Aminel was in the middle of something complicated when the knock came.
The work she had been building for the past three hours was the kind that did not tolerate interruption gracefully — a delicate, layered analysis of the Ulduar situation's magical signature that required continuous attention to maintain without allowing the attention to influence what it was observing.
She had been doing something like holding a very full cup absolutely still while also breathing, and the knock undid that immediately.
She set the working down with the deliberate motion of someone who has made peace with the loss because the alternative was making it worse.
The Kirin Tor aide who had knocked looked at her with the quality of someone who understood that they had interrupted something important and had been sent to interrupt something important anyway because what they were carrying was more important than what they had interrupted.
"Lady Jaina sent for you," the aide said. "It's urgent."
Aminel had learned, across years of working alongside people who used the word urgent with varying degrees of accuracy, to read the specific quality of its delivery. This aide was not using urgent as a formality. They were using it as a precise descriptor.
She reached for her coat. The briefing happened in motion — Jaina meeting her at the corridor's intersection and talking at the pace they were both walking, the compressed information transfer of two people who trusted each other's ability to receive information without needing it to be arranged into comfortable shapes.
Leylin. Icecrown. Alone. Walking. Aminel absorbed each piece with the focused attention of someone for whom information processing was reflexive rather than effortful, and she arrived at the full picture approximately two sentences before Jaina finished delivering it.
"He sent word through the channel three days ago that he was leaving the settlement," she said.
Jaina looked at her sideways.
"He told Tyr'ganal and Tyr'ganal told me," Aminel said. "He said he was going to the citadel and he asked us to be available for support work if the opportunity to provide it presented itself." She paused. "He did not say when he was going. I assumed there would be more warning."
"There is slightly more warning than none," Jaina said. "He's an hour from the outer walls."
Aminel processed this and accelerated her pace slightly, not because it would help with the distance and the timing but because acceleration felt like the appropriate physical response to information of this urgency.
Rhonin appeared from a side corridor with the organized urgency of someone who had been assembling things while others had been learning about what needed assembling — a contingent of Kirin Tor mages behind him in the specific, efficient formation of people who had been given a direction and were executing it without requiring additional explanation.
He had clearly made the decision faster than anyone else in the building, which was consistent with what Aminel understood about how Rhonin made decisions.
"The Argent Vanguard is the staging point," he said, as though the conversation had been ongoing rather than just beginning. "We go there first. The Crusade's coordination channels will get us updated positioning from there." He looked at Aminel. "You're the most qualified person in this building for the magical environment inside Icecrown. I need you at the front."
She accepted this without false modesty, because false modesty in situations of genuine urgency was a luxury that the situation did not have room for.
Varian was in the adjacent chamber when the information reached him — the efficient chain of military intelligence that had delivered the scout's report and its updates to the people who needed them, moving through the Violet Citadel's various rooms in the accelerating way of information in motion.
He did not deliberate for long. "Muradin," he said.
Muradin Bronzebeard, who had been present for the tail end of the Violet Citadel meeting and who had the attentive quality of a dwarf who had survived enough dangerous situations to recognize when a new one was forming, looked up from the dispatches he had been reading.
"There's a mage walking toward Icecrown Citadel," Varian said. "Alone."
Muradin's expression moved through several adjustments in rapid succession. The first was confusion. The second was assessment. The third was the resolute quality of a dwarf who has decided that the correct response to a situation is to be in it rather than discussing it.
"What are we bringing?" Muradin asked.
"What we can assemble quickly," Varian said. "I want the best we have available. Not numbers — capability. If this person has been monitoring the citadel for five years and has decided that now is the time to go in, I want to know what he knows before we arrive, and I want capable people around him when whatever he's walking into starts happening."
The elite unit assembled in the kind of time that elite units assemble when the word has been given with genuine authority — the rapid organization of soldiers who have been selected precisely for their ability to be ready before readiness would normally be achievable.
Muradin armed himself with the practiced efficiency of someone who had been putting on equipment in preparation for dangerous situations since before Varian had been born.
He said nothing further. He did not need to. The situation had communicated everything that the words had not.
Thrall's conversation with Varok Saurfang was brief. Saurfang received the situation report with the flat, attentive quality that everything received when it passed through the High Overlord's assessment — the comprehensive reading of a veteran warrior who had been evaluating situations at this level for long enough that the evaluation was essentially instantaneous.
"You want me to lead the charge," Saurfang said.
"I want you and Garrosh to take the advance toward the citadel's outer approaches," Thrall said. "The coordinated force that the Crusade is organizing for the final assault phase needs Horde support that does not depend on Alliance cooperation, because the Alliance and I are not currently cooperative in the way the situation requires."
He paused, and in the pause was the specific, honest acknowledgment of a leader who knew exactly what his political situation was and was working within it rather than pretending it was otherwise.
"What I can provide is the best Horde forces available, moving with the Argent Crusade's coordination rather than against it."
Saurfang nodded once. Garrosh, who had been listening with the quality of someone for whom inaction was physically uncomfortable, was already moving.
Thrall followed Jaina. The outer approaches to Icecrown Citadel were quieter than they should have been.
Leylin had been reading the monitoring network's coverage of this area for five years and understood the expected density of Scourge presence at various distances from the citadel's walls.
What he was walking through was below expected density in ways that his comprehensive baseline data made immediately legible — not because the Scourge had been pulled away, but because the campaign's sustained operations in Icecrown had reduced the outer garrison's available resources to the point where the perimeter coverage that full operational capacity would have provided was no longer being maintained at full operational capacity.
The citadel was conserving. He filed this with the same automatic, continuous intelligence work that had been running in the background of everything he did for five years, and continued walking.
The stairs were visible now. Icecrown Citadel's approach had been designed with the architectural intention of someone who understood that approaches to significant structures communicated something about the structures they led to.
The stairs were enormous. Not simply large — not the proportionate enormity of grand human architecture that was large in the way of things that wanted to impress while remaining relatable. These were stairs designed by the Lich King's alien aesthetic of scale without reference to what mortal visitors might find navigable or welcoming.
He started up them. The undead appeared on the third landing. Not a patrol — a cluster of the citadel's outer garrison that had apparently been tasked with the stationary function of covering this approach point and that had assessed Leylin's approach with whatever the Scourge's garrison forces used for tactical intelligence and had determined that the correct response was engagement.
Arcturis was already moving before Leylin had completed the assessment. The spirit bear had been alongside him for five years of Northrend ranging, and five years had produced in both of them the functional understanding of each other's capability and preference that made explicit coordination unnecessary in moments where the situation's demands were clear.
Leylin had a particular relationship to close-range combat — not incompetent at it, but genuinely more effective at middle and longer distances where the combination of his mage capabilities and his bending worked at their most efficient.
Arcturis had no such preference — the spirit bear engaged in whatever range the situation placed it in with the comprehensive, unhesitating capability of something that had been operating in Northrend's contested territory since before it had found him, and that had been doing so alongside the most hostile forces Northrend produced without developing any particular anxiety about proximity.
The spirit bear went into the cluster of undead like a force of nature organized with a direction and a purpose, and what came out the other side was a cleared third landing.
Leylin walked through it without breaking pace. This was how the ascent proceeded.
At each landing where undead presence registered in his awareness — through the monitoring network's close-range coverage, through the earthbending's sense of mass above and below, through the simple visual reading of what five years of cataloguing Scourge force types had made immediately identifiable — Arcturis addressed it, and Leylin walked through what the addressing had cleared, and the stairs continued above.
He was not unengaged. On several of the higher landings, where the garrison's residual strength was denser or where the undead units were larger and more capable than the outer perimeter's standard composition, he added his own capability to what the spirit bear was doing — fire working through the cold air with the combat-applicable expression of someone who had been developing this application across a very long time, earthbending in a contained form that stair required when the application could not be the broad, terrain-reshaping variety that open glacier had permitted.
Together they moved through each encounter with the efficient quality of two things that understood their complementary capabilities and had been using those capabilities alongside each other for long enough that the coordination was not coordination but simply function.
The area below the stairs grew more distant with each landing's clearance. The citadel's walls grew closer. He thought, while climbing, about the accumulated weight of what had brought him here.
The choice on the glacier five years ago. The Helm in his hands. The cold certainty of the arithmetic and the equal certainty that the arithmetic was not comfortable.
Five years of Dragonblight — the Tuskarr elder's particular quality of patience, Roanauk's careful reports, Arcturis emerging from between two pines in the Grizzly Hills' amber autumn light, the Blue Drake Egg warm in its corner.
The intelligence summaries. The months of campaign intelligence that had shaped operations he had watched from a distance, from the Argent Vanguard's breach through the Wrathgate's catastrophe through the Death Gate's failure to the Shadow Vault and everything since.
Tirion striking the heart and finding nothing there. He had not expected to feel anything particular about that finding. He had told himself he did not feel anything particular about it.
But walking up stairs toward the citadel where the thing that had been Arthas Menethil sat on a throne made of souls, he found that the not-feeling-anything-particular required more deliberate maintenance than it should have if it were simply true.
He had given the Helm to a person who was already not a person. He had made a correct calculation about a wrong thing. The distinction mattered — not because it changed the correctness, but because it was honest, and honesty about what he had chosen was part of the responsibility of having chosen.
The stairs continued. He continued. Arcturis moved ahead onto the next landing and the sounds of clearing followed immediately — the brief violence of an encounter that was comprehensively one-sided, which was what encounters between an ancient Northrend spirit beast operating at full capability and the outer garrison's residual strength consistently produced.
He reached the cleared landing and looked up. The citadel's gate was visible above. Not close — there were more stairs, more landings, more of the accumulated distance that the citadel's approach had been designed to impose.
But visible, which it had not been from the lower landings, and visible meant reachable, and reachable meant that the five years had built to something that was not simply watching from a distance.
He walked toward the gate. Behind him, moving toward the Argent Vanguard from various starting points in Dalaran and Northrend's operational staging areas, the forces assembling for the citadel assault's final phase were in motion.
Rhonin's Kirin Tor mage contingent moved through the transport portal the Violet Citadel's network made available for Northrend deployment, arriving at the Vanguard with the organized efficiency of mages who had been doing this — repositioning rapidly in response to developing situations — for the entire length of the campaign.
Aminel stepped through the portal behind Rhonin and oriented herself immediately to the intelligence picture the Vanguard's communications center had available, the five years of shared work with Leylin's monitoring network giving her a read of the current situation that the Vanguard's own intelligence had not fully assembled.
Varian's elite unit moved through their own deployment channel — the Alliance's Northrend transport infrastructure having been developed and maintained across the campaign's full duration.
Muradin moved with the unit with the unsentimental efficiency of a dwarf who had stopped being impressed by difficult situations long ago and was now simply in the business of addressing them.
Saurfang's advance, with Garrosh's driving energy contributing to its pace, moved through the Horde's deployment channels toward the citadel's approach in the coordinated manner that Thrall's direction had organized.
Jaina and Thrall moved together — not as an Alliance-Horde partnership in the formal sense, but as two people who had been working toward the same outcome for long enough that the formalities of their respective political affiliations were the least relevant thing about what they were doing.
All of them moving toward the same point.
And ahead of all of them, on the stairs, ascending at the unhurried, deliberate pace he had maintained — Leylin, and Arcturis beside him, moving toward the gate and what waited behind it.
