1. Cassian Valerius :
Age: 15 (First-Year).
Mana Type: None (Null). Internally, he hosts the Void-Core, an anomaly that deletes energy rather than producing it.
Appearance: Pale, perpetually tired-looking with dark circles under his eyes. Currently using the Fragility Draught to look sickly and Void-Skin to mimic shattered veins.
Personality: Calm, cynical, and highly efficient. He values sleep and silence above all else. He isn't interested in being a hero; he just wants to be left alone, but he will systematically dismantle anyone who threatens his "quiet life."
2. Elara Valerius(Twin Sister):
Age: 15 (First-Year).
Mana Type: Silver-Light (High Density). Her mana is crystalline and pure, representing the peak of the Valerius bloodline.
Appearance: Sharp, regal features with eyes that glow faintly silver when she's focused. She is the visual opposite of Cassian—radiant, disciplined, and alert.
Personality: Proud, intensely disciplined, and protective yet suspicious. She was raised to be the family's pride, but her twin bond makes her the only one capable of sensing the "unnatural" emptiness where Cassian's mana should be.
3. Lyra Thorne:
Role: Ally, Strategist & Logistics Expert.
Age: 15 (First-Year).
Mana Type: Low-Tier Earth/Utility. Her mana is insufficient for high-level combat, making her an "invisible" student in the Academy.
Appearance: Often found in the background, wearing oversized merchant-style robes with pockets full of vials, scrolls, and illegal Academy blueprints.
Personality: Pragmatic, ambitious, and fiercely loyal. She is a social outcast who realized early on that Cassian is a "monster" she can work with. She provides the brains and resources for his cover stories.
4. Princess Aurelia :
Role: 3rd Princess of the Empire & Student Council President.
Age: 17 (Third-Year).
Mana Type: Golden Solar / Royal Decree. Her mana has a "command" property that can physically suppress or "order" the energy of lower-ranked mages.
Appearance: Impeccably dressed in royal silks layered over the Academy uniform. She carries an aura of absolute authority that forces people to bow without realizing it.
Personality: Cold, calculating, and politically brilliant. She views the Academy as a microcosm of the Empire. She doesn't care if Cassian is a hero or a dud; she only cares if he is a variable she can control.
5. Raiden Valerius :
Role: Older Brother & Academy Honor Guard.
Age: 18 (Fourth-Year).
Mana Type: Silver-Storm / Heavy Metal. His mana is so dense it creates a physical "pressure" that can crush weaker students just by standing near them.
Appearance: A towering, muscular figure in black and silver armor. He looks like a version of Cassian that was forged in a furnace rather than left in the shade.
Personality: Brutal, uncompromising, and obsessed with "purity." He views the Valerius name as a holy vessel and sees Cassian's "Null" status as a genetic filth that must be scrubbed away.
6. Professor Hecate :
Role: High-Mage & Instructor of Combat Theory.
Age: Unknown (Mid-30s appearance).
Mana Type: Phase/Space Magic.
Appearance: Silver-haired with sharp, inquisitive eyes. She is rarely seen without her scrying scrolls and data-logs.
Personality: Analytical and objective. She is the first person to scientifically doubt Cassian's "luck," having calculated that his accidental dodges are mathematically impossible.
