The beep of Eren’s computer broke the silence of the early morning, an email alert that seemed ordinary yet carried an air of mystery.

“Guys, look at this,” he called out, squinting at the sender's name, a security firm none of them had heard of before.

As Mia’s name flashed on the screen, a collective breath was held.

The message was brief, claiming to have information about Mia’s demise, but it lacked any real details. “It’s got to be a scam,” Leo grumbled, his voice heavy with skepticism.

But Tara, ever the voice of intuition, paused. “What if it’s a message from Mia herself?” she suggested, tapping her chin thoughtfully.

The idea seemed far-fetched, yet Mia was known for her knack for embedding clues in the digital world like breadcrumbs leading to the truth.

Driven by a mix of hope and urgency, they dove into the depths of the email, decoding its hidden message bit by bit, with the help of Cipher.

"This does look like Mia's work to me," Cipher exclaimed.

Leo began to demonstrate increasing curiosity as Cipher gradually unravelled the hidden message.

“Hmm, I believe these are coordinates. It’s leading us somewhere in the city.”

A surge of adrenaline coursed through them. Could this be a trap? Or was it truly a message from Mia, a final act of defiance against the forces that had taken her?

They couldn’t ignore it. Geared up and with their senses heightened, they ventured into the bustling city, following the digital trail Mia had left behind.

---

The coordinates led them to an abandoned warehouse, its dilapidated exterior masking the secrets it held within.

“This place feels…off,” Tara whispered, her foresight tinkled.

Eren, his ability to sense deception tingling, nodded in agreement. “There’s something here, something hidden beneath the surface.”

With Leo taking the lead, they cautiously entered the warehouse.

---

The warehouse was a labyrinth of shadows and dust, the air thick with anticipation.

Leo led the way, his eyes scanning every corner for potential threats. Tara followed closely, her brow furrowed in concentration as she tried to pierce the veil of uncertainty with her foresight. Eren brought up the rear, his senses tingling with a mixture of apprehension and excitement.

"This place really does feel off, and not very good for my allergy," Tara whispered, her voice barely audible above the rhythmic thudding of their hearts.

They navigated through the maze of abandoned crates and broken machinery, the silence broken only by the occasional creak of rusted metal.

Suddenly, Leo froze, his hand raised in a gesture of caution.

"Do you hear that?" he whispered, his voice strained.

A faint hum filled the air, growing louder with each passing second. It was a digital melody, discordant and unsettling, as if the very fabric of the warehouse was singing a song of warning.

"It's coming from behind that stack of crates," Tara whispered, pointing towards a towering wall of dusty containers.

Leo, with his characteristic stoicism, took the lead, his steps measured and silent. He slowly moved the crates aside, revealing a hidden alcove bathed in an eerie blue glow.

"What is that?" Tara gasped, her eyes widening in surprise.

In the center of the alcove, resting on a makeshift pedestal, was a device unlike anything they had ever seen.

It was a sphere of swirling light, pulsating with a rhythm that seemed to echo the discordant hum they had heard earlier.

Eren stepped forward, drawn by an invisible force.

He reached out a hand, his fingers brushing against the sphere's surface. A jolt of energy coursed through him, sending a wave of dizziness washing over him.

"Eren!" Tara exclaimed, rushing to his side. "Are you alright?"

He blinked, shaking his head to clear the fog. "I...I saw something," he stammered, his voice filled with awe. "Visions, of the past, of the future...of Mia."

A collective gasp filled the air. Could this sphere be the key to understanding Mia's disappearance? Was it a message, a trap, or something else entirely?

Love this novel? Read it on Royal Road to ensure the author gets credit.

Before they could ponder further, the warehouse shuddered violently.

The digital hum intensified, morphing into a deafening siren. Red lights began to flash, bathing the room in an ominous glow.

"What's happening?" Leo demanded, his voice tight with urgency.

"It's a trap!" Tara exclaimed, her foresight kicking in. "We need to get out of here!"

As if on cue, the walls of the warehouse began to close in, the metal groaning and twisting as the space constricted.

"Well, this is just fantastic," Leo grumbled, his voice dripping with sarcasm. "Just another Tuesday for the Guardians of Truth, trapped in a collapsing warehouse with a mysterious glowing orb."

Tara, ever the pragmatist, rolled her eyes. "You know, complaining won't stop the walls from closing in, Leo."

"Just making an observation, Sherlock," Leo retorted, his tone playful despite the situation.

Eren, still reeling from the visions he'd received from the sphere, shook his head to clear his thoughts. "Guys, we need to focus. This sphere, it's Mia's message. I know it."

"And how exactly do you propose we decipher it while being squished like grapes?" Leo asked, gesturing to the rapidly shrinking space.

"Maybe we can use it to fight back?" Tara suggested, her eyes gleaming with a spark of hope. "If it's connected to Mia, it might hold some kind of power."

Eren nodded, his determination solidifying. "Let's do it. Leo, see if you can buy us some time. Tara, focus your foresight on the sphere. Cipher, see if you can remotely access its data. We need to work together on this."

Leo cracked his knuckles, a mischievous grin spreading across his face. "Alright, showtime!" he declared, before charging towards the closing wall with a mighty roar.

Tara closed her eyes, her brow furrowed in concentration as she reached out to the sphere with her mind.

Cipher, on the side, initiated a digital assault on the sphere's defenses.

As the walls drew closer, Leo braced himself, his muscles taut. With a mighty heave, he managed to slow the wall's progress, buying precious seconds for his team.

"Hurry!" he grunted, his face reddening with exertion.

Tara gasped, her eyes snapping open. "I see it! A sequence, a code...it's unlocking something within the sphere!"

Cipher's fingers danced across the keyboard, his eyes glued to the screen. "I'm in! Downloading data now!"

Suddenly, the sphere pulsed with a blinding light, throwing them backwards. The warehouse shook violently, and then, just as abruptly as it began, everything stopped.

The walls froze in place, the red lights flickered and died, and the deafening siren faded into silence.

Eren blinked, his vision slowly returning. He looked around, his heart still pounding in his chest.

The warehouse was still, the air thick with dust and anticipation.

"What...what happened?" Tara asked, her voice shaky.

Eren stared at the sphere, which now glowed with a soft, white light. He took a tentative step forward, drawn by its gentle hum.

As he reached out to touch it, a voice echoed in his mind, a voice he knew all too well.

"Eren," Mia's voice whispered, warm and familiar. "It's time."

He gasped, his eyes widening in surprise. "Mia? Is that really you?"

"There's no time to explain," Mia's voice continued, urgent and clipped. "The artifact...it holds the key. You must find it."

Before Eren could ask what she meant, the sphere pulsed once more, and the world around them dissolved into pixels and digits.

---

When Eren opened his eyes again, he found himself standing in a vast, digital landscape. The air shimmered with code, and the ground beneath his feet felt like walking on a cloud of data.

"Whoa," Leo exclaimed, his eyes wide with wonder. "Where are we?"

"This is...a digital realm," Tara said, her voice filled with awe. "Mia must have transported us here."

Eren looked around, his gaze drawn to a towering structure in the distance. It was a colossal archway, pulsing with energy and adorned with intricate symbols that seemed to shift and change before his eyes.

"The artifact," Mia's voice echoed in his mind. "It's within the archway."

"But how do we get there?" Leo asked, scratching his head. "It looks miles away."

"We walk," Tara said simply, taking a step forward. "This is a digital realm, remember? The rules of physics don't necessarily apply here."

Reaching the archway, they stepped through it. A wave of energy washed over them, and they found themselves in a vast chamber filled with swirling light.

In the center of the chamber, floating on a pedestal of digital energy, was the artifact. It was a small, crystalline cube, pulsating with a soft, white light.

"This is it," Eren whispered, his voice filled with awe.

Eren's fingers brushed against the cool surface of the crystalline cube, sending a jolt of energy through his arm.

Mia's voice, warm and familiar, filled their minds once more.

"I found it during a mission years ago," she explained, her voice echoing with a hint of nostalgia. "Hidden within an ancient temple, buried beneath layers of forgotten history. It took me years to decipher its secrets, to understand its true purpose."

"And what is its purpose?" Eren asked, his voice barely a whisper.

"It registers consciousness," Mia replied. "Not just thoughts or memories, but the very essence of a being. I believe...I believe that when I was taken, a part of me, my consciousness, was imprinted on this artifact."

Eren's heart pounded in his chest. "So, if we can understand the artifact, we can find you?"

"Yes," Mia's voice confirmed, a flicker of hope resonating within her words. "But be warned, Eren. The artifact is powerful, and its secrets are jealously guarded. The path to understanding it will be fraught with challenges."

Eren looked at his companions, their faces etched with a mixture of determination and apprehension. He knew the road ahead would be difficult, but he wouldn't back down. Not now, not when he was so close to finding Mia.

---

As they stood before the artifact, a wave of energy pulsed through the chamber, and the air shimmered with digital code.

Holographic projections flickered into existence, depicting scenes from Mia's past: her childhood, her time as a corporate spy, her transformation into a Guardian of Truth.

"Mia's memories," Tara whispered, her eyes wide with wonder. "She's showing us who she is, what she's been through."

Eren watched the projections, his heart swelling with a mixture of admiration and sorrow. He saw Mia's strength, her resilience, her unwavering commitment to justice.

He also saw her pain, her loneliness, the sacrifices she had made in her fight against the darkness.

"She's been through so much," Leo said softly, his usual gruffness replaced by a rare moment of vulnerability.

As the projections faded, the artifact pulsed once more, and a new image appeared. It was a map, a digital representation of a vast and intricate network.

"The Network of the Nether," Eren whispered, recognizing the symbol from their previous encounters.

"Mia's trapped within the network," Tara said, her voice tight with urgency. "We need to find a way in."

"But how?" Leo asked, scratching his head.

Eren stared at the intricate map of the Network of the Nether, its pulsating nodes and tangled connections representing a labyrinth of digital darkness. A sense of foreboding settled upon him.

"Mia," he whispered, his voice echoing in the vast chamber. "How do we find you within this...this chaos?"

The artifact pulsed softly, and Mia's voice, a beacon of hope amidst the digital storm, filled their minds.

"Find The Shadow," she whispered. "He can guide you through the Network."

Eren frowned. The name was familiar, a name he learnt from interacting with Mia over the years. A whisper in the digital underground, a legend among hackers. "The Shadow? But isn't he just a myth, a digital ghost story?"

"He is real," Mia's voice assured him. "And he is your best chance. He knows the Network like no other. Find him, Eren. He will help you find me."

The image of the map faded, replaced by a single, cryptic symbol: a stylized shadow cast by a flickering flame. 12 Letters was etched firmly beneath the symbol.

"A password?" Eren muttered.

"This is the way for us to signal The Shadow," Tara said, her eyes gleaming with determination. "We need to find him as fast as we can!"

The digital world dematerialized in front of their eyes. In a split second, they manifested outside the crumbled warehouse.

"That was a trip," Cipher exclaimed.

"I hope... never again," Leo muttered under his breathe.
