"Stop fighting me, little surgeon. You’re only making the stitches itch."
Cassian’s voice didn’t come from the air. It echoed inside Sylvia’s skull, vibrating against her brain like a low-frequency hum. It was a dark, velvet sound, dripping with a kind of arrogance that made her want to scrub her brain with bleach.
Sylvia slammed her foot onto the brake, sending the stolen carriage skidding across the muddy road. She gasped, clutching the leather steering wheel so hard her knuckles turned white. Her heart—no, *their* heart—thundered in her chest. Two distinct beats, out of sync, fighting for the same rhythm.
"Get. Out. Of. My. Head," she hissed, her voice strained.
"I can't exactly move out when I'm sewn into your aorta, can I?" He chuckled. The sound was intimate, too close. Then, without warning, her own right hand moved.
It wasn’t her choice. Her fingers drifted upward, slow and deliberate, and brushed a stray lock of hair away from her forehead. The touch was light, almost tender, but the intent was pure mockery. He was testing the controls. He was showing her that her own body was no longer her own.
"Don't touch me," she snapped, slapping her own hand away.
"Your skin is cold, Sylvia. Are you shivering? Or is that just the fear?"
"It's disgust," she retorted, wrenching the wheel back to the right. "I’ve operated on monsters before, but I’ve never had one move in as a tenant."
"A tenant?" Cassian’s laugh was a sharp blade in her mind. "I am the King of the Abyss. You didn't just save a life; you built a bridge. Now, stop this clumsy driving before you kill us both. We’re heading east, not north."
"I’m heading where the Inquisitors aren't," she shot back, her eyes darting to the rearview mirror. The forest was thickening, the grey mist of the borderlands swallowing the road behind them. "And since I'm the one with the legs, I'm the one calling the shots."
"Legs are useless if the heart stops beating," he whispered. Suddenly, a searing heat flared in the center of her chest. It felt like a hot coal had been dropped into her sternum. Sylvia let out a choked scream and slumped against the seat, her breath coming in ragged gasps.
"What... what are you doing?"
"A reminder," Cassian said, his tone suddenly cold, devoid of the mocking playfulness. "You hold the steering wheel, but I hold the engine. If you deviate from my path, I will make every heartbeat feel like a needle through your lungs. Do we understand each other, surgeon?"
Sylvia glared at the empty passenger seat, imagining him there, leaning back with that same insufferable smirk. She hated him. She hated that she needed him to survive, and she hated that he knew exactly how to break her.
"You're a parasite," she spat, though her voice trembled.
"And you're a disgraced criminal with a banned medical license. We're a matched set."
She forced herself to sit up, fighting the lingering heat in her chest. She needed a win. She needed to prove that even if he was inside her, she was the one in control. She reached into the glove box and pulled out a heavy, iron-etched cuff—a dampening shackle she’d scavenged from the imperial lab before the escape.
"What is that?" he asked, curiosity bleeding into his voice.
"My insurance policy," Sylvia murmured. She snapped the cuff around her left wrist. It wasn't designed for Abyss Kings, but it was designed to suppress magical resonance. As the lock clicked, a sharp, electric jolt shot through her arm, and the voice in her head flickered.
Cassian let out a hiss of pain. "What... the hell... is this?"
"It's called a mute button," Sylvia said, a grim smile finally touching her lips. "You want to play the dominant Alpha? Fine. But in this body, I'm the one with the keys. Every time you try to hijack my hand or stop my heart, I'll tighten this. We'll see who's more comfortable with the pain."
There was a long, heavy silence. She could feel him reeling, the psychic pressure shifting from aggression to something more calculated. He wasn't screaming; he was observing. He was studying the walls of his new prison.
"You're bolder than you look," he finally said, his voice sounding distant, muffled by the shackle. "I almost admire the cruelty. Almost."
"Save the compliments. Just tell me where the nearest Abyss rift is. If I can get you a body—or at least a piece of one—maybe I can get you out of me."
"You think it's that simple?" He sounded amused again. "I was dismantled, Sylvia. My essence was shattered into seven pieces. You only sewed one back into your chest. Until the other six are recovered, this is our home. Your heartbeat is my only lifeline. If you die, I vanish. If I vanish, you're just a girl with a hole in her soul."
Sylvia gripped the wheel again, her mind racing. Seven pieces. A scavenger hunt through the most dangerous territories of the empire, all while sharing a nervous system with a narcissistic fallen god.
"Great," she whispered. "Just great."
"Don't be so gloomy," Cassian purred. "Think of the benefits. You'll never be lonely again. And I get to watch you fail at being a fugitive in real-time. It's practically a comedy."
"Shut up," she snapped, accelerating the carriage. "Just shut the hell up."
But as she pushed the vehicle faster, the air around them began to change. The mist didn't just thicken; it curdled. The smell of ozone and burnt sulfur filled the cabin, cutting through the scent of old leather and rain.
Sylvia slammed on the brakes again, but this time, the carriage didn't skid. It stopped dead, as if an invisible wall had materialized in the road.
"What now?" she whispered, her heart spiking.
"He's here," Cassian said, his voice suddenly sharp, devoid of any mockery. The tone was one of genuine alarm. "He found us."
Sylvia looked up. Emerging from the grey fog was a figure draped in white and gold, the stark contrast of the Imperial Inquisitor's robes looking like a bloodstain against the mist. Augustus.
He wasn't running. He wasn't shouting. He was simply walking toward them, his eyes locked on Sylvia with a terrifying, predatory hunger. He stopped ten feet from the carriage, tilting his head as if sniffing the air.
"The scent is... peculiar," Augustus said, his voice smooth and devoid of emotion. "A mix of sterile chemicals and... something ancient. Something that should have been dead."
Sylvia felt a cold sweat break across her neck. She reached for the door handle, intending to bolt into the woods, but her arm wouldn't move.
"Cassian!" she screamed internally. "Let me move!"
"I'm not the one holding you back, Sylvia," Cassian hissed. "He's suppressing the area. He's not looking for a girl. He's smelling the King."
Augustus smiled, and it was the most lifeless thing Sylvia had ever seen. He raised a hand, and the air around the carriage began to warp, the metal groaning under an invisible pressure.
"You can't hide a god in a human shell, Doctor," Augustus said, his voice growing louder, echoing through the trees. "The resonance is too loud. I can hear it. I can hear the heart that doesn't belong to you."
He took one more step forward, his eyes glowing with a pale, sickly light.
"Now," Augustus whispered, "let's see how many pieces of you I have to break to get him out."
