Ter 3 hit one hundred percent at four in the afternoon on Day Four.

Michael was on the third floor helping Shin and Rei with the barrier placements when the notification came and he stopped and looked at it in his vision and felt the particular weight of it settling.

[Base Tier 3 — Settlement: Complete.]

[Tier 4 unlocked — Fortress.]

[New blueprints available: Advanced Turret System, Underground Expansion, Blast Walls, Satellite Outpost, Mobile Base Foundation.]

[Territory Pulse upgraded — Range extended to fourteen blocks.]

Fourteen blocks.

He pushed the pulse immediately to the new range and the picture it gave him expanded in every direction and he stood in the third floor corridor and read what he was seeing and his jaw tightened slightly.

The southeast signature was five blocks away now.

It had moved again while he was working, another block closer, and the slow deliberate pace of it was exactly the same as every other movement it had made, unhurried, one block at a time, like it was making a point about patience rather than actually being patient.

But the extended range gave him something new.

Behind the main signature, further out, he could feel the shape of what was coming with the full fourteen block sweep and it was bigger than eleven. Significantly bigger. The signatures back there were dense enough that individual counting was difficult but he could feel the mass of them spread across the southeastern blocks and the number he arrived at was somewhere between forty and sixty and none of them were moving yet, just sitting in the same park area Cole and Yuna had observed, waiting for whatever signal they were waiting for.

He stood in the third floor corridor with the barrier materials stacked around him and Shin and Rei looking at him with the particular attention of people who had learned to read his stillness.

"How far," Shin said.

He looked at her. She looked back and her eyes were steady.

"Five blocks," he said. "The main one."

She nodded. "And the others."

"Further back," he said. "But more than we thought."

Rei was looking at him with her dark eyes calm and focused and she had a length of pipe in her hands from the barrier materials and she was holding it the way she’d been holding things since she arrived, like she’d decided somewhere along the way that she was going to be ready for whatever came and was holding herself to that decision.

"How long," Rei said.

"Tonight maybe," he said. "Tomorrow at the latest."

The corridor was quiet for a moment.

"Then let’s finish the barriers," Shin said and picked up her materials and went back to work and Rei looked at Michael for one more second and then followed her and Michael stood in the corridor for a moment longer and then pulled up his comm system, a Tier 3 unlock he’d built into the base infrastructure that let him send a pulse alert to everyone in the building simultaneously, and activated it.

One pulse. The signal they’d agreed meant everyone to the sixth floor common space immediately.

Then he went upstairs.

---

They were all there by the time he arrived.

His five, Cole’s group, Damon’s four, Gareth’s remaining men, Anya, Rei who had come up with Shin, Yuna who had been in the training room and arrived with her hair loose and her hands still wrapped from the session. Nineteen people in the living room and hallway of the sixth floor apartment and the spaces around it, all of them looking at him with the focused attention of people who had received a one pulse signal and understood what it meant.

Gareth was at the back of the group with his arms crossed and his eyes on Michael and the easy look was not in place today, had not been in place since the Cole and Yuna report three days ago, and the face underneath it was sharp and focused and paying close attention.

Cole was near the front and he looked at Michael’s face and read it and his jaw set slightly in the way it set when he was processing threat information and updating his response plan.

Michael looked at the room.

"Tier 3 is done," he said. "The pulse range extended to fourteen blocks when it completed. I ran a full sweep." He paused. "The southeast group has moved to five blocks out. There are more of them than the initial count suggested. Somewhere between forty and sixty total."

The room processed that.

"Forty to sixty Aberrants," Cole said. Not loud, just making sure the number was stated clearly.

"Yes," Michael said.

"Timeline," Cole said.

"Tonight or tomorrow," Michael said. "They’ve been moving one block at a time and the pace has been accelerating. Five blocks is close enough that the next move puts them at the wall."

The room was quiet.

Gareth uncrossed his arms. "What’s the plan," he said. It was the first time Gareth had asked Michael that question in a way that didn’t have anything underneath it and Michael noted that and moved on.

"Turrets cover the exterior," he said. "Automated on primary, Maya on manual override from the lobby panel. Everyone else is in two teams. Cole takes the east and south wall sections, Gareth takes north and west. Sera runs the interior response, anything that gets through the wall goes through her team first. Dr. Kang and Anya stay on the sixth floor, Dr. Kang runs medical and Anya manages the supply and communication relay." He looked at Shin and Rei. "Third floor barriers are your responsibility. If something gets to three you slow it and you signal and you do not engage alone."

Shin nodded.

Rei nodded.

"Yuna," he said.

She looked at him.

"You’re with Sera," he said. "Interior response needs your range."

She nodded once and her jaw was set and her eyes were clear and she looked like someone who had been thinking about this since the watchtower report and had already made her peace with it.

"What about you," Sera said. She was looking at him from the kitchen doorway with her arms at her sides and her axe in her hand and her eyes direct.

"Everywhere," he said. "Pulse tracking, system management, response coordination, wherever the line needs holding." He looked at her. "And with you when it gets to that."

She held his gaze for a second and then nodded.

"Questions," he said.

Damon raised a hand halfway. "The Aberrants. Can the turrets handle them."

"They can handle Brutes," Michael said. "Aberrants are faster but the turret tracking system accounts for Stalker speed. They’ll handle them." He paused. "The question is how many at once."

"Forty to sixty," Damon said.

"The wall creates a choke point," Michael said. "They can’t all hit at once. The turrets prioritize by proximity and the corner overlap means there’s no blind spot in the exterior coverage." He looked at Damon. "The wall does a lot of the work. Our job is to handle whatever gets through."

Damon nodded and put his hand down.

Nobody else had questions.

"Get some rest," Michael said. "Eat something real. Check your weapons and your positions and then rest. We don’t know if it’s tonight or tomorrow and being exhausted when it comes is not an option." He looked at the room one more time. "This building has held for thirty five days. It holds tonight too."

He said it with the same certainty he’d used with Yuna at the gate and the room received it the same way, the body believing it before the brain finished processing it, and people started moving with the focused calm of a group that had a plan and trusted the plan.

Cole stopped beside him on the way out. "The Tier 4 unlocks," he said quietly.

"Blast walls," Michael said. "First thing on the list."

Cole nodded. "And the advanced turrets."

"Right after," Michael said.

Cole looked at him. "You’re going to build during the contact event."

"If there’s time between engagements yes," Michael said. "The blast walls add a secondary perimeter inside the main wall. If the turrets are holding the exterior I can be building the interior layer."

Cole looked at him for a long moment. "You’re going to be building while we’re fighting," he said.

"I’m going to be doing both," Michael said.

Cole looked at him and something in his face settled into the expression he wore when he had assessed something and arrived at an answer he was satisfied with. "Alright," he said and went to brief his group.

The evening was quiet in a way that had weight to it.

People ate and checked weapons and moved through the building with the particular focused calm of those who had done what they could and were now waiting for the thing they’d done it for. The training room was empty for the first time in days. The greenhouse sat dark on the roof. The turrets on the wall corners sat in automated standby mode, tracking, waiting, patient in a completely different way to the thing five blocks southeast.

Michael sat in his spot on the floor and ate what Yuna had made, she’d been in the kitchen for an hour in the late afternoon and the result was the most real food the building had produced since before the world ended, and he ate and looked at the pulse and thought about everything and nothing simultaneously the way the mind did when it had processed all the available information and was waiting for something to happen.

Sera came and sat beside him.

Not across from him. Beside him, with her back against the same cabinet and her axe across her knees and her shoulder three inches from his and she didn’t say anything and he didn’t say anything and they sat like that in the quiet of the apartment with the evening settling around them.

After a while she said "the Skill Echo."

He looked at her.

"I felt it when you activated it," she said. "Like something being copied." She looked at him sideways. "Which skill."

He thought about whether to say it and decided that tonight was not the night for not saying things.

"Movement reading," he said. "Reading an opponent’s body before they commit."

She was quiet for a moment. "That takes years to develop properly," she said.

"The system compressed it," he said. "It’s there. I don’t know how well yet."

She looked at her axe. "You activated it because of tonight."

"Yes," he said.

She was quiet again and the apartment was quiet around them and outside the city was dark and the wall stood on four sides and the turrets tracked their ninety degree arcs and five blocks southeast something that could think was one block away from being at the wall and the night was just beginning.

"Michael," Sera said.

"Yeah," he said.

She was looking at her axe and her jaw was set and her shoulder was still three inches from his and she said "don’t do anything stupid out there" in the flat direct tone she used for things that mattered.

He looked at her profile in the dim light of the apartment and thought about thirty five days and a hallway and a woman with a fire extinguisher who hadn’t trusted him and had decided to anyway and everything that had built up since then without either of them making a production of it.

"Same to you," he said.

She looked at him and held his gaze for a moment that was longer than the ones before it and then she looked back at her axe and they sat in the quiet together until the pulse changed.

--- 𝕗𝚛𝚎𝚎𝐰𝗲𝗯𝗻𝚘𝚟𝚎𝗹.𝕔𝐨𝕞

It changed at eleven forty seven.

Michael felt it before he saw it, the particular quality of the sweep shifting from ambient background to something active and directed, and he looked at the southeast and the signature was moving.

Not one block at a time.

All of them. Moving together, fast, the whole mass of signatures accelerating from stationary to a pace that confirmed what Dr. Kang had said about speed and confirmed what Cole had said about coordination and confirmed what Yuna had said about the calm behind the eyes of the one that had looked at their window.

They weren’t testing anymore.

They’d decided.

He was on his feet before the thought finished forming and Sera was up beside him with the axe in her hand and her eyes on his face.

"Now," he said.

She was already moving.

He activated the building wide alert, three pulses this time, the signal they’d agreed meant contact imminent, and pulled up the turret control system and switched from standby to active and watched the four corner turrets come online in the Blueprint Interface overlay, their targeting systems spinning up and the proximity tracking engaging across the full exterior perimeter.

Then he pulled up the Tier 4 build queue and selected the blast walls and confirmed the materials and felt them begin to assemble in the courtyard between the outer wall and the building entrance while the pulse showed him forty seven individual signatures moving through the eastern streets toward his building at a speed that made his chest tight in a specific way that was not fear exactly but was something adjacent to it that made everything sharper.

He looked at the building around him. At the wall and the turrets and the barriers and the clinic and the greenhouse and the training room and nineteen people moving to their positions in the dark with the focused calm of people who had been given something worth protecting and had decided to protect it.

Then he went to where he needed to be.
