Jax shook her awake with his flesh hand on her shoulder and his prosthetic hand already pointing at the tactical display.
"Get up. Now."
Kira went from sleep to standing in two seconds. Her body screamed. The two hours of rest had been enough to take the edge off the physical exhaustion but not enough to clear the cortisol or relax the cramped muscles. Her right arm was dead in the sling. Her left hand tingled.
None of that mattered because the tactical display was showing something that made the physical complaints irrelevant.
"The seal," Jax said.
Kira looked.
The ship's sensors had been monitoring the seal at the center of the Expanse since they'd entered. The containment architecture, rendered on the display as a spherical boundary of interlocking dimensional geometries, had been showing increasing stress since the five-pillar pulse weeks ago. Cracks. Pressure points. The Hollow King pushing against its prison.
The display now showed a tear. Not a crack. A tear. A visible rupture in the containment geometry, the dimensional fabric of the seal pulled apart at a point on its lower quadrant. The rupture was small relative to the seal's total surface area, maybe two meters across. But it was open. The seal wasn't just cracking anymore. It was breaking.
"When?" Kira asked.
"Forty-seven minutes ago. The sensors flagged it while you were asleep. I was about to wake you when the comm signal came in."
"What comm signal?"
"The Emperor."
Kira's jaw locked. She walked to the Throne. Sat down. Pressed her left palm into the armrest and let the passive interface feed her the full picture. The seal. The tear. The dimensional energy flowing through the rupture like air through a puncture in a pressure vessel. The Hollow King's presence on the other side, pressing, pushing, the entity's awareness pouring through the opening like water finding a new channel.
"Put him through," she said.
The Emperor's voice filled the Throne room. Gone was the controlled, measured tone of their previous conversations. This voice was tight. Clipped. The voice of a man who had spent four hundred years maintaining control and had just lost it.
"Commander Vance. The Ascension Platform has been activated."
Kira's hand gripped the armrest.
"Forty-two minutes ago, Director Thalion of the Platform Engineering Corps initiated a full activation sequence. He did not have authorization. He acted on his own assessment that the seal's deterioration required immediate intervention."
"The Platform feeds energy to the Throne," Kira said. "The energy goes to the weakest point in the seal. You told us this. If the seal is cracking, the energy accelerates the failure."
"I am aware of what I told you." The Emperor's voice was stripped to bone. No diplomacy. No calculation. "Director Thalion believed the Platform's energy would reinforce the seal. His understanding of the system was incomplete. The energy is not reinforcing the containment. It is flowing through the rupture and into the dimensional space beyond, feeding the entity's substrate and widening the tear."
"Shut it down."
"The activation sequence includes a four-hour safety lockout. The lockout prevents shutdown during the initial power ramp to avoid catastrophic energy discharge. The lockout was a design feature intended to protect the Platform's engineering team. It cannot be bypassed."
"Four hours."
"Three hours and eighteen minutes remaining on the lockout. When the lockout expires, I can initiate shutdown. But the damage during those three hours will be—"
"Voss," Kira said into the ship's comm. "Operations space. Now."
Voss was already there. She'd been monitoring the seal data from the operations space when the tear appeared, and she'd been running calculations for the last forty minutes. Her face told Kira everything before she opened her mouth.
"The original timeline for seal failure was measured in days," Voss said. "The tear changed that to twelve to eighteen hours. The Platform's energy input changes it again." She pulled up the data on the operations display. Numbers. Curves. The mathematics of a containment system being overwhelmed from two directions: the entity pushing out and the Platform pushing in. "Six hours. Possibly less. The Platform's energy is widening the tear at an accelerating rate. Once the tear reaches a critical width, the containment geometry cascades. The entire seal fails at once."
"Six hours," Kira said.
"At the current rate of degradation. If the entity increases its pressure, or if the Platform's energy output ramps further during the lockout period, the timeline shortens. Five hours. Four. The uncertainty range is wide because we're watching two systems interact in real time and neither one is behaving predictably."
"How long until we reach the seal?"
"At maximum speed, three to four hours. Depending on convergence zones."
Three to four hours to reach the seal. Six hours until the seal failed. That left two to three hours at the seal before catastrophic failure. Two to three hours to communicate with the Hollow King, learn its condition, get the containment data they needed, coordinate with the Emperor to redirect the Platform's energy from seal destruction to Severance weapon power, position the ship, arrange the void-touched pilots, and fire the weapon.
Kira had planned this as a sequence. Step one, then two, then three. An orderly progression. Arrive. Communicate. Calibrate. Fire. Each step building on the last.
That plan was dead.
"Everything happens at once," she said.
Cross was at the tactical console, running the numbers alongside Voss. "Commander, a simultaneous operation is, I must be direct, operationally infeasible. The communication with the entity requires Sable at full depth on the communication layer. The weapon calibration requires Voss and Aria-7 at full capacity on the Severance data. Navigation to the seal requires you in the Throne. Pillar management requires Corvin. And when we arrive, the weapon operation requires all four void-touched at interface stations simultaneously."
"Then we parallel the tasks." Kira's voice went clipped. Short sentences. The stress cadence that her crew recognized. "Sable reopens the Hollow King communication channel now. During transit. She talks to the entity while we fly. Voss processes whatever data Sable receives in real time and feeds the containment calibration to Aria-7 as it comes in. Corvin runs the pillars at maximum for transit speed. I navigate. When we arrive at the seal, Niko takes the sustainment position, Corvin manages power, Sable handles communication, and I pilot the weapon."
"And the entity's condition?" Cross asked. "The request it was forming before the channel terminated? We do not know what it wants."
"Sable finds out during transit. We have three hours of flight time. She uses them."
"The last communication session nearly overloaded her neural architecture at eighty-five percent filter capacity."
"Then Voss modifies the protocols. Wider bandwidth. More processing offload to Aria-7. Whatever it takes to keep Sable connected long enough to hear the condition and extract the containment data."
"Aria-7 is at ninety-two percent capacity processing the Severance schematics and the Platform modification data," Voss said. "Absorbing additional processing load from Sable's communication session will require reducing capacity elsewhere."
"Reduce navigation support. I'll fly by passive sense. Free Aria-7's navigation processing for Sable's communication data."
Everyone in the room stopped talking.
Flying the inner Expanse on passive sense alone. No Aria-7 navigation support. No bio-tissue sensor analysis. Just Kira's modified substrate perception, the impression-based awareness that let her feel the currents and the convergence zones without the four-dimensional precision of the combat interface.
"That is extremely dangerous," Cross said.
"Noted."
"Commander, I am not lodging an objection for the record. I am telling you that navigating the inner Expanse without sensor support or combat interface is—"
"The only option that lets us do everything we need to do in the time we have. Unless you have three extra hours in your pocket, Admiral."
Cross didn't respond.
"Emperor," Kira said into the long-range comm. "Can you hear the seal data I'm transmitting?"
"Receiving."
"The Platform's energy needs to be redirected. Not shut down. Redirected. When the lockout expires, instead of shutting the Platform down, your engineers need to reconfigure it as a focusing array for the Severance weapon. Doctor Voss is transmitting the modification specifications now. Your engineers have three hours and eighteen minutes to prepare."
"Commander, my engineers have never seen Progenitor dimensional engineering. The modification specifications are—"
"Beyond anything they've worked with. I know. But they built the Platform from void-touched neural architecture data, and the Severance operates on the same frequencies. The gap between what they know and what they need to know is bridgeable. Voss will be available for consultation through the long-range comm during the modification. Make it work."
A pause. The Emperor, four hundred years old, accustomed to being the one who gave impossible orders, absorbing the experience of receiving one.
"Understood," he said.
The channel stayed open. The Emperor's engineers would need it.
---
"Wake Niko," Kira said.
Tessa was in the operations space doorway before the words finished. "He's had four hours. Your doctor said six."
"The timeline changed. We don't have six."
"My brother—"
"Your brother is on a ship that's flying toward a seal that's breaking open in six hours, with a weapon that needs him to fire it and no time to wait. Wake him. Feed him. Get him functional. Voss, what's the minimum recovery time for interface capability?"
Voss looked at Tessa. At the operations space. At Niko's cot. The doctor fighting the commander. "With pharmaceutical support and the ship's restorative systems? He can be conscious and interface-capable in thirty minutes. It won't be full capacity. Sixty percent, maybe seventy. Enough for sustainment work but not for extended operations."
"It'll have to be enough." Kira looked at Tessa. "I'm not asking your brother to give everything. I'm asking him to give what he can. That's what I'm asking all of us."
Tessa stood in the doorway for three seconds. Her hands at her sides, the mining calluses catching the bio-tissue light. Then she turned and went to wake her brother.
"Sable," Kira said.
"Ready." Sable was already at the wall, hands positioned, the communication layer at standby depth. She'd been listening to the entire conversation and had prepared while the others talked. "Wider bandwidth protocols are loaded. Aria-7's processing offload is configured. I can open the channel and sustain it for the transit duration if the entity cooperates."
"The entity's condition. That's the priority. Whatever it was trying to tell you before the channel terminated, we need to hear it. The containment data is secondary. If the entity has a condition for consenting to the Severance, we need to know what it is before we fire the weapon."
"And if the condition is something we can't meet?"
"Then we fire the weapon anyway and we deal with the consequences."
Sable nodded. Her hands found the bio-tissue. The communication layer opened. The ship's filters engaged.
"Corvin. Maximum speed. All five pillars at full output."
"Full output shortens my sustainment window," Corvin said from the sub-chamber. "At maximum, the drive can run for approximately three hours before I need to throttle back."
"Three hours is what we need. Push it."
The five pillars surged. Power output climbed from seventy-eight percent to eighty-one. Eighty-three. The Expanse's ambient dimensional energy feeding into the drive, the inner Expanse's compressed environment providing more fuel than the outer regions, the ship accelerating as the pillar output increased.
"Malik. Weapons hot. Lance batteries on standby. If anything comes out of that tear in the seal before we get there, I want the option to shoot it."
"Batteries calibrated and armed, Captain. Stars witness whatever comes through."
Kira pressed her left palm into the Throne. The passive sense opened. The inner Expanse's dimensional currents flowing through her awareness, the path ahead visible as pressure and rhythm and the half-heard music of spacetime in motion. No Aria-7 navigation support. No sensor analysis. Just her modified perception and the ship's instincts and the hope that the Hollow King's tuning had made her good enough to fly blind through the most dangerous region of space in the known galaxy.
"All stations," she said. "We're going in. Three hours to the seal. Everything happens in parallel. Sable talks to the entity. Voss processes the data. The Emperor's engineers modify the Platform. Niko recovers. And I get us there alive."
The ship flew. The seal cracked. The Platform poured energy into the void. And somewhere behind them, Kaine's damaged interceptor followed the trail they'd carved through the Expanse, slower but relentless, the hunter who had promised he would be there when they stopped.
Six hours. Maybe less.
The crew of a Progenitor warship flew toward the broken center of the galaxy with a half-calibrated weapon and four-fifths of the pilots they needed and a plan that wasn't a plan anymore but a list of things that all had to work simultaneously or none of them would work at all.
Sable's hands pressed into the wall. The communication layer reached across the void toward the seal. The Hollow King was waiting. Its condition was waiting. And the answer to whether any of them survived the next six hours was locked behind a conversation with an entity that was older than human civilization and wanted to die but wanted something else first.
"Show me," Sable sent through the filters. "Show me what you want."
The ship's bio-tissue flared gold. The seal cracked wider.
Something answered.
