The cold wasn't a wave this time; it was a blade, slicing through the vast space of the forge. From the shadows high in the latticework ceiling, a Greater Wraith descended. It was exactly as Kaelen had described: larger, denser, a swirling vortex of darkness and malevolent light that seemed to drink the very light from the air. A low, subsonic hum vibrated in Aris's bones, a feeling of profound lethargy washing over her.
"Stay back!" Kaelen barked, and then he was moving, a streak of blue fire against the encroaching gloom.
The fight was nothing like the swift, clinical extermination of the Lesser Wraiths. This was a battle. The Greater Wraith didn't just attack; it defended. It lashed out with tendrils of solidified cold that shattered against Kaelen's axe, sending shards of ice-like energy flying. Where they hit the ground, more of the strange, permanent frost spread.
Kaelen was a whirlwind of controlled fury, his every move precise and powerful. But Aris could see the strain. The Wraith's energy-draining field was affecting him. The glow of his eyes and axe seemed to dim fractionally with each close pass the creature made. He was strong, but he was fighting in a environment that was actively sapping his strength.
Aris's mind, terrified as it was, was still working. Resonance. Destructive harmonic. Her theory from moments before wasn't just academic anymore; it was a potential lifeline.
She looked around frantically. The forge was a graveyard of industry. Massive, dormant machinery, conveyors, pulleys. Her eyes landed on a huge, suspended iron hook, part of an old crane system. It was the size of a man, hanging from a thick chain.
"Kaelen!" she screamed over the roar of his fire and the Wraith's subsonic hum. "The frequency! Agitate it!"
He couldn't possibly have heard her specific words, but he caught her meaning. He risked a glance in her direction, his face a mask of effort and fury.
The Wraith took advantage of his distraction, lashing out with a particularly thick tendril of cold. It caught Kaelen on the shoulder, not a direct hit, but a glancing blow. He grunted in pain, stumbling back, and a patch of his heavy coat instantly frosted over, the fabric becoming brittle.
It was now or never.
Aris didn't have a controlled energy source. But she had physics. She ran to the wall where a large, rusted lever—likely once used to control the crane—was set. She put all her weight into it, pulling down with a desperate cry. For a heart-stopping second, it didn't budge, seized with age and rust. Then, with a shriek of protesting metal, it gave way.
High above, the massive iron hook shuddered and then began to swing on its chain. It was a ponderous, heavy movement at first, but it picked up momentum, becoming a giant, brutal pendulum.
Kaelen saw it. He understood. Instead of pressing his attack, he began to maneuver, to herd the Wraith. He used bursts of fire not to strike it directly, but to force it backwards, into the path of the swinging hook.
The Wraith, focused on the immediate threat of the Pyre Guard fire, didn't register the silent, massive object arcing towards it from the shadows.
The several tons of iron connected.
It didn't pass through the Wraith like it would a ghost. The impact was physical, a deafening CLANG that echoed through the forge. But it wasn't a conventional impact. The hook didn't smash the Wraith; it disrupted it. The violent, chaotic, kinetic energy of the swinging metal, so different from the focused magical fire, sent violent ripples through the creature's form. It was the ultimate agitation.
The Greater Wraith let out that silent, mind-screaming shriek, its form blurring, losing cohesion. It wasn't a fatal blow, but it was a catastrophic destabilization.
Seizing the opening, Kaelen lunged. His axe, now blazing with renewed intensity, cleaved through the center of the rippling mass. The blue fire didn't just burn; it consumed, unraveling the Wraith from the inside out. In a final, brilliant flash, it was gone.
Silence descended, broken only by Kaelen's ragged breathing and the slow, creaking sway of the massive iron hook.
He stood amidst the fading embers, his shoulders heaving. He turned, his glowing eyes finding Aris where she stood, still gripping the rusted lever. The frost on his shoulder was already receding, the heat of his body fighting it off.
He didn't speak. He just looked at her. The calculation was back in his gaze, but it was mixed with something new, something raw and unreadable. She hadn't just thrown a bottle this time. She had changed the battlefield. She had used the environment as a weapon, based on a theory she'd conceived minutes before.
She had not been a liability. She had been an asset.
Slowly, he walked towards her, the heat of him pushing back the residual cold. He stopped a few feet away, his gaze intense.
"That," he said, his voice rough with exertion and something else, "was not magic."
"No," Aris agreed, her own voice trembling slightly from the adrenaline crash. "It was a pendulum."
A faint, almost imperceptible smile touched his lips. It was gone in an instant, but she had seen it. It transformed his harsh features, making him look younger, more approachable, and infinitely more dangerous.
"Come on, Theorist," he said, turning and heading for the exit. "Let's go home."
The word "home" struck her with a strange force. The Pyre Guard barracks wasn't home. It was her prison, her laboratory, her fortress. But as she followed him out of the dark forge, back into the smog-choked light of Veridia, she realized that for now, it was the only place she had. And the dynamic between her and her formidable warden had just irrevocably shifted.
