The breach in the cliffs was the moment everything changed, Leylin had spent five years watching Icecrown.
Five years studying its mountains, its valleys, its frozen passes, and the vast stretches of hostile wilderness that surrounded the Lich King's domain.
He knew the western cliffs almost as well as he knew the defenses of his own settlement. Through his monitoring network, he had followed every tremor, every shift in the rock, every change in the terrain that might one day matter.
Northrend itself had provided the first layer of Icecrown's defenses long before the Lich King ever claimed the region. And now, the Argent Crusade had broken through them.
Leylin felt it before Arcturis confirmed it. The sensation came through the ground beneath his feet—a deep, violent shudder that traveled through the stone like the land itself had taken a breath.
He turned toward the west. For a moment, nothing seemed different, then the monitoring network registered the change. The cliff face had collapsed though not completely.
Whoever had planned the assault had understood that they didn't need to destroy the entire formation. They needed only a passage large enough for an army.
That was what made Leylin's eyes narrow, this hadn't been brute force. Someone had studied the terrain and they had found the weak points and struck them with precision.
"Good thinking," Leylin murmured.
The Argent Crusade had spent months preparing for this, they were no longer simply an army advancing toward Icecrown. They were an army that had learned how to attack it. That distinction mattered, then the Scourge struck.
The response came almost immediately from Scourgeholme. Leylin watched the first formations pour toward the breach. There was no confusion in their movements. No frantic redeployment. The undead were already waiting, their formations prepared before the cliff had even fallen.
Leylin's expression hardened. "Arthas knew."
He had known. Perhaps not the exact moment the breach would open, but he had known the Crusade would attempt it. More importantly, he had prepared for the moment they succeeded.
The Scourge allowed the Crusaders through. Then they closed around them, the Valley of Echoes became a trap. The same cliffs that had protected Icecrown for centuries now became walls around the battlefield.
The Crusade had entered through the only opening available, and the Scourge had positioned itself on the other side. Leylin watched the battle unfold.
The undead surged forward. The Argent forces fought desperately to maintain formation, but the geography was working against them. Every retreat became more dangerous, every attempt to advance brought them deeper into the trap.
Then the Crusade began pulling back. Slowly at first, then all at once. The forces withdrew through the breach and returned to the Argent Vanguard.
Leylin immediately sent a report south. Arthas knew the breach was coming.
His fingers paused over the communication crystal before he continued.
His response was prepared, not improvised. Any future advance into Icecrown must assume that the Lich King already knows it is coming. Surprise will not be available to us.
He sent the message, then he turned his attention back to the battlefield. The real assault was beginning.
The attack on the Argent Vanguard was unlike the first battle. The Scourge came with everything Scourgeholme could spare. Wave after wave of undead slammed against the Vanguard's defenses.
They did not attack like an army desperate for a quick victory. They attacked like an army that could afford to wait. That was what frightened Leylin.
The Scourge did not need to win immediately. They only needed to make the defenders spend themselves. One wave. Then another. Then another.
Each assault forced the Crusaders to expend ammunition, mana, strength, and blood. Every fallen defender meant another section of the wall that would eventually have to be held by someone else.
Leylin watched the pattern carefully. Then the frost wyrms arrived. His attention snapped toward the sky.
Massive undead dragons emerged from the northern clouds, their wings beating slowly as they descended toward the Vanguard. Even through the monitoring network, their magical signatures were unmistakable.
Leylin stood. "That's going to hurt."
The frost wyrms swept over the battlefield, their breath turned sections of the Vanguard's defenses into frozen death. Cannons fired upward. Paladins rushed to exposed positions. Soldiers screamed warnings as enormous shadows passed over the battlements.
Yet the Argent Crusade held, barely. Leylin watched several moments where the battle could easily have turned.
One cannon crew nearly lost its position. A frost wyrm descended too close to the walls before being driven away. A section of undead broke through the outer defenses only to be met by a wall of Light.
Alliance and Horde fighters stood beside one another despite their leaders' continued refusal to commit their factions fully to the campaign. Kndividuals had chosen to fight and that was enough. The Vanguard survived.
Leylin released a breath he hadn't realized he was holding. The Scourge retreated, the Valley of Echoes remained in Crusader hands. But Leylin didn't celebrate, A victory bought them time and nothing more.
And Tirion Fordring understood that better than anyone and he did not pause. The moment the Scourge pulled back, the Highlord ordered the breach reopened. The Crusade went through again.
This time, Darion Mograine and the Knights of the Ebon Blade led the advance toward Scourgeholme. Leylin had expected the death knights to be effective.
Watching them was something else entirely. They moved through Scourge territory with a freedom the living simply did not possess.
The undead recognized them as something close to their own.
Not allies, not exactly but not intruders either. The Ebon Blade exploited that hesitation mercilessly.
They struck command positions, they destroyed necromantic anchors. They severed the lines connecting Scourge formations to their commanders. And then the commanders began to fall. One by one.
Leylin watched each death ripple through the Scourge's forces. A necromancer's command signature disappeared, entire groups of undead suddenly became directionless.
Another commander fell. A second formation collapsed into chaos, and another. The pattern repeated, the Scourge was still dangerous. Even without their leaders, the undead could kill.
But killing was no longer enough, they could react. They could not coordinate nor adapt. Scourgeholme was losing its mind.
Leylin watched the final stages of the battle in silence. Then the fortress fell, the Crusade had taken Scourgeholme.
For the first time in years, the road deeper into Icecrown was no longer entirely controlled by the Lich King. But that was not what stopped Leylin later that evening.
It was what came next, the Crusaders' Pinnacle. Leylin stood at the settlement's northern edge and stared at it for a long time.
He had seen the formation countless times through his monitoring network. The Scourge had named it. A monument to their certainty that anyone who came this far would be destroyed.
Now the Argent Crusade stood on it, they had not merely occupied the pinnacle they had sanctified it.
Leylin understood what that meant.
Blighted land did not surrender easily to the Light. Northrend's soil had been poisoned by years of necromantic power. The corruption was not something lying on the surface waiting to be washed away. It had become part of the land.
To cleanse it required enormous effort. Discipline. Power. And people willing to stand there long enough for the Light to take root.
The Crusade had done it and now they were building a fortress. Justice Keep. Leylin stared at the construction. Stone rose from ground the Scourge had once considered untouchable.
Defensive walls were already taking shape, workers moved beneath the protection of soldiers. The sound of hammers carried across the frozen air.
A keep, inside Icecrown. Leylin almost smiled. Instead, he reached for a communication crystal. His first message went to Liadrin.
They held the pinnacle and sanctified the ground. I know what that cost. Make sure the people responsible understand that their work has been seen and understood. What they accomplished there is not a small thing.
He sent it, then he contacted Alleria. This message was different, more careful.
The Crusade is inside Icecrown. Not at the citadel yet, but inside its defenses. Scourgeholme has fallen, and Justice Keep is being established on the pinnacle.
Leylin paused. His eyes remained fixed on Icecrown Citadel. The corridor to the citadel is still closed. But it is closer to open than it has been since the Wrathgate.
He hesitated before adding the part that troubled him most. Arthas has not committed the full strength of the citadel.
That bothered him, the Lich King had lost Scourgeholme. He had lost the Valley, he had allowed the Argent Crusade to establish a fortified position inside Icecrown. And still, he had not unleashed everything he possessed. Why?
Leylin continued. He is watching. He stared toward the enormous silhouette of Icecrown Citadel. The question is when he decides Justice Keep has become too dangerous to tolerate.
His hand remained above the crystal. Then he added one final line. I don't know the answer. I am watching for it.
He sent the message, silence returned. Arcturis returned that evening. The spirit bear emerged from the darkness and stopped beside Leylin.
Leylin lowered himself onto a stone near the cave's edge. For a while, neither of them moved. The wind swept across the frozen ground. Far to the north, Icecrown Citadel stood against the sky.
Five years, Leylin had spent five years watching that fortress. Five years since he had returned the Helm to Arthas. Five years since he had made the decision that had changed the balance of the world.
At the time, it had seemed simple. A Scourge with a ruler was better than a Scourge without one. Arthas could be watched. Measured. Predicted.
Without him, the undead armies might have splintered into something far worse. That had been the calculation. But calculations always had consequences.
And now those consequences were marching toward Icecrown. The Argent Crusade. The Knights of the Ebon Blade. Tirion Fordring. Darion Mograine. And now Justice Keep.
A fortress built on land the Scourge had believed would never be taken. Leylin looked toward the citadel, somewhere inside those frozen walls, Arthas was watching the same battlefield.
Perhaps he was studying Justice Keep. Perhaps he was studying Tirion. Perhaps he was studying Leylin. Or perhaps he was simply waiting.
That thought unsettled him more than anything else. Because Arthas had always been patient when patience served him. And now the Lich King had been pushed farther than he had been in years.
Eventually, patience would become something else. Leylin pulled his coat tighter. "What are you waiting for?" he whispered.
The citadel gave no answer, only the wind. Only the distant roar of something enormous moving beneath the mountains. He had spent five years waiting for the moment when Arthas's patience finally reached its limit.
That moment had not come. Not yet. But Justice Keep had changed the equation. And new variables had a way of forcing even the most careful calculations to change.
Leylin looked north again. Icecrown Citadel remained motionless against the horizon. And somewhere inside that fortress, the Lich King was waiting too. The difference was that Leylin no longer knew which of them would move first.
