Aurelia turned her piercing gaze toward Rex, her eyes reflecting the cold hunger of a strategist who had just seen a new weapon unveiled and immediately demanded to test its limits.

"I want to see more," she said, the words carrying the weight of an ultimatum. "I want to see what happens when the predator meets something that doesn’t break like glass."

Her eyes shifted, locking onto the figure standing in the shadows. "Iris."

Iris moved. She didn’t step so much as glide into the light, her movements carrying the practiced grace of someone who had spent years managing a volatile emotional landscape.

She had been watching Rex not as a student but as an observer gauging a potential catastrophe, and now she was being summoned to confront it.

"Sparring with Rex," Aurelia commanded, her voice echoing off the blood-stained walls. "Unarmed..."

"Show me the difference between raw power and disciplined restraint."

Iris didn’t respond immediately.

She simply looked at Rex. Her gaze was unreadable, a calm surface over a deep, churning ocean of grief and calculation.

Rex walked toward her. Each footfall on the blood-slicked hardwood sounded like a heartbeat in the sudden silence of the hall.

He stopped at the precise distance where their breathing would overlap close enough to feel the heat of another person, far enough to maintain the sanctity of a confrontation.

"I have a proposal," Rex said. His voice was low, intimate, and carried a dangerous undertone that made the air between them feel charged with static.

Iris tilted her head slightly, her eyes narrowing. She watched him with the flat, careful attention of a woman deciding whether to trust a lifeline or flinch from a blade.

"Speak."

"If you spar with me and lose," Rex said, his eyes locking onto hers with unshakable intensity, "you train with me... full integration and no reservations."

"You commit to the path you have already been considering in secret."

Iris didn’t flinch at the exposure, but her pupils dilated.

"And what is the alternative?" she asked, sensing the unspoken gravity behind his words. "Why would you offer terms instead of demands?"

"Because this isn’t just about combat anymore," Rex said.

He took half a step closer, lowering his voice so that it became a private confession amidst the wreckage of the training hall. "I have been developing a workshop."

"Something I have never tested in practical application..."

"Something that operates outside the standard parameters of combat."

Iris’s entire demeanor shifted. The professional detachment wavered.

"What kind of working?"

"The soul register," Rex said.

The words seemed to freeze the air.

"Soul register?" she repeated, her voice scarcely more than a breath.

"Communication with the recently departed," Rex explained, his tone clinical despite the impossibility of the subject. "It isn’t standard magical taxonomy."

"It’s a system granted working a deep layer protocol I discovered while excavating the academy archives."

"The archives indicated the possibility existed, but the theory remained unverified..."

"I have been researching the mechanics of the connection between the physical expiration and the residual soul echo."

He paused, letting the implication settle between them like ash.

"If it works," Rex said, his voice dropping to a register of raw honesty, "I can give you one conversation."

"One single, fleeting exchange with Veylor... Not a resurrection. I am not claiming to play god."

"Nor a sustained connection, but just one moment where the veil thins enough for you to speak to someone who departed recently enough that their soul signature hasn’t yet dissipated into the ether."

Iris stared at him. For several agonizing seconds, the only sound in the hall was the ragged breathing of the wounded fighters on the floor.

Her face was a mask of controlled agony; her eyes searched his for any sign of deception, any hint of a cruel gambit.

"You cannot promise that it works," she said finally.

It wasn’t an accusation; it was a desperate plea for honesty. "You cannot promise me that the system won’t fail or that the connection won’t be empty."

"No," Rex said, his gaze unflinching. "I cannot promise success."

"But I can promise you this: the research suggests it is possible, and I intend to attempt it regardless of whether you agree to the sparring."

"The pursuit of this knowledge is my objective... The offer to you is simply... a consequence of that pursuit."

Iris closed her eyes for a moment, absorbing the brutal truth of his words. She understood perfectly.

He wasn’t using Veylor as a bargaining chip to force her hand. He wasn’t dangling a carrot to manipulate her into training.

He was describing a terrifying coincidence, two parallel paths that had suddenly, violently, collided.

"Mother," Iris said. Her voice was hollow, stripped of everything but raw need, yet she never once broke eye contact with Rex.

"The working exists," Elaris confirmed from her position against the wall.

Her delivery was flat and clinical, possessing the terrifying confidence of someone who had already examined the autopsy reports of history. "I have read documentation of it in the Nightwing household’s restricted archives..."

"It is an ancient, esoteric protocol... quite rare, technically demanding, and notoriously volatile."

"The documented success rate in historical cases is approximately sixty percent."

"Sixty percent," Iris repeated.

The number sounded like a death sentence.

"Sixty percent is not one hundred," Rex interjected, his voice cutting through the tension like a guillotine blade. "I want to be absolutely clear about that before you commit to anything."

Iris’s fingers curled into fists at her sides. "What happens in the other forty percent? What is the cost of failure?"

"Nothing happens," Rex said simply. "The connection fails to bridge."

"The soul layer remains silent, and you do not lose anything you have not already lost."

"This is not a work that can shatter what remains of your grief; it can only fail to heal it... It can only fail to make it better."

A heavy, suffocating silence descended upon the training hall. The wounded fighters on the floor seemed to fade into the background as the two central figures locked into a private war of wills.

"You did not have to tell me that," Iris said after a long moment.

Her voice trembled slightly before she steadied it. "The failure condition..."

"Most people trying to manipulate someone into a bargain leave the failure condition vague."

"They leave room for hope to blind you to risk."

"I am not trying to manipulate you, Iris," Rex said, his gaze unyielding. "I am giving you the data..."

"Whatever choice you make, I want it to be made with the same brutal honesty I am using."

Iris took a breath, a shuddering, decisive thing, and stepped into the center of the blood-slicked training floor.

Rex followed.

The atmosphere shifted instantly. The sparring that followed was fundamentally different from the massacre Rex had inflicted upon the twelve fighters moments before.

Those twelve had been a unit, a well-oiled machine of systematic instruction and coordinated technique. They were soldiers, trained to fight within the lines of a curriculum.

Iris was not a soldier. She was an assassin.

Her skills had not been forged in a classroom but in the desperate, blood-soaked margins of survival, where the only question that mattered was not whether a technique was ’clean’ but whether she would be breathing when the exchange ended.

She lacked the polished, textbook elegance of the others. Instead, she possessed something far more dangerous: a terrifying, adaptive fluidity.

She was fast.

It wasn’t the artificial, augmented speed of a system-enhanced ability; it was something more visceral. It was the honed, contextual speed of a predator that had spent years solving the singular problem of closing distance against targets who wanted her dead.

Her movement wasn’t linear; it was a series of lethal geometries.

She exploded toward him, but not from a direct approach. The floor’s geometry suggested a straight line, but Iris defied it. Her body lurched right, a feint that suggested a wide arc, before her momentum snapped left with bone-jarring force.

Rex’s Foresight screamed a warning: ’Imminent engagement in 6 seconds.’

His body reacted before her muscles had even fully committed to the strike.

He let the first exchange play out as naturally as possible, testing the waters of her lethality.

Iris fought with a calibrated, deadly intent. She lacked the frantic urgency of the desperate; she fought with the cold efficiency of someone who was deliberately preserving her options.

Every strike was a question: How do you respond to this? How fast are your reflexes here? Where is the crack in your armor?

She was probing his defenses not to break them yet but to map them. She was learning from him through violence.

And Rex was learning her.

His martial arts mastery already contained every technique Iris could possibly execute; he knew the ’how’ of her movements. What he was doing now was learning the ’why.’

He was cataloging the minute tells that no textbook could teach: the way she shifted her weight onto her left foot milliseconds before a direction change; the specific, minute tension in her jaw that signaled a maximum commitment strike; the way her pupils dilated when she spotted what she believed was an opening.

He wasn’t just fighting an opponent; he was downloading a blueprint of a killer. Every twitch, every microexpression, every heartbeat was being filed away into his consciousness, turning her into a known variable in his ever-expanding equation of war.
