The Mechanics of "Room": Spatial Domination and Calculation.
The "Room" is a high-level mana-manipulation technique that allows a Mage to claim a specific volume of 3D space as their own. Unlike standard spells, a Room is a persistent mathematical field that overrides the natural laws of the environment.
I. The Core Rules of the Domain;
1. Exclusivity: A Mage cannot cast a Room if they are already inside an active one.
2. Sovereignty: Inside their own Room, the caster maintains 85% control over all ambient mana. Conversely, any opponent trapped inside suffers a 50% debuff to their mana control.
3. Containment: No being, except the caster, can exit the Room's boundary unless the caster explicitly wills it.
4. Counter-Measures: To counter a Room, one must either activate their own Room simultaneously or "crash" their own field into the opponent's to disrupt their calculations.
II. Visual and Structural Composition: a Room is the physical manifestation of a Mage's Star and their internal Coordinate System.
* The Graph Dome: The boundary appears as a translucent dome, tinted the color of the caster's Star.
* The Axis Stream: Glowing horizontal (X-axis) and vertical (Y-axis) lines stream around the curve of the dome like a rotating graph. These represent the active boundary calculations.
* The Z-Axis: A fixed, glowing grid appears on the floor of the dome, allowing the Mage to track the exact coordinates of every object within the radius.
* Scaling: A Room can be scaled from a 30m radius down to the size of a soccer ball. Smaller Rooms result in higher Mana Pressure and near-absolute control.
III. The Calculation Load, operating a Room requires the Star to process a constant stream of data:
* Boundary Equation: The Star solves for the surface area of the sphere, locking the mana frequency to those specific coordinates.
* Uniform Velocity: To track a moving opponent, the Mage must calculate the target's Velocity Vector ($\vec{v}$) and apply a Translation Transformation to the Room's center point in real-time.
* Mana Pressure: By "overclocking" the Star, a Mage can increase the density of the mana inside, creating a physical weight that stalls intruding Rooms.
IV. Combat Techniques: Filaments and Hacking: when two Rooms overlap, the battle shifts from power to Processing Speed.
* The Filament Method: A surgical strike where the Mage threads a razor-thin line of mana—no thicker than a hair—through the gaps in an opponent's Frequency. This allows the caster to trigger spells (like Ignition or Shock) deep within enemy territory.
* Frequency Shifting (Ghosting): A high-level defensive maneuver where a Mage tunes their Star to match the exact vibration and phase of an opponent's Room. This allows their dome to "phase" through the opponent's mana pressure without resistance, though it consumes 95% of their mental capacity.
* Coordinate Corruption: Using the overlap zone to send "calculation errors" into the opponent's Star, causing "system lag" and momentarily dropping their 85% control.
V. The Toll of the Grid: while casting a Room is relatively low-cost, maintaining it during high-speed combat is mentally draining. Constantly re-calculating the Z-axis for multiple moving targets while defending against intruding frequencies can lead to Neural Burnout. When a Room "shatters," it is often due to the caster's Star being unable to solve the incoming interference equations fast enough.
