History

Ancient Magic Inheritance

After Vera Black passes a bloodline trial in a void-like realm, an Ancient Magic crystal enters her body and forms a miniature Magic Circuit near her heart. Golden, web-like patterns briefly spread beneath her skin, while the crystal translates its information into a game-like interface she can understand. 1

The system immediately identifies Vera’s lower-body paralysis as repairable. Its stated solution, Life Reconstruction, requires the Circuit to reach Mastery · High-Tier and a mana reserve of at least 500. 1

Early Development

The Circuit’s first functions allow Vera to perceive magical traces, passively heal injuries, and rapidly analyze spell structure. Through residual magic left on training dummies, she unlocks Mana Tracing, recreates a memory of Diffindo, and learns to cast the spell without formal instruction. 5

Its progression system later confirms that spell practice, learning new spells, Ancient Magic use, and real combat all provide experience. Combat proves especially valuable after the Battle Resonance function unlocks. 6 14 22

Resonance with Hogwarts

Upon nearing Hogwarts, the Circuit responds strongly to the castle’s Ancient Magic. It perceives a vast network of runes embedded in the walls, identifies the systems governing moving staircases, and detects powerful magical sites within and beneath the castle. Wide-area sensing initially causes severe mental strain. 11 13

After Vera helps defeat the troll, Hogwarts grants the Circuit 10% Recognition, increasing magical recovery, casting speed, and magical power while she remains inside the castle. The Circuit later receives additional assistance from the castle, including accelerated recovery, Occlumency guidance, intrusion warnings, and the ability to conceal magical traces. 36 39 41 47 49

Appearance

The Magic Circuit has no independent physical body. Within Vera, it manifests through a small rhombus-shaped crystal near her heart, golden magical pathways beneath her skin, and translucent status messages visible on her retinas. 1

• Golden patterns first emerge from Vera’s scarred wrist and spread through her body during activation. 1
• The internal crystal acts as the core of the Circuit and produces its translated interface. 1
• The patterns can intensify or intertwine with blood-red runes after Vera acquires Source Flow Reforging. 26
• Vera’s compatible yew-and-Thestral wand bears golden spirals resembling the Circuit’s markings. 3

Abilities & Skills

Status Interface and Magical Augmentation

The Circuit presents Vera’s attributes, physical condition, mana reserves, talents, learned skills, and progression status. It also grants baseline improvements to spell power, mana recovery, and spell-learning speed. 1 25

• Initial bonuses are +20% basic spell power, +30% mana regeneration, and +50% spell-study speed. 1
• At Control · Beginner Rank, these become +30% basic spell power, +40% mana recovery speed, and +60% spell-learning speed. 25
• It tracks mana expenditure; ordinary early spells such as Diffindo consume roughly one mana, while Multicast adds five mana to the cost. 5

Circuit Vision

Circuit Vision allows Vera to see magical energy, residual spellwork, enchantments, curses, and magical structures that are normally invisible. 1 2

• It distinguishes protective enchantments and lingering spell traces in Diagon Alley. 2
• It reveals the magical network around Professor McGonagall’s Animagus form without alerting her. 12
• It exposes the runic mechanisms behind Hogwarts’ moving staircases and allows Vera to halt one by touching its controlling rune. 13
• It detects black fog associated with Quirrell and Voldemort, including trails spreading from the Forbidden Forest and Hogwarts’ underground areas. 30 31 32
• Broad or prolonged use overwhelms Vera, causing pain, exhaustion, and loss of concentration. 5 11

Basic Healing

A passive restorative function heals minor injuries and potion burns at visible speed. 1

• It completely removes Vera’s potion burn and heals cuts from flying dummy debris almost immediately. 1 5
• It does not resolve her paralysis or fully counter severe spinal pain caused by advanced Ancient Magic. 1 26

Mana Tracing

Unlocked while examining a Severing Charm trace, Mana Tracing reads intense magical residue and reconstructs fragments of the caster’s past actions. 5

• It lets Vera witness a previous caster using Diffindo and replicate the spell afterward. 5
• It can examine historical magic embedded in Hogwarts and the Room of Requirement, revealing visions of unknown Ancient Magic users. 25
• Reading too many traces at once places severe strain on Vera’s mind and body. 5

Spell Analysis and Reconstruction

By observing mana flow, the Circuit helps Vera understand, reproduce, and refine spells with unusual speed. 4 5

• Vera learns basic spells through magical retracing, including the Levitation Charm, Leg-Locker Curse, defensive spells, and every spell listed in The Standard Book of Spells, Grade 1. 7
• It provides precise awareness of mana output, wand angles, and spell pathways, allowing her to improve Diffindo from a shallow scratch to a dummy-destroying attack. 5
• Its analysis of magical control contributes to Vera’s immediate success in Transfiguration and Charms. 12 14

Magical Interference

When Vera can perceive a target’s magical structure and make physical contact while the target is off guard, the Circuit can briefly interfere with that target’s magic. 12

• Vera temporarily disrupts McGonagall’s Animagus form while petting her as a cat. 12
• The effect lasts only seconds and is impractical against alert opponents who would not allow close contact. 12

Multicast

Multicast is the first Ancient Magic learned through the Circuit’s Void Realm. 5

• At beginner level, it consumes 5 mana to apply up to two layers or overlapping instances of a spell. 5
• Vera uses it to cast two Diffindo attacks simultaneously, destroying a training dummy. 5
• At intermediate level, it can layer up to three effects on one spell or cast two different spells simultaneously with one spoken incantation. 25
• It allows Vera to combine effects such as levitating a target while silently cutting it apart, or casting a Petrification Spell while verbally casting another spell. 25 49

Battle Resonance

Battle Resonance activates after Vera’s first combat victory over Draco Malfoy. 14

• Victories grant 5 Resonance Value, while defeats grant 1. Every ten accumulated points triggers a combat enhancement. 14
• During combat, Resonance improves casting speed, magical power, and basic attributes. 14
• When battle ends, 20% of accumulated Resonance converts into maximum magical power and Magic Circuit experience. 14
• At 75 Resonance, the Circuit triggers Magical Burst, temporarily raising mana recovery and magical power by 75% for five minutes. 49

Magical Creature Taming

The Circuit can identify certain magical creatures as tameable and initiate a magical bond. 20

• It recognizes Fluffy as a tameable Three-Headed Dog. 20
• The listed reward for success is Circuit-level growth, +30 maximum magic power, and control over Fluffy. 20
• Vera forms an initial connection with Fluffy, but cannot fully tame it because its three heads possess separate consciousnesses. 20 21

Source Flow Reforging

Source Flow Reforging is a mana-intensive Ancient Magic acquired at beginner level. It infuses a selected body part with magic and grants it extraordinary temporary functions. 26

• Vera briefly restores sensation and strength to her legs, but collapses almost immediately; the spell is currently too weak to reliably restore function below her waist. 26
• Applying it to her right arm improves muscular strength, wrist stability, wand control, and spell precision. 26
• Continued use partially eases Vera’s spinal pain, though its relief remains limited. 30
• The ability consumes substantial mana and causes extreme pain during acquisition and use. 26

Hogwarts Recognition

The Circuit’s connection with Hogwarts grants location-specific benefits after Vera protects the school. 36

• At 10% Recognition, Vera receives +10% magical recovery, +10% casting speed, and +10% magical power within Hogwarts. 36
• Hogwarts can apparently restore Vera’s strength through its runes, though the exact conditions remain unclear. 39
• The castle guides Vera into the calm mental state needed to understand Occlumency. 41
• Through the connection, Vera can receive warnings of intruders and obscure magical traces after a battle. 47 49

Life Reconstruction

Life Reconstruction is the Circuit’s stated long-term solution to Vera’s paralysis. 1

• It requires Mastery · High-Tier Magic Circuit development and 500+ mana reserves. 1
• Vera has not yet met either requirement. 25 49

Limitations

• The Circuit’s mana reserve is finite, and intensive spellcasting or advanced Ancient Magic quickly exhausts Vera. 5 25 29
• Its functions are constrained by Vera’s frail body, weak hands, chronic pain, and lower-body paralysis. 25 26
• Advanced perception can cause headaches, physical weakness, and mental overload. 5 11
• Battle Resonance bonuses reset when a battle ends, leaving only the partial conversion into mana capacity and Circuit experience. 14
• Hogwarts Recognition benefits apply specifically within Hogwarts. 36

Relationships

• Vera Black — The Circuit’s inheritor and host; it resides near her heart, displays her status, and supports her pursuit of mobility and Ancient Magic mastery. 1 25
• Hogwarts — Its Ancient Magic network resonates with the Circuit, enabling recognition bonuses, magical guidance, warning functions, and trace concealment. 11 36 41 49
• Fluffy — Identified as a tameable magical creature; Vera establishes an incomplete bond through the Circuit. 20 21
• Peeves — Because Peeves is bound to Hogwarts’ magical structure, Vera uses the Circuit’s connection to the castle to restrain and bargain with him. 18
