You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

The underground station yawned wide and dark, its abandoned platform flickering faintly beneath the yellow glow of a battered flashlight. Detective Harlow Quinn adjusted her leather
watch
, glancing at the time. Nearly midnight.
The air was thick with
the scent of damp concrete, broken metal, and something else—something darker, underlying. She stepped
carefully
over a tangle of shattered glass and scattered debris, her eyes sharp despite the gloom. The station had
been closed
for years, but tonight, there was an odd sense of activity—noises muffled and muffling, almost as if the darkness itself
was listening
. Standing a few steps from the center of the platform was her colleague, Detective
Evans
, shivering
slightly
beneath an overcoat that looked too thin for the cold underground air. He pointed toward a set of footprints leading toward a tunnel entrance obscured by shadows. "It's fresh,"
Evans
muttered, voice hushed. "Likewise, no signs of forced entry. No blood—nothing that screams violent struggle." Quinn knelt, running gloved fingers
cautiously
along the cracked edge of a jagged metal shard. The evidence didn't make sense. No blood spatter, no signs of a fight—just a faint trail of footprints rising and falling, as if someone had walked
carefully
, almost
deliberately
. She examined the ground, noticing a faint shimmer along the edge of one footprint. She crouched closer, eye narrowing. The surface beneath was uneven, but what caught her attention was the faint glow of something almost imperceptible near the prints. She reached into her pocket, fingers closing around her Veil Compass, the small brass thing
etched
with protective sigils, a gift from the market. She tapped the needle,
watch
ing it sway
slightly
toward the tunnel. "
Evans
," she said quietly, voice carrying a
weight
of certainty even as she sounded cautious. "Take a look at this." He followed her gaze, stepping closer. She pointed to the shimmering trail. "This isn't just dirt or moisture. Something's been here—something supernatural." She hesitated, then pulled out her phone, flipping through her notes, but the compass was already pointing—a little needle twitching faintly, lips of verdigris catching the sparse light.
Evans
looked skeptical. "Supernatural? Quinn, you’re past that phase." She gave him a steady look. "If this is what I think it is, you’ll want to see for yourself." She reached into her satchel, pulling out a folded piece of cloth soaked with a
carefully
prepared substance—part salt, part ash, an old trick to reveal magic lingering in the environment. She sprinkled it along the trail,
watch
ing as the faint shimmer intensified, the dust flickering like fleeting sparks caught in a draft. The tunnel beckoned, cold and yawning, a maw that
seemed to
swallow all sound. Quinn hesitated only for a second, then stepped inside, bathed in shadows. The air grew cooler, sharper, like crossing a threshold into another world. Her eyes darted, noting the contours of the tunnel walls, unmarked except for the faintest runic etchings that
seemed to
ripple and shift when she looked directly at them. She felt a prickle at the back of her neck, a whisper of something unseen. "Keep your wits about you," she murmured, clutching her companion's arm briefly before moving forward. The glow of her flashlight illuminated a series of glyphs carved into the tunnel walls—arcane symbols, familiar but faintly distorted, as if painted in haste or under duress. Quinn kept her gaze steady, noting how the symbols
seemed to
pulse faintly with a life of their own. It reminded her of the veiled energies she’d studied long ago—powers that thrived beneath the glare of ordinary sight. Then something caught her eye. Near the ground, where the footprints led, a faint ripple of blackish residue, like spilled ink, spread outward, pulsating
gently
. She knelt again, scraping at the surface with her fingernail. It didn’t wipe away. Instead, it
shimmered
, reminiscent of a protective spell—trapped, perhaps, or broken. "See this?" she said
softly
. "This isn’t just dirt or mud. Someone invoked something here."
Evans
scoffed, stepping back into the faint light. "You’re telling me a ghost — or whatever’s lurking — left that behind?" "I’m telling you," Quinn said, voice low, "that someone or something doesn’t want us here. And I want to know why." Suddenly, the needle of her Veil Compass jerked
sharply
, toward a small alcove to their left. Quinn’s heart quickened. She had learned long ago to trust her instincts—and her tools. "Stop," she ordered quietly, raising a hand. “If there's a rift or portal nearby, it’ll be sensitive.” They advanced toward the alcove, where a faint, unnatural shimmer hung like a curtain of smoke. She gestured for
Evans
to stay back, then reached out
cautiously
. As her hand swept through the mist, it rippled violently, then dispersed like a crack in a thin sheet of glass. A faint whisper of voices
echoed
. Not voices—more like
echoes
of thought, unseen currents stirring the air. Quinn felt her skin prick with
anticipation
, her mind tuning into the whisperings that danced behind her eyes. “Hold up,” she whispered, voice tight with focus. “This is definitely a nexus point. Someone is messing with the veils out here.”
Evans
looked wary. "Are you saying—" "Someone’s trying to open—or close—a portal." The compass finally steadied, the needle pointing unwaveringly toward a deeper, darker part of the tunnel. And she knew, right then, that what lay beyond was no ordinary disturbance. Something
was waking
, or breaking free. It explained the strange residue, the glyphs, and the shimmer—what others had missed in their hurried scans. Quinn stepped back, eyeing the tunnel with a mixture of caution and resolve. “
Evans
, we need backup. Without it, this gets even worse. And I suspect we’re not just dealing with some petty supernatural prank. This—” she gestured at the residue, the glyphs, the shimmering light—“this is something ancient. Something dangerous.” He looked uncertain but nodded. Together, they prepared to move further into the darkness, senses on high alert. The veil was thin here, and whatever lurked beyond was stirring. Quinn’s fingers tightened around her satchel, feeling the
weight
of her knowledge and her duty. The shadows whispered again, and she was already
calculating
her next move—to close the rift, or to understand what it
was trying
to tell her. Because something hidden deep beneath this abandoned station had been waiting. And now, it was awake.
