POV Sophia Reyes:

Sophia followed Seraphin through the stone corridors, her every step echoing ominously. Lyra walked beside her, unusually silent.

The atmosphere within the walls of Arboris was heavy, almost oppressive. The usual murmuring had ceased, as if even the walls were awaiting the verdict of an unseen court.

"Seraphin, how long has it been since you noticed this breach?" asked Sophia, breaking the silence.

"Only a few hours. But I didn't want to alert everyone without your confirmation," Seraphin replied, his expression grave. "If Arboris' defenses are truly compromised, it could mean the city has already been infiltrated much deeper than we thought."

Sophia nodded, her heart pounding. She had spent years perfecting the protective spells that surrounded Arboris. The thought that someone could have bypassed them filled her with a dull anger mixed with growing concern.

Finally, they reached the room Seraphin had led them to. It was a secret chamber, hidden deep within the city, known only to a few members of the Committee.

The walls were covered with ancient symbols, carved into the stone by generations of wizards who had protected Arboris before them. Sophia raised her hand, feeling the magic vibrate in the air.

"Show me the rift," she said, stepping forward.

Seraphin pointed to a precise spot on the eastern wall. At first glance, there was nothing unusual about it, but Sophia approached and touched the cold stone. She closed her eyes and focused on the flow of energy around her.

For a moment, everything seemed normal, but then she sensed a distortion, a subtle tear in the fabric of magic that protected Arboris.

"It's here," she murmured. "Someone has altered the symbols... but it's almost imperceptible. Only a wizard of advanced skill could have done this."

Lyra, who had been silent until then, also approached, her blue eyes scanning the wall intently. "This isn't just simple sabotage. It's designed to look natural, like wear and tear over time... but it's a lie. It's recent."

Sophia nodded. She knew Lyra well enough to trust her keen observation skills, despite her usually easygoing demeanor.

"Whoever it is," Sophia continued, "they've managed to penetrate our defenses by creating an almost invisible breach. This means they know our defenses better than anyone."

Seraphin frowned. "It also means they must have access to very specific knowledge... something only a few people here possess."

A heavy silence fell over the group. The thought that one of their own might be responsible for this betrayal weighed heavily on them. Sophia felt the net closing around her. If she didn't find the source of this infiltration soon, Arboris might fall, and with it, everything they had sworn to protect.

A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.

She straightened, her resolve hardening under the weight of the decision she knew was necessary. "Seraphin, Lyra, we must act quickly. It's too dangerous to leave this breach unguarded. I'll reinforce it temporarily, but we need to identify the traitor before they have a chance to strike again."

Sophia closed her eyes and muttered ancient incantations, weaving new spells around the rift. Magic pulsed through her, spreading through the stone and symbols, strengthening the weakened defenses. After a few minutes, she opened her eyes, a determined glow shining in them.

"It will hold for now," she said, turning to Seraphin and Lyra. "But we must find the source of this betrayal before it gets any worse."

"What do you suggest?" asked Lyra, her tone serious once more.

Sophia took a deep breath. "We go back to the committee meeting. I need to pretend I don't know anything so I can observe their reactions. The traitor will reveal themselves if they think we're still in the dark."

Seraphin nodded, his expression grave. "And if they don't reveal themselves?"

Sophia exchanged a glance with Lyra before answering. "Then we'll have to take more radical measures."

They left the secret room and made their way back to the meeting hall. The atmosphere in Arboris seemed to grow heavier with each step. The weight of possible betrayal hung over them like a dark cloud.

When they returned to the meeting room, the committee members were waiting, anxiety etched on their faces. General Tarkin turned to them as they entered.

"Did you find anything?" he asked, his eyes narrowing with concern.

Sophia shook her head, keeping her expression neutral. "Nothing unusual to report," she lied, her tone perfectly controlled.

Relief spread across the faces of the others, but Sophia knew this was far from over. She took her place at the table, watching each member of the committee with rapt attention.

Who could the traitor be? General Tarkin, with his uncompromising manner? One of the silent mages who had barely spoken since the meeting began? Or someone else, hiding in the shadows, waiting for the right moment to strike?

Lyra, sitting next to her, maintained a relaxed expression, but Sophia could sense the underlying tension in every fiber of her being. She, too, understood the gravity of the situation, Sophia thought.

The discussions continued, but Sophia remained vigilant, watching for the slightest sign of duplicity. Throughout the meeting, she noticed small details—exchanged glances, meaningful silences, slightly trembling hands. But nothing conclusive enough to unmask the traitor.

Finally, General Tarkin ended the meeting. "We must remain vigilant. Until we are certain of the mole's identity, each of you is under surveillance. Be careful."

The committee members rose and quickly dispersed. Sophia remained in the empty room for a moment, contemplating her next move. She turned to Lyra, who was waiting for her at the door.

"We don't have much time," Lyra said, her eyes sharp.

"I know," Sophia replied. "We need to get back to headquarters. There's still so much to do to protect the city."

They left the room, their minds heavy with dark thoughts. But before they could go any further, there was a thud in the distance, followed by an explosion. The ground beneath their feet shook violently, the walls vibrated, and a shockwave hit them full force, throwing Sophia and Lyra against the corridor walls.

Sophia felt pain explode in the back of her skull as she hit the ground, her vision blurring. She had managed to set up a shield to lessen the impact, but it was too little, too late.

As dust filled the air, obscuring her vision, panicked screams echoed around her. She looked around for Lyra, but all she saw was darkness as consciousness began to slip away.

'What was that?' Sophia thought as she fought the darkness before it engulfed her completely.
