"I'll choose," Caelum had said.
And then he chose fire.
The corridor erupted in a surge of heat as the flames burst from his hands—not a narrow stream nor a controlled flicker, but a wide, devouring arc that roared forward like something unbound. The air warped under its passage, stone along the walls glowing faintly red as the force of it pushed outward, filling the confined space with searing intensity.
For a moment, it felt as though the world itself bent around that flame.
The masked agent did not retreat.
A barrier formed in front of him without incantation, a shimmering dome of Protego Maxima rising in a smooth, practiced motion. The fire struck it head-on, spreading across its surface in waves of white-blue light that clung and crawled like molten oil. The shield held—but only just.
Fine fractures began to appear.
Hairline cracks spread across the surface, distorting the magic as the pressure mounted. The agent remained still behind it, his posture unchanged, his attention fixed not on the attack, but on Caelum himself.
When he spoke, there was no fear in his voice—only quiet fascination.
"Extraordinary. Your fire does not conform."
He lifted his hand slightly, reinforcing the barrier with precise control. The cracks slowed, then stabilized, the shield pulsing as it redistributed the force pressing against it.
"But raw force alone is not enough."
The barrier surged outward in response, releasing a controlled wave that shattered the incoming flames and forced them apart. The fire collapsed under the pressure, scattering into fading embers that died against the corridor walls.
The sudden loss of momentum hit Caelum hard.
He staggered back a step, breath catching sharply as the heat withdrew too quickly from his body, leaving a hollow, aching strain behind. His hands trembled faintly as the fire receded, no longer surging, no longer overwhelming—just barely held in place.
The agent moved immediately.
A hex struck the wall behind Caelum, exploding stone outward in a sharp burst that forced him to dive aside. Another spell followed, a binding curse that sizzled into the ground where he had stood a fraction of a second before. He pushed himself upright, moving again, weaving through the confined space with speed that outpaced his age, his body reacting faster than his thoughts could fully form.
But speed was not enough.
The agent did not rush. Every movement was deliberate, each spell cast with measured intent, cutting off escape paths, forcing Caelum into narrower angles, reducing his options with quiet efficiency.
A slash of magic caught him across the side before he could evade it completely. The impact drove him into the wall, pain flaring sharply as his shoulder struck stone. He dropped to one knee, breath breaking into uneven bursts as the strength in his limbs faltered.
The fire within him flickered.
Still there.
But no longer surging.
The agent approached at an unhurried pace, the pressure of his presence filling the corridor as surely as any spell.
"You were never going to win this," he said calmly.
Caelum forced himself upright, his back pressing against the cold stone wall as he steadied his breathing. Blood ran down from his temple in a thin line, his arm trembling under the strain of holding himself upright.
"You could have spared your friends," the agent continued. "Now they will watch you fall."
He raised his hand again, preparing the final spell.
For a moment, everything narrowed.
The corridor.
The distance.
The weight of the decision already made.
And then Caelum laughed.
The sound came rough at first, broken by exhaustion and strain, but it did not stop. It grew, steadying into something real, something that echoed strangely against the stone around them. It was the first time he had laughed since waking in a world that had offered him nothing but survival.
Here, at the edge of defeat, it returned.
The agent tilted his head slightly. "Is that defiance," he asked, "or madness?"
Caelum's gaze sharpened.
Caelum's eyes glinted.
Behind the agent, movement stirred.
Julian had forced himself upright, his body unsteady, one hand braced against the wall as he drew in a sharp breath. His expression was strained, not just from injury, but from something deeper—something building at the edge of control.
For a brief moment, he hesitated.
Then he spoke.
"[Hold]."
The word was not loud, but it did not need to be.
It landed.
The air in the corridor tightened violently, as though something invisible had seized hold of the space itself. The agent's movement stuttered—not completely stopped, but slowed, his body resisting in a way that was unnatural, as though the simple act of motion had become contested.
The magic resisted.
It pushed back.
The word strained under its own weight, reality itself refusing to fully accept it.
Julian's expression twisted as the backlash hit him, his breath catching sharply as the force rebounded through him. The word held—but only barely, and only for a moment.
It was enough.
The agent turned sharply, the pressure around him spiking as he broke through the restraint, his control reasserting itself with force. His hand moved, releasing a burst of magic that struck Julian cleanly and threw him back into the wall, the sound of impact sharp even through the lingering suppression of sound.
But the interruption had already done its work.
Caelum moved.
He surged forward, closing the distance in a single motion, the wand they had taken from the enforcer now firmly in his grip. He had managed to retrieve it in the middle of the chaos, concealing it until now as he waited for the one opening he knew he would never be given again.
The agent turned back—just in time to see it pointed at his chest.
"Diffindo!"
A blade of searing white light erupted from the wand and struck the agent square in the chest before any defense could fully form, draining the last of Caelum's reserves as the spell forced its way into existence. The impact split through the mask with a sharp, cracking hiss, tearing through enchanted glass and fabric alike as the force of the curse carried through.
The backlash came an instant later.
His vision dimmed at the edges, his body threatening to give way as the sudden emptiness tore through him, but he locked his stance in place, forcing himself upright through sheer will.
He would not fall first.
The fire within him had steadied again.
Julian stirred first, dragging himself forward despite the pain, his voice unsteady as he spoke.
"Is he…?"
"Gone," Caelum said quietly.
He did not look away from the body.
Not yet.
Behind him, Mara helped Talwyn sit upright, her movements careful, her expression tight with lingering fear and relief. Lina remained close, silent, watching with wide, unblinking eyes.
For a long moment, no one spoke.
Then Caelum lowered the wand.
He turned toward them, his expression composed, but something in it had shifted—something quieter, heavier, more certain than before.
"There's no going back now," he said.
And this time—
no one disagreed
