Anub'arak lunged across the frost-heaved shelf with the thunderous, single-minded momentum of a mountain engine suddenly freed from its tracks.
Leylin moved to intercept. He did not advance with an answering roar or a cinematic flourish of steel; he moved with the unhurried, terrifying efficiency of an executioner stepping up to a chopping block.
He directly blasted the Crypt Lord with blasts of fire, then with a wave of his hand fire erupted from below raising Anub'arak a few meters above the ground. And as soon as he fell, he was then met with ice spikes from the ground.
The giant Crypt Lord was dazed from all the bursted firepower. Its thick carapace saved it from getting killed in one combo. Thinking that the human couldn't penetrate its defenses.
Avoidance did not exist within Anub'arak's mind. For a king who had spent centuries crushing rivals beneath the subterranean vaults of Azjol-Nerub, the standard solution to an impediment was simply to flatten it.
He just charged right through with his massive, armored thorax by a fraction of an inch, dug his forward scythes into the blue permafrost, and pressed onward at full velocity. He expected the simple arithmetic of his mass to grind the human into grease.
Leylin declined to be gone from his path. What Leylin conjured next was a massive lump of ice from beneath the ground. Which the giant Crypt Lord tried to smash through but was stopped by it. Then continued with another massive burst of fire engulfing the Crypt Lord.
Within a few minutes Leylin neutralized the Giant Crypt Lord. He couldn't kill it directly but Leylin just threw it back far from where they currently are. Anub'arak was thrown somewhere on the undead's army, as the giant Crypt Lord landed it smashed lots of undead on its way. That was how quick the Crypt Lord's exit on the battlefield.
Leylin quickly took a look at the current battlefield. Behind him, across the area that had been turned inside out by the activation of Frostmourne and the absolute frost of Sapphiron's breath, the strike force was executing a brutal, rapid reorganization. Seeing that the unit were not in critical danger, he quickly joined backed on the battle with Arthas.
They were veterans of a dozen campaigns; they did not waste precious seconds mourning a broken line. They dealt with the world precisely as it was, not as they wished it to be.
The undead had become a different species.
This was the central, terrifying reality governing the lower apron. The powered-up Scourge units were moving with a kinetic violence that the elves' initial defensive calibrations had not factored in.
Every parry was heavier; every skeletal sprint was half a second faster. The gap between what Illidand's forces had prepared for and what the sapphire-eyed corpses were now delivering was a real, bleeding deficit that was being felt at every single point of contact across the field.
Sylvanas Windrunner executed a sharp, tactical withdrawal from her forward engagement. It was not a retreat born of panic, but the calculated disengagement of a general who recognizes that her current position is yielding a net deficit in resources.
She pulled her remaining scouts back into a tight, defensive knot, her gaze scanning the wider glacier with the comprehensive, razor-sharp focus of an officer whose entire life had been defined by the management of asymmetrical warfare.
The arcane specialists moved first to solve the crisis. Aminel and Tyr'ganal, whose perceptions had been tuned to the metaphysical currents of the mountain since their boots first touched the snow, had read the trajectory of Sapphiron's flight long before the shadow fell.
In the breathless seconds between the dragon's scream and the arrival of the frost beam, they had been driving silver anchoring spikes directly into the ley-lines beneath the permafrost.
What they had built was not a complete fortress shield—time was a luxury they did not possess—but the raw, skeletal framework of an arcane redoubt. It was a foundation upon which a real defense could be constructed, provided they could buy the minutes required to stitch the magic together.
They had held that skeleton together through the worst of the dragon's breath, their skin pale and their fingers bleeding from the immense, physiological strain of channeling raw energy against an absolute zero discharge.
"Here," Aminel rasped, her hand shaking as she wiped frozen blood from her lip. She pointed toward the glowing, triangular geometry of the anchor spikes. "This node is stable. If we consolidate the line within this perimeter, I can build a barrier that actually contains these things rather than simply dying in their path."
The unit converged upon her position with the silent, disciplined grace of professionals who recognize clarity in the middle of a storm.
Julia and Elna arrived first, their shields locked to form a small canopy over the casters; then the peripheral rangers slid through the snowdrift, pulling back from the exposed flanks; finally, Halduron and Liadrin, the heavy melee core into the center.
The new, consolidated formation took shape with the improvisational perfection that only shared competence can produce under pressure.
Alleria Windrunner was the last to drop into the circle. Her face was grim, her eyes carrying the cold, unvarnished truth of a scout who had seen the bottom of the enemy's well.
She stood at the lip of the arcane redoubt for a single beat, her gaze performing one final, systematic sweep of the surrounding ridges to ensure her assessment was complete. Then she turned to the gathered unit.
"The dead are not going to run out," Alleria said. Her voice was flat, stripped of any soft edges or false encouragement. "Not while the prince draws breath. Frostmourne has turned each corpse into a direct extension of his personal will. They are no longer drawing from a distant, weakened citadel node; they are drawing from him, and Arthas does not have a ceiling we can reach from this valley."
She paused, the wind whipping her blonde hair across her ranger's cloak.
"The battle as it is currently configured on this open ice is an absolute loss. The Scourge forces are faster, heavier, and completely immune to attrition. The area we are trying to cover is too broad to defend against an army that reproduces itself every time a body falls."
The group received the verdict with a quiet, hardened focus. There was no weeping, no frantic glances toward the path they had come. They simply accepted the new data and began looking for the next leverage point.
"We need the landscape," Vereesa said, her hand checking the tension of her bowstring. "We must force the terrain to do the heavy lifting."
"Yes," Alleria replied. Lady Vashj materialised from the smoke of the rear quadrant, her lower serpentine coils slick with black Nerubian blood.
She had been commanding an impossible rearguard action against the crypt-fiends, and her slitted eyes held the rapid, calculating intelligence of an ancient sea witch who had survived the drowning of the world.
"The geography to the northeast," Vashj said without prologue, her four hands gesturing toward a jagged ridge four hundred meters away.
She looked directly at Alleria, identifying the one elf whose cartographic memory matched her own. "There is a deep fracture in the ancient ice formations. A natural corridor. It narrows to thirty meters at its throat. The walls on either side are too steep and too densely packed for the dead to mass effectively. If we move there, they must face us in an orderly line rather than a swarm."
Alleria's mind instantly cross-referenced the coordinates against the panoramic mental map she had constructed from her high observation post.
"I know it," Alleria confirmed, her head snapping around to check the distance. "Those formations aren't natural glacier ice. They are the foundations of an ancient Nerubian outpost from the first war of the spider—old enough to have been swallowed by the frost, but structurally reinforced with saronite iron. They will not collapse under an abomination's weight."
"Thirty meters," Halduron murmured. His voice had the distinct, technical inflection of a commander who spent his life studying defiles and bridgeheads. "That is a front three people can hold. Three capable blades can lock a thirty-meter throat against twenty thousand, provided they only have to fight what is directly in front of their eyes."
"Not hold it indefinitely," Liadrin corrected gently, her hand resting on the hilt of her glowing sword. "Hold it long enough."
"Long enough for what?" Seyla asked from the rear of the circle. The question hung in the freezing air, heavy with the absolute weight of their reality.
Every arrow shot, every shield broken, and every drop of blood spilled on this glacier was ultimately in service of that singular long enough.
Alleria looked back toward the high, central dais, where Leylin's shadow was currently in battle against Arthas, and where Illidan's twin green blades were still clashing against the sapphire fire of Frostmourne.
"Long enough for Arthas to fall," Alleria said simply. "Or for the Demon Hunter to break the throne. Whichever occurs first, the moment that direct connection to the runeblade is severed, these dead will revert to a baseline state. They will return to the uncoordinated, passive state that the Lich King's crumbling authority can manage. And that... that we can butcher at our leisure."
She looked around the circle of faces.
"Or we could have Leylin change the terrain making it more advantageous to us. If we are thirty meters away, we might get surrounded by the undead easily."
The unit quickly decided and moved. Alleria then looked towards Leylin and shouted. "Leylin! Give us some ground!"
Amidst the battle with Arthas, Leylin heard Alleria's call. As he scanned the battlefield he noticed the difficulty the unit is experiencing at the moment. Then with a stomp of his foot, large ice rose from the ground making the area within Alleria's group suitable for a ranger to show its edge and returned back to the fight.
As soon as the terrain changed, they executed the movement in a continuous, rolling defensive formation. The Rangers provided a relentless grid of covering fire, their arrows creating an artificial wall of iron that kept the sapphire-eyed ghouls from closing the distance while the melee fighters escorted the fragile arcane framework that Aminel was weaving into a portable redoubt.
The Scourge followed them like a flood following a broken dam. They did not display tactical brilliance or attempt a flanking maneuver through the deep snowdrifts.
The power surging through their bones from Frostmourne did not grant them intellect; it granted them an unyielding, frantic drive toward the living flesh in front of them. They sprinted in a massive, unthinking mass, their iron boots clicking against the blue stone as they tracked the scent of elven blood.
The wide, chaotic sea of the battlefield was suddenly squeezed down into a narrow, controllable lane.
Halduron stepped into the center of the throat before anyone could assign him the position. It was his natural domain; he was the first shield of Silvermoon, and the preservation of the line was simply what he had been built to do.
Lady Liadrin stepped into the space at his right hand, her runeblade drawing a circle of golden light in the snow.
"Who takes the left?" Sylvanas asked, her bow drawn to her ear as she stood just behind the shoulder of the front line.
Elna stepped forward, her spell-breaker shield clicking against Halduron's iron rim as she took the left flank. Her face was completely expressionless—the serene, terrifying calm of a professional who has looked into the abyss, calculated the odds of survival, and decided that the duty was worth the price.
Three on the front. The terrains advantage. Against the entire northern world.
Behind them, the remainder of the unit clicked into their slots like the gears of a clock.
The rangers took the elevated ledges along the glaciers; the magisters set their anchoring spikes into the narrow dirt; Vashj's naga locked their heavy spears into the outer seams where the ice met the stone.
The first wave of sapphire-eyed ghouls tore through the snowdrift at the entrance. Halduron's sword came up.
