Dragonblight was changing. Leylin felt it first through the substrate — the quality of the ground's communication shifting in ways that had nothing to do with weather or season and everything to do with what was moving across and beneath the surface.
Large forces. Multiple large forces, some of them known and some of them not yet identified, pressing from opposite ends of the continent toward the center with the accumulated momentum of a campaign that had found its direction and was now committed to following that direction to whatever it produced.
He spent more time at the settlement's northern edge than he had in the prior years. The view north toward Icecrown Citadel's dark shape against the sky was the same view it had always been — the citadel growing no larger, changing no faster, than it had been changing across the five years of his watching.
But the quality of the air between him and it felt different. Like the pressurized stillness that comes before something large and inevitable finally arrives. The substrate beneath his feet was restless.
After five years of learning to read Dragonblight's geological character, he knew the difference between the ground's ordinary, deep rhythms and the ground's response to events of sufficient scale to register in the rock itself.
What the ground was telling him now was that Dragonblight had become a theater in the most comprehensive sense — not a region that battles were passing through, but a region that battles were converging on, from multiple directions, toward a single point.
Wintergarde Keep had been established while he was still compiling his assessment of the Sholazar situation, which told him something about the pace at which the Alliance was moving.
The Alliance's eastern thrust through Dragonblight was not cautious. There was a directness to it — the purposeful directness of forces that had held the line long enough to understand that holding the line was not the objective, and who were now moving toward the actual objective with everything the months of defensive fighting had taught them about how to do it.
Wintergarde itself was visible to Arcturis from certain high points in the Dragonblight terrain, and the spirit bear's ranging brought back a clear enough ambient impression that Leylin could build a picture of it.
Fortified in the comprehensive way of people who understood that what they were establishing needed to hold against serious pressure rather than simply mark a position on a map. The Alliance commanders who had chosen the site had picked well — the terrain supported the keep's defensive geometry in ways that someone who understood Dragonblight could appreciate.
He appreciated it and noted, in the same assessment, that appreciating the defensive structures was exactly what the Scourge's intelligence would also be doing.
Naxxramas's appearance above Wintergarde's vicinity removed any remaining uncertainty about whether Arthas had noticed the Alliance's eastern position.
He had been aware of Naxxramas as a concept — the floating necropolis, the Lich King's specific instrument for the kind of saturation pressure that conventional Scourge ground forces could not fully replicate. What he had not been able to predict with precision was where Arthas would choose to deploy it.
The appearance above Wintergarde answered that question, and the answer's implications for the Alliance's eastern campaign were severe.
A necropolis was not a weapon in the conventional sense. It was a presence, an atmospheric threat that occupied a region the way a very large, very hostile thing occupies any space — by making everything in that space organize itself around the fact of its existence.
The forces at Wintergarde were now operating under it, which meant every patrol, every supply run, every decision about force distribution had to account for what was hovering above.
He sent an updated assessment south within hours of the first reports confirming Naxxramas's position. The assessment was direct about what it meant and what addressing it would require.
Agmar's Hammer reached him through Roanauk, whose Taunka network had contacts close enough to the Horde's western position to provide reliable reporting.
The nerubian problem was a different order of threat from the Naxxramas situation, but not necessarily a smaller one. The Scourge's undead nerubians cutting off Agmar's Hammer from resupply routes through Azjol-Nerub's surface-accessible passages had the elegant logic of forces using terrain knowledge to neutralize an opponent's numerical advantages.
The Horde forces at Agmar's Hammer were not being attacked frontally — they were being strangled, the supply lines that kept them operational compromised in ways that frontally overwhelming them would have cost far more to achieve.
Arthas was not sending his strongest forces where the opposing armies were strongest. He was sending them where they would produce the most disruption at the least cost.
This was the concerning quality of intelligent command making itself visible in the operational choices — not the brute force application of overwhelming numbers, but the targeted application of the right tool to the right vulnerability.
Leylin had been watching this quality in Arthas's decision-making for five years. He had never decided he liked it.The dragon shrines were the development that genuinely alarmed him.
He had understood the dragonflights' presence in Dragonblight as a constant of the region's character — the shrines were not simply religious or cultural sites in the way that words like shrine sometimes implied.
They were functional anchors, points where each dragonflight's specific relationship to the world expressed itself in concentrated form, where the accumulated power of ancient beings who had been part of this world since long before any of the current crisis's parties had existed was most directly present and most directly vulnerable.
When the substrate communication started producing the signature of massive necrotic working being applied in the direction of the major shrines, he spent twenty minutes in his settlement doing nothing except thinking carefully before doing anything else.
The Lich King was going after the dragons.
Not because the dragonflights represented the most immediate military threat to his campaign. Not because disrupting the shrines would produce tactical advantages measurable in the immediate campaign.
Because Arthas was thinking beyond the current campaign and understood that the dragonflights' power was a resource that the forces opposing him could potentially draw on, and that a resource you have prevented your opponent from accessing is worth more than a resource you have simply matched.
And because undead dragons — frost wyrms, emberwyrms, the terrible application of the Lich King's raising capability to creatures of that scale and power — were something that conventional military forces were not equipped to address without significant cost.
He expanded his monitoring network's coverage toward the shrine directions and spent the better part of three days confirming what he had suspected from the substrate readings before committing the assessment to the intelligence summary he sent south.
The dragonflights are under active assault. The Scourge is raising the fallen. The resulting aerial forces represent a threat category that the current campaign planning has not fully accounted for. Immediate coordination with the dragonflights is necessary, and the dragonflights will require assistance they may not immediately request because the culture of the dragonflights is not one that finds requesting assistance natural.
He added, because the intelligence summary was the place for complete honesty rather than diplomatic restraint:
The dragonflights are also dealing with something called the Nexus War, which is stretching their resources in a direction that has nothing to do with the current campaign. They are fighting on two fronts. They need help and they are managing without asking for it and this situation will not resolve itself if left to resolve itself.
He sent it south. He did not know if the right people would read it in time to act on it. He sent it anyway, because sending it was the appropriate thing to do with accurate information, regardless of what the receiving end did with it.
The dragonflights accepted help. This was, in Leylin's private accounting, a larger development than many of the military victories the campaign had produced, because the dragonflights' cultural relationship to accepting help from mortals had never been uncomplicated, and the fact that the situation had reached the threshold where they actively accepted it rather than tolerating it or simply acknowledging it said something precise about how severe the situation had become.
The combined operations between Alliance and Horde champions and the dragonflights in addressing the shrine assault and the raised dragon problem were visible to Leylin's monitoring network as a distinct change in the magical activity in those regions — the quality of dragonflight power being expressed not defensively but in active coordination with organized mortal forces, the two very different kinds of capability finding their complementary angles rather than operating in parallel.
It worked. Slowly, expensively, with costs on both sides that Leylin's reports noted without minimizing, but it worked.
The frost wyrms and emberwyrms and magmawyrms that Arthas had raised were addressed. Not eliminated in totality — some continued to operate at the campaign's edges, a persistent threat reduced from an existential one to a manageable one through exactly the kind of combined effort that neither side could have produced alone.
The dragonflights' resources were severely strained, the Nexus War's demands compounding with the shrine defense in ways that left them less present in the campaign's subsequent development than Leylin would have preferred.
But the major assault had been turned back.
The armies were moving toward Angrathar.
He knew it before the formal reports confirmed it because Dragonblight told him — told him through the substrate, through Arcturis's ranging, through Elder Mosshorn's coastal network and Roanauk's inland contacts, through every channel his five years of building had made available.
The scale of what was moving through Dragonblight toward the Wrathgate was the largest concentration of military force he had felt through the ground since Arthas's own march through these same territories, and the direction of the movement made its destination unambiguous.
Angrathar the Wrathgate. The barred entrance to Icecrown itself. The architectural structure of the Lich King's intention that everything behind it was his and that the world beyond could demonstrate the contrary through the entrance if it chose to.
The world was choosing to.
Both factions, having established their footholds and defended them through months of brutal attrition, having dismantled the vrykul power structure and cleared Sholazar and turned back the assault on the dragon shrines and addressed the necropolis threat and the nerubian siege — both factions were done with the approaches and were moving toward the door.
He stood at the settlement's northern edge the evening that the intelligence confirmed what his own awareness had already told him, and looked at Icecrown Citadel's dark silhouette against the sky, and tried to read the citadel for any indication of what Arthas knew and what Arthas was planning.
He could not read it from here. He never had been able to read it at the level he wanted — the citadel's internal character was opaque to his monitoring network in ways that five years of effort had not fully resolved.
He knew the exterior. He knew the patterns of what came out of it. He did not know what was being decided inside it.
Arthas knew the armies were coming. This was certain. Arthas had intelligence resources that Leylin had been cataloguing for five years, and among those resources was the simple, obvious fact that a concentration of military force of the scale currently moving through Dragonblight was not something that could be hidden from anything paying attention.
The death knight would have a response prepared. This was the tension that had been building in Leylin's thinking for the past week, the quality of concern that the campaign's successes had not resolved because the campaign's successes had been happening on the periphery and the center — Arthas himself, the Frozen Throne, the full, organized weight of the Lich King's restored authority — had been watching from the center all along, absorbing the peripheral losses into its longer calculation.
The armies were approaching Angrathar.
He sent a final, comprehensive intelligence summary south. The entire picture, as complete as five years of watching had made it.
Every pattern he had identified in Arthas's decision-making. Every vulnerability he had catalogued in the citadel's approaches. Everything that might be useful to the commanders who were about to stand in front of a gate that the Lich King had built specifically to receive them.
Then he called Arcturis and set the spirit bear to ranging on the tightest circuit the bear had run since the engagement on the glacier, and he went to his settlement's northern edge and stayed there through the night, watching the citadel in the dark.
Whatever was coming from behind that gate, he intended to know it the moment it started coming. The armies were amassing at the Wrathgate. Northrend held its cold, patient breath.
