The heavy click of the reinforced chamber door sealing shut echoed like a gunshot in the sudden silence.

With Alexander, Mezos, and the Shadows gone, the cavernous room felt suffocatingly small.

It should not have.

Lab V was enormous, built around a chasm deep enough to swallow sound and light before throwing both back, distorted. The Vanguard turned below them with the vast, measured grace of something too large to belong to one person’s hands, its turbine rings dragging raw red ether through containment, crushing it into blue, refining it into white, then sending it upward through the relay spine in clean, luminous currents.

And above it, the Gate pulsed. Every pulse vibrated faintly through the metal floor and into the soles of Liam’s boots.

Liam did not move from the railing.

He kept his spine straight, arms folded tightly across his chest, staring out at the impossible arch rather than at the man stepping off the platform behind him.

Arik’s footsteps were nearly silent.

That, somehow, made them worse.

Liam could track his approach anyway by the pressure changing in the air.

The crisp scent of warm stone and caramel and the rich, warm density of Arik’s alpha ether closed in around him, made sharper by the Vanguard’s clean output and the absence of Wrohan’s owl restraint. Gold light shifted behind him, and Liam saw its reflection stretch across his own hands where they gripped his sleeves too hard.

Arik stopped close enough that the heat of him touched Liam’s back without skin.

For a moment, neither of them spoke.

The Gate pulsed.

Gold answered gold.

"Look at me," Arik said.

His voice carried that low, commanding resonance that made Liam’s instincts react before his pride could fully intervene. It scraped over the raw edge left behind by his heat, over the memory of obeying Arik’s voice while half-delirious, over the terrible comfort of knowing that Arik had never used that obedience cruelly.

Liam forced a dry, mocking chuckle and kept his eyes on the Gate.

"I’m looking at the problem, Arik. The blueprints are—"

A hand caught his chin, the warmth of it seeping into Liam’s skin.

Arik did not pinch or squeeze. There was no pain in the grip, no violence, no impatience in the way his fingers settled beneath Liam’s jaw. But the hold was absolute in its control, and with slow, deliberate pressure, he turned Liam’s head until Liam had no choice but to meet his eyes.

Up close, Arik’s gaze was dizzying.

Gold, brightened by the Vanguard and reflected by the Gate, held Liam in a way that felt almost physical. The lingering traces of the heat still thrummed beneath everything, not a bond, not truly, but some raw biological echo that had not yet been properly buried. Liam felt it like a live wire beneath his ribs, humiliating and intimate and impossible to ignore.

"You are not going back there," Arik said softly.

His thumb brushed once along Liam’s jawline, directly over the place where the ghost of Felix’s old blow had long since faded from sight.

Liam’s breath caught.

Arik noticed.

"Not to his archive," Arik continued. "Not to his manor. Not to any corridor where Felix Canmore can stand close enough to touch you again. You will never be anywhere near that man alone."

The possessiveness in the words struck like heat.

That utter, arrogant certainty set off an instant flare of irritation in Liam’s chest.

He wrenched his chin out of Arik’s grip.

Arik let him.

Liam did not step back because he could not. The railing pressed cold and solid against his spine, and Arik occupied the space in front of him with the calm inevitability of a closing door.

"I am not a child, Arik," Liam snapped. "And I am certainly not one of your obedient Agaron subjects. You don’t get to issue decrees to me."

"I am not issuing a decree as a prince."

Arik stepped closer.

Completely into his space now.

He placed both hands on the railing on either side of Liam’s hips, caging him against the metal without touching him anywhere else.

The golden ether coiling around Arik’s shoulders flared once, brushing Liam’s skin like warm velvet.

A shiver betrayed him, slipping down the back of his neck before he could stop it.

Arik’s eyes darkened.

"I am telling you as a man who knows exactly what kind of monster Felix is."

Liam’s jaw tightened.

Before he could answer, Arik tilted his head slightly, close enough that the warmth of his breath brushed against Liam’s temple and the shell of his ear.

The movement was slow, intentional, and intimate enough that Liam’s pulse jumped before pride could suppress the reaction.

"Felix’s pheromones are poisonous under special conditions," Arik said quietly. "Let me send Shadows for the blueprints."

Liam’s breath caught for a second, realizing that Arik sounded dangerously close to losing patience.

Liam could hear the strain beneath the control, the possessiveness wrapped around restraint so tightly it had begun to become dangerous.

"I know what Felix’s pheromones do," Liam replied, forcing steadiness into his voice. "I grew up in that house."

Arik’s hand tightened fractionally against the railing beside Liam’s hip.

"That is precisely the problem."

The Gate pulsed behind them.

Gold flashed softly through the dark steel veins, bathing the edges of Arik’s face in warm light. Up close, the Crown Prince of Agaron looked almost unreal beneath it: sharp gold eyes, dark hair, and ether curling against his skin like obedient flame.

Liam hated how beautiful he was when angry. Or protective. Or both.

"I am not fragile," Liam said again, quieter this time.

Arik turned his head slightly.

Their faces were suddenly too close.

Liam became painfully aware of every breath between them, every flicker of ether brushing against his skin, and every instinct that didn’t have the excuse of being in heat anymore.

"I know," Arik murmured.

The answer skidded over Liam’s mouth.

"Then stop looking at me like I’m about to break."

Arik’s gaze dropped briefly to Liam’s lips before lifting again.

"That is not what I think when I look at you."

The atmosphere tightened instantly. Liam’s pulse stumbled hard enough to annoy him.

The Vanguard hummed below them. The Gate pulsed behind them.

Gold ether curled around Arik’s throat and shoulders like a living crown.

And Liam suddenly realized, with the horrifying clarity of an intelligent man making terrible decisions, that Arik had him pinned against a railing while looking at him like this and was still holding himself back.

Liam’s fingers left the railing.

For one suspended second, his hands hovered between them, unsteady despite the stubborn set of his jaw. Then they settled on Arik’s lowered shoulders.

The fabric of Arik’s shirt was warm beneath his palms. Solid muscle tightened beneath his hand, tension coiled so tightly Liam could feel the effort it cost Arik to stand still.

Arik’s shoulders dipped by a fraction.

That small movement did more to Liam than any command could have.

The space between them collapsed into heat, gold light, and the lingering echo of Liam’s own instincts still remembering Arik’s voice from the heat. Liam rose on his toes, eyes locked on Arik’s until the last breath before contact.

Then he kissed him.

Arik went still.

Only for a heartbeat.

Then his mouth responded to Liam with startling tenderness.
