Two days after Cora's arrival, the Outpost had settled into the particular rhythm that followed any significant disruption—a kind of recalibration, not quite tension and not quite peace, the squad finding the new shape of things by degrees. Cora had taken up residence in the east wing without complaint and spent her first morning running drills in the training corridor at a time Arthur privately estimated was earlier than medically advisable. He had not commented on it. The willingness to overwork was something he recognized, and the cure for it was belonging, not instruction.
He was in the common room with a mug of something Anis had brewed from the Outpost's remaining stock of coffee beans when the outer door opened and Delta came in moving at a pace that immediately told him this was not a routine return.
She was in field kit—the lightweight scout configuration she and Signal used on longer-range sweeps, dust still on her boots and a smear of dried blood on her left forearm that was not fresh enough to worry about. Signal was a half-step behind her with the same worn-in look, and behind Signal came a stranger.
The stranger was short, Elysion markings integrated into the right shoulder of her outfit in the pale blue-white of that manufacturer's aesthetic. Whire hair, pulled back with the casual efficiency of someone who didn't care much about appearance in the field but had enough pride that it didn't get in the way. She was carrying a shotgun in both hands at a port-arms carry that said *comfortable* rather than *ready*, the way a person carried a tool they used every day, and she was looking at the Outpost interior with the expression of someone who had been told what to expect and had not believed it until now.
Delta looked at Arthur, and the expression she was wearing was specific: the expression of someone who had done something they knew would require a conversation, and had done it anyway because they had judged it necessary.
"Sit down," Arthur said, setting his mug on the table.
"I'd rather stand for this part."
"Delta."
She sat.
The story came out in the direct manner she always used when she'd had time to organize it—she and Signal had been running the standard long-range sweep east of the perimeter, the kind that mapped degradation patterns in the surface approaches to Sector Eighteen, when Signal had picked up a signal trace moving through the lower-level access points three kilometers out. Moving wrong for a Rapture, too deliberate and too quiet. They'd tracked it to an Elysion Nikke separated from her squad during the ambush that had precipitated the Sector Eighteen operation. She'd been navigating alone for nineteen hours and was doing it well, which was the first thing Delta had marked down as relevant.
The Nikke—Neon, the stranger confirmed from across the room, not sitting, still holding the shotgun—had been trying to find her squad's last known position. In the process, she had gone down into a fracture in the lower substrate, following a vibration signature that had suggested structural venting rather than Rapture biology, and had found herself somewhere else entirely.
Arthur said, "A Lost Sector."
Delta held his gaze. "Intact infrastructure. Pre-war, sealed. She was inside for six hours before she found the exit, and she says she catalogued what she could."
There was a particular quality to silence that filled spaces when something important was being understood. Arthur sat with it for a moment, and then he turned and looked at Neon directly for the first time.
She met his eyes without flinching, which he noted. The white hair had more dust in it than he'd initially registered, and there were stress fracture marks along the left pauldron consistent with something heavy landing badly on that shoulder. She looked like someone who had been through a rough several days and had opinions about it.
"What did you catalogue?" Arthur asked.
"Storage levels on sub-four," Neon said. Her voice was direct, no performance to it. "Preserved. The atmosphere seal held somewhere. There are crates I didn't open—markings I didn't recognize, some I did. Medical equipment. Heavy weapons storage that I spent probably more time than I should have looking at." A brief pause. "And a room on sub-two that had containment pedestals. The kind with active field emitters. The kind that would have been used for sensitive tech."
Arthur was quiet for a moment. Then: "How many pedestals?"
"Three. One looked damaged. The other two—" She stopped, then continued with the careful precision of someone recalling exactly: "The other one had field-emission residue consistent with an extended storage period. Whatever was in them is gone. But one remained. Cubical, inside the field matrix."
One Harmony Cube-shaped possibility.
Arthur looked at Delta.
Delta said, "I know."
"You made her a promise on my behalf," Arthur said. The tone was even, which was not the same as calm.
"I did." Delta replied. "I offered her a position in Monarks without authorization, in exchange for information about a discovery that was hers to report to Elysion."
"Ingrid's teams would have been through that sector in forty-eight hours," Delta said, with the composure of someone who had already argued this with herself and arrived at the same conclusion twice. "Everything in it would have been catalogued, pulled, and absorbed into Elysion's inventory before we knew it existed. You know what's in that pedestal. You know what it would mean for Lyra. For Anne."
Arthur knew. That was the problem with Delta—she knew him well enough to find the exact argument that made being annoyed difficult to sustain.
He let out a breath through his nose, turned the mug in his new hand, felt the pressure feedback of the ceramic rim against the prosthetic fingers, the sensation still carrying that slight richness the technician had promised would normalize.
"Fine," he said.
Neon, who had been watching this exchange with the attentiveness of someone sitting an examination, said, "I'm not a charity placement."
"No," Arthur agreed. "You're not." He looked at her properly now, the way he looked at new members—not as an assessment of threat or value, but as an attempt to understand what the person actually was. "Delta vouched for you. Delta's the best scout I've known. That means something."
"Signal vouched for me too," Neon said.
Signal, who had been quiet in the doorway, raised two fingers in brief confirmation and then went back to examining the architecture of the common room ceiling.
"She's good," Signal said. "Fast, good situational awareness, and her breach-and-clear on the access tunnels—" A pause. "She went first. Every time."
Arthur looked at the shotgun. "You always carry it like that?"
Neon glanced down at it with an expression that was almost surprised by the question. "It's a shotgun," she said, as if this answered everything. Then: "I have two more in storage back at Elysion depot. I was thinking about requisitioning a third."
Anis appeared in the corridor doorway, coffee in hand, caught the last sentence, and said, "I like her," before disappearing again.
Arthur stood. His ribs registered the movement with the dull, sullen protest of the not-quite-healed, and he let it pass without acknowledgment. "We're going to the Lost Sector today. I want to be in and out before Ingrid's network picks up any anomalous survey data from that grid." He looked at Neon. "You lead us in. Signal and Delta on point and flank." Then he turned toward the corridor that led to Bravo's quarters. "I'm taking the second team."
Twenty minutes later, Bravo was assembled in the equipment bay.
Miranda was already in combat configuration, the compact SMG checked and stowed, her expression the particular focused neutrality she carried before operations. Flower was beside her talking to Ocean in the rapid shorthand they used when they thought no one was paying attention. Ocean had her rocket launcher broken and checked on the bench in front of her, which she was reassembling with the calm, methodical attention she brought to everything she considered important. V was seated on the edge of the equipment locker, katana across her knees, the sniper rifle in its case propped against her left leg, and she was watching Cora.
Cora was standing near the wall with her sidearm holstered and the Cerberus-spec shotgun across her back, and she was doing the same cataloguing Arthur had watched her do in the transport from HQ—taking the shape of the team and filing it carefully.
Voltia stood slightly apart, assault rifle already loaded, fingers moving in the absent electrical tests she ran when she was thinking about something she didn't want to voice.
"New sector," Arthur said. "Elysion hasn't documented it. I want that to remain true for as long as possible." He met Miranda's eyes, then moved down the line. "We're going in as a survey unit, not a combat element, but we'll move like a combat element because the floor plan is unknown and the sector was sealed for a significant period. Treat every room as potentially hostile until it isn't." He looked at Cora last. "First field operation with this team. Tell me now if there's anything I need to know about the biotic integration in confined spaces."
"Range is consistent within twelve meters," Cora said. "In a sealed corridor it can bounce. I'll call it before I use it."
"Good."
Neon had come to stand at the edge of the group during this, the shotgun now resting against her shoulder. She was watching Arthur with an expression he couldn't entirely categorize—not skepticism, not deference, but something in between that was working itself toward a conclusion.
"You're really the one who killed the Gatekeeper," she said.
"We killed the Gatekeeper," Arthur said. "The distinction matters."
Neon considered that. Then she settled the shotgun against her other shoulder and said, "Okay." As if she had made a decision and intended to stick with it.
The transport rolled out of the Outpost bay into the approach tunnels ten minutes later. Delta sat in the forward section with a map that was mostly guesswork past the two-kilometer mark, Signal marking observed terrain features in the margin with the careful, habitual notation of someone who had been doing this long enough that it was automatic. Neon sat across from Arthur with the shotgun between her knees and said, without preamble, "The heavy weapons storage on sub-four. I want to be direct with you."
"Go ahead."
"I didn't leave it the way I found it," she said. "I may have moved some things."
Arthur looked at her. "How many things."
"Five. Six if you count the prototype." A pause. "I put them back. Mostly."
From somewhere behind them, V said, quietly and to no one in particular: "Yes. I think I understand why Anis liked her."
