Thiago ripped away the shredded velvet, exposing the blackening mark. His grip on her arm tightened, pupils shrinking as he studied the diseased tissue. "Corpse-hound venom," he stated, the words a low snarl. "It consumes from the inside, until the host is nothing but a slavering husk." He released her, stalking towards the cavern mouth. "We return to the Bastion. Now."
Inezia pushed herself upright, the cold granite a stark contrast to the fire in her veins. "Navarro fled. He is the murderer. I will pursue him to the ends of the Serrado." The venom pulsed, a faint throb, but her fury eclipsed the pain. She would not let this stop her. Not now, when she was so close to vengeance.
Thiago spun on his heel, his eyes like chipped obsidian. "And become a monster before you reach him? No. There is a cure. Deep under the fortress. His private retreat—a place forbidden to all but the Inquisitor himself." He gestured to the seeping wound. "This cannot wait. We save you first. Then we flay him." His voice was rough, edged with an urgency that brooked no argument.
Gaspar, huddled by the dying embers, his face smeared with ash and soot, whimpered. "His vault? That's… that’s where the whispers come from. Where they say Navarro does his… experiments." He shivered violently. "No one who enters leaves whole."
Thiago ignored him. "The citadel is a maze, but I know a way. An old supply tunnel, long sealed, that feeds into the lowest levels. We’ll be ghosts." He knelt, inspecting the black mark again, his hand hovering, not quite touching. "The hounds' venom is slow, but insidious. We have hours, perhaps a full night. No more."
Inezia’s gaze fell to the pulsing wound. Navarro’s hounds. Navarro’s mark. Her twin’s murder. The citadel held not just the cure, but answers. Cold resolve locked her jaw. "Then let us go." She picked up her blade, testing the hilt's balance against the prickling fire under her skin.
The journey back was a blur of shadows and hurried footfalls. Gaspar, pale as death, scurried behind them, his teeth chattering despite the exertion. They navigated the winding, moss-slicked walls of an ancient aqueduct, its abandoned channels leading them beneath the fortress itself. The air grew heavy, thick with the scent of damp earth and something else—a metallic tang that prickled her nose, like old blood and ozone.
Thiago found the concealed entrance, a heavy stone slab disguised by clinging ivy. With a grunt, he levered it open, revealing a narrow, claustrophobic shaft. "Follow close. One false step, and you’ll fall into the under-caverns." He disappeared first, his silhouette consumed by the gloom. Inezia descended next, the raw stone scraping against her knuckles, the venom-wound burning with renewed intensity. Gaspar hesitated, whimpering again, before being shooed down by a terse command from Thiago.
They emerged into a vast, echoing hall, illuminated by an eerie, cerulean glow emanating from cracks in the floor. The air was colder here, laden with the stench of volatile chemicals and something rotten, something profoundly unnatural. Towering columns of raw rock rose to a vaulted ceiling, lost in darkness. A single, heavy iron door, banded with arcane symbols, dominated one wall.
"His workshop," Thiago muttered under his breath. He pressed his palm against a symbol on the door. It glowed faintly, then pulsed with a deep crimson light. A grinding sound, like tectonic plates shifting, vibrated through the floor. The door slowly, ponderously, swung inward.
Inside lay a nightmare given form: a cavernous laboratory, shelves lined with preserved organs in cloudy jars, texts bound in cured skin, and bubbling alembics spewing noxious fumes. A complex array of brass tubing snaked across the floor, connecting various vats and humming machinery.
"Gaspar, stand guard outside," Inezia commanded, her voice low, strained. "No one enters. No one leaves." Bitter bile surged into her throat, but she swallowed it down. Her eyes scanned the grotesque tables, searching for vials or draughts.
Gaspar nodded, his face green, clutching his short sword. He positioned himself just outside the threshold, peering into the shadows of the cavernous hall.
Thiago was already moving, his gaze sharp, assessing the chaotic sprawl of Navarro’s work. "His journals. His reagents. We need to find the specific antidote for corpse-hound venom. It will be… unique."
Inezia’s eyes landed on a central dais, bathed in the same cerulean glow. There, encased in a transparent, pulsating crystalline cylinder, suspended in a viscous, golden fluid, was a human heart. It was impossibly large, and its surface was covered in faint, swirling patterns—the distinctive Vargas birthmark. Her twin’s mark. Her twin’s heart.
Her vision narrowed. Every sound in the laboratory receded, replaced by the thundering beat of her own rage. Her hands trembled, not from weakness, but from the sheer, unadulterated need to destroy. Her twin. His very essence, harvested, displayed, hooked to tubes that siphoned off its vitality into a network of alchemical vessels. She saw Navarro’s cold, calculating face in her mind, heard his condescending tones. He hadn't just murdered her twin; he was consuming him, prolonging his own wretched life with the stolen lifeblood of the Vargas line.
A faint *thump* came from outside, followed by a wet *squelch*. Then, absolute quiet. The sounds were muffled, nearly swallowed by the hum of Navarro’s machinery, but Inezia caught them. She moved, blade already in hand, rushing towards the open doorway. "Gaspar?"
Before she reached the threshold, the massive iron doors groaned, a sound of finality. With a deafening clang that rattled the very bedrock, they slammed shut, plunging the entrance to the outer chamber into total darkness. The arcane runes on the iron flared, sealing them inside the horrors of the workshop.
A voice, soft and silken, drifted from the deeper shadows of the laboratory, close by, closer than she could have imagined. "I was wondering when the stray bitch would return." Navarro stepped into the cerulean light, a poisoned blade gleaming in his hand, a cold smile gracing his lips. His eyes, devoid of warmth, fixed on Inezia’s face.
