Chapter 4 · The Devil's Deal

"Hold still, Sylvia. I’d hate to slip and take a lung with the shard," Augustus whispered. The scalpel didn't just touch her skin; it pressed, a cold, thin line of silver biting into the soft flesh above her collarbone.

Sylvia gasped, her back slamming against the cold iron of the transport carriage. The shackles on her wrists rattled, a frantic metallic rhythm that matched her hammering heart. Augustus leaned in, his breath smelling of peppermint and old blood. He wasn't looking at her eyes—he was staring at the faint, pulsing glow beneath her skin, the place where Cassian’s fragment was anchored.

*Do it now,* Cassian’s voice snarled in her mind. It wasn't a suggestion; it was a command that vibrated in her marrow. *The moment he cuts deep, push. Give me everything you've got.*

"You're shaking," Augustus noted, his voice almost tender. "Is it fear, or is the King finally trying to talk to you? Tell me, does he sound like a god, or a dying dog?"

"He sounds like someone who's going to rip your throat out," Sylvia spat, though her voice trembled. She tried to twist away, but Augustus’s free hand clamped onto her jaw, forcing her head back. His grip was a vice, fingers digging into her cheeks.

"Bold. I like that," Augustus murmured. He shifted the blade, angling it for a precise, surgical entry. "But boldness doesn't stop a hemorrhage. Once I peel this out, you'll be a hollow shell. A memory. But the Abyss King? He'll be mine."

*Suture me,* Cassian roared, his presence suddenly expanding in her consciousness like a flood of black ink. *Not a fragment. Not a shard. Bind us. Now!*

Sylvia felt the world tilt. The physical pain of the blade was suddenly eclipsed by a mental scream. She didn't know how to do a soul-bind—not a real one, not under a scalpel—but the taboo knowledge she’d been exiled for surged forward. It wasn't about the knife; it was about the blood.

She lunged forward, not away. She slammed her chest against the blade, forcing the scalpel deeper into her own skin.

"What the hell are you—" Augustus started, his eyes widening.

Sylvia didn't answer. She reached out with her mind, grabbing the jagged, screaming energy of Cassian and pulling it. She didn't push him out; she dragged him in, stitching his essence into her own heartbeat with a mental needle and thread.

*Suture. Lock. Bind.*

White light exploded behind her eyelids. The carriage vanished. The smell of peppermint disappeared. Suddenly, she wasn't in a cage; she was standing in a void of swirling ash and obsidian glass. Across from her stood a man. He was towering, draped in shadows that looked like torn silk, his eyes two burning embers of violet hate. This wasn't a fragment. This was him.

"You're a mess," Cassian said, his voice a low rumble that shook the floor of the mind-space. He stepped closer, the air around him freezing. He didn't look at her with love—he looked at her like a tool that had finally been sharpened.

"You're the one who got dismantled," Sylvia snapped back, her breath coming in ragged gasps. "I'm the one currently bleeding out on a carriage floor. We're both messes."

Cassian reached out. His fingers didn't touch her skin, but she felt a sudden, searing heat where his hand hovered over her heart. The tension was thick, an electric current that made the fine hairs on her arms stand up. He was so close she could smell ozone and ancient rain.

"I can get us out," he whispered, his voice dropping to a dangerous, intimate level. "I can tear that man's heart from his chest. But I need a vessel. I need your body to be my anchor. Not a temporary host. A permanent bond."

"What's the catch?" Sylvia asked, her gaze locked on his. "You don't do favors."

"The catch is that you'll never be alone again," he said, his eyes narrowing. "I will feel your fear. I will taste your hunger. And you... you will feel every ounce of the rage I carry for the throne. It will burn you from the inside out. Do we have a deal, little surgeon?"

Sylvia thought of Augustus's face. She thought of the empire that had stripped her of her name and her life. She didn't want to be a victim anymore.

"Deal," she whispered.

*Slam.*

The connection snapped shut.

Sylvia's eyes flew open in the real world. A shockwave of violet energy erupted from her chest, throwing Augustus backward. The scalpel flew from his hand, clattering across the floor. He hit the wall of the carriage with a sickening thud, the wind knocked out of him.

Sylvia stood up. She didn't feel weak. She felt... heavy. Powerful. Like there was a second heart beating in her chest, one that didn't belong to her.

"What... what did you do?" Augustus gasped, scrambling to his feet, his face twisted in a mix of horror and greed.

Sylvia looked at her hands. They were steady. She stepped toward him, the shackles on her wrists snapping like dry twigs under a sudden surge of strength she couldn't explain.

"I just hired a better doctor," she said, her voice echoing with a double tone—her own, and a deep, guttural resonance that belonged to the Abyss.

She didn't wait for him to recover. She grabbed the scalpel from the floor and held it to Augustus's throat, the edge pressing into his skin. The power imbalance had flipped in a heartbeat. Now, she was the one holding the knife.

"Where is the lab?" she demanded.

"You think you've won?" Augustus sneered, though he was sweating. "Look outside, you fool."

Sylvia glanced through the small barred window of the carriage. Her blood ran cold. The carriage hadn't been moving. They were surrounded. A full battalion of the Imperial Inquisition—hundreds of soldiers in white-and-gold armor—had formed a perfect circle around them. Their spears were leveled. Their eyes were cold.

And standing at the front of the line, his cloak billowing in the wind, was the High Inquisitor.

"Sylvia Thorne," the Inquisitor's voice boomed, amplified by magic. "By decree of the Emperor, you are declared a heretic of the first order. Your life is forfeit. Your soul is to be harvested."

*Great,* Cassian’s voice drawled in her head, sounding entirely too amused. *I hope you like being a fugitive, because we just became the most wanted pair in the empire.*

Sylvia felt a sharp tug in her chest—a warning. The soldiers weren't just waiting. They were charging.

"Can you fight them?" she whispered.

*I can,* Cassian replied, his voice suddenly sharp. *But only if you let me take the wheel. Give me the body, Sylvia. Give it to me now, or we both die in this tin can.*

Sylvia looked at the closing circle of spears, then at the smug face of Augustus. She closed her eyes and let go.

"Take it," she whispered.

As the first soldier smashed through the carriage door, Sylvia felt her consciousness slide into the backseat of her own mind. Her eyes snapped open, but they weren't brown anymore. They were glowing a predatory, abyssal violet.
