Vitreous Serpent Coil 771 – GearAscendancy.com

Lore This artifact is a dangerous, perfected fusion—a testament to sequential, unintended collaboration. The base of the item is the Ouroboros Ward 447, a symbiotic defense system from the Circle of Unmaking, designed to siphon ambient magic and unleash it as raw, chaotic punishment.

This volatile system was later discovered by a Pyreheart mage who, mistaking its nature, attempted to merge it with Blazevine and Firestone crystals, seeking to create the ultimate fire-channeling armor. The attempt failed catastrophically, fusing the fire magic directly into the Ward’s chaotic matrix and creating a relic of uncontrollable, self-destructive power.

Centuries later, the unstable artifact was found by a sage-winemaker from the Monastery of Clarity. She recognized that the system lacked control, not power. She performed a new ritual, merging her own relic, the Arm 221 of Revelatory Vintage, into the system. The Arm’s blessed vines and Dionysian resilience acted as a magical buffer, while its Quartz of Clarity became a focusing lens. The result, 771, is a single, symbiotic augment that integrates all three philosophies: the Ward’s retaliatory defense, the Flamewalker’s elemental fury, and the Arm’s wise, intoxicating clarity. It is a weapon that punishes, burns, and enlightens all at once.

Description The Vitreous Serpent-Coil 771 is a single, bio-magical armature that replaces a standard-sized avatar slot. It manifests as a series of twelve engraved silver nodules (from the Ward) that are surgically embedded along the wearer’s spine. These nodules are not cold; they pulse with a low, internal heat.

Living, supple vines of a deep burgundy leather-like texture (from the Arm) grow from these nodules, wrapping around the host’s torso and extending down one arm to form a full-length sleeve. A large, uncut quartz crystal (from the Arm) is set at the shoulder, but it no longer glows with simple light; a roaring, contained flame (from the Flamewalkers) now burns within it. The entire augment smells faintly of ozone, hot metal, and sweet, fermented wine. It is a single, integrated object that bonds permanently with the host.

Multiple Passives Magic

Vitreous Insight: The quartz crystal passively focuses the host’s mind. The wearer gains Advantage on all Insight checks to detect lies, illusions, or hidden intentions.
Ambient Siphon: The silver nodules along the spine passively draw trace amounts of magical energy from the environment, ensuring the Coil remains primed. This system generates 1 “Chaos-Charge” per hour (max 5). These charges are used to fuel its Active Magic.
Symbiotic Harmony: The Coil is a living system. The conductive filaments and vines will slowly self-repair over the course of several days if damaged.
Blazing Alacrity: The fused elemental power grants the wearer unnatural speed and grace. The wearer’s base movement speed is increased by 10 feet.

Multiple Active Magics

Retaliatory Pulse (Chaotic Wine):
- Trigger (Reaction): When the wearer is struck by a melee attack.
- Cost: 1 Chaos-Charge.
- Effect: The wearer automatically discharges a blast of intoxicating, chaotic energy at the attacker. The target must make a DC 18 Constitution saving throw.
  - Failure: The target takes 4d6 chaotic damage and is Stunned for 1 round, their mind overwhelmed by a conflicting flood of agonizing pain (from the Ward) and ecstatic joy (from the Arm).
  - Success: The target takes half damage and is not Stunned.
Flamestep Revelation:
- Trigger (Bonus Action): The wearer wills it.
- Cost: 2 Chaos-Charges.
- Effect: For 1 minute, the wearer’s movements become a fiery blur. They do not provoke attacks of opportunity, and they leave a trail of “Insightful Flames.” These flames are harmless to allies but force any enemy that starts its turn in or enters the flames to make a DC 18 Wisdom save.
  - Failure: The target is Charmed and Distracted for 1 round (as per the Arm’s Intoxicating Revelation).
Ouroboros Purge (The Unmaking Vintage):
- Trigger (Action): The wearer must physically grasp the quartz crystal on their shoulder, completing the Ouroboros circuit.
- Cost: 5 Chaos-Charges.
- Effect: The wearer vents the Coil’s entire stored energy. A violent, 30-foot-radius explosion of pure, purple-gold force erupts from the wearer. All other creatures in the radius must make a DC 18 Strength saving throw.
  - Failure: The target takes 10d8 chaotic-fire damage, is pushed 30 feet away, and any magical buffs (spells, potions) on them are immediately Dispelled.
  - Success: The target takes half damage and is not pushed or Dispelled.
- Backlash: After using this ability, the wearer is Stunned for 1 round as the psychic feedback of unmaking, revelry, and fire washes over them. The Coil’s Chaos-Charges drop to 0.

Item Durability and Repair

Item Hit Points

As a Tier 4 symbiotic artifact, the Vitreous Serpent-Coil 771 is fused directly with the host’s body. It cannot be “unequipped,” and targeting it is exceptionally difficult. An enemy must specifically declare they are targeting the Coil (such as the spinal nodules or the shoulder-mounted quartz) instead of the wearer, which would likely require a “called shot” at a significant penalty.

The Coil itself has 75 Item Hit Points.

If the Coil is reduced to 0 HP, its magic is disabled, not destroyed. The flame within the quartz extinguishes, the vines become brittle and lifeless, and the spinal nodules grow cold. The wearer immediately loses all passive and active benefits of the item. Furthermore, because the item is integrated with their nervous system, the wearer suffers a debilitating backlash, likely resulting in a severe, lingering debuff (such as paralysis or a massive penalty to all actions) until the item is repaired.

Repairing the Coil

Repairing a disabled Tier 4 symbiotic artifact is a legendary undertaking. This isn’t a job for the village tailor or a simple Mending cantrip; it requires a Master Artificer who is also specialized in bio-magical surgery.

The process would require three distinct components:

Host Stabilization: The wearer must first be medically stabilized by a Master Healer to survive the repair process.
Material Catalysts: Since the original items are fused, the repair requires new, potent catalysts that resonate with the three original “philosophies” of the item:
- A Source of Chaotic Warding: (e.g., The crystalline heart of a Shield Guardian or a flawless Chaos Emerald, as per the original Ouroboros Ward 447 schematic).
- A Source of Primal Fire: (e.g., A vial of molten lava from the Volcano of Eternal Ember or a cluster of 10+ Dragon Scale Fragments).
- A Source of Living Insight: (e.g., A new, uncut Quartz of Clarity and a flask of wine blessed by a harvest deity).
The Re-Fusion Ritual: The artificer must perform an incredibly dangerous, 24-hour surgical ritual. This would require passing a series of high-difficulty (Tier 4) skill checks in Magical Engineering (to re-route the magical circuits), Alchemy (to infuse the new catalysts), and Bio-Surgery (to re-integrate the living system without killing the host).

Failure during this ritual would be catastrophic. It would not only destroy the artifact permanently but would almost certainly cripple or kill the host.

Let’s be clear: you don’t “buy” the Vitreous Serpent-Coil 771. It isn’t “in stock.” You don’t add this to a “cart.”

A Tier 4 merged artifact is a singular, legendary item, and its acquisition is the finale of a major quest, not a shopping trip. If this item is ever “for sale,” it is almost certainly because its previous owner has just died, and the “item” is currently being surgically salvaged—or is still attached to—their corpse. The “shop” is merely the broker for this one-of-a-kind, high-risk procedure.

The following are the only three places such a transaction could possibly occur.

1. The Apex Auction House

Establishment: “The Sovereign’s Exchange.” This isn’t a shop; it’s a demi-plane, a floating city, or a magically-shielded fortress accessible only by invitation. It’s where national banks, arch-liches, and minor deities come to bid on items that can change the course of history.
Method of Sale: The Coil would be the centerpiece of a once-a-decade, “Black Invitation” auction. It would be displayed in a massive stasis-field, likely still gruesomely integrated into the spinal column of its former host. The auction price includes the non-negotiable services of the one-and-only Master Bio-Surgeon capable of performing the transfer. Bidding is silent, telepathic, and magically binding.
Estimated Cost: The starting bid would be 5,000,000 Gold Imperials. The final price would likely be double that, and probably not paid entirely in coin. The winning bid might be “4.5 million Imperials, the deed to the entire Andean archipelago, and the true name of a captured fire elemental.”

2. The Grandmaster Bio-Artificer’s Sanctum

Establishment: A place that is a quest in itself to find, known only as “The Suture-Sanctum.” It might be a mobile laboratory carved into the shell of a dimension-walking leviathan or a sterile, timeless vault at the bottom of a volcanic magma chamber. It is run by a singular, amoral genius who sees flesh and magic as interchangeable clay.
Method of Sale: This artificer likely salvaged the Coil themselves and views it as their greatest trophy. They have no interest in gold, which they consider a useless, soft metal. They are selling the procedure, and the item is just the “component.” They will only perform the integration if the buyer offers something of equivalent “interest.”
Estimated Cost:Barter Only. The price is something unique and irreplaceable. The artificer will demand payment like:
- “The original, un-augmented arm of a celestial.”
- “A complete, untranslated copy of Zharan’s Eclipsed Codex 821.”
- “The ‘memory’ of fire from a star that has died.”
- “A favor. Unspecified. To be called in at any time. Signed in blood.”

3. The Factional Reliquary

Establishment: The deepest, most secure vault of a major world power whose philosophy aligns with one of the Coil’s components—most likely the Monastery of Clarity.
Method of Sale: It is Not For Sale. It is a holy relic, an object of intense study and profound fear. It cannot be bought. It can only be bestowed. It would be granted to the single, proven champion of the order who is about to embark on a quest upon which the fate of the entire world (or at least the monastery) rests.
Estimated Cost: A Geas / Quest Reward. The “price” is completing an impossible task first (e.g., “Find and destroy the source of the Blazevine blight,” “Defeat the leader of the Circle of Unmaking”) and then swearing a magical, unbreakable oath to serve the monastery’s interests for life. The Coil is the ultimate “company car,” and the company owns your soul.

This item is less of a “tool” and more of a “walking catastrophe waiting to happen.” Its roleplay isn’t about if you’ll make a scene, but how big the explosion will be.

How it plays out…

1. In a Cramped Dungeon or Ruined Hallway

You are the ultimate “corridor-holder.” This is your ideal environment.

Defense: You are a wall of passive-aggressive pain. You don’t even need to use an action. You stand at the front and let the swarm of undead or cultists come to you.
- Roleplay: “The first zombie claws at you. You let it. As its fingernails screech against the living vines on your arm, your Retaliatory Pulse fires. A flash of purple-gold light, a smell of ozone and burnt wine. The zombie’s mind, simple as it is, is overloaded by the agonizing joy and it drops, stunned. The one behind it shoves it aside and bites. The Pulse fires again. You are a human bug-zapper, and every melee attacker is a bug.”
Offense: You are the “room-clearer.” When the hallway opens into a chamber filled with 20 goblins and a shaman, they all look at you.
- Roleplay: “They all charge, screaming. You sigh, grab the flaming quartz on your shoulder, and activate the Ouroboros Purge. This isn’t a fireball. It’s a 30-foot-radius detonation of pure, dispelling force. In this enclosed room, the shockwave slams every single creature into the stone walls, shattering their formation and extinguishing the shaman’s magical wards. The room is suddenly, violently silent… except for the ringing in your ears as you recover from the 1-round stun.”

2. On an Open Battlefield

You are an agent of chaos, a one-person shock-and-awe campaign.

Defense: A cavalry charge is coming. Normally, this is terrifying. For you, it’s an opportunity.
- Roleplay: “You stand your ground as the knights lower their lances. The first one hits you, a bone-shattering impact… and you trigger the Retaliatory Pulse on the horse. The 2,000-pound warbeast seizes up, stunned, and face-plants at a full gallop. The knight is thrown 30 feet, and the entire charge breaks apart as horses rear and panic at the blast of chaotic energy.”
Offense: You are the ultimate flanker. You need to get to the enemy commander, who is protected by a line of pikemen.
- Roleplay: “You activate Flamestep Revelation. The crystal on your shoulder blazes. You sprint. You’re a blur, moving 40 feet, and you don’t run around the pike-line, you run through it. You don’t provoke any attacks. You leave a trail of beautiful, mesmerizing fire. The hardened soldiers who try to turn and stop you are suddenly caught in its fumes, stopping to stare, charmed and confused. By the time they snap out of it, you’re already engaging the commander.”

3. In a Tense Social Situation (e.g., a Royal Court)

This is where you have to show restraint, which is hard for this item. You can’t use the Purge. But you have other, more terrifying tools.

Defense: The conniving duke is feeding the king a silver-tongued lie, and he has “proof” that implicates you.
- Roleplay: “You don’t say a word. You just watch the duke through the passive lens of your Vitreous Insight. You see the faint, sickly aura of his deception. You’re not guessing. You’re not rolling. The artifact shows you. When he finishes, you simply say, ‘He is lying.’ The king asks for your proof. ‘My proof is that I know his “evidence” is a forgery, his “witness” is paid, and his true intent is to seize the northern barony.’ The certainty with which you say it, backed by the artifact’s insight, is more compelling than any scroll.”
Offense: The guards move to arrest you based on the duke’s lies. You don’t want a bloodbath.
- Roleplay: “You activate Flamestep Revelation (cost: 2 Charges). You don’t run. You just take two slow, deliberate steps to the side, creating a ribbon of “Insightful Flames” between you and the guards. It’s not a wall of fire; it’s a shimmering, intoxicating haze. The guards who step into it stop dead, their hands on their swords, suddenly charmed and distracted by the beautiful patterns. ‘You don’t want to do this,’ you say, walking calmly past them toward the throne.”

4. In an Extreme Hazard (e.g., a Volcano)

This item makes you the king of the environment.

Defense: You’re in a magma-filled cavern.
- Roleplay: “The rest of the party is hopping across platforms. You just… walk. The lava flows around your legs, and you feel nothing but a pleasant warmth. Your Fire Immunity is total. You are walking across a lake of fire as if it’s a stepping-stone, much to the horror of the fire giants watching you.”
Offense: A group of Fire Elementals rises from the lava to stop you.
- Roleplay: “They are beings of pure flame. They hurl fireballs. You ignore them. They try to punch you. Every hit triggers a Retaliatory Pulse that stuns them. They are literally hurting themselves on you. Frustrated, they all charge at once. You grin, grab the quartz, and unleash the Ouroboros Purge. The 30-foot blast of chaotic-fire and dispelling energy doesn’t just hurt them—it unmakes them, extinguishing their magical forms and sending them screaming back to the Plane of Fire.”

Perception of Activation:

User’s Perspective (Avatar Wearing the Item):

Sight: The wearer’s vision sharpens to an unnatural, crystalline degree. The quartz on their shoulder ignites, visible in their peripheral vision as a roaring, internal furnace, casting flickering, fiery shadows. The vines on their arm pulse with a deep, purple-gold light.
Sound: A sudden, layered cacophony. It begins with a deep, vibrational hum from the spinal nodules, like a high-voltage transformer. This is immediately overlaid by the faint, bubbling sound of fermenting wine and the sharp, miniature roar of the contained flame in the shoulder crystal.
Touch: A three-stage sensation that hits at once. First, a powerful, tingling, vibrational energy courses up and down the spine. Second, a searing (but non-damaging) heat radiates from the shoulder crystal. Third, the burgundy vines wrapped around the arm and torso tighten slightly, feeling like a living, strengthening second skin.
Smell: A sharp, overwhelming, and contradictory scent: the sterile, electric tang of ozone, the acrid smell of superheated metal, and the sweet, heady aroma of fermented wine.
Taste: A powerful metallic tang of static electricity and copper, as if licking a battery, mixed with the cloying sweetness of hot, mulled wine.
Extra-Sensory (Vitreous Insight): The world snaps into agonizing focus. The quartz lens filters the wearer’s perception, revealing hidden intentions, lies, and emotional auras as stark, colored “threads” or “stains” in the air.
Extra-Sensory (Ambient Siphon): A sudden, greedy in-rush of power. The user feels the ambient magic of the area—ley lines, nearby enchantments, even the life force of plants—being vacuumed into the spinal nodules. It feels like a cold, hollow intake of breath.
Extra-Sensory (Chaotic Resonance): A conflicting, overwhelming psychic backlash. The user feels a flash of ecstatic, drunken joy (from the Arm) slammed against a feeling of pure, chaotic, retaliatory rage (from the Ward). This provides brief, fractured precognitive flashes but is deeply disorienting.

Observer’s Perspective (Those Nearby):

Sight: This is unmistakable and terrifying. The large quartz crystal on the wearer’s shoulder ignites like a miniature sun, casting a roaring, fiery light. The silver nodules visible along their back pulse with a violent, purple-gold light. Thin, crackling arcs of lightning jump between the nodules and along the deep burgundy vines.
Sound: A low, ominous, electric hum that rapidly rises in pitch to a sharp, painful shriek. This is coupled with the crackling of fire and a faint, wet bubbling sound, as if wine were boiling inside the armor.
Smell: The air around the wearer becomes thick with the smell of ozone, hot metal, and burnt, sugary wine.
Touch: The ambient air within 10 feet grows noticeably hot and dry. The static electricity is so strong it makes hair stand on end and teeth ache.
Extra-Sensory (Magical Sense): To any magic-user, this is a five-alarm fire. They perceive a sudden, massive “void” as the Coil siphons all available magic, followed immediately by the “scream” of a rapidly concentrating, unstable sphere of raw chaos, fire, and psionic energy. It’s not a spell; it’s a critical-state magical reactor about to breach.

Positives:

An overwhelming surge of absolute, god-like power.
Total environmental command, particularly a feeling of mastery over heat and fire.
Crystalline, supernatural focus from the Vitreous Insight; the ability to see truth.
A feeling of untouchable, retaliatory confidence. The wearer feels ready to be hit, knowing the punishment will be worse than the attack.

Negatives:

It is a sensory nightmare. The conflicting inputs (joy/rage, heat/static, wine/ozone) are deeply disorienting and can make concentration difficult.
Stealth is not just broken; it’s annihilated. The user is a walking beacon of light, sound, and magical energy.
The Vitreous Insight can be overwhelming—seeing the hidden ugliness, lies, and dark thoughts of every person in the room (including allies) is its own form of psychic damage.
The item wants to discharge. It takes active, physical effort to not unleash its power, making delicate tasks or simple, friendly contact (like a pat on the back) a high-risk gamble.

This isn’t so much a “recipe” as it is a schematic for a high-risk, borderline-insane surgical procedure. You are not “crafting” an item; you are “creating” a new, living, symbiotic being, and the “crafting table” is your host’s (or your own) body.

Proceed accordingly.

Schematic: The Vitreous Serpent-Coil Integration

Items Merged

Additional Materials Needed

1x Heart of a Living Magma Elemental: Required to serve as the new “forge” and power source for the fused artifact.
12x Vials of Purified Progenitor Ooze: A rare, symbiotic medium necessary to bind the disparate magical signatures to a living host’s nervous system.
1x Cask of 500-Year-Old “Sun-Blessed” Wine: Must be from a vintage blessed by a harvest deity. This will serve as the alchemical quenchant and psionic stabilizer for the final fusion.
50 yards of Spun Void-Spider Silk: A fiber capable of conducting both chaotic magic (from the Ward) and elemental fire (from the Flamewalkers) without melting.
1x Flawless, Fist-Sized Chaos Emerald: This will be consumed to catalyze the initial merger and provide the “charge-up” function.

Tools Required

A Master Bio-Surgeon’s Surgical Suite: Must be magically sterile and equipped for flesh-shaping and magical integration.
An Infernal Forge: A forge capable of safely containing and siphoning the energy from the Magma Elemental’s Heart.
A Bio-Weaver’s Loom: To weave the Void-Spider Silk with the living vines and conductive filaments.
A Grandmaster’s Alchemical Crucible: For refining the Progenitor Ooze and the Sun-Blessed Wine into a stable, symbiotic slurry.
A Magical Stasis-Field: To keep the host alive, unconscious, and magically stable during the multi-day procedure.

Skill Requirements

Grandmaster Artificer (Magical Engineering): To understand and rewrite the conflicting schematics of all three items.
Master Bio-Surgeon (Flesh-Shaping): To perform the actual, delicate, multi-day surgery without killing the host.
Master Alchemist: To create the symbiotic slurry and prevent the host’s body from rejecting the augment.
Master Enchanter: To bind the final, merged enchantments into the host’s aura.

Crafting Steps

Prepare the Core: The Heart of the Magma Elemental is placed in the Infernal Forge. The Scorching Flamewalkers (Blazevine, Dragon Scales, and all) are ritually fed into the forge. The Artificer and Enchanter must perform a 12-hour ritual to draw out and contain the conceptual essence of “Fire Immunity” and “Flamestep,” creating a single, white-hot ingot of “Vitreous Flame-Essence.”
Deconstruct and Fuse the Focus: The Arm 221 is carefully disassembled. The uncut Quartz Crystal is removed. The living, burgundy vines are separated and set aside. The Quartz is then taken to the Infernal Forge and plunged into the Vitreous Flame-Essence. The Artificer must precisely channel the energy, fusing the flame inside the crystal without shattering it.
Prepare the Armature: The Ouroboros Ward 447 is broken down. Its twelve silver nodules are polished and its conductive filaments are extracted. On the Bio-Weaver’s Loom, the Artificer weaves the Arm’s living vines, the Ward’s conductive filaments, and the Spun Void-Spider Silk into a single, cohesive, bio-magical armature. The 12 nodules are set along its length, and the newly-fused Flame-Quartz is mounted at the shoulder.
Prepare the Host (The Point of No Return): The host is placed within the Magical Stasis-Field. The Master Bio-Surgeon begins the 24-hour procedure of surgically implanting the 12 nodules along the host’s spine, weaving the new armature’s filaments directly into the host’s central nervous system.
The Alchemical Infusion: While the host is in surgery, the Master Alchemist takes the Chaos Emerald and grinds it to dust, blending it with the 12 Vials of Progenitor Ooze. This creates a highly volatile, shimmering, chaotic resin.
The Final Integration: The Bio-Surgeon uses this chaotic resin to “solder” the final connections between the armature and the host’s spine. The moment the circuit is complete, the entire stasis-field is flooded with the Cask of Sun-Blessed Wine.
The Awakening: The wine acts as a simultaneous coolant (for the fire), buffer (for the chaos), and psionic medium (for the insight). The Artificer must strike the main shoulder crystal, sending a magical shock through the entire system. This “reboots” the host’s body and the artifact as one single entity. The host must make a high-difficulty (Tier 4) Fortitude save.
- On a success, they awaken, and the Vitreous Serpent-Coil 771 is born.
- On a failure, the host’s body is incinerated from within, leaving only the artifact, now dangerously unstable and forever cursed.

Testament of Three-Become-One-Skin
(A transcription of glyphs found on a scorched, wine-stained stone tablet)

First, in the earth-before-time, there was the Still-Guardian. This was a creature, but not-living. Its job was a great sitting. The Old-Makers, who loved silence, gave this Guardian a magic skin. In the lists, it is the Ouroboros Ward (number 447). This skin was a thing of Saying-No.

If a loud-thing, a creature of wrong-motive, came, it would touch the Still-Guardian. The skin would then drink the magic in the air. The skin would shout this magic back. The loud-thing would be given a great pain, a chaotic-unmaking. The skin was a perfect No. It had no other thought.

Many suns, many rains. The Still-Guardian… it ended. It became dust. But the Skin of Saying-No (number 447) did not end. It waited in the quiet.

Then, a second man. A Man of Hot-Will. He was a fire-thinker. He found the Skin. He did not understand its No. He saw only its power. He had a great wrong-thought. He said, “This skin is only cold. It is only defense. I will make it offense. I will add the walking-fire.”

This Man of Hot-Will brought his own items. The fire-shoes. The (translation: Scorching Flamewalkers). These were made of dragon-skin and the blaze-vine. He built a hot-place, a forge. He tried to put-together the cold-chaos-skin with his hot-walking-magic.

This was a great error.

The forge-place made an explosion that was heard by the sky. The fire did not obey. The chaos did not sleep. They mixed. The Man of Hot-Will was… made-gone. He was eaten by his own making.

Now, the artifact was worse. It was not a Skin of Saying-No. It was a Skin of Screaming-Fire-Madness. It was a curse. It lay on the ground, burning, and shouting its chaotic fire at the sky, at the rocks, at the rain. It was too-much.

Many, many more suns. The earth turned. The Screaming-Fire-Madness-Skin was alone, for it ate all who touched it.

It was found by a third person. A Woman of the Wet-Joy (translation: wine) and Calm-Mind (translation: sage). She was from the (unknown symbol) Monastery of Clarity. She saw the artifact. It screamed at her. She did not run.

She looked. She listened. She put her hand on the burning, chaotic vines. It hurt. She did not pull away.

She said, (this part is poorly translated, intent is approximate): “You are a loud-child. You are a great shout with no head-thought. You are not a curse. You are just… unbalanced.”

She brought her own relic. It was the Sleeve of Good-Feeling (translation: Arm of Revelatory Vintage, number 221). This Sleeve was made of joy-vines from the grape-blood harvest. It had the stone-of-truth (the quartz crystal) that showed the inside of things. It was a sleeve of control and knowing.

She did not use a forge. She used a ritual. She used the sun-blessed wine and the Progenitor Ooze. She asked the items to become one.

The joy-vines of the Sleeve… they wrapped around the Screaming-Fire-Madness-Skin. They did not burn. They soothed. The stone-of-truth… it drank the fire. It did not break. It aimed the fire. The chaos-energy from the Skin of Saying-No… it became food for the fire. The fire from the hot-steps… it became light for the stone-of-truth.

The three became one. The (new word) Vitreous Serpent-Coil (number 771).

A Host-Man was found. A warrior. They did the great-pain-surgery. They put the Coil inside his back.

He woke.

He did not burn. He did not scream. He saw. He walked in fire. And when the loud-things came, he did not just say No. He answered. And his answer was a focused-fire-thought. And the loud-things were ended.

Moral of the Story: The Shout (Chaos) is only noise. The Heat (Power) is only burning. The Eye (Wisdom) is only seeing. But when the Shout, the Heat, and the Eye are made-one-skin… this is Purpose.
