Sleep inside Ulduar was different from sleep outside it. Not impossible — the ward's Light provided the protective quality that Liadrin had built into it, and the quality was genuine.
The ward worked. Sleep was possible within it. But its different when there is something out there that would creep in a moment of carelessness.
Everyone who slept did so with the compressed efficiency of experienced soldiers who had learned to take rest where rest was available and to extract from it the maximum physiological benefit that the available conditions permitted.
Leylin woke up and tinkered with the monitoring network's internal coverage having built several additional hours of data across the night — the relay's continuous operation providing the incremental accumulation of intelligence that unattended instruments produced. He read the night's accumulated data before he did anything else.
The guardian positions had not changed significantly. The corruption's ambient quality had not increased. The living presence that Arcturis had flagged was still present, still maintaining itself, still carrying the effortful quality of something that had been doing this for longer than was comfortable.
He noted all of it and began the camp's quiet restoration from sleeping configuration to active preparation.
The group prepared with the organized efficiency of people preparing for difficult things — the specific items checked in the order that experience had established as the order that produced the most complete readiness in the minimum available time.
Muradin ate mouthful since he thinks it is necessary fueling of someone who had done the honest accounting of what the day required and had determined that approaching it under-fueled was not a variable he was willing to introduce.
Thrall spent fifteen minutes at the outer edge of the ward's perimeter in the shamanic preparation practice — not meditation in the casual sense, but the active working of the shamanic channels in the attenuated, distorted environment of Ulduar's interior.
The fifteen minutes produced the calibrated understanding of a practitioner who has tested their instruments before the moment of requiring them.
Alleria and Vereese ran the their own check — the systematic confirmation that the advance route the scouting had identified.
"Clear to the first junction." Alleria reported when she returned.
"Same on the left approach." Vereese confirmed, two minutes behind her.
Leylin looked at the group. "We move," he said. The first zone's interior was what the Ninjakhan's circuit had described and was also what descriptions of places always failed to fully convey.
The Titan construction rose on every side with the organized, comprehensive quality of engineering that had been applied to every surface with the intentionality of builders who did not consider any portion of their construction unimportant.
The floors carried inscriptions. The walls carried inscriptions. The vaulted ceiling — high enough that the monitoring network's altitude readings were still updating their calibration upward — carried inscriptions in the dense quality of something that had been written by beings for whom the inscriptions were functional rather than decorative.
Tyr'ganal was reading them. Not slowing — he had developed, across the years of his scholarly career, the practiced capability of reading while moving. What he was reading produced the specific, running quality of murmured translation that reached the group as fragments.
"Instructions," he said. "Operational parameters. The inscriptions are — they are guidelines. For the constructs. Not commands in the directive sense, but the embedded operating principles that the Titans wrote into the physical environment rather than into the constructs themselves."
A pause as his gaze moved along a particular section of the wall. "Fascinating. The redundancy principle — Muradin's observation about Mimiron's construction yesterday was accurate and was, if anything, an understatement. The redundancy is built into the environment, not just the constructs. The space itself carries the backup protocols."
"What protocols?" Muradin asked.
"If a construct fails its function," Tyr'ganal said, "the environment triggers the reassignment of adjacent constructs to cover the failed function until repair is possible." He looked at Leylin. "If we engage the Leviathan and the Leviathan ceases to function before we disengage from its zone, the environmental protocol will attempt to redirect other constructs toward the gap the Leviathan's cessation creates."
"Which means speed," Leylin said.
"Which means speed," Tyr'ganal confirmed.
He built the air working while they were still approaching the Leviathan's position.
This was the decision of someone who had assessed the operational requirements of the engagement and had determined that the most valuable contribution he could make to the opening phase was not combat output — the group had combat output sufficient for what the opening phase required — but the environmental management that the engagement's most significant complication demanded.
Next was the sound problem. Ulduar's interior was a connected system. The Ninjakhan's circuit had established this not through any single dramatic observation but through the accumulated, small evidence of an environment whose various components communicated with each other in the specific, continuous way of a system built for integrated function rather than isolated parts.
The Flame Leviathan's engagement would produce significant noise — the percussive quality of a force engaging a massive mechanical construct in an enclosed stone environment was not something that could be made quiet through careful fighting. But it could be made contained.
Leylin directed the air towards the zone's ambient atmospheric medium with the precise attention of someone who was not trying to silence the combat but to create the conditions under which the combat's sound did not propagate beyond the zone's boundaries.
Not a vacuum — removing the medium entirely would have created its own, more obvious communication to anything sensitive enough to notice. More like a dampening, the organized manipulation of the air's acoustic propagation properties in the zone he was enclosing, the sound produced within it absorbed into the medium rather than transmitted through it.
The working required concentration. Not the combat-action concentration of managing an active exchange, but the sustained, continuous concentration of maintaining a working that was ongoing rather than expressed and complete.
He could fight from within the working. But not at the full, committed level of fighting that the Leviathan would have demanded as the primary opponent. He had planned for this.
"I am managing the sound containment," he said to the group as the working settled into its initial, functional state. "Which means I am the secondary line during the Leviathan engagement, not the primary. The primary combat falls to everyone else."
Muradin produced the expression of a dwarf experiencing an emotion that occupies the territory between professional excitement and honest apprehension.
"Right then," Muradin said. "Let's have a look at this thing."
The Flame Leviathan was visible before it was close. This was the absolute quality of something built at a scale that made proximity unnecessary for visibility — the construct occupied its zone, by being present in the periphery of anyone who entered the space before being present in the center of their attention.
The Ninjakhan's size estimates had been accurate and had been. It was enormous.
The mechanical construct carried the organized quality of Mimiron's engineering expressed at this scale — not the improvised, accumulated quality of something built incrementally, but the deliberate, unified quality of something conceived as a whole and executed as a whole.
The group then had a quick meeting, should they wait for the reinforcements or should they go ahead and scout for them. The group from Leylin approved on scouting ahead, while Muradin and Thrall was undecided but the went along with the group.
Leylin quickly made his work about the zone. It had not registered them yet. The sound containment working was holding. Leylin felt the working's drain — the continuous cost that was not a combat expenditure but a sustained, maintenance expenditure, the kind of cost that was easy to underestimate because it arrived gradually rather than all at once.
He allocated the appropriate attention to managing it and directed the remainder of his attention toward the engagement's ongoing development.
Alleria's signal was a gesture — the compressed communication that conveyed the entire instruction.
The group quickly dispersed into the engagement positions that the previous day's planning had identified — not silently, because nothing involving Muradin in armor was silent, but with the organized efficiency of people executing a plan.
Thrall took the left approach prepared to provide support whoever needs it while Vereese and Sylvanas took the elevated positions that the zone's geometry offered on the right flank.
The angular advantages that the Titan construction's scale created for ranged units.
Alleria moved to the point position who has identified the approach that gives the engagement the best possible opening and is executing it without the deliberation that second-guessing requires.
Muradin went straight at it. This was, in the honest accounting of Muradin Bronzebeard's engagement style, the consistent expression of how a Bronzebeard approached mechanical opponents.
Liadrin moved to the support position — the paladin function of maintaining the group's functional integrity against the construct's outputs.
Tyr'ganal was with Aminel at the relay position — the two mages maintaining the monitoring coverage of the engagement in real time, tracking the sound containment working's effectiveness against the construct's combat outputs, flagging the moments when the working's boundary was being tested.
The Leviathan registered the engagement when Alleria's first arrow struck its targeting array.
The construct's response was immediate and was the mechanical immediacy of a system that had been designed for immediate response — but the automated, protocol-driven response of engineering that had been built to proceed directly from stimulus to response without the interval that deliberation required. The turrets came around.
Leylin felt the sound containment working encounter its first significant test — the Leviathan's systems coming fully online produced the enormous mechanical sound of a siege engine at operating capacity.
The working absorbed it. Not silently — the absorption had the quality of something converted rather than eliminated, the sound's energy becoming part of the working's medium rather than propagating outward through the zone.
He pushed more of his available capacity into the boundary maintenance — the graduated response of someone who has been monitoring the working's load and has found that the load has increased and has adjusted the available input accordingly.
Muradin's hammer found the construct's near-side tread assembly. The impact produced the structural communication of significant force applied to a point that the engineer who built the system had understood was important — not immediately catastrophic, but real, the first piece of the accumulated damage that would eventually matter.
"Left tread is compromised!" Muradin said, who had hit something and was reporting what the hitting had told him about the thing he had hit.
Thrall directed a lightning working through the attenuated elemental channels. The lightning found the construct's exposed circuitry at the tread assembly's compromised point with the effective quality of electricity directed into a gap that the tread assembly's compromise had opened.
The Leviathan tilted. Marginally — the small tilt of a siege engine whose mobility had been affected at one of its four contact points, the imbalance creating the specific, observable deviation from the construct's baseline movement pattern that compromised mobility produced.
Vereese placed two arrows in the targeting array's secondary optics while the tilt's recovery required the construct's system to redistribute its attention. The targeting array's response was slightly slower on the left side.
Alleria read this immediately and moved into the left-side approach with the instinctive exploitation of the vulnerability that had just been created. She fired three arrows in a sequence that was not the rapid.
The targeting array stopped tracking left entirely. Leylin felt the sound containment working absorb the next significant output — the Leviathan's primary weapon systems engaging in response to the engagement's escalation, the construct's combat protocols directing the full expression of its offensive capability toward the sources of contact.
The primary weapons were loud. He had been expecting this — the Ninjakhan's circuit had identified the primary weapon systems and he had built the working's parameters around what their output would require.
What he had built for was sufficient. But sufficient and comfortable were different, and the working's current load was in the territory between them, closer to sufficient's ceiling than to comfortable's floor.
The capacity he was directing toward the sound containment was now the majority of what he had available. The combat output he had been maintaining at a secondary level was reduced further, the prioritization clear.
Inside the zone, the Leviathan's full combat expression met Muradin's second strike at the opposite tread assembly — the dwarf having worked around to the right side during the engagement's escalation phase understood that staying in one position against a construct of this capability was not a sustainable approach.
The right tread assembly met the hammer with the structural consequence of a system already under load encountering additional significant force at a point the system had not been designed to absorb significant force from at this angle.
The Leviathan stopped. Not completely — the construct's systems were running the protocol response to mobility compromise, the backup functions engaging in exactly the redundancy-organized way that Mimiron's engineering had been designed to produce.
Thrall directed lightning into the second tread assembly's exposed circuitry with the same, adapted precision he had applied to the first. The Leviathan lurched.
Alleria, Vereese, and Sylvanas placed concentrated fire into the weapon systems' targeting array with the coordinated, sustained quality of three exceptionally capable ranged fighters.
The array went dark. The Leviathan's combat output reduced immediately — the targeting array's cessation removing the systems' ability to direct the primary weapons effectively, the constructs' outputs becoming the automated, undirected version of what directed combat had been producing. Liadrin's Light sustained the engagement positions through the undirected outputs.
The Leviathan stopped moving. The systems cycled down in the sequential way of completing its emergency shutdown protocol — not a defeat in the dramatic sense, but the organized, prioritized cessation of a system that had reached its operational limits and was executing the shutdown that the limits required.
Silence. Real silence — not the contained, absorbed silence of the working managing the combat's sound output, but the genuine silence of the combat having concluded.
Leylin released the containment working. The effort's accumulated cost arrived immediately in the honest way of costs that have been sustained and then released.
He stood in the silence and breathed. The approach corridor beyond the Leviathan's zone was open. Ulduar's interior continued deeper. The door was no longer guarded.
"Well," Muradin said, looking at the still construct with the complicated expression of someone who has just defeated something that they also professionally respect. "Mimiron built things to last."
"He did," Leylin agreed.
"Shame about the corruption." The dwarf looked at the construct for a moment longer. "Brann's going to want a full report."
"Brann is going to want to examine it personally," Leylin said.
"Aye," Muradin said, with the fondness of a dwarf who knows his brother. "That too." The group marked the route, documented the engagement, and pressed on.
