The Thorncroft estate was steeped in an unnatural stillness—a silence so profound it seemed to breathe, to watch. Eleanor stood in the grand hall, her lantern casting restless shadows that danced across faded tapestries and intricately carved wood paneling. The past few days hung heavy on her, but sharper than the weight of exhaustion was the phrase etched in her mind from her mother’s journal:

"When the shadow consumes the light, the Gate shall open."

Her fingers lingered on the journal spread open on the table, its brittle pages steeped with cryptic warnings. The Codex Umbra—her mother’s obsession—offered no solace. Its puzzles deepened her resolve but felt maddeningly incomplete, like a map without its compass.

The creak of the staircase pulled her from her thoughts. Lena appeared, wrapped tightly in a blanket, her face pale and drawn. "You’re up again," she murmured, descending into the firelit gloom.

Eleanor glanced at her younger sister, weariness clouding her dark eyes. "I can’t sleep," she admitted. "The dreams... they’re relentless. And the journal—it’s like she’s trying to tell us something she didn’t have time to finish."

Lena sank into a chair near the hearth, the embers flickering faintly in her reflection. "I keep dreaming too," she said softly. "About that figure in the garden. The way it pointed at you…” Her voice trembled. “Do you think it was connected to the Obelisk?"

Eleanor nodded, her gaze falling to a sketch in the journal. The drawing—a shadowy gate etched with arcane symbols—was haunting in its detail. Beneath it, a chilling inscription read:

"To walk the path, one must first become the shadow."

The morning sun struggled to pierce the fog as the sisters entered Blackthorn. The town square was desolate, its stillness broken only by the looming presence of the Obelisk. The monolith stood silent and inscrutable, its carved surface seeming to ripple faintly as Eleanor approached.

She hesitated, then pressed her gloved hand against the stone. A faint warmth pulsed beneath her touch, as though the Obelisk itself had a heartbeat.

“Eleanor, don’t,” Lena hissed, casting nervous glances at the darkened windows around them. “What if someone sees?”

“Let them,” Eleanor said firmly, stepping back to study the towering structure. “This thing is tied to us, Lena. To Mother. I can feel it. And I won’t let fear stop me from understanding why.”

Before Lena could respond, a guttural cry broke the silence. They turned to see a man stumbling out of an alley, clutching his chest, his face twisted in terror.

“Help me!” he rasped, his voice dropping into a guttural chant. Eleanor’s blood chilled as fragments of the ancient script from the Codex spilled from his lips.

Lena started forward, but Eleanor caught her arm. “Wait,” she whispered, her voice tense.

The man’s head snapped up, his eyes black as pitch. With an inhuman speed, he lunged at Eleanor. She sidestepped, narrowly avoiding his grasp. He hit the ground hard, convulsing violently before falling still.

Lena knelt beside him, trembling. "Eleanor, what just happened?”

Eleanor crouched, her gaze fixed on the faintly glowing symbols that had appeared on the man’s skin before fading to nothing. “He’s dead,” she said quietly. “But he was marked.”

That evening, the Thorncroft library became their refuge. Eleanor worked feverishly, surrounding herself with scattered notes, ancient texts, and her mother’s journals. Lena lingered near the doorway, her worry etched plainly across her face.

“You can’t keep doing this alone,” she said finally. “What if something happens to you?”

Eleanor looked up, her expression softening. “I’m not alone. I have you.” She gestured to a stack of notes. “If you mean it, start here. They reference artifacts connected to the Obelisk.”

After a moment of hesitation, Lena stepped forward and took the papers. “Fine. But if we’re doing this, we’re doing it together.”

Hours passed in near silence, broken only by the crackle of the fire and the rustling of pages. Then Eleanor froze, her breath catching. She pointed to a passage in the Codex, her voice trembling as she read aloud:

“The Hollow One shall rise when the veil between realms is thinnest. Shadows will consume the light, and the Gate shall open, unleashing that which lies beyond.”

Lena paled. “What does it mean? Shadows consuming light? The Gate?”

Eleanor shook her head. “I don’t know. But the Obelisk is the key. If we can understand it, we might have a chance to stop this.”

The sisters ventured to the outskirts of Blackthorn the next day, following a lead to an ancient, crumbling church. According to the Codex, its catacombs held a relic known as the Mirror of Ashes, said to reveal truths hidden in shadow.

The air inside was damp and heavy, thick with the scent of decay. Beneath the shattered altar, they uncovered a hidden staircase spiraling into darkness.

“Do you think Mother ever came here?” Lena whispered as they descended.

“She must have,” Eleanor replied, running her fingers over the symbols carved into the stone. “These match her sketches.”

The catacombs were a maze of cold stone and silence, but at the heart of the labyrinth, they found the Mirror of Ashes. It sat on a pedestal, its surface cracked and tarnished.

“This is it,” Eleanor murmured, stepping forward.

As her fingers touched the mirror, light exploded outward, bathing the chamber in an ethereal glow. Shadows danced along the walls, forming shifting, watchful shapes.

In the mirror, Eleanor saw herself standing before the Obelisk. Behind her loomed a massive gate, its surface writhing with tendrils of shadow. A voice, deep and resonant, echoed in her mind:

“The path is set. The Hollow One calls. Will you answer?”

She stumbled back, breaking the connection. The light vanished, leaving them in suffocating darkness.

“We need to leave,” Eleanor said, her voice barely above a whisper.

When they emerged from the catacombs, the sky above Blackthorn churned with dark clouds. The sun was obscured, and the town felt as though it had slipped into the shadow of another world.

Eleanor gripped Lena’s hand. “Whatever’s coming, it’s already begun.”

Lena’s voice trembled. “What do we do now?”

Eleanor glanced toward the Obelisk, its dark form barely visible through the mist. “We find the Gate. And we stop it.”
