The Power Source: Ambient Threads
Magic does not exist inside people; it exists in the environment.
Threads: Ambient magical energy floats invisibly in the atmosphere as tangible "Threads."Frequencies: Every Thread has a specific elemental property and an exact vibration rate. An Ignis Thread contains heat. A water-based Thread glows luminescent blue. A low-tier kinetic Thread vibrates like a taut piano wire at exactly four hundred hertz.
The Standard Mechanic: Internal Anchoring
This is the standard methodology utilized by the nobility and Academy students.
The Draw: A Weaver casts their awareness into the room, locates a specific Thread, and physically pulls that raw energy into their chest.
The Engine (The Node): The energy anchors to a spiritual node located directly behind the sternum. Processing this power causes the Weaver's chest to illuminate with pale light. The human body acts as the vessel, safely housing the volatile energy.
The Projection: Once anchored, the human mind shapes the energy and weaponizes it, projecting it outward through the palms.
The Failsafe: The human body acts as a biological crucible. Drawing too much power overloads the system, triggering a biological safety valve that simply causes the Weaver to faint before they can blow themselves up.
Skill/Efficiency: Posture and stance matter. Sloppy form causes the Weaver to leak kinetic potential, wasting up to thirty percent of the spell's raw power.
The Defect: Zero Resonance
If a person is born with a fractured node (a "ruined splinter"), they are a broken vessel.
The Consequence: Dragging a Thread into a broken node causes the nervous system to boil. The biology violently rejects the resonance, snapping the Thread and shredding internal organs from the inside out. It produces zero magical output and results in agonizing physical trauma.
The Biological Dead Zone (The Stealth Advantage): Standard magical wards and perimeter alarms operate by tracking the internal resonance or "mana signature" of a Weaver. Because a fractured node produces no signature, the individual's core is a biological dead zone. They register as empty air to magical security systems, allowing them to walk completely undetected through layered wards that would instantly trigger for any normal mage.
The Workaround: External Anchoring (First Era Deviations)
This is an ancient, highly forbidden method of casting that predates the Academy.
The Bypass: Instead of pulling a Thread into the chest, the Weaver grabs the raw power and shoves it downward into an external physical object, such as a glass or obsidian sphere.
The Mechanics: The Weaver must mentally suffocate the Thread, clamping down on its frequency until its wavelength perfectly matches the density of the physical stone. This stabilizes the volatile energy inside the glass boundary.
The Projection: Releasing a sliver of willpower snaps the makeshift containment ward open. The mismatched resonance shatters the physical conduit, creating a massive, localized detonation.
The Output: Because the spell is not limited by the human body's biological safety valves, the sheer concussive output dwarfs a standard student cast by a factor of three. Limitations, Costs, and Weaknesses
External Anchoring carries brutal physical risks and strict limitations.
The Calculation Bottleneck: Stones do not have biological failsafes. The Weaver must manually calculate the exact vibration frequency of the Thread against the atomic density and mass of the conduit. Dividing mass by the density quotient requires intense focus. A single rounding error causes a catastrophic misfire, resulting in missing limbs or death. Calculating this math mid-battle while dodging enemy fire requires absolute concentration.
The Ammunition Economy: Standard Weavers cast until their physical stamina runs out. External Weavers require physical conduits. Projecting the spell shatters the stone. Bringing five obsidian spheres to a fight means the Weaver only has five spells. Furthermore, glass and obsidian cost money. Poverty directly caps a Weaver's magical arsenal.
The Physics of Friendly Fire: Detonating a spell completely outside the body removes the protective buffer of an internal node. The caster is subject to real-world physics. Concussive force explodes outward in all directions. Setting off a kinetic shockwave vaporizes the target, but the backlash also hits the caster. Getting thrown backward, suffering bruised ribs, and enduring ringing ears are the standard physical traumas of casting. Tactical positioning is mandatory to survive one's own spells.
The Preparation Phase: Doing complex physics equations on the fly is highly dangerous. A Weaver utilizing this method must pre-calculate the density of specific stones and memorize the math equations before a fight ever breaks out.
