To defeat a monster, one must understand its lifespan.
In her previous existence, her tormentors had been ordinary men. They possessed the standard human expiration date. Her husband had eventually grown slow, his joints aching, his physical strength waning as his liver hardened from decades of cheap scotch. Time had been her only ally, the slow, inevitable decay of the mortal body doing what the legal system had refused to do.
But magical beings, particularly those possessing immense power, did not decay on a standard timeline.
Sunshine sat on the floor of her bright, yellow-wallpapered nursery, a slate chalkboard resting against her knees. She was holding a piece of white chalk, the scratching sound rhythmic and steady.
She was calculating the exact age of Albus Dumbledore.
If she was going to hide from the Book of Admittance, she needed to understand the psychology of the man who oversaw the institution. The Headmaster of Hogwarts was not just a bureaucrat; he was the Chief Warlock of the Wizengamot, the Supreme Mugwump of the International Confederation of Wizards, and the only man Voldemort ever feared. He was the absolute, uncontested apex of the Light's power structure.
Born: August 1881. Sunshine wrote the date in sharp, jagged numbers.
Current Year: 1986.
She did the subtraction. 105years old.
Sunshine stared at the number, a cold, heavy knot forming in her stomach. One hundred and five years.
To a six-year-old child, a century is a myth. But to the sixty-year-old soul inside her, it was a terrifying metric of accumulated experience. Dumbledore had lived through the dawn of the 20th century. He had witnessed the rise and fall of Grindelwald—a global, devastating magical war that mirrored the atrocities of the mundane world's World War II. He had navigated the political minefields of the Ministry for decades before Voldemort ever rose to power.
He was not a reactive man. A man who lives for a century does not make impulsive decisions. He plays the long game. He plans in decades, not days. He was a spider sitting in the center of a web that spanned the entire continent, feeling the vibrations of every single magical core that sparked to life within his jurisdiction.
If Dumbledore felt the uniquely dark, incredibly potent magical signature of a firstborn Addams child flaring across the ocean—a signature attached to a family the British Ministry had exiled centuries ago for being uncontrollable—he would not ignore it. He would see it as a variable that needed to be managed, controlled, or neutralized.
"I cannot simply be quiet," Sunshine whispered to the empty room. "Quiet is suspicious. A quiet Addams is a plotting Addams."
She wiped the slate clean with the sleeve of her pinafore.
To fool a 105-year-old chess master, she couldn't just hide her pieces off the board. She had to convince him she didn't know how to play the game at all. The Quill of Acceptance, locked away in its tower in Hogwarts, detected the spark of magic in a child. It didn't just sense heritage; it sensed active, potent magical capability.
If she was going to dodge the Hogwarts letter, she had to become a Squib. Or, at the very least, she had to bind her core so tightly that her magic registered as nothing more than the faint, useless background radiation of her bloodline.
It was a horrifying prospect.
For the past two years, under Morticia and Grandmama's tutelage, Sunshine had learned to embrace her dark affinity. She had learned the intoxicating thrill of channeling her trauma into power. The magic was the first thing in two lifetimes that had ever made her feel truly safe. To lock it away, to deliberately cripple herself, felt like cutting off her own hands.
But survival required sacrifice.
The practical application of her plan began that very afternoon in the grand conservatory.
Morticia was conducting a lesson on coercive botany. The objective was simple: use wandless magical intent to force a highly stubborn, magical Night-Blooming Cereus to open its petals in the middle of the day.
Wednesday, standing a few feet away in a stark black dress, had accomplished the task in under thirty seconds. She had simply stared at her assigned flower, her dark eyes projecting such a concentrated, freezing aura of absolute menace that the plant had popped open entirely out of self-preservation, its white petals trembling.
"Flawless execution, my little storm cloud," Morticia praised, stroking Wednesday's raven hair. "Fear is a highly effective nutrient."
Morticia turned her attention to Sunshine, who was standing before her own tightly closed Cereus bud.
"Now you, my golden deception," Morticia murmured softly, her dark eyes expectant. "Show me the beautiful rot beneath your sunny exterior. Command the bloom."
Sunshine placed her hands on the edge of the stone planter. She looked at the flower.
In her mind, the heavy, dark well of her Addams magic was pulsing, ready to be unleashed. It wanted to reach out, to warp the plant, to force it open with the same icy, suffocating pressure she had used on the Nundu in the swamp.
Instead, Sunshine took a slow, deep breath, and visualized a massive, heavy iron vault door slamming shut over her core.
The physical sensation of suppressing her magic was agonizing. It was like trying to hold your breath while running a marathon. Her chest tightened, a dull, throbbing ache radiating from her sternum down to her fingertips. The magical energy, denied its release, pushed back against her internal barriers, creating a sickening pressure behind her eyes.
She stared at the flower. She poured all her mundane, non-magical concentration into it, deliberately starving the intent of any magical frequency.
Nothing happened.
The Cereus bud remained tightly closed, its green sepals stubbornly locked.
Morticia frowned slightly, a delicate, elegant crease appearing on her pale forehead. "Focus, Sunshine. Do not merely look at it. Pierce it with your malice. Let the shadows in your blood dictate its growth."
Sunshine maintained the iron grip on her core, ignoring the throbbing pain in her head. She let a perfectly constructed look of childish frustration cross her rosy face. She squeezed her eyes shut, furrowing her brow, acting out the physical exertion of trying and failing.
"I... I can't, Mother," Sunshine said, her high voice trembling just enough to sound authentic. "It won't listen to me."
Morticia's frown deepened. She glided forward, placing a hand over Sunshine's small hands on the planter. The gothic matriarch closed her eyes, extending her own vast, dark magical awareness, attempting to feel the pulse of her daughter's core.
Sunshine braced herself. Morticia was powerful. If she sensed the iron vault, she would know Sunshine was lying. Sunshine pushed the suppression deeper, wrapping the vault in layers of static, making her magical signature feel thin, weak, and fractured.
Morticia opened her eyes. The look of expectation was gone, replaced by a sudden, profound, and deeply tragic sorrow.
"Oh, my poor, beautiful anomaly," Morticia whispered, dropping to her knees so she was at eye level with her six-year-old daughter.
"What is it, Tish?" Gomez asked, dropping from the iron rafters of the conservatory where he had been hanging upside down to observe the lesson. He landed silently beside them, his manic energy instantly subdued by the tone of his wife's voice.
Morticia reached out, gently cradling Sunshine's face in her cold hands. Her thumbs brushed over the golden curls she despised so much.
"Her core," Morticia said softly, her voice thick with genuine, gothic grief. "It is... fading, Gomez. The golden curse is not merely aesthetic. It is structural. The sickening radiance of her exterior is actively consuming the darkness within her. Her magic is drying up like a slug in the summer sun."
Gomez gasped, clutching his heart as if he had been physically shot. He stared at Sunshine, his eyes wide with horror and overwhelming pity.
"A Squib?" Gomez whispered, the word sounding like a terminal diagnosis. "Our firstborn? Doomed to wander the earth without the glorious ability to curse her enemies? Trapped in a mundane existence?"
In the wizarding world, a Squib was a source of profound shame, often hidden away or disowned.
But this was the Addams family.
Gomez didn't turn away in disgust. He threw himself forward, wrapping his arms around Morticia and Sunshine in a crushing, desperately loving embrace.
"Oh, my tragic, doomed little Sunbeam!" Gomez wept loudly, tears streaming down his cheeks. "What a magnificent, agonizing burden you must bear! To be born into the royalty of the macabre, only to be stripped of your fangs! We shall love you twice as fiercely! We shall buy you the finest mundane weaponry money can buy! You won't need magic to cause suffering; we will teach you accounting!"
Morticia held her tightly, her icy cheek pressed against Sunshine's golden curls. "Do not despair, my darling. You may lack the spark, but you still possess the intellect of an executioner. We will protect you from a world that will never understand your magnificent tragedy."
Sunshine buried her face in her father's velvet vest. The pain in her chest from suppressing her core was intense, but it was eclipsed by a sudden, sharp pang of profound guilt.
She was lying to them. She was breaking their hearts, playing upon their deepest fears and aesthetics to secure her own camouflage. The sixty-year-old woman inside knew it was a necessary cruelty, a tactical sacrifice required to keep them all off Dumbledore's radar. If they believed she was a Squib, they would not push her to perform magic that the Ministry could trace.
She looked past her father's shoulder. Wednesday was standing by her successfully bloomed, terrifying flower. The three-year-old's dark, bottomless eyes were locked onto Sunshine.
Wednesday didn't buy the act for a single, solitary second. She remembered the Nundu. She remembered the crushed Gorgon-Spider. She knew her sister possessed a suffocating, lethal power.
But Wednesday also possessed the tactical genius of the Addams line. She gave Sunshine a single, microscopic nod of understanding, silently agreeing to uphold the lie.
Sunshine closed her eyes, maintaining the agonizing pressure on her magical core. She was no longer a sleeper agent. She was a ghost. Let the wizarding world search the globe for threats. They would look at the Addams estate and see a manic father, a gothic mother, a chaotic boy, a terrifying girl, and a pathetic, golden-haired, non-magical tragedy.
The British wizard's age had been calculated, and his trap had been entirely circumvented. The vow of avoidance was now in full, painful effect.
