Lyla's Secret Illness
Only Lyla, Dominic, and Cor know the truth.
To outsiders — even Sirius — her frailty appears as a simple, long-term illness.
The Crown is never informed; King Regis and the royal family remain unaware.

Symptoms
White hair since childhood.
Night fevers and weakness after exposure to strong magic or Astrals.
Periodic "aether seizures," during which her veins glow faintly violet.
Standard healing magic or restorative techniques do nothing — some even worsen her pain.

Classification
⚜️ Dormant Evolutionary Mutation
Originating from Lyla Leonis' incurable disease, Nyxshade Syndrome, this rare variant exists only within Sirius Blake — the sole carrier of its dormant, adaptive form.
---
Overview
While Lyla's body rejected Astral aether, Sirius' body integrated it.
The corrupted magic that destroyed her instead reshaped in him, becoming the foundation of his Adaptive Resonance — the instinct to evolve through pain, failure, and conflict.
The disease remains inside him, but never awakens — contained by his immense willpower and the balanced duality of his soul.
---
Dormant Properties
The syndrome is completely non-lethal in Sirius.
It lies asleep within his genetic and aetheric signature.
When his body suffers trauma or magical strain, the dormant curse reacts by enhancing regeneration, reflexes, and adaptability.
Overuse (continuous resonance bursts or prolonged Astral exposure) causes brief echoes of the original curse — pain near the heart, violet flickers in veins, or silver flashes in his eyes — before stabilizing.

Inherited Connection
Lyla Leonis: Original bearer of Nyxshade Syndrome — body rejects Astral energy.
Sirius Blake: Dormant variant — body harmonizes Astral energy under duress.
Her suffering became his strength.
The disease mutated during conception, transforming a terminal curse into the seed of survival.

In-World Knowledge
Completely unknown to the world.
Only Cor and Dominic ever suspected Sirius might have inherited anything — neither confirmed nor told him.
Even advanced magical scanners and Lucian medical systems detect nothing abnormal; the mutation hides within normal aether flow.
