The air in the museum lab was thick with the scent of ozone. Sera reached for the glowing relic—a golden compass she had spent weeks cleaning—but as her fingers brushed the cold metal, the world tilted. A roar like a jet engine filled her ears, and the floor beneath her sneakers simply vanished. She fell through a kaleidoscope of blue light, the wind whipping her lab coat around her like broken wings.

In the Kingdom of Oakhaven, five hundred years in the past, King Alaric sat alone in his darkened bedchamber. To his subjects, he was the "Iron King," a man of stone. But in the privacy of the night, he was a man crumbling. He leaned over a golden basin, a violent cough racking his frame. When he pulled his silk handkerchief away, it was stained crimson.

"Not tonight," he hissed, his voice a ragged shadow of its usual authority. "I have not cleared the court of snakes yet. I cannot die."

Suddenly, the vaulted stone ceiling above him erupted in a flash of blinding light. CRASH! The heavy canopy of his bed shattered. Dust, splinters, and silk feathers exploded into the air. Alaric threw himself backward, reaching for the dagger beneath his pillow. As the dust settled, he didn't see an assassin. He saw a girl.

She was dressed in strange, translucent white robes and blue trousers. She lay sprawled across his furs, gasping for breath.

"Who sent you?" Alaric lunged, pinning her down. The cold steel of his dagger pressed against the soft skin of her throat. "Speak! Are you a witch from the North?"

Sera’s head spun. She looked up into the most terrifyingly beautiful face she had ever seen—golden eyes burning with a mix of fury and exhaustion. But as a medical student, she noticed the tremble in his hand and the fresh blood on his lip.

"I'm... I'm an intern," she managed to choke out. "And you... you're in respiratory failure. If you don't put that knife down and let me check your airway, you won't live to see the sunrise."

Alaric froze. How could this girl, fallen from the sky, know the secret he had hidden from everyone?

Thud. Thud. Thud. Heavy boots echoed in the hallway.

"Your Majesty!" the Captain of the Guard shouted through the doors. "We heard a collapse! Open the doors at once!"

Alaric looked at the girl. If the guards saw her, she would be burned for sorcery. If she told them he was dying, his enemies would strike before dawn.

"One sound," he whispered, his face inches from hers, "and I will ensure you never speak again." He motioned toward the deep shadows of the stone alcove. "Hide."

Sera scrambled into the darkness just as the doors groaned open. Alaric stood in the center of the wreckage, his posture rigid. "A structural failure," Alaric replied coldly to the guards. "The wood gave way. Leave me."

The guards retreated, and the heavy doors thudded shut. Alaric turned slowly toward the alcove, leaning heavily on the bedpost.

"You," he said, looking toward Sera’s hiding place. "You spoke of my condition. If you are not a witch, then prove your worth. If I do not see the sunrise, neither shall you."

Sera stepped out of the shadows, her eyes falling on her medical bag. "Then we have work to do," she said. "Move toward the light. I need to see how much time we actually have."

The silence in the bedchamber was heavy, broken only by the King’s ragged, wet gasps. Alaric leaned against the carved bedpost, his knuckles white.

"You have one chance, girl from nowhere," he rasped, the dagger still clutched in his hand. "Heal me, or the guards will return for your head."

Sera didn't hesitate. She knelt and unzipped her black medical bag. The sound of the zipper—a sharp zip!—made the King flinch. He had never heard such a sound. She pulled out a small, battery-powered pulse oximeter and a stethoscope.

"Give me your hand," she commanded.

Alaric stared at her like she was speaking a foreign tongue. "You dare command a King?"

"I'm a doctor—well, almost one," Sera snapped, her modern-day bossiness slipping out. "And right now, you're just a patient who’s about to faint. Hand. Now."

Bewildered by her lack of fear, Alaric extended his hand. Sera clipped the plastic device onto his finger. It beeped, and a tiny red light flickered on the screen. Alaric recoiled, his eyes wide.

"What sorcery is this? It glows with the red of a demon’s eye!"

"It’s a tool, not a demon," Sera muttered, reading the numbers. Oxygen 88%. Heart rate 110. "Your lungs are filling with fluid. I need to listen."

She pressed the cold metal of the stethoscope to his bare chest. Alaric froze as she leaned in close. He could smell the strange, clean scent of her world—like citrus and soap—so different from the heavy incense and musk of his palace.

"I need to give you an injection," Sera said, reaching for a pre-filled syringe of diuretic from her emergency kit.

Alaric saw the gleaming needle and his eyes turned cold. He grabbed her wrist, his grip like iron. "A silver needle? You intend to poison me while I am weak."

"If I wanted you dead, I would have let you choke five minutes ago," Sera stared him down. "This is the 'Little Secret' we're keeping, right? Your life depends on me. And my life depends on you. That’s our deal."

Alaric looked into her stubborn, bright eyes. For the first time in his life, he saw someone who wasn't looking at his crown, but at him. He slowly let go of her wrist.

Sera administered the shot. Minutes later, the King’s breathing slowed. The frantic pounding in his chest eased. He slumped back against the pillows, the color returning to his face.

"You have... strange magic," he whispered, looking at the empty plastic syringe.

"In my world, we call it medicine," she replied, packing her bag. "But here, I guess it’s a secret."

Alaric stood up, his tall frame towering over her. He reached out, his thumb brushing a smudge of dust on her cheek.

"From this moment, you do not exist," he said, his voice deep and possessive. "You are the shadow in my room. The ghost in my halls. If anyone sees you, I will say you are my personal physician—and anyone who speaks of you will lose their tongue."

He leaned down, his lips close to her ear. "But if you betray me, or if my 'illness' reaches the ears of the council... I will personally ensure you are the first to fall."

Sera felt a shiver—half fear, half something else. "Deal, Your Majesty."

[Cliffhanger]

A loud knock sounded at the door. "Your Majesty! The Prime Minister demands an audience. He says he smelled smoke from your chambers!"

Alaric looked at Sera. There was no time to hide her in the alcove. He grabbed her waist and shoved her under the massive, fur-covered bed.

"Don't. Move."

As the door opened, Sera saw the polished boots of the Prime Minister enter the room—and then she saw him stop right in front of the bed, his eyes landing on her modern sneaker peeking out from under the silk hem.

The heavy oak doors groaned open. Sera lay flat on the cold stone floor, her heart hammering against her ribs so loudly she was sure the Prime Minister could hear it. Through the narrow gap under the bed’s silk fringe, she saw a pair of black, pointed leather boots—the kind worn by someone who enjoyed stepping on others.

"Your Majesty," a voice like dry parchment scraped the air. This was Prime Minister Malphas, a man whose smile never reached his cold, calculating eyes. "You seem... agitated. And the room... it smells of burnt lightning."

Alaric stood tall, his shadow stretching across the floor and partially covering Sera’s hiding spot. He adjusted his robe, pointedly stepping on the tip of Sera’s modern sneaker to shove it further under the shadows.

"I was testing an old alchemical scroll, Malphas," Alaric said, his voice as cold as ice. "I didn't realize I needed your permission to read in my own chambers."

"Of course not, Sire," Malphas said, but he didn't leave. He began to pace. Step. Click. Step. Click.

Under the bed, Sera squeezed her eyes shut. She was inches away from the Prime Minister’s boots. She could see the dust on his heels. Then, he stopped.

"And this?" Malphas leaned down. His hand reached toward the floor.

Sera stopped breathing. He had spotted something. Just as his fingers touched a stray glint of metal—a bobby pin that had fallen from Sera's hair—Alaric let out a violent, hacking cough.

He didn't just cough; he collapsed onto the edge of the bed, the weight of his body making the wooden frame groan above Sera.

"Your Majesty!" Malphas pulled back, his eyes narrowing. He wasn't worried; he was observing. Like a vulture waiting for a lion to die.

"Out," Alaric gasped, clutching his chest. "Call the Royal Physician if you must... but get out of my sight."

Malphas bowed low, but his eyes lingered on the bed one last time. "As you wish. But remember, Sire... a King who cannot breathe cannot speak. And a King who cannot speak cannot rule."

The doors finally slammed shut.

Sera scrambled out from under the bed, gasping for air. She found Alaric slumped on the floor, his face ghostly pale. She reached for her medical bag, but he grabbed her arm, his grip weak but desperate.

"He knows," Alaric whispered. "He doesn't know about you... but he knows I am failing."

Sera looked at the King. In the modern world, she was just an intern getting coffee for senior doctors. Here, she was the only thing standing between a King and a coup.

"He doesn't know about me yet," Sera said, her voice firm. "But he’s going to be very confused when his 'dying' King suddenly starts looking a lot healthier."

Alaric looked up at her, a faint, dark smirk touching his lips. "You are a strange creature, Ghost Girl. Tell me... how do we begin this 'magic'?"

Sera pulled out a bottle of high-strength vitamins and an inhaler. "First, we fix your breathing. Then, we find you a place to hide me where vultures don't pace."

Alaric’s eyes darkened with a new kind of intensity. "There is a wing of this palace that has been sealed for a hundred years. They say it is haunted by the 'White Lady.' Starting tonight, you shall be the ghost that keeps it that way."

[Cliffhanger]

As Alaric leads her through a secret passage behind a tapestry, Sera looks back and sees Malphas’s spy—a small, black raven—perched on the window sill, watching her every move.
