The main body of the Imperial response arrived on the morning of the eleventh day.
They arrived as Vorath had described they would: larger than the advance element, professionally organized, moving with the specific quality of an operation that had been given appropriate resources and had used the twelve days since the advance element's report to prepare those resources for the specific situation they were being deployed against. Not careless. Not aggressive in any gratuitous sense. Simply present, with the patient determination of people who had a job and the means to do it.
Oma's coherence detector gave the first reading at dawn: fourteen resonance signatures, the highest at Rank Four, three of them. The suppression specialist from the advance element was present, along with two additional specialists whose equipment signatures Oma identified from her Imperial research database as advanced echo-disruption systems, capable of interfering with multiple simultaneous contacts.
Three suppression specialists. Kael noted this and told the company.
Verath looked at the coherence detector readings and said: "They've built a response specifically for four simultaneous contacts. They know."
"They've known since the Collector," Vorath said. "The crystal bloom at the Collector site was consistent with four fragments active. The advance element confirmed and reported."
"They've had two weeks to prepare," Syrenne said. She was standing at the observation window, watching the canyon approach, in the watching configuration that was not anxiety but continuous active assessment. "And they've used it."
"The three suppression specialists working simultaneously," Oma said, with the tone of an engineer assessing a new variable. "At maximum combined output, that's approximately four times the suppression intensity of the single specialist at the first bottleneck. The counter-calibration I built for the advance element's equipment will not hold against the combined field."
"How long can the device sustain at the counter-calibration level," Kael said.
"Against the combined field? Twelve to fifteen minutes before the calibration drifts beyond recoverable range."
"Can you recalibrate in the field."
"Not for all three simultaneously. I can calibrate for the dominant frequency and accept degraded performance against the other two." She looked at her instruments. "Degraded performance against two suppression systems is approximately the same effective suppression as one system at full output, which is what the containment protocol was designed to handle."
"Which means the suppression threat is one specialist rather than three," Cassin said.
"With the remaining two as noise in the counter-calibration field," Oma confirmed. "Less than optimal. Manageable."
Kael looked at the coherence detector's display. Fourteen signatures, moving from the canyon's northern exit toward the ridge base path, spreading as they moved, the specific deployment configuration of a unit that was covering approach vectors rather than walking in column. Professional. Thorough.
"They're not coming up the path," Vorath said. He was looking at the deployment pattern with the expression of someone reading a tactical document they had helped write. "They're establishing a perimeter first. That's a containment posture, not an assault posture. They want to seal exit routes before they advance."
"How long to complete the perimeter," Syrenne asked.
"Four hours. The ridge's terrain makes a complete perimeter difficult. The community's east and west faces have service paths that don't appear on Imperial survey maps. If those paths are clear, we have exits that the perimeter won't cover."
"The service paths," Solen said. He and Ress had been listening in the silence of people who were following a conversation about their own terrain and were deciding when their specific knowledge was the relevant contribution. "The east path is clear. The west path has a seasonal obstruction that will be passable in approximately two hours." He looked at the rest of the company. "Both paths come out on the far side of the ridge, beyond the perimeter's natural extent. Neither appears on any survey I've ever seen the Empire use."
"A two-hour window before the west path is passable," Verath said. "A four-hour window before the perimeter is complete. In two to four hours, we can move."
"Where," Dara said. She asked this in the tone of a woman who was going to help them with the answer and who needed the answer to be complete before she could help.
Kael looked at the coherence detector. He looked at the development curve Oma had been tracking for eleven days. He looked at the company assembled around the table.
"The Architecture is at ninety-one percent," he said. "Two more days of practice in the inner chamber would complete it. Two more days is not what we have."
"What we have," Oma said carefully, "is nine percent of development remaining and the stabilization device at maximum counter-calibration, which accounts for approximately seven percent of the gap. That leaves two percent."
"The margin," Syrenne said.
"Yes," he said. "And the margin is what it is. It either holds or it doesn't, and I won't know which until it's required." He looked at the group. "What I know is that the Architect's projection is not the Imperial main body. The main body is the thing we need to stay ahead of until the Architect's projection arrives. We are not fighting the main body. We are surviving it."
He said this clearly, because it was the most important distinction of the morning.
"Then we move through the paths before the perimeter closes," Vorath said.
"Yes."
"Direction."
"East," Kael said. "Deeper into the Fracture Lands. Where the Echo-Blood saturation increases and the Empire's equipment becomes less reliable and the terrain becomes more challenging for a unit that doesn't know it and less challenging for people who do."
He looked at Solen. Solen looked at the ridge. He looked at Ress, the brief communication. He looked back at Kael.
"I know where we go," Solen said. "Pack quickly."
