The top of the Lower Spire had a different quality from the floors below. It wasn't simply more of that deepening. It was the qualitative shift of a space that had been built with a different purpose from the lower floors — not garrison and checkpoint, but the immediate approach to what the citadel was actually for.
The door of the chamber was enormous and have a bit of red. Not decorated red — saturated red, the ambient quality of a space soaked in blood-adjacent power, the Lich King's necromantic architecture here having been specialized toward the particular death magic that operated through blood rather than simply through death in the general sense.
Leylin kept observing and simultaneously, adjusting his assessment of what the chamber's threat profile would require before he had finished crossing its threshold.
Deathbringer Saurfang stood at the door of chamber's center. He was large in the way that orcs who have been touched by something beyond their original nature were large — not simply the impressive physical scale of orcish physiology at its most developed, but the augmented quality of something that had been given power beyond what the body had originally been built for and that had reorganized itself around that power.
The armor was the Lich King's work. The runes burning across it were the Lich King's work. The blood-red quality of the power radiating from him was the Lich King's most concentrated investment in a single instrument.
The eyes were vacant in a way that the garrison undead were not vacant — not the simple emptiness of things operating on directed impulse without individual will, but the total vacancy of someone who had possessed a will and had had it entirely subsumed.
Whatever Dranosh Saurfang had been before the Wrathgate's exchange with Arthas had ended him, what stood in this chamber was only the shell of that person, inhabited entirely by something else. The voice came from everywhere the armor touched.
"Things are about to get much worse. Come, taste the power that the Lich King has bestowed upon me!"
Leylin was already reading the combat problem before the declaration finished. He knew about Deathbringer Saurfang's new power was a combat problem organized entirely around the blood power that the Deathbringer accumulated — a resource that built toward catastrophic expressions and that built faster the more that was given to it to work with.
The Boiling Blood arrived first — the spell working that targeted his form and began the blood drain in the pressured, relentless way of a necromantic working designed not to kill instantly but to build the power in the caster at the target's expense.
He felt it as a pulling quality — something reaching into his circulatory system through the blood-magic's specific channel and drawing on what it found there. He addressed it with water.
Waterbending's relationship to living biological systems was something he had been developing across a long time — the understanding that water was not simply the environmental element it appeared to be from the outside but the medium through which living things were most fundamentally continuous, and that someone capable of working water with precision could work through that medium in ways that extended far beyond moving water around.
He directed his own circulatory system against the Boiling Blood's draw with the counter-working of waterbending applied internally — not blocking the draw, which would have required more sustained force than the combat's other demands allowed, but redirecting what the draw was pulling in ways that fed it less power than the draw's mechanism expected.
The Boiling Blood gained. But it gained less.
He moved. Arcturis had already been reading the engagement from the moment they crossed the threshold, the spirit bear's ambient awareness of the chamber's energy distribution giving it the comprehensive picture that the bond communicated in the direct way.
The bear understood what the engagement required without Leylin directing it — understood that the Deathbringer was a kiting problem, that the blood-power accumulation the encounter was organized around required constant management of what was feeding it and how fast, that the most effective contribution the spirit bear could make was not direct damage but the management of the Deathbringer's attention and positioning.
Arcturis moved into the Deathbringer's path with the deliberate quality of something that was making itself the most immediate relevant threat — not attacking recklessly, but positioning with the precision of something that understood the tactical logic of drawing attention and was committing to it completely.
The Deathbringer turned to track the bear. Leylin built the first working in the space the turn created. Ice — but not the simple frost magic of the mage tradition's basic toolkit.
The waterbending combined with the frost working in the way that the two approached the same problem from different directions and found, in the combination, something that exceeded what either produced alone.
The waterbending's molecular-level precision directed the frost working's thermal extraction at the structural components of the Deathbringer's blood power rather than at the physical form it was housed in.
Ice formed inside the blood-magic's channeling structure, in the locations where the power moved from the armor's runes into the combat expressions — not visible ice, not the dramatic, external manifestation of frost magic, but the specific, internal crystallization that disrupted the channeling mechanism at its most vulnerable point.
The Rune of Blood's drain slowed. He followed the ice with air. The airbending he had been developing was not the dramatic, storm-scale working that the term implied when applied without the combat-applicable precision he had been cultivating.
It was the targeted manipulation of atmospheric pressure at the immediate scale of the engagement — the air between himself and the Deathbringer, compressed and directed in the precise, focused way that concentrated air pressure could interrupt magical channeling the same way physical impact could, without requiring the physical vulnerability that impact also required.
The Rune of Blood's expression discharged outward rather than inward under the atmospheric disruption. Not a complete prevention.
A partial disruption that bought what partial disruptions bought — time, and the tactical space that time created. As the Blood Beasts had been summoned.
He had been waiting for them through what he knew— the necromantic working that the Deathbringer activated at regular intervals, pulling blood-animated constructs from the ambient power in the chamber and sending them toward the living things in the space.
They were fast, and they were organized around a fixation mechanism that made them dangerous in ways that ordinary undead were not — not the mindless forward pressure of standard Scourge forces, but the targeted pursuit of blood-scent that gave them the quality of hunters rather than soldiers.
They came from the chamber's edges, five of them, already accelerating toward his position with the increasingly rapid quality of constructs whose fixation had found its target and was expressing through motion.
He did not fight them at range. He moved toward them. This was the counterintuitive decision that the engagement's blood-power mechanic required — fighting Blood Beasts at range fed their fixation mechanism with the reactive pattern that the mechanism was designed to exploit, the distance creating the building urgency that powered the acceleration.
Meeting them at middle distance with the full, immediate expression of everything available disrupted the fixation before the acceleration had fully committed.
Fire met the first Blood Beast at the range where fire was most effective against the biological construction of a blood-animated entity — close enough for the thermal working to reach the animating mechanism rather than simply burning the surface, far enough that the beast's physical impact was not yet an immediate factor.
Air hit the second while the first was still processing the fire — not the same working, not the simple repetition of an approach, but the different application of available bending to a second target whose fixation had taken a slightly different approach vector than the first.
The concentrated atmospheric pressure hit the Blood Beast's animating mechanism from the specific angle that the approach vector created, the disruption arresting the fixation mid-acceleration in the complete way of a mechanism that had been interrupted at its organizing principle rather than simply slowed by external resistance.
The other three reached him. He took the impact — controlled, managed, the deliberate choice of someone who has assessed that the third contact cannot be avoided without the avoidance creating worse positioning for everything that followed, and who has therefore decided that the contact is the preferable outcome.
The Boiling Blood surged with the contact, the blood-power gaining what it gained when the Deathbringer's instruments made successful contact with living blood. He discharged the accumulated ice working immediately after.
The waterbending's internal counter-working had been building during the engagements with the Blood Beasts — the accumulated precision of an approach that worked best when it had been building for several seconds rather than expressed immediately.
The discharge arrived at the blood-power's channeling structure in the Deathbringer's armor runes with the full, concentrated force of what the buildup had produced, and the ice crystallization inside the channeling was momentarily total.
The Deathbringer roared. Arcturis had been handling it with the patient expertise of a spirit bear that had been developing its understanding of how to manage large, powerful opponents in constrained spaces across five years of Northrend ranging.
The bear's enormous form moved through the open space ahead of the Deathbringer's tracking, maintaining the optimal distance that kept the Deathbringer's attention on the bear without allowing the Deathbringer to engage at the angles where its full power was most devastating, circling with the unhurried, precise quality of something that understood exactly how much space existed between where it was and where it needed not to be.
Leylin fired through the gaps. Not at the Blood Beasts, which had been addressed — at Deathbringer directly, through the opening angles that the bear's positioning created as the kiting circuit moved the enormous orcish form through the arcs that the chamber's geography offered.
Each working arrived at the Deathbringer from the angle that the bear's current position made available, building the damage at the accumulated pace of an encounter whose solution was not a single decisive strike but the sustained application of everything available across the time that the kiting could maintain the engagement's conditions.
Fire for direct thermal impact on the armor's construction. Ice to disrupt the blood-power channeling between applications. Air to interrupt the Rune of Blood's expression when the timing allowed it. Water to counter the Boiling Blood's draw on his own biology, managing the accumulation that the contact with the third Blood Beast had fed.
The encounter was the most demanding thing he had fought in the citadel. It was also, in the clear accounting of someone who had spent five years building toward exactly this, going the way it needed to go.
The blood power's final accumulation reached its threshold. He felt it before he saw it — felt it through the close-range read of the necromantic signature in the Deathbringer's armor, the quality of power that had built to the expression point.
The Mark was coming. The catastrophic expression of blood power at full threshold — the marking of a target whose blood would feed the Deathbringer until nothing remained.
He did not let it land. The waterbending's counter arrived at the moment of the Mark's expression with the full, accumulated force of everything he had been building toward in the counter-working throughout the encounter — not the partial disruption of the Boiling Blood's drain but the total, immediate interruption of the blood-magic's expression at the critical moment of its discharge.
The ice formation inside the channeling at the discharge's originating point was precisely placed at the structural location that had identified as the blood-magic's most vulnerable point when it was at full expression rather than building toward it.
The Mark discharged into the ice. The ice simply shattered. But the Mark's target was the ice rather than his blood, and the shattered ice could not feed the Deathbringer the way blood could, and the catastrophic expression of full-threshold blood power arrived at a target that was not alive and found, in the not-alive, the worst possible outcome for a blood-feeding mechanism.
The Deathbringer staggered. Arcturis hit him from the left with the timed force of watching an opponent reach the moment when timing mattered most and arriving at exactly that moment.
Leylin released everything he had left. The combined expression of fire and air and ice and the waterbending's full, unrestrained force hit the Deathbringer at the structural vulnerabilities that the encounter's full duration had opened — not the single, decisive impact of a culminating strike, but the comprehensive, simultaneous arrival of multiple workings at multiple points, each one addressing what the engagement had spent its duration preparing for this final moment.
Time passed by and Deathbringer Saurfang fell. The chamber filled with the sound of heavy armor meeting stone, and then it was quiet, and the blood-red quality of the ambient power began its specific, slow dissipation without the animating intelligence that had been organizing it.
Leylin stood. He was standing still — harder than the Marrowgar encounter, harder than the Deathwhisper encounter, the honest communication of a body that may had spent its full available capacity across an engagement that required it and was now registering exactly what that expenditure had cost.
Arcturis moved to him and pressed the enormous spirit bear form against his side with the grounding warmth that had been the settlement's constant companion.
He stood with it for a moment. Then he heard the sound of a large group ascending the stairs behind him.
Jaina came through the passage first, because she had been setting the pace and the pace had not allowed for the cautious entry that unfamiliar upper-floor chambers traditionally warranted. She came through and stopped.
The chamber was what the chamber was — the evidence of an encounter, the enormous fallen form of the Deathbringer Saurfang, the dissipating quality of blood-power without a directing intelligence to sustain it, and one person standing at the chamber's center with a spirit bear pressed against his side and breathing in the deliberate, controlled way of someone managing the aftermath of something that had demanded everything.
Behind her, Varian stopped. Then Thrall. Then Saurfang — the High Overlord, Varok Saurfang, who had come through the passage without knowing what he would find and who had found his son's body on the chamber floor defeated, and the person who had defeated it standing breathing in the quiet aftermath.
The High Overlord said nothing. What crossed his face in the moment of seeing it was something that Jaina did not look at directly, because some things deserved privacy even in shared spaces.
Tirion Fordring came through last, and read the chamber with the comprehensive attention of a paladin and a commander, and his gaze moved from the fallen death knight to the standing mage and the spirit bear, and the expression on his face was the honest quality of someone who had been skeptical about what a lone mage could accomplish and who had been receiving, floor by floor, ascending evidence that the skepticism had been misplaced, and who had now arrived at the culminating piece of that evidence.
The Lower Spire. The Gunship Bay. Lady Deathwhisper. Lord Marrowgar. And now this. Alone. He had not quite believed it until he was standing in the chamber where it had happened, looking at the proof of it, and the proof was specific and complete and did not require interpretation.
Aminel appeared at Jaina's shoulder and looked at the chamber and looked at Leylin, and the expression she wore was not surprise — she had known this was possible, had built five years of theoretical understanding around what she had observed of his capability — but the quality of someone seeing a theoretical understanding confirmed completely and finding, in the confirmation, something that exceeded even the understanding.
Jaina looked at Leylin across the chamber.
He looked back at her. She thought about the first time she had met him, before any of this — before Quel'Thalas, before the Third War, before the Sunwell's fall and the evacuation and the portal to Draenor and the long years of building and the campaign and the years spent in Northrend.
She thought about the person she had understood him to be then and the person she understood him to be now, and the distance between those two understandings was the accumulated distance of everything that had happened in between.
"You could have told us you were coming," she said.
His breathing had steadied. "I told Tyr'ganal," he said.
"Tyr'ganal told Aminel."
"Yes."
"We were in Dalaran."
"I know," he said. "I sent the message three days before I left. The timing was yours to manage."
She wanted to say something about how three days was not the same as adequate warning when the destination was Icecrown Citadel and the alone was involved. She looked at the chamber around her, at everything the chamber's evidence communicated about what alone had produced. She said nothing.
Thrall spoke instead, and his voice had the quiet quality of someone who had been reading the chamber and was now speaking directly to what he had read.
"The upper floors," he said to Leylin. "What's left."
"Three more halls," Leylin said. "And then the Lich King." Above them, the citadel continued its cold, organized dark. The summit was still ahead.
