The Path of the Star: A Guide to Magic and Calculation
In a world reshaped by Gates, magic is not a "gift"—it is a mental achievement. While many are born with a sensitivity to mana, only those with the discipline to forge their own Star can truly call themselves Mages.
I. The Genesis: The Mana-Resonant Cortex
Since the appearance of the Gates, the human brain has undergone a biological shift. A dormant sector of the brain, enhanced by generations of exposure to high-density mana, now serves as the foundation for magic.
* Respiration: Potential mages must dwell in high-mana zones, "filtering" the energy through their lungs and into their bloodstream.
* The Forge: Through deep meditation, this mana is forced into the brain's "hidden sector," eventually crystallizing into a Star.
II. The Star: A Personal Processor
The Star is a man-made biological receptor. No two Stars are identical, as they are physical manifestations of the mage's psyche.
* Aesthetic Identity: A Star's color, shape, and size are unique to the mage. One might have a jagged, obsidian star pulsing with violet light, while another might have a perfect, golden sphere that hums like a tuning fork.
* Function: The Star translates human brain waves into Mana Waves, commanding the surrounding environment to rewrite the laws of physics according to the mage's intent.
III. The Art of Calculation (The Software)
To cast a spell is to solve a high-speed equation. The Star provides the connection, but the Mage must provide the Logic.
* Variables: A mage must calculate mass, velocity, atmospheric pressure, and mana-density in real-time.
* The Staff: Used as a stabilizing Output Medium, the staff acts as an external processor that prevents "Packet Loss"—ensuring the calculation doesn't fail midway and cause a mana backflow (Neural Burnout).
IV. Original Spells: Formula & Creativity
Standard spells are like using a pre-written calculator app. Original Magic, however, is like writing the entire operating system from scratch.
* Derivation: A mage derives their own unique formula to reach a specific result (e.g., Mira's Recoil).
* The Creative Spark: It is not just about math; it is about imagination. A mage must "visualize" a phenomenon that doesn't exist in nature, then use their Star to calculate the bridge between that imagination and reality.
* Unpredictability: Because the formula is private and unique, Original Magic is nearly impossible for enemies to calculate a counter-measure for.
V. The Danger: Neural Feedback
The brain is a biological organ, not a machine.
* Overclocking: Attempting a calculation beyond one's processing power or miscalculating a decimal point can lead to Neural Feedback.
* Symptoms: This ranges from simple nosebleeds and migraines to the literal "shattering" of the Star, which results in permanent brain damage or the loss of magical ability.
VI. The Threshold: Mana Sensitivity
The "Path of the Star" is not open to everyone. While the biological structures exist in most modern humans, the ability to utilize them depends entirely on an individual's Mana Sensitivity.
* The Barrier of Entry: Those with low sensitivity are effectively "deaf" to the mana around them. No matter how much they meditate or breathe in high-density mana, they cannot gather enough energy to trigger the "Crystallization" of a Star.
* The "Dim" Stars: Some individuals with borderline sensitivity manage to forge a Star through sheer willpower, but the result is often small, unstable, or "dim." These mages struggle with the most basic calculations, and their output is significantly capped.
* The Non-Lethal Class: Mages with weak sensitivity often find their spells lack the "mass" to be effective in combat. Their magic is relegated to utility or domestic tasks—creating a small spark instead of a fireball, or a light breeze instead of a Gale Blade. In the world of high-ranking Hunters, they are invisible.
VII. The Hierarchy of Talent
This creates a clear divide in the magical society:
1. The High-Sensitives: Natural geniuses like Mira, whose brains can "hear" the mana perfectly, allowing for the construction of complex, vibrant Stars and high-speed "Original" formulas.
2. The Low-Sensitives: The tragic majority who either fail the path entirely or live as "Second-Class Mages," unable to produce lethal force regardless of how good they are at math.
Side note: by this information, during the first appearances of gates, mages hadn't existed then. Simply because the mana hadn't properly mutated the part of the brain that ended up becoming the "Mana-Resonant Cortex". Mages down the line gradually had become more sensitive to mana allowing the mage profession to be realised after 400a.g(after gates).
