Footsteps converged as they ascended the summit and the cold hit them like a second wall.
They had been managing the Upper Spire's pressure since they crossed the threshold — had adjusted, had found the functional relationship with the environment that the three halls' brutal demands had forced them to develop, because the three halls had not been gentle about the development.
The Plagueworks had taken its cost. The Crimson Halls had taken its cost. The survivors who came through the final passage to the summit were capable and reduced, which was the honest description of what extended engagement through Icecrown Citadel's upper reaches produced in living forces.
Tirion came through first. He had been setting the pace since the Plagueworks — the Highlord's driving urgency of someone who has understood since the Cathedral of Darkness that time was the variable the campaign had the least of, who has not stopped moving since that understanding, who will not stop until the moving is no longer required.
He came through the summit door and saw the fight and stopped. Not from shock. From the immediate recalibration of a commander who has entered a theater and needs to read the theater before committing to it.
What the theater showed him was Leylin and Arthas. The summit chamber was enormous and was full of the layered evidence of an engagement that had been running since before any of them arrived — the earthbending's substrate work visible in the summit floor's disrupted quality, the fire's evidence in the char patterns on the ground and the thermal distortion of the air around the chamber's center, the frost's evidence in the counter-ice that had formed at angles suggesting redirection rather than impact.
Two people. The chamber between them shaped by what they were doing to it.
Arthas was fighting with the full, connected expression of the Frozen Throne's authority — Frostmourne burning with the cold blue of everything the Lich King's architecture could channel through it at this range and this connection, the death knight's movement carrying the specific, absolute quality of something that was operating at its most complete capability.
And Leylin — Leylin was managing it. This was what Tirion read, in the immediate, professional assessment that decades of command had built into how he read engagements: Leylin was managing the Lich King.
Not winning, not in the clean, decisive sense of an engagement that had found its resolution. But managing — the sustained quality of a fighter who understood exactly what they were facing and had developed, through five years of the most comprehensive preparation available, the capability required to keep the engagement from resolving in the wrong direction while maintaining the conditions for it to eventually resolve in the right one.
Jaina came through behind Tirion with what remained of the Crimson Halls group — Alleria, Sylvanas, Vereesa, Liadrin, Tyr'ganal, Varian, Muradin, Thrall, and Garrosh, accompanied by those of the Alliance elite and Horde warriors who had made it through Blood-Queen Lana'thel's encounter and the subsequent ascent.
The Kirin Tor's mage contingent was significantly reduced from its original composition. Rhonin was present, which was the important piece — Rhonin had taken damage that Jaina could read in the quality of how he moved, had taken it and had continued moving, which was consistent with everything Jaina understood about Rhonin.
Darion came through with what the Plagueworks had left of the Ebon Blade contingent — fewer death knights than had gone in, the Plagueworks' plague-based attrition having found, even in the Ebon Blade's death-adjacent nature, damage categories it could sustain and damage categories it could not fully sustain.
The survivors were the Ebon Blade's most capable, which was the dark efficiency of an encounter that eliminated the less capable and leaves what remains. Saurfang was present.
Leylin had known the High Overlord would make it through. Not because he had assessed the Plagueworks as insufficient to stop him — the Plagueworks had been more than sufficient to stop most things.
Because five years of intelligence about what had been happening in the Northrend campaign had included five years of intelligence about Varok Saurfang, and the accumulated picture of what that man was had never once produced the assessment that he was the kind of person who did not make it through.
Arthas had not stopped fighting when the others have arrived. This was itself information — the Lich King's assessment of the arriving force's immediate tactical significance registered in the specific quality of his continued engagement with Leylin, the flat, cold calculation of something that had assessed the arrivals and had determined that they were not an immediately resolving variable.
Not because the Lich King did not register them. Because the Lich King had already determined what to do about them and was in the process of doing it rather than the process of deciding.
Tirion saw this and moved forward with the Ashbringer at his side and the clear voice of someone who had been in the presence of the Lich King before and who had reached, since the Cathedral of Darkness, a clarity about the relationship between himself and what the Lich King was that stripped the interaction of anything beyond its direct, essential quality.
"Arthas." The name arrived in the summit with the chosen quality of something deliberate — not the Lich King, which was what the thing on the throne had become, but Arthas, the name of what it had been before the becoming, used here not as an assertion that the person still existed but as the specific, direct address to the presence occupying that person's form and carrying, in that form, the full weight of its own decision.
"It ends here," Tirion said. "You have consumed everything you have consumed and built everything you have built and it ends here, at the summit of what you made, by the hand of the world you tried to destroy."
The Lich King's attention shifted — not fully, not the complete reorientation of a fighter abandoning an engagement, but the partial shift of an intelligence directing its awareness toward something that had addressed it directly and that required a response.
Frostmourne's arc paused in the middle of its expression. The flat gaze found Tirion.
"So the righteous finally arrive," Arthas said, and the voice had the cold quality that it had always had and something additional beneath it — the full, resonant authority of the Frozen Throne's connection expressing itself through the death knight.
"You come to the summit of my power and tell me it ends." The flat gaze moved across the assembled group — the reduced force, the wounded, the survivors of three halls and a long ascent and five floors of the citadel's specific, accumulated hostility — with the cold, comprehensive assessment of something that had been reading its opponents' conditions since the moment of their arrival in Northrend. "You are fewer than you were."
"Enough," Tirion said.
"Enough," the Lich King repeated, and the quality of the repetition was not the quality of someone agreeing but the quality of someone testing the claim against what they knew and finding the claim insufficient in a way they intended to demonstrate rather than simply assert.
The Shambling Horrors came without further declaration. This was the Lich King's characteristic quality in moments of conflict — the absence of the dramatic escalation that living opponents often employed as a signal of increased investment, the flat, immediate translation of assessment into action without the emotional register that converted assessment into announcement.
Arthas had determined that the arriving force required addressing. The addressing began. They rose from the summit floor.
Not from outside — from within it, from the Frozen Throne's immediate connection to the necromantic architecture that saturated Icecrown Citadel at every level, the direct animation of constructs that did not need to travel from a garrison position because they were being built at the point of need from the power available at that point.
Shambling Horrors — enormous, amalgamated, the terrible quality of Scourge constructs assembled at the level of complexity that proximity to the Throne's full power enabled, each one carrying within its assembled form the augmented capability of the Lich King's most direct creations.
Three of them. Positioned between the assembled force and the chamber's center where Leylin and Arthas had been fighting.
Not random positioning — the tactical positioning of a commander who understood that three Shambling Horrors placed between his opponent's reinforcements and the engagement they were reinforcing served two functions simultaneously.
It kept the reinforcements occupied and it allowed the engagement to continue on the terms that the engagement had been on before the reinforcements arrived.
Arthas turned back to Leylin. "None of your companions will reach you in time," the Lich King said. "Witness the failure of everything you preserved."
Leylin read the tactical situation in the comprehensive way of accumulated assessment of Arthas's decision-making made possible.
The Shambling Horrors were the correct move. He would have made the same move. It was the logical response to the arriving force's composition and the engagement's current geometry — three Horrors between the group and the summit's center created the maximum disruption to the coalition's ability to coordinate while preserving the conditions that the Lich King needed to press his advantage in the direct engagement.
He addressed the advantage. The fire came with the urgency of someone who understood that the arrival of the Shambling Horrors had changed the engagement's timeline — the clock-starting quality of a development that creates a new set of conditions that the current approach needs to outrace.
He was not simply fighting Arthas at the summit. He was fighting Arthas at the summit while the coalition behind him fought three of the Lich King's most powerful direct creations, and the two fights were connected in the specific, tactical way that parallel engagements were connected when the outcome of each affected the other.
If the Horrors consumed the coalition, the summit fight changed.
He did not let himself think about this more than the thinking required for the tactical adjustment it informed. He was here. The people behind him were who they were and had survived what they had survived and were going to address the Horrors with everything the three halls had left them.
He focused on Arthas. Tirion read the Horrors' positioning with immediate, experienced clarity.
"Darion," he said.
"I see them," Darion replied, and the Ebon Blade's remaining death knights were already moving — not away from the Horrors, toward them, the aggressive repositioning of forces that had understood since the briefing that Icecrown's summit engagement would not be a simple, linear assault and who had been preparing for exactly the kind of multi-directional chaos the Shambling Horrors were designed to create.
The death knights hit the first Horror with the combined, full capability of what remained of the Ebon Blade contingent — significant, reduced, and still the most effective individual combatants in the Northrend campaign against the specific, necromantic-adjacent threat category that Shambling Horrors occupied. They were not polite about it. The Ebon Blade had not survived this long by being polite.
The Horror responded with the enormous force of its assembled construction — the amalgamated physical capability of a construct built at this level, this close to the Frozen Throne, hitting back with the weight of something that understood its function was to hold the force it was assigned to hold rather than to win an engagement on elegant terms.
Saurfang moved to the second Horror. He did not discuss this with anyone. He simply moved, in the ground-covering way of the High Overlord, and the Horde warriors who had survived the three halls read the movement and responded to it the way Horde warriors responded to Saurfang in motion — by joining the direction he was moving in, because the specific quality of what Saurfang moving toward something meant was a quality that every warrior who had operated alongside him had learned to recognize as a signal worth following.
The Horror met them with the same enormous, unhesitating force. Saurfang's blade met it with something that was, in the honest accounting of what he had just descended from having witnessed in Nagrand and every campaign since, the quality of a warrior who had decided that this specific fight was the fight that the decisions of a lifetime had been building toward, and who was fighting it accordingly.
Varian took the third. He did not consult anyone. He read the tactical situation — the two Horrors engaged, the third between the summit's far edge and the group's current position, positioned to flank either of the existing engagements if left unaddressed — and he moved, with Muradin and the Alliance elite, in the immediate way of someone who has seen the problem and has not needed more than the seeing to determine the response.
Muradin hit the Horror first, because Muradin was closer and because Muradin had been in difficult engagements with Varian long enough that they had developed the functional shorthand of fighters who know how to be useful to each other without requiring explicit coordination. The Horror staggered.
"Not a bad hit," Varian said, with the concentrated focus of a man engaging something that required his full attention and who had enough attention left over for one very short, very dry observation.
"I've done better," Muradin said. Then he hit it again.
Jaina held the center. Not fighting the Horrors — reading the full tactical picture with the Archmage's comprehensive awareness, tracking the three simultaneous engagements and the summit fight and the connections between them, identifying the moments where a magical contribution to any of the engaged positions would change the outcome in ways that waiting would not produce.
Rhonin beside her, doing the same calculation independently and arriving at compatible conclusions, the two of them representing in the center of the summit's chaos the specific, complementary quality of two extraordinarily capable mages who understood that their highest-value contribution was sometimes not the most dramatic available but the most precisely placed.
Alleria was reading the Horror engagements from elevated angles — what elevation existed, the summit providing the minimal higher ground that a ranger's eye immediately located and immediately occupied.
Her arrows found the Horrors' structural vulnerabilities with the accumulated, precise read of someone who had been firing at Scourge constructs since before the campaign began and who had developed, through that accumulated experience, the specific knowledge of where the constructs' organizing structure was most vulnerable to precisely placed physical disruption.
Sylvanas worked the same geometry from a different angle, the two sisters' fire creating the crossing pattern that filled the dead zones each individual angle left, the complementary coverage ranging separately and decades of ranging together had built into how they read a battlefield without requiring explicit coordination.
Leylin felt the engagement behind him through the observing their arrangements — felt it in the abstract way of data rather than the visceral way of direct participation, which was the functional advantage of someone who had been managing split awareness.
The Horrors were being held. Not easily. The cost was real. The holding was real. Both of these things were true simultaneously. He turned the full focus of everything available back to Arthas.
The Lich King had been pressing during the distraction — using the seconds of Leylin's split awareness to advance the engagement toward the conditions that the throne's proximity enabled the full expression of.
Frostmourne's cold was deeper now, the engagement's accumulated frost pressure having built to the point where the close-range read of his own biological state was registering the cold's physiological impact in ways that the early exchanges had not produced.
He was colder than he had been ten minutes ago. This was information. Not a problem, not yet — but the directional quality of information that was building toward a problem if the engagement continued on its current trajectory without the trajectory being changed.
He looked at Arthas. He looked at the Frozen Throne behind Arthas. He looked at everything the summit contained — the fight behind him, the three Horrors and the people holding them, the coalition's reduced but present and fighting force, the gathered weight of everything that had been moving toward this moment since before the campaign began.
He thought about what the summit required of him now. Then he moved — not back, not laterally, not the distance-maintaining repositioning that the engagement's prior phases had employed. Forward. Toward Arthas. Toward Frostmourne. Toward the decisive territory of an engagement that had been building since the main door and that the summit's convergence had moved from building toward to arrived.
Arthas met him. The summit's cold deepened. Behind him, the sound of three simultaneous fights — Ebon Blade and Horde warriors and Alliance elite against the Shambling Horrors, the combined noise of the campaign's surviving force doing what it had come here to do.
Above him, the Frozen Throne's authority pressing down on everything living in its vicinity with the full, connected weight of what it was at its most direct.
Between him and the throne: the Lich King, flat-eyed and cold and completely, absolutely the thing that everything he had done for five years had been a calculation about. He pressed forward. The summit was not done, neither was he.
