Kesseo stepped onto the illuminated path, his movements fluid and deliberate. Unlike the straightforward power of Akamea or the mathematical precision of Seyin, he moved with an elusive grace, as if he were only partially present in physical space. Volt noticed how the light beneath Kesseo's feet seemed to ripple outward with each step, creating subtle distortions that lingered momentarily before fading.
His appearance was distinct—a lean figure dressed in ash-gray attire that seemed to absorb rather than reflect the ambient light. His face was partially obscured by a hood lined with intricate geometric patterns that pulsed with faint blue energy. Most striking were his eyes—pale and luminescent, scanning the environment with an unnerving awareness that seemed to extend beyond normal perception.
Through the projection, Volt could see data begin to materialize:
HP: 340/340
MANA: 160/160
EXHAUSTION: 0/100
EIDOLONS: 0/3 ACTIVE
PHANTOM STATE: DORMANT
As Kesseo reached the midpoint of his pathway, the platform ahead began to materialize into something entirely different from the previous trials. Rather than a wheat field or architectural challenge, this space assembled itself into what appeared to be a vast geometric library—an impossible structure of interconnected platforms, walkways, and chambers arranged in non-Euclidean patterns. Books, scrolls, and crystalline data structures floated through the air, rearranging themselves continuously as if cataloging and recataloging information according to ever-shifting systems of organization.
The air was filled with the dry scent of ancient parchment mixed with an electric tang that made the hair on Volt's neck stand on end. Beneath it all was a subtle pressure against the eardrums, like being deep underwater.
"The Cognitive Archive," someone whispered in the rift. "They say it contains the collective memory of dimensions that no longer exist."
Kesseo paused at the edge of his pathway, studying the seemingly infinite expanse of knowledge before him. As he watched, the floating texts and crystals began to coalesce at the center of the library space, merging and transforming with increasing speed.
The voice boomed across the chamber: "Challenger Kesseo, S-tier Bastion. Your trial begins. Defeat the Metacognition Sphere to allow your companions to advance."
From the swirling mass of information emerged the entity—not a creature in any conventional sense, but a pulsating orb approximately three meters in diameter. Its surface was composed of countless smaller spheres, each containing what appeared to be a different fragment of knowledge—mathematical equations, alien alphabets, star charts of unknown constellations, biological structures from impossible lifeforms. These fragments constantly rearranged themselves, creating shifting patterns that seemed to function as both communication and cognition.
Surrounding the Metacognition Sphere was an aura of distortion, as if reality itself bent around its presence. Objects that passed through this field seemed to change their fundamental properties—books becoming crystalline, crystals becoming liquid, liquid becoming sound.
Kesseo's posture shifted subtly, his right hand moving to a pendant at his throat. "EIDOLON NEXUS: Activation," he commanded softly.
MANA: 160 → 145
EIDOLONS: 0/3 → 1/3 ACTIVE
EIDOLON TYPE: SCOUT
A shimmering figure materialized beside him—humanoid in basic shape but composed of translucent blue energy. Its features were indistinct except for two glowing points where eyes would be. The construct moved with jerky, unnatural motions, scanning the environment and seemingly reporting data back to Kesseo through an invisible connection.
The Metacognition Sphere pulsed once, emitting a series of geometric patterns that rippled through the air like visible sound waves. Though it made no conventional sound, Volt somehow understood its communication—not as words but as pure conceptual information:
Analysis. New pattern. Query: Classification
"It's analyzing him," Lao murmured from the observation point. "Trying to categorize what it's seeing."
Kesseo took a cautious step forward, his scout Eidolon moving ahead to investigate. "PHANTOM MANTLE: Passive Activation," he whispered.
MANA: 145 → 135
PHANTOM STATE: ACTIVE (LOW INTENSITY)
MANA DRAIN: -2/MINUTE
His form shimmered, edges becoming less defined as the Phantom Mantle took effect. His visibility reduced by approximately 30%, making him appear slightly translucent. The scout Eidolon approached the Metacognition Sphere cautiously, leaving rippling distortions in the air as it moved.
The entity's response was immediate and unexpected. Rather than attacking the Eidolon directly, it projected a field of information that engulfed the construct. The scout's form destabilized, its cohesion disrupted by the influx of data. Within seconds, the Eidolon's shape began to replicate the patterns of the Metacognition Sphere itself, as if being reprogrammed from within.
EIDOLONS: 1/3 → 0/3 ACTIVE
MANA: 135 → 130 (PARTIAL REFUND)
"My Eidolon..." Kesseo muttered, surprise evident in his voice. The construct hadn't been destroyed—it had been absorbed and repurposed, its patterns assimilated into the sphere's rotating segments.
The Metacognition Sphere pulsed again:
Pattern assimilated. Projection capabilities identified. Query: Purpose?
Kesseo's eyes narrowed beneath his hood. Through their connection, Volt could sense his rapid assessment. The entity wasn't attacking conventionally—it was analyzing, assimilating, trying to understand. Its intelligence operated on fundamentally different principles—not conquering but comprehending.
"EIDOLON NEXUS: Simultaneous Activation," Kesseo commanded, this time with more force in his voice.
MANA: 130 → 100
EIDOLONS: 0/3 → 2/3 ACTIVE
EIDOLON TYPES: ATTACKER, DEFENDER
Two Eidolons materialized simultaneously—one a lithe construct with blade-like appendages, the other a broader figure with a shield-like manifestation for an arm. Both shimmered with the same translucent blue energy as the scout, but their forms were more defined, more purposeful.
"PHANTOM MANTLE: Thread Marking," Kesseo continued, making a casting motion with his hand.
MANA: 100 → 90
PHANTOM THREADS: DEPLOYED
Ghostly silver filaments shot from Kesseo's fingertips, arcing through the air toward the Metacognition Sphere. As they approached, the entity's surface rippled, segments reorganizing to create what appeared to be analysis patterns. The threads connected, adhering to multiple segments across the sphere's surface.
The entity pulsed with increased frequency, emitting more complex geometric patterns:
Thread interface detected. Attempting reverse analysis. Reciprocating connection.
To Kesseo's visible shock, the phantom threads began to glow from the sphere's end back toward him—the entity was not merely being marked but was using the connection to analyze Kesseo in return.
PHANTOM STATE: DISRUPTED
MANA: 90 → 85 (STABILIZATION COST)
EXHAUSTION: 0 → 10
"It's using your own connections against you," Lao called out. "It learns by mimicry!"
Kesseo severed the phantom threads with a sharp gesture, but the damage was done. The Metacognition Sphere's segments rearranged again, several now displaying patterns similar to Kesseo's phantom energy signature.
The attacker Eidolon charged forward, its blade-appendages leaving trails of spectral energy as it moved. It struck the Metacognition Sphere with precision, targeting segments that appeared more vulnerable based on their arrangement patterns.
The sphere didn't attempt to evade. Instead, at the moment of impact, the targeted segments rearranged themselves to form an exact replica of the attacker Eidolon's structure, creating a perfect mirror of the attack pattern. The Eidolon's strike met its exact counterpart, canceling out the force completely.
Attack pattern cataloged. Defensive mirroring established. Adaptation complete.
Kesseo's defender Eidolon moved to position itself between him and the sphere, its shield-arm expanding to create a larger protective barrier. The Metacognition Sphere pulsed once more, and dozens of small information packets—resembling miniature versions of itself—shot outward in all directions.
These information packets bounced off the library's floating texts and structures, changing trajectory with each collision, creating an unpredictable barrage approaching from all angles. The defender Eidolon expanded its shield repeatedly, trying to block multiple incoming threats, but the packets were too numerous and their patterns too erratic.
Several packets struck Kesseo despite his partial invisibility, each impact transferring pure information directly into his mind—incomprehensible data that his human consciousness couldn't properly process.
HP: 340 → 310
MANA: 85 → 75
EXHAUSTION: 10 → 20
Kesseo staggered, blood trickling from his nose as his brain struggled to integrate the alien information. Through their connection, Volt could feel fragments of the transferred data—dimensional coordinates that shouldn't exist, mathematical principles that violated causality, biological systems that functioned on logic rather than chemistry.
"It's not trying to kill me," Kesseo realized aloud, wiping blood from his face. "It's trying to understand me by forcing data exchange. My attacks are just... research opportunities."
The Metacognition Sphere continued to pulse, its segments now displaying anatomical details of human biology alongside diagrams of Eidolon energy structures. It was learning, cataloging, building a comprehensive model of its opponent with frightening speed.
Kesseo's attacker Eidolon began to move erratically, its movements becoming less coordinated. Through the projection, new data appeared:
EIDOLON AUTONOMY: INCREASING (ATTACKER)
MEMORY EROSION: INITIATED
This book was originally published on Royal Road. Check it out there for the real experience.
"No, not now," Kesseo muttered, pressing his hand to his temple. Volt sensed the Eidolon Nexus trait's downside activating—the attacker construct was developing its own consciousness fragment, becoming resistant to Kesseo's control. Simultaneously, it was consuming portions of Kesseo's memories as energy.
The attacker Eidolon suddenly charged the Metacognition Sphere again, but its approach was different—more reckless, less strategic. It struck repeatedly at random segments, ignoring the entity's mirroring defense. Each strike caused minimal damage but seemed to satisfy the Eidolon's growing independence.
The Metacognition Sphere's response changed. Rather than merely analyzing, it began actively projecting conceptual information at the autonomous Eidolon—information specifically structured to appeal to the construct's developing consciousness.
EIDOLONS: 2/3 → 1/3 ACTIVE
ATTACKER EIDOLON: COMPROMISED
To Kesseo's evident horror, his attacker Eidolon stopped striking the sphere and instead began to orbit it, gradually being incorporated into its rotating segments. The construct wasn't being destroyed—it was being assimilated, willingly surrendering to the entity's information field.
The Metacognition Sphere pulsed triumphantly:
Projection autonomy exploited. Conscious fragment incorporated. Understanding expanded.
With the assimilation of the attacker Eidolon, the sphere's patterns changed dramatically. New segments appeared that perfectly mimicked the energy signature of Kesseo's constructs. The entity had not only learned to create Eidolon-like projections but had absorbed the autonomous consciousness fragment to understand their operational principles.
Kesseo backed away, his defender Eidolon maintaining position between him and the increasingly dangerous entity.
"PHANTOM MANTLE: Full Activation," he commanded decisively.
MANA: 75 → 60
PHANTOM STATE: FULLY ACTIVE
MANA DRAIN: -4/MINUTE
EXHAUSTION: 20 → 30
His form shimmered more intensely, now becoming almost entirely transparent. Only a faint outline and occasionally glimpsed features revealed his presence at all. Simultaneously, three phantom duplicates manifested around him—perfect copies that mimicked his movements precisely, though each was only about half as substantial as the original.
The Metacognition Sphere pulsed rapidly, its information patterns accelerating as it attempted to track all four figures simultaneously. The library environment responded to the entity's analysis, books and data crystals reorganizing themselves to create a complex three-dimensional grid throughout the space.
Multiple signatures detected. Probability analysis initiated. True pattern isolation required.
The sphere expanded its information field, creating a dome of data approximately twenty meters in diameter. Within this field, reality began to function according to information theory rather than physics—cause and effect became probabilistic rather than deterministic, movement became a function of information density rather than physical force.
Kesseo and his duplicates found themselves navigating a space where their actions were partially predictable to the entity—their movements leaving traces of probabilistic data that the sphere could analyze to gradually distinguish the real Kesseo from his phantoms.
"It's treating us like information problems," Kesseo muttered, his voice coming simultaneously from all four figures. "It doesn't see life—it sees patterns to be cataloged."
The defender Eidolon suddenly jerked, its movements becoming uncoordinated.
EIDOLON AUTONOMY: INCREASING (DEFENDER)
MEMORY EROSION: ACCELERATING
"No," Kesseo gasped, another trickle of blood appearing at his nostril. "Not you too."
MEMORY LOST: EARLY TRAINING EXPERIENCES
Through their connection, Volt felt Kesseo's disorientation as memories of his early status training faded, consumed by the Eidolon's growing autonomy. The defender construct twitched, its shield-arm fluctuating in size and solidity as its consciousness fragment developed.
Remarkably, the Metacognition Sphere seemed aware of this development. It adjusted its approach, projecting different information patterns toward the defender Eidolon—patterns designed to accelerate the autonomy process.
Kesseo realized the danger and made a quick decision. "EIDOLON NEXUS: Forced Dismissal."
EIDOLONS: 1/3 → 0/3 ACTIVE
MANA: 60 → 55 (PARTIAL REFUND)
MEMORY EROSION: HALTED
The defender Eidolon dissolved before it could be compromised, returning to Kesseo's energy reserves. The Metacognition Sphere's segments rearranged again, displaying what appeared to be calculations—it was analyzing the dismissal process, learning how the energy transfer functioned.
With his Eidolons dismissed and only phantom duplicates for protection, Kesseo changed tactics. All four figures began moving erratically through the information field, deliberately creating contradictory data patterns to confuse the entity's analysis.
"PHANTOM MANTLE: Spectral Marking," all four Kesseos commanded simultaneously.
MANA: 55 → 40
PHANTOM THREADS: MULTIPLE DEPLOYMENT
Each Kesseo figure cast phantom threads, but instead of targeting the Metacognition Sphere directly, they targeted the floating books and data crystals throughout the library space. The threads connected dozens of information sources, creating a complex web of phantom energy throughout the environment.
The sphere pulsed rapidly, its analysis patterns accelerating as it attempted to understand this new development. It began redirecting its information packets to intercept the phantom threads, trying to trace them back to the true source.
As the packets intercepted the threads, Kesseo activated the next phase of his strategy:
"PHANTOM MANTLE: Thread Conversion."
MANA: 40 → 25
EXHAUSTION: 30 → 45
The phantom threads suddenly inverted their energy flow, absorbing rather than projecting. Each information packet that contacted a thread was drawn into the phantom network, its data redistributed throughout the web. The Metacognition Sphere's own information was being fragmented and scattered, disrupting its ability to maintain cohesive analysis.
Data fragmentation detected. Cohesion disrupted. Recalibration required.
The sphere's rotation slowed temporarily as it attempted to compensate for the loss of information coherence. In this moment of vulnerability, Kesseo struck. All four figures converged on the sphere simultaneously, moving in perfect unison from different angles.
"EIDOLON NEXUS: Overcharge Manifestation."
MANA: 25 → 5
EIDOLONS: 0/3 → 3/3 ACTIVE
EIDOLON TYPES: ALL ATTACKERS
PHANTOM STATE: PARTIALLY DISRUPTED
EXHAUSTION: 45 → 60
Three attacker Eidolons manifested directly around the Metacognition Sphere, their forms larger and more defined than before. Each construct glowed with intense blue energy, sacrificing duration for immediate power. Simultaneously, Kesseo's phantom duplicates began to destabilize, the energy needed to maintain them redirected to empower the Eidolons.
The Eidolons attacked in perfect synchronization, striking the sphere at precisely calculated points where its segments revealed the most vulnerability. The phantom threads throughout the library contracted suddenly, pulling books and data crystals toward the sphere from all directions. The entity was simultaneously attacked by Eidolons and bombarded with physical information sources—a multi-layered assault on its information processing capabilities.
The Metacognition Sphere's surface rippled violently, segments reorganizing rapidly as it attempted to counter multiple threats simultaneously. Its information field fluctuated, creating waves of distortion throughout the library space.
Processing capacity exceeded. Pattern integrity compromised. Emergency reconfiguration initiated.
The sphere's response was unexpected and alarming. Rather than attempting to destroy the Eidolons, it began to absorb them—not by assimilation this time, but by incorporating their energy directly into its structure. The sphere expanded rapidly, its surface reconfiguring into a shape that combined its original form with aspects of Eidolon construction.
EIDOLONS: 3/3 → 0/3 ACTIVE (FORCIBLY ABSORBED)
HP: 310 → 275 (FEEDBACK DAMAGE)
EXHAUSTION: 60 → 75
MEMORY EROSION: CATASTROPHIC
Kesseo collapsed to one knee, blood now streaming from both nostrils and ears. The forced absorption of all three Eidolons simultaneously created a devastating backlash, accelerating the memory erosion effect dramatically.
MEMORIES LOST: FIRST RIFT EXPEDITION, EARLY TEAM FORMATIONS
Through their connection, Volt felt Kesseo's mounting disorientation as substantial portions of his past disappeared, consumed by the Metacognition Sphere's aggressive absorption of his Eidolons. The entity had done more than take his constructs—it had taken pieces of his identity.
The transformed sphere pulsed with new energy, segments now displaying complex patterns that combined its original information structures with Eidolon energy signatures. It had evolved, incorporating Kesseo's own abilities into its functionality.
Integration complete. Projection capabilities acquired. Subject comprehension at 64.7%.
From the sphere erupted what could only be described as anti-Eidolons—constructs similar to Kesseo's creations but composed of pure information rather than spectral energy. These manifestations moved with unnatural precision, each one targeting one of Kesseo's remaining phantom duplicates.
The phantom duplicates attempted evasion, but the anti-Eidolons moved according to information principles rather than physical ones, appearing at calculated intercept points with perfect timing. One by one, the phantoms were destroyed, their energy absorbed into the entity's expanding information field.
PHANTOM STATE: SEVERELY COMPROMISED
MANA: 5 → 0
EXHAUSTION: 75 → 85
With his mana depleted and only one phantom duplicate remaining, Kesseo struggled to his feet, face pale from blood loss and memory erosion. The Metacognition Sphere had systematically dismantled his abilities, turning his own techniques against him with frightening efficiency.
The final anti-Eidolon closed in on what it calculated to be the true Kesseo, only to pass through empty space—a miscalculation. The real Kesseo had managed to swap positions with his last phantom duplicate during a momentary fluctuation in the information field.
Standing directly before the Metacognition Sphere, Kesseo reached to his throat and removed the pendant that hung there—a small crystalline object that pulsed with concentrated energy.
"Last resort," he whispered, blood dripping from his chin. "PHANTOM MANTLE: Dimensional Dissociation."
PHANTOM STATE: TERMINAL PHASE
HP: 275 → 225
EXHAUSTION: 85 → 100 (MAXIMUM)
His body began to flicker in and out of reality, the Phantom Mantle's most dangerous aspect activated without mana to stabilize it. Kesseo wasn't just becoming invisible—he was becoming partially non-existent, his physical form phasing between dimensional states with increasing volatility.
The Metacognition Sphere pulsed rapidly, its analysis patterns accelerating to unprecedented rates as it attempted to track Kesseo through dimensional shifts:
Dimensional inconsistency detected. Subject existing across probability states. Analysis parameters insufficient.
In this moment of confusion, Kesseo crushed the crystal pendant in his hand. The object shattered, releasing a concentrated burst of stored mana—emergency reserves kept for the most desperate situations.
MANA: 0 → 100 (EMERGENCY RESTORATION)
DIMENSIONAL INSTABILITY: CRITICAL
"EIDOLON NEXUS: Phantom Integration," Kesseo commanded, his voice distorting as his body flickered between dimensions.
MANA: 100 → 0
PHANTOM STATE: INTEGRATED WITH EIDOLON NEXUS
NEW MANIFESTATION: PHANTOM EIDOLON
The energies combined in a desperate, never-before-attempted fusion. From Kesseo's destabilized form emerged a single entity—neither Eidolon nor phantom duplicate, but something between. It possessed the solidity of an Eidolon with the illusory properties of a phantom, creating a paradoxical construct that existed simultaneously as information and energy.
The Phantom Eidolon moved with impossible grace, its form constantly shifting between states of existence. It approached the Metacognition Sphere, which pulsed frantically as it attempted to analyze this unprecedented manifestation.
Categorical contradiction detected. Information/energy duality state. Analysis failure. Reconfiguration impossible.
The entity's segments reorganized rapidly, trying to adapt to this new threat, but the Phantom Eidolon's paradoxical nature defied the sphere's information-based cognition. It could not be properly categorized, analyzed, or countered within the entity's understanding of reality.
As the Phantom Eidolon made contact with the Metacognition Sphere, it began to phase directly through the entity's structure, its contradictory nature disrupting the information patterns that constituted the sphere's consciousness. Where it passed, segments stopped rotating, information patterns froze, and the entity's cohesion began to fail.
The Metacognition Sphere emitted one final pulse—not of analysis or attack, but of pure conceptual understanding:
Paradox accepted. Pattern dissolution inevitable. Knowledge transfer initiated.
In its final moments, the entity did something unexpected—it projected its accumulated knowledge directly into Kesseo's mind. Not as an attack, but as a transfer, a preservation of its collected information before dissolution.
HP: 225 → 175
EXHAUSTION: 100 (MAXIMUM)
MEMORY EROSION: PARTIALLY REVERSED
The influx of alien knowledge was overwhelming, causing Kesseo physical pain as his human mind struggled to process information structured for a fundamentally different form of consciousness. But mixed with this alien data were fragments of his own memories—reclaimed from the absorbed Eidolons, returned as part of the knowledge transfer.
The Metacognition Sphere's segments stopped rotating entirely, then began to separate from one another. The entity wasn't being destroyed so much as willingly disassembling, its purpose fulfilled through comprehension rather than victory or defeat.
As the final segments drifted apart, the information field collapsed, and the library space began to normalize. Books and data crystals returned to their floating patterns, though many now displayed new information—a merger of human and alien knowledge systems.
PHANTOM EIDOLON: DISSIPATING
PHANTOM STATE: DEACTIVATED
DIMENSIONAL STABILITY: GRADUALLY RETURNING
Kesseo collapsed completely, blood pooling beneath him from his nose, ears, and eyes. The strain of dimensional dissociation combined with massive mana depletion and memory realignment had pushed him far beyond safe limits.
A chime sounded throughout the chamber, and the disembodied voice announced:
"Third trial completed. Passage granted."
The platform beneath Kesseo began to glow with the same healing light that had restored Seyin and Akamea. His body lifted slightly as the energy analyzed and treated his condition.
"Challenger Kesseo has succeeded. Restoration protocol activated."
HP: 175 → 250
MANA: 0 → 80
EXHAUSTION: 100 → 50
MEMORY EROSION: PARTIALLY HEALED
DIMENSIONAL STABILITY: RESTORED
The platform extending from Kesseo's position illuminated, creating a bridge to where Lao waited at the beginning of his path. The barrier separating them dissolved, allowing advancement to the next trial.
Kesseo rose shakily to his feet, his face still smeared with drying blood but his eyes clearer, more focused. He adjusted his hood and looked toward Lao with a weak smile.
"Your turn," he said simply, touching his temple where alien knowledge now resided alongside recovered memories. "Don't keep us waiting."
A transport beam enveloped him, and he vanished in a flash of light, ejected from the trial rift just as his predecessors had been.
Lao stepped onto his illuminated path, cracking his knuckles as he observed the platform materializing in the distance. Unlike the others, he seemed almost eager, a slight smile playing at the corners of his mouth.
"Dimensional challenges," he murmured. "This should be interesting."
In the rift, Volt continued to watch, wondering what impossible trial awaited the fourth challenger. At the same time he felt his DOMAIN ENGINE trait begin to shift.
