The glacier was no longer a monument of eternal ice. It had become an open grave, carved by the destruction of magic.
Every square yard of the plateau bore the violent scars of their convergence. Deep, jagged fissures ran like black lightning through the ancient saronite bedrock, weeping foul, violet vapors where Leylin's localized thermal detonations had cracked the earth's crust.
Where the permafrost had once been smooth and merciless, there were now only jagged craters of flash-frozen slag, razor-sharp ridges of re-formed ice, and the heavy, choking soot of spent magic hanging in the thin mountain air.
The battlefield had been rewritten by the sheer volume of power forced through it. It was no longer a neutral theater of war; it was a crumbling, volatile ruin that threatened to collapse into the abyss beneath the weight of the three entities tearing it apart.
At the center of this wreckage stood Arthas Menethil. For the first time since the vanguard breached the lower gates, the Death Knight looked mortal. The absolute, unblemished perfection of his dread plate was gone.
The catastrophic blast of Leylin's environmental combustion had left its mark—a horrific, iridescent chemical burn that covered the entire left side of his torso. The silver runes etched into his pauldrons had been warped by the unimaginable heat, melted down into dull, weeping streaks of gray slag.
The heavy tattered cape that had trailed behind him like a funeral shroud was reduced to blackened fringe, smoking faintly against the sub-zero wind.
Yet, he did not bleed. He did not waver. The sapphire fire burning within the slits of his great helm remained perfectly steady, devoid of anger, pain, or malice.
It was the cold, unblinking glare of a machine that had processed the damage as nothing more than an update to its tactical parameters. He shifted his grip on Frostmourne, the runeblade's unholy hum resonating through the bones of everyone on the ridge, and took another step forward.
His boots ground the crystalline debris to powder. He was damaged, but he was entirely unbroken.
To his right, a ragged, wet gasp cut through the whistling gale. Illidan Stormrage was dragging himself back into the world of the living.
The recovery was a brutal, sickening display of raw willpower overriding a broken anatomy. His demonic chest armor had been split down the center, a deep, jagged chasm where Frostmourne's edge had tasted his essence. fel-fire, thick and erratic as spilled oil, leaked from the wound, sizzling violently as it dripped onto the blue ice below.
The emerald glow of the Skull of Gul'dan, fused into the marrow of his left hand, sputtered like a dying torch, pulsing in rhythm with his labored, shallow breaths.
He didn't rise with the graceful, predatory fluidness that had defined his ten thousand years of combat.
He rose through sheer, agonizing leverage. He forced his clawed hands against the ice, his massive leather wings flaring outward to catch the wind for stability, his muscles tearing and resetting under the frantic command of his spirit.
When he finally stood straight, his blindfolded head tilted toward the death knight, his jaw was set so tightly that blood trickled from the corners of his mouth. He was operating entirely on empty, burning through his own lifeforce to fuel the embers of his hatred.
Leylin didn't turn to look at him. He didn't need to. His comprehensive battlefield perception was already mapping the demon hunter's vital signs, calculating the precise rate of his systemic decay.
"Together," Illidan growled. It wasn't a call for cooperation born of camaraderie. It was the cold, desperate arithmetic of two survivors who understood that their individual limits had been reached.
If they fought sequentially, Arthas would systematically dismantle them, consuming their strengths one by one until nothing remained but meat for the plague. The only equation that offered a fraction of a percent of victory required a simultaneous, absolute expenditure.
"On my mark," Leylin replied, his voice flat, stripped of all emotion to conserve the focus required for what was coming.
The air between them fractured. Illidan exploded forward, leaving a trail of burning green footprints on the permafrost. He threw the entirety of his remaining mass into a terrifying, low-altitude sprint, his twin warglaives spinning in a blinding, interlocking wheel of emerald steel.
The fel-fire screaming from his blades tore through the blizzard, creating a vacuum that sucked the cold out of the air. It was a strike that bypassed all concepts of self-preservation—a mad, murderous charge intended to force the Death Knight into a singular, defensive box.
Leylin moved in the exact opposite direction. He glided backward and to the flank, his boots hovering millimeters above the ice via a constant stream of low-level arcane levitation.
His hands were already moving through the complex, rapid somatic triggers of a double-cast, his fingers weaving threads of raw mana into the ambient air like a weaver at a loom. He wasn't aiming for Arthas's armor. He was aiming for the ground beneath his feet.
The glacier directly under Arthas didn't just split—it buckled. Leylin didn't try to build a wall; instead, he seized the deep, frozen saronite crust three meters below the surface and tore it upward at a sharp, forty-five-degree angle.
The ice groaned, a massive slab of black rock and permafrost snapping like a dry twig under the sudden, immense hydraulic pressure of the arcane working.
The sudden incline caught the Death Knight mid-stride. For a fraction of a second, the perfect, immutable balance of the Death Knight was disrupted.
His right boot slipped into a hollow gap where the ice had separated, his center of gravity shifting half an inch to the left to compensate for the sudden loss of leverage.
It was the only opening Illidan needed. The demon hunter arrived like a falling meteor. The warglaives struck Frostmourne with a sound that shook the snow from the distant mountain peaks.
The kinetic violence of the collision was so immense that the newly formed stone ramp beneath them pulverized into dust instantly. Illidan's right blade parried the runeblade outward, while his left drove straight down into the joint of Arthas's right shoulder armor.
The green steel bit deep. Black, coagulated unholy fluid—the dead approximation of blood—hissed as it sprayed against the jade edge of the glaive.
Arthas didn't cry out. He didn't even blink. With his footing still compromised and his right arm partially pinned by Illidan's locking leverage, he simply tilted his head down and drove his iron-plated knee straight into the demon hunter's cracked ribs.
The impact sounded like a hammer striking a hollow barrel. Illidan gasped, his grip faltering for a split second, but he refused to disengage. Instead, he wrapped his massive, clawed wings around the Prince's shoulders, locking them together in a suffocating, visceral embrace of bone and iron.
"Now, Mage!" Illidan roared, his voice cracking as Frostmourne's pommel smashed repeatedly into his jaw.
Leylin's eyes were entirely devoid of humanity as he completed the final sequence. He had spent the last four seconds gathering every scrap of stray energy left.
He drew the residual heat from his own spent fireballs, the boiling steam rising from the cracked permafrost, and the volatile, radioactive embers of Illidan's fel-wastes.
He pulled them all into his palm, compressing the chaotic, multi-sourced energies into a single, terrifyingly stable point of absolute zero mass.
He released it in two directions at once. From the right, a beam of concentrated plasma, narrow as a needle but white-hot as the core of a star, pierced through the blizzard, targeting the weakened, scorched seam on the left side of Arthas's breastplate.
Simultaneously, from directly beneath the locked combatants, the earth erupted again—not as a solid ramp, but as a dense, high-velocity geyser of pulverized saronite and jagged ice shards, driven upward by a massive kinetic compression wave.
Two vectors of absolute force arrived at the exact same spatial coordinate at the exact same millisecond. The coordination was flawless.
The plasma beam struck the armor's weak point, flash-melting the underlying chainmail and exposing the dead flesh beneath, while the kinetic geyser from below slammed into Arthas's hip, violently throwing his lower body out of alignment with his upper torso.
The Death Knight's defensive network, optimized for singular, overwhelming frontal engagements, was forced to split its internal reserves to mitigate both disasters simultaneously.
The containment field around Frostmourne flickered. For a brief, beautiful moment, the sapphire runes along the blade went dark.
Illidan saw it.
With a final, agonizing heave, he tore his right hand free from the locking grip of the Death Knight's gauntlet. He didn't use the warglaive; there wasn't enough room for a swing.
Instead, he drove his bare, clawed fingers—infused with the absolute remainder of the Skull of Gul'dan's emerald poison—straight into the exposed, melted gap in Arthas's breastplate.
The demonic energy discharged directly into the Death Knight's chest cavity. The explosion was silent, a flash of sickly green light that illuminated the inside of the dark armor like a lantern.
The kinetic back-pressure tore Illidan away, sending his broken body rolling thirty yards across the jagged ice, his warglaives clattering into the drifts behind him.
But Arthas went down. The right knee of the Death Knight hit the glacier with a heavy, metallic thud. Frostmourne's tip buried itself deep into the ice, the Prince leaning heavily on the hilt just to keep his upper body from collapsing entirely into the snow.
The absolute, unblinking glare of his helm finally showed a tremor—the blue fire sputtering wildly, his head bowing toward the earth as the emerald poison fought against the unholy rot within his veins.
The plateau fell into a terrible, echoing silence. The wind seemed to die down, as if the mountain itself was holding its breath, waiting to see if the god could die.
Leylin did not celebrate. His hands remained raised, a fresh circle of crimson runes spinning slowly around his forearms, his analytical mind already identifying the flaw in the current silence.
The glacier was growing colder. It wasn't the normal, seasonal chill of Icecrown. It was an unnatural, aggressive drops in temperature that defied physical laws.
The ice beneath Leylin's boots began to hum, a deep, rhythmic vibration that felt like a massive heart beating miles below the stone. The frost on the nearby rocks didn't just sit; it began to grow outward in long, crystalline needles, reaching toward the center of the plateau like iron filings drawn to a magnet.
Frostmourne was drinking the mountain. Faced with the catastrophic disruption of its host's internal systems, the runeblade had bypassed Arthas entirely.
It was tapping directly into the ancient, primordial architecture of the Frozen Throne itself, drawing upon the infinite, necrotic reservoir of the Lich King's core to force its champion back onto his feet.
The blue light within the sword's guard didn't just flash; it became a blinding, vertical pillar of sapphire energy that pierced through the storm clouds above, turning the sky into a swirling vortex of ice and shadow.
Arthas's fingers tightened around the hilt. Slowly, with the agonizing, mechanical persistence of an iron crane, his knee began to lift from the ice. The melted iron of his armor began to re-forge itself, covered by a thick, translucent layer of blue glacial ice that served as a makeshift, impenetrable carpace.
Illidan was lying in the snow drift, his wings shredded, his breath a bloody mist. He couldn't move. His role in the calculation had been executed perfectly, but the math had just expanded.
"Mage..." the demon hunter whispered, his voice barely audible over the rising roar of the siphon. "The blade... break the blade..."
"I cannot break it," Leylin said aloud to the empty air. His expression was grim, his eyes tracking the massive flow of energy pouring from the peak down into the sword. "But I can only try."
He didn't fire a spell. He threw himself into the path of the siphon. Crossing the distance with a final, desperate activation of his movement working, Leylin materialized two paces away from the blinding pillar of blue light.
The sheer ambient cold of the siphon was so intense that the skin on his face began to blister and crack instantly, his eyebrows turning to white frost within seconds. If he stepped directly into the stream, his soul would be stripped from his flesh before he could complete a single syllable.
Instead, he slammed his palms against the perimeter of the energy field, his mana reserves opening like a dam.
He didn't try to block the power; he injected chaos into it. He poured raw, unrefined, highly volatile arcane energy straight into the smooth, necrotic current of the siphon.
It was like throwing sand into the gears of a precision engine. The pristine, sapphire pillar instantly turned a violent, unstable purple, the smooth hum of the mountain transforming into a horrific, screeching wail as two incompatible forms of magic tore at each other within the same space.
The siphon stuttered. The rapid re-forging of Arthas's armor stopped mid-way. The layer of glacial ice covering his chest cracked, a sharp, concussive pop echoing across the plateau as the supply of raw power suddenly dropped by eighty percent.
The Death Knight's rising momentum halted, his body freezing in a half-upright posture, his left arm shaking violently under the sudden weight of his own dead flesh.
For a single, fleeting second, the champion of the Scourge was entirely helpless, trapped between the poison in his chest and the disruption of his cure.
And in that second, the final variable arrived.
Illidan hadn't stayed down. He had used the duration of Leylin's interference to crawl, to drag himself through the soot and the blood until he was within striking distance. He didn't have his glaives.
He had only his teeth and his claws. With a final, guttural scream that sounded more like a dying beast than a night elf, the demon hunter launched himself from the snow, his hands aiming at Arthas.
He threw his weight backward, using the leverage of his entire body to rip the Prince's head back, exposing the fragile, unarmored throat underneath the chin guard.
Leylin didn't hesitate. He dropped the interference working, letting the backlash of the exploding siphon slam into his chest and throw him backward across the ice, but not before his right hand snapped forward in a final, decisive gesture.
A single, thumb-sized bolt of white-hot plasma—the absolute last drop of his available mana—streaked through the gap.
The bolt struck the exposed flesh of Arthas's throat.
There was no grand explosion. There was only a sharp, wet hiss, followed by the sound of heavy iron hitting the ground. The sapphire light within the helm didn't go out, but it dimmed down to a faint, erratic flicker, like a candle placed behind thick glass.
The Death Knight fell back onto both knees, Frostmourne slipping from his numbed fingers and clattering onto the ice, its unholy hum finally dying down into a low, pathetic whine. He was down. Truly down.
Leylin lay on his back twenty yards away, his chest heaving, his robes torn to ribbons and stained with his own blood. Every muscle in his body felt as though it had been filled with liquid lead, his mana channels burning with the agonizing ache of absolute depletion.
He managed to tilt his head up, his blurred vision scanning the ruined plateau. Illidan had collapsed across the Death Knight's legs, unconscious or dead, it was impossible to tell from this distance.
Arthas remained motionless on his knees, a hollow shell waiting for a command that was currently blocked by the ruin of his throat.
The silence returned to Icecrown. It was a heavy, suffocating thing, thick with the scent of ozone, burnt iron, and old blood.
The battle for the ridge was over. But as Leylin looked past the fallen champion, his eyes came to rest on the massive, jagged spire of ice rising directly behind them—the winding, narrow path that led upward to the apex of the world.
The Frozen Throne was still there, dark and waiting, its true master still watching from within the crystal ice.
The work was not done. But for the first time since they had stepped onto this continent, the path was clear.
