Formal Classification: Auric-Cardiovascular Regulation Disorder
Common Name: Glass Heart
Codex Designation: Tier-Limiting Ki Circulatory Instability
First Recorded Instance: B.A rural lineage (confirmed post-factum)
Incidence Rate: <0.07% of recorded Earthborn ki users
Civil Classification: Medically acknowledged; socially ambiguous
Definition:
Glass Heart Syndrome is a rare and often misunderstood condition where the body’s ki distribution system and cardiovascular metabolism are misaligned, resulting in rapid burnout during sustained activity. Patients with GHS may demonstrate normal or above-average performance in brief exertions, only to experience sudden collapses, instability, or recovery lags shortly after.
The term "Glass Heart" refers symbolically to the central ki node, which behaves like a structurally resonant but fragile crystal—capable of brilliant expression, but prone to shattering if stressed beyond its natural rhythm.
Unlike external ki wounds, GHS is internal, invisible, and often goes unnoticed until the body fails.
What Glass Heart Syndrome Actually Does:
Glass Heart Syndrome isn’t just a matter of low stamina or poor health. It is a deep dysfunction in the synchronization between physical metabolism and ki channeling systems. To understand why patients collapse after brief output, we need to examine three internal systems:
In healthy individuals, the central ki node (sometimes called the aura-heart or core chamber) pulses rhythmically, like a second heart. This pulse drives ki circulation, adapting to the needs of the moment—gently during rest, intensely during combat.
In GHS patients:
The ki-core lacks adaptive feedback loops
It continues to pulse at maximum output once activated, with no internal dampening
As a result, too much energy leaves the core too quickly, destabilizing the aura and overloading downstream tissues
In a healthy body, ki energy and biological energy work in tandem—ki enhances oxygen uptake, accelerates cellular respiration, and allows for superhuman feats of endurance.
GHS disrupts this harmony:
Ki outpaces oxygen availability, leading to inefficient energy conversion
The body begins to pull anaerobic reserves too early, producing fatigue toxins
This creates a dual-burn effect—ki is drained, and the body’s real tissues exhaust themselves trying to keep up
In extreme cases or untrained GHS patients, the mismatch between internal strain and external projection leads to microdamage in the capillaries and ki-thread structures embedded throughout the body.
Symptoms include:
Minor internal bleeding, muscle fibril tears, or blurred vision during post-combat collapse
Disruption of aura-thread conduction, leading to trembling, delayed reflexes, or misfiring attacks
Long-term scarring in ki-reactive tissue if pushed too far repeatedly

KFS Tier Misalignment
Standard KFS testing often fails to detect GHS unless performed under stress-duration protocols. The syndrome can cause:
False Tier 1–2 readings due to erratic aura behavior
Spikes followed by collapse, which look like psychological instability
Missed red flags in rapid-fire proficiency drills
Many GHS patients pass Tier 2 fluency trials only to wash out of prolonged combat or ki-performance fields later.
Most GHS patients—especially those who are undiagnosed—develop complex psychological responses to conceal or control the effects:
Overcompensation through perfectionism, short-burst mastery, or hypercompetence
Aggressive self-image defense, reacting sharply to concern or pity
Withdrawal from group training, where their limits might be noticed
Rejection of help, fearing dependency will expose them
Some develop “masking disciplines”—personal martial or ki philosophies that disguise rest periods or aura compression as style.
There is no known cure, but medical and spiritual disciplines offer several stabilization techniques:
Natural suppressants that regulate pulse release from the ki core
Rare and location-specific; may vary by patient ancestry
Fighting styles based on “breathe-strike-reset” techniques
Designed to keep the patient under their collapse threshold
Psychological support to help patients accept power ceilings without shame
Introduced into high-school post-Year 190
An experimental method involving the use of low-frequency ki harmonics to strengthen aura conduits and prevent fracturing.
Administered in short sessions using ki-tuning chambers or focused resonance emitters
Must be calibrated to the patient’s ki signature to avoid overload
Results vary; sometimes improves aura cohesion, sometimes causes further destabilization
Still considered off-protocol in most Earth hospitals; currently restricted to medical academies or special-case recruits.
Custom-built clothing or armor infused with ki-regulating fibers that help moderate energy spikes in high-stress situations.
Typically worn by GHS patients who still operate in combat zones
Can absorb or buffer against sudden ki releases
May include biofeedback interfaces that alert the wearer before critical thresholds are reached
Seen as a controversial measure—useful, but seen by some as “crutch gear.”
Though Glass Heart Syndrome is formally classified as a circulatory ki disorder, some communities interpret it in more symbolic terms:
Forestline monks speak of those with GHS as “short-burn lives”—souls meant to shine briefly but brightly, often appearing in moments of great change.
In other spiritual groups, some refer to it as “Fractured Flow”, believing the body’s rhythm was never broken, only misaligned by the world's pace.
Among a few old martial sects, it is said:
“The blade that ends the fight is not the one that lingers.”
While these views are unofficial, medical instructors are trained to respect their influence, especially in patients from remote or traditional backgrounds.
