coldness to vet transient strangers or hirelings claiming their supply wagons were destroyed by beasts rather than stolen by outlaws, identifying bad actors before the camp sleeps. Offensively, when negotiating with a hostile wilderness clan or demanding terms of surrender from a trapped band of raiders in a mountain pass, the user suspends the stone over the leader’s map. Chanting the Hermetic balance formula, the user instructs the raider chief to point out the clear patrol route through the monster-dense valley; any sudden jerk or stutter in the pendulum’s rhythm identifies a false trail immediately, allowing the party’s scouts to set up an ambush along the true flanking route instead of marching into a canyon trap.
  • Copter City and Industrial Airship Docks: High above the clouds where tinker gnomes sustain airborne platforms via massive mechanical rotors and steam pulleys, technical sabotage and industrial espionage present constant peril. Defensively, while riding a transport zeppelin or walking the vibrating sky-docks, the bearer keeps the pendulum tuned against their palm. When an engineer claims an arcane battery or rotor gearbox is operating within normal safety tolerances, a sharp chill across the skin signals that the technician is covering up critical component failures, allowing the party to take defensive precautions, secure emergency gliders, or dismount before a catastrophic structural collapse. Offensively, when confronting an industrial saboteur caught tampering with a steam valve, the user activates the Caduceus Swing amidst the roaring engines. Asking rapid-fire questions regarding which lever disarms the boiler override, the user reads the erratic oscillation of the beryl weight to identify the correct mechanical sequence despite the saboteur’s shouts of false instructions, defusing the airborne disaster before the clockwork city loses buoyancy.

Perception of Activation:

  • Sight:
    • User’s Perspective: Upon reciting the ritual words, the pale green beryl stone ceases any natural swaying and begins tracing a precise, unbroken circular orbit in the air. The etched Hermetic sigils along its hexagonal facets ignite with a soft, phosphorescent emerald radiance. When a falsehood is spoken within the area, the clean circular path instantly fractures into a jagged, violent wobble, and the sigils flash a brief, stark white across the crystal faces before returning to green.
    • Observer’s Perspective: Observers see the small stone suddenly suspend itself with mechanical rigidity, swinging in an unnatural, rhythmic circle on its braided chain. When a lie is voiced, the weight visibly stutters, jerking sideways as if struck by an invisible hammer, while the faint green luminescence pulses brightly against the user’s fingers.
    • Positives: The distinct change in movement and luminous flash provides an unmistakable visual confirmation of deception, allowing the wielder to detect dishonest testimony without relying entirely on physical cues.
    • Negatives: The bright flare and chaotic oscillation are easily seen by anyone looking toward the user, making it obvious to skilled manipulators that an arcane verification device has been triggered.
  • Hearing:
    • User’s Perspective: As the stone begins its circular swing, a subtle, high-frequency hum resonates along the electrum links, resembling the pure tone of a struck silver chime. The moment a falsehood is stated, this harmonic chime breaks with a sharp, dry crackle like a static discharge snapping right next to the ear.
    • Observer’s Perspective: Nearby individuals hear a low, continuous metallic vibration that abruptly cuts out with a faint, brittle pop when the speaker utters an untruth.
    • Positives: The acoustic shift acts as an immediate auditory alert, informing the user of a lie even if their gaze is turned away from the pendulum itself.
    • Negatives: The sudden crackle can disrupt delicate conversations, and keen-eared creatures or guards can trace the unusual acoustic pop back to the user.
  • Smell:
    • User’s Perspective: A crisp, sterile scent of ozone and chilled mineral water washes upward from the bob during truthful speech. When deception disturbs the swing, the air turns sharp with the dry, acrid reek of burnt copper wire and heated sulphur.
    • Observer’s Perspective: Those standing within arm’s reach notice a brief draft of cool, mountain-air scent that suddenly sours into a faint smell of singed metal whenever a false claim is made.
    • Positives: Provides a tertiary sensory indicator that functions effectively even if the user has been temporarily blinded or deafened.
    • Negatives: The sulfurous stench lingers in small, enclosed rooms, irritating the nostrils and alerting sensitive hunting beasts to the presence of magical tampering.
  • Taste:
    • User’s Perspective: A cool, clean taste like cold well water coats the tongue while the device swings true. The instant a lie disrupts the weave, a harsh, metallic bitterness floods the back of the palate, tasting of tarnished brass and saltpeter.
    • Observer’s Perspective: Observers do not perceive direct taste sensations, though they may notice the user instinctively swallowing or grimacing.
    • Positives: Offers internal physical confirmation that cannot be masked or deceived by illusions playing upon the eyes or ears.
    • Negatives: The lingering bitter taste leaves the user’s throat dry and scratchy, causing involuntary throat clearing during diplomatic discourse.
  • Touch:
    • User’s Perspective: The electrum chain feels smooth and carries a faint, rhythmic pulse like a steady heartbeat between the user’s thumb and forefinger. When a falsehood occurs, the chain violently snaps taut, transmitting an icy, stinging electrical tingle directly into the wielder’s nerve endings as the stone drops several degrees in temperature.
    • Observer’s Perspective: The user’s hand visibly twitches as the chain jerks, though observers feel no external physical sensation unless touching the user directly.
    • Positives: The tactile jolt delivers an instantaneous, reflex-level signal that bypasses any sensory confusion in chaotic environments.
    • Negatives: The stinging frost-shock can cause an involuntary finger tremor, making it difficult to maintain a steady grip or carry out fine manual tasks with that hand immediately afterward.
  • Extra-Sensory Perceptions:
    • Mind’s Eye Telluric Alignment:
      • User’s Perspective: Through the Mind’s Eye, the surrounding space manifests as an array of fine, taut geometric lines representing local telluric stability. Spoken truth maintains these lines in smooth, parallel harmony, whereas a deliberate untruth causes an abrupt planar knot to cinch and twist the threads around the speaker’s head, appearing as an illuminated fracture in the local Weave.
      • Observer’s Perspective: Other avatars actively observing through their own Mind’s Eye see the faint outline of a glowing green seal briefly compress and distort around the speaker before dispersing into ambient magical currents.
      • Positives: Visualizes the focal origin of the falsehood, revealing which specific individual spoke the deceit when multiple voices speak at once.
      • Negatives: Viewing the sudden unraveling of structural telluric threads can strain cognitive focus, occasionally inflicting brief mental fatigue during extended interrogations.
    • Astral Dissonance Sensing:
      • User’s Perspective: The user feels an intuitive spiritual shudder, as if an oily ripple passed across the surface of their soul, signaling that the metaphysical law of balance has been transgressed by the speaker.
      • Observer’s Perspective: Highly attuned planar entities, spirits, or nearby avatars sense a sudden tightening in the ambient psychic pressure of the room.
      • Positives: Instantly differentiates between a harmless verbal omission and a calculated, malicious deception intended to cause harm.
      • Negatives: The persistent psychic friction can leave the user feeling emotionally drained, fostering an instinctive sense of paranoia after successive activations.

Hermetic Emerald Pendulum Fabrication Recipe

  • Materials Needed:
    • One Tier 1 Magic Crystal (coin-sized and coin-weighted, harvested from an adult magical creature).
    • One uncut nodule of pale, semi-clouded natural beryl (free of large structural cleavage cracks).
    • One small ingot of electrum (an even alloy of native gold and native silver).
    • Nine drops of mercurial solvent or purified plant distillate (used to cleanse the mineral surfaces).
    • One measure of fine polishing grit and diamond dust (for facet faceting).
  • Tools Required:
    • One lapidary cutting wheel and hand dop stick.
    • One jeweler’s anvil and precision chasing hammer.
    • One set of diamond-point scribing burrs.
    • One spirit burner with a miniature blowpipe.
    • One pair of wire-looping pliers and jewelers’ tweezers.
  • Skill Requirements:
    • Lapidary or Gemcutting: Rank 2 or higher.
    • Jewelry Crafting or Metalworking: Rank 2 or higher.
    • Esoteric Runecraft or Hermetic Alchemy: Rank 2 or higher.
  • Crafting Steps:
    • Mount the raw beryl nodule onto the dop stick using warm pitch, then grind the rough stone upon the lapidary wheel until it forms a balanced, hexagonal plum-bob tapering to a sharp, symmetrical downward point.
    • Polish each of the six hexagonal facets with diamond dust to achieve a smooth finish, ensuring the stone balances without favoring any lateral edge when suspended vertically.
    • Using the spirit lamp and blowpipe, draw the electrum ingot into a slender, uniform wire, subsequently cutting and looping the metal to form a flexible chain composed of exactly nine interlocked oval links.
    • Fashion a small conical electrum cap with a secure eyelet, affixing the cap firmly to the blunt upper apex of the shaped beryl utilizing heated pine resin and fine friction seating.
    • Carefully engrave the Hermetic sigils representing the sphere of Mercury and the elemental equilibrium of Air across the hexagonal facets of the beryl, using the diamond-point scribing burrs to cut shallow, contiguous grooves.
    • Crush the Tier 1 Magic Crystal into an impalpable powder within an agate mortar, sifting the particulate through fine silk to eliminate irregular shards.
    • Moisten the powdered magic crystal with the drops of mercurial distillate to create a conductive slurry, then rub the paste into the engraved sigil lines until every etched groove is filled flush with the facet surface.
    • Attach the nine-link electrum chain to the eyelet of the stone’s cap, then suspend the pendulum over the spirit burner for one minute while continuously chanting the Hermetic verses of telluric balance to anchor the resonant weave and solidify the magical conduit.

Green Stone Dropper and Merchant Who Had Double-Tongue

In the day-cycle of many moons past, when the sky-gas VaporSphere did sit fat and yellow like a spoiled melon over the water-reaches of Assyria, the speech-words of men were full of gravel and water-mud. In those season-times, the kings had big ears for honey-talk, and every market-man carried three sets of scale-stones in his wool belt: one stone for the brother, one stone for the stranger-man, and one stone that was hollow inside to take the silver without giving the barley.

There was a man of the river-wharf named Bar-Zabu. He had fat cheeks like a river-carp and seven large store-houses made of dried river mud. He was a seller of salt-fish and purple sheep-skins. When Bar-Zabu did open his mouth to make the trade-chant, his mouth did produce sweet water like ripe dates, but in his chest-room, his heart was like a dry iron hook. He would say to the boat-bringers: “Behold, these five jars of wine are full to the cork-top with the sweet blood of hill-grapes.” But the jars inside had three parts river-mud and four parts ditch-water, and the wine was only a thin red hat floating upon the top. By this method, he did gather many sacks of heavy gold coins, which he hid beneath the flagstones where his mother kept the baking pots.

It happened that upon a certain Divinday, an old walker of the Hermetic roads arrived at the city dock. His mantle was grey like goat hair that hath fallen into the hearth-ash, and he did not carry a staff or an iron knife, but held only a slender cord of white-gold wire upon which did dangle a pointed green pebble. The pebble had the form of a six-cornered turnip and was pale like young grass that hath not yet seen the star Helios. The city boys did cast dried mud-pies at his shins, thinking him an empty-head wanderer, but the pebble did not take the mud-stain; the mud did fall away like dry meal.

The wanderer sat upon an empty beer-keg before the counting-table of Bar-Zabu. He did say: “I seek three skins of dried mutton-meat to feed the fasting-mouths of the hill-lodge. But I have no round silver with the face of the Queen pressed thereon. I have only the truth-stone of the Air-House, which was shaped before the grand grandmother of Gaialilith did comb the mountains with her fingers.”

Bar-Zabu looked with laughing-eyes upon the old wanderer. He said: “Thou art a foolish grasshopper! Why should I give good salty sheep-flesh for a green cabbage-seed tied to a bit of silver wire? Yet, because I am a pious soul who loves the poor and honors the river-gods, I will trade with thee. Take these two baskets of dried fat-meat; they are the choicest back-pieces of prime highland rams, cured in the sun of Warming Week.”

Now, Bar-Zabu did lie with great boldness, for the baskets contained only the tough ears and the rotten tail-stumps of dead swamp-donkeys, seasoned with gray marsh-salt to hide the maggot-chew.

The wanderer did not touch the donkey-tails. He merely lifted his hand, holding the electrum wire by its ninth joint. He whispered seven strange words from the old tongue of the stars, words that sounded like: “Hermes… Thoth… Khem… make straight the plumb-cord of the world.”

The pale green stone ceased to hang loose. It began to fly in a smooth, quiet wheel, like a hawk turning over the grain field. It made no wind, but a noise came out of its pointed nose that sounded like a silver chime ringing across a frozen lake. Then did Bar-Zabu open his wide lips again to swear by the throne of the Queen that the meat was holy food for priests.

At that instant, the green stone did make a terrible leap in the air! It did not swing like a gentle water-bucket; it did jump sideways with a great snapping sound, like an adder-snake striking a boot-heel! A sharp smell of thunder-fire and roasted copper arose from the stone and did enter the nostrils of the people, so that the porters dropped their bales and sneezed with great violence. The braided chain did kick against the old man’s fingers, and across the six faces of the green pebble there ran lines of bright, angry fire that spelled out the true nature of the donkey-ears.

The wanderer did smile with his thin teeth and said: “Thy ram hath grown very long ears, O Bar-Zabu, and he brayeth when the cart is too heavy.”

The crowd of market-people did roar with red anger, for they had bought many such baskets in the previous moons. They seized the donkey-tails and did beat Bar-Zabu about his fat head until his turban fell into the horse-dung. But Bar-Zabu was a man of nimble thoughts and great wickedness. When the night-shadows fell and the wanderer lay asleep in the public wagon-yard, Bar-Zabu crept upon his bellies like a river-leech. He drew a sharp bone bodkin from his belt and cut the electrum cord, putting the green pendulum into his deep leather pocket. He thought to himself: “With this swinging eye, I shall go to the King’s palace. I shall stand behind the Grand Vizier and the ambassadors of the island nations. When they speak of their secret ships and their silver mines, I shall know where the gold is buried, and I shall become the master of the seventy-three lands!”

On the next morning, which was Enchanday, Bar-Zabu put on his finest coat of dyed blue linen and hung the emerald bob openly upon his chest, letting the green stone rest upon his thick belly. He walked into the Great Hall of the City Mayors, where a dispute was being held concerning the taxes of the wool-weavers.

The Head Mayor did look upon Bar-Zabu and said: “Why comest thou here, seller of fish? Didst thou pay the gate-silver to enter this assembly?”

Bar-Zabu bowed low and did lie with high ceremony: “O great father of the city, I have paid three silver coins to the guard at the south bridge, and I have come only to bring a free gift of honey to the scribes.”

He had not finished his lie when the green stone beneath his linen coat became cold—not like the cold of winter rain, but like the black ice that floats in the deep void beyond the gas giant. The cold was so terrible that it bit through his fat flesh into his ribs. Bar-Zabu gasped like a landed trout, but he could not stay his tongue, for he was a man accustomed to falsehood. He cried out: “And furthermore, my warehouses are entirely empty, and I have no grain to be taxed!”

With a sound like the cracking of a green cedar tree, the stone did violently snap upon its electrum tether! It did not merely wobble; it revolved with such fury that it tore through the blue linen garment like a wild badger. The green beryl began to strike Bar-Zabu upon the breastbone, over and over, with the force of a mason’s hammer, ringing with a shrieking, metallic brass tone that shook the dust from the ceiling rafters. At every strike, a cloud of acrid, bitter brimstone smoke erupted from his coat, filling the judgment hall with a stench so foul that the judges wept into their sleeves.

“He lies!” shouted the pendulum, not with mortal voice, but by vibrating the very teeth within the skulls of the listeners. “His mud-houses are full of stolen grain! His hearthstone is hollow! His salt is dirt! His soul is a broken pot!”

Bar-Zabu screamed and tried to tear the electrum chain from his neck, but the wire had knotted itself like cold wire-grass around his throat. He ran from the hall, screaming and leaping, while the green turnip pounded against his stomach like an angry goat, illuminating his fat body with flashes of fierce green and white fire for all the city to behold. The little boys chased him with sticks, and the market dogs barked at his smoking heels, until he reached the river embankment.

Being mad with the frost-burn on his chest and the shame of his revealed deceit, Bar-Zabu threw himself headlong into the swift, muddy currents of the river. The weight of the stone and the dense electrum links pulled his fat head down beneath the brown froth.

When the fishermen dragged their nets on the following morning, the body of Bar-Zabu was not found, for the mud-eels had made their dwelling in his garments. But caught in the hempen cords of the net was the pale green stone, hanging still and quiet from its nine electrum links. It did not shine; it did not smell of brimstone; it was cold and peaceful, waiting for a hand that knew the measurements of the heavenly spheres. The fishermen, knowing nothing of the high art of the lodges, traded it to an herb-woman for two measures of parsnips and an earthen dish of lard.

Moral of the Story: He who hangeth the plumb-line of truth upon his own crooked wall shall find that the weight doth not bend to suit the bricks; rather, the wall is beaten into gravel by the straightness of the stone.

Dungeons & Dragons (Fifth Edition)

Hermetic Emerald Pendulum Wondrous Item, Common (Requires Attunement)

  • Description: A pointed, hexagonal plum-bob carved from pale, clouded beryl suspended from a delicate nine-link electrum chain. The facet faces are etched with miniature Hermetic sigils corresponding to the sphere of Mercury and the elemental balance of Air. It measures subtle disturbances in local telluric currents caused by deceit.
  • Vibrational Chill (Passive): While wearing or carrying the pendulum against your skin, the stone grows noticeably cold whenever a creature within 10 feet of you knowingly speaks a deliberate falsehood. This property reveals only the presence of deception, not the identity of the deceiver or the specific untruth.
  • Caduceus Swing: As an action, you suspend the pendulum by its chain and whisper a brief Hermetic invocation of balance. For 1 minute, the pendulum swings in a smooth, rhythmic circle. When a creature you can see within 15 feet knowingly tells a lie, the pendulum violently wobbles and jerks off-axis, while emitting a quiet static crackle and a faint scent of ozone. Once used, this property cannot be used again until you finish a long rest.
  • Sealing of the Tongue: Over the course of 1 minute, you touch the pendulum to an unsealed document, contract, or ledger while reciting a formula of truth. The document remains protected for 1 hour. If any creature reading the document aloud or quoting it within 10 feet knowingly misquotes or misrepresents its contents, the paper emits a faint, acrid smell of burnt sulfur and singed copper. This property can be used once per day, regaining expended uses at dawn.

  • Description: An antique hexagonal beryl pendulum bound to a nine-segment electrum chain. The mineral faces bear micro-engravings matching the rituals of the Hermetic Order of the Golden Dawn, intended to align the investigator’s senses with telluric vibrations.
  • Powers and Mechanics:
    • Sense Falsehood: Whenever a subject knowingly lies directly to the carrier while the pendulum is worn touching the skin, the investigator receives an automatic Psychology check with a Bonus Die to notice that the speaker is being evasive or deceptive, accompanied by an intense cold sensation against the collarbone.
    • Rhythmic Verification: An investigator can spend 2 Magic Points and spend 1 full round holding the pendulum steady while asking a suspect a direct question. If the suspect fails an opposed Fast Talk or Charm roll against the investigator’s Occult or Psychology skill, the pendulum breaks its circular swing with an audible metallic chime and violent shudder, confirming the statement was a falsehood.
    • Parchment Binding: By spending 1 Magic Point and tracing the tip across an archival document, the user enchants the writing for 1 hour. Any individual who attempts to falsely state the contents of the page within the room triggers a noticeable, acrid whiff of burnt copper and ozone, exposing their duplicity to all present.

Fate (Fate Core / Condense)

The Caduceus Truth-Plumb Unique Extra / Personal Focus

  • Aspects:
    • Function Aspect: Resonant Hermetic Truth-Dowsing Pendulum
    • Flaw Aspect: Obvious Vibrational Telltale When Deception Breaks
  • Skills:
    • Grants an effective rating of Fair (+2) to Empathy exclusively when used to detect deliberate untruths, evaluate testimony, or discern hidden agendas in formal dialogue.
  • Stunts:
    • Chilling Telluric Whisper: While worn touching the skin, the bearer receives an immediate +2 bonus on passive Empathy checks to notice when a speaker is knowingly uttering a direct lie in their presence.
    • Caduceus Verification: Once per scene, when questioning a target in a calm environment, you may spend a Fate Point to suspend the pendulum and invoke the Hermetic balance rite. Create an advantage named Unmasked Falsehood with two free invokes on the target if they attempt to lie during the exchange.
    • Sealed Word Binding: By spending a Fate Point and touching the beryl tip to a physical contract or treaty, you place a temporary aspect on the paper: Sulfurous Seal of Veracity. If anyone knowingly misquotes or misrepresents the document’s terms aloud in the scene, the paper emits an undeniable puff of acrid sulfur, instantly revealing the deception to all observers.

Numenera & Cypher System

Telluric Resonator Bob Level 2 Cypher / Artifact (Depletion: 1 in 1d20)

  • Form: A palm-sized hexagonal plumb-bob of pale, crystalline mineral attached to a flexible chain of conductive, interwoven electrum wire. Miniature planar conduits etched into the facets glow dull green when attuned to ambient mental emanations.
  • Effect:
    • Deception Discord: While held in hand or worn against bare flesh, the artifact eases all tasks related to discerning lies, seeing through forged credentials, or detecting evasive speech by one step.
    • Harmonic Resonance Arc: When activated as an action, the user suspends the bob by its chain to initiate a steady circular swing that lasts for one minute. If an interlocutor within immediate range knowingly speaks a direct falsehood, the rhythmic motion abruptly fractures into a chaotic wobble, and the crystal emits a faint ozone burst. This effect eases the user’s next social or interrogation task against the speaker by two steps.
    • Document Inscription: The user can spend 1 point from their Intellect Pool to drag the pointed tip along the border of an inscribed document. For the next hour, if any creature within short range knowingly states a falsehood about the contents written upon that parchment, the ink flares bright red and releases an acrid odor of burnt mineral oil.

    • Frequency: Once per day
    • Effect: You trace the pointed tip of the beryl across a physical document or contract.

      • Caduceus Verification: Costs 1 Power Point. As an action requiring a brief occult chant, the user sets the stone swinging by its chain. For the next 3 rounds, whenever a targeted speaker within 3 paces tells an intentional untruth, the pendulum snaps into a violent, irregular stutter, automatically revealing the lie.
      • Sulfurous Seal: Costs 1 Power Point. The operator touches the pointed base to an open document. For the next hour, anyone attempting to deliberately misrepresent the written contents within 3 paces causes the paper to emit a pungent stench of burnt brimstone, inflicting a –2 penalty to that speaker’s social persuasion attempts for the remainder of the scene.

    • Caduceus Dowsing: The bearer can spend a Minor Action to suspend the bob, whispering a short ceremonial incantation. For 3 combat turns, if a questioned target within 5 meters knowingly lies, the steady circular swing violently hitches and emits an audible static snap. The user makes an Arcana + Logic test; achieving 2 or more hits completely exposes the deception and reveals whether the lie was spoken with malicious intent.

    • Physical Dowsing: Suspending the weight by its chain over a signed logbook or manifest and spending 10 minutes performing a calibration allows the user to make an Investigate check. Success reveals whether the author logged fraudulent coordinates, doctored transaction amounts, or falsified crew manifests.
