Edge of Endurance

The constant, sterile buzz of ONI's medical bay grated on his senses. The bright lights overhead flickered, throwing harsh shadows across the walls. He lay on the examination table, half-stripped of his armor, his chest and side wrapped in temporary medical seals that hissed every few seconds, administering localized painkillers and skin repair agents. The sound reminded him of Harvest—of the medics patching up the few who survived each Covenant onslaught. But he wasn't seventeen anymore, and those wounds ran deeper than flesh.

The room was empty save for him, the low hum of machines his only companion. Alyssa had vanished the moment they landed, off to file her reports or get some much-needed sleep. The base felt like a ghost town. Even the doctors seemed to operate in cold, mechanical rhythms, slipping in and out without a word.

He was used to that. No one asked how a mercenary felt. No one cared what his pain was, beyond patching it up so he could be thrown back into the meat grinder of war.

His gaze shifted to the dull reflection in the metal tray beside him. For a second, he almost didn't recognize the man staring back. The face looked the same—scarred, hollow, eyes that had seen too much—but there was something else now. A sense of... disconnection, as if his body was becoming just another tool. Just another part of the machine.

The system was still there. It hovered in the corner of his vision, patient, waiting. It hadn't blinked away, no matter how many times he closed his eyes. The words were like ghosts, intangible and yet very real.

[Health: 40%. Energy: 15%.]

[Quest Complete: Survive.]

He frowned. It wasn't the way it should have been. There was something unnatural about it. Something invasive. He wanted to ignore it, dismiss it as a glitch, but his instincts told him this was something far bigger than an anomaly in his HUD.

[Level 1: Survivor.]

"What are you?" he muttered under his breath, narrowing his eyes at the persistent display.

A sharp knock on the door interrupted his thoughts. He tensed, turning his head toward the sound. His hand instinctively moved toward his pistol—a reflex he hadn't shaken since Harvest.

The door slid open, revealing Alyssa. She stepped inside without waiting for an invitation, her eyes scanning the room before settling on him. She had changed out of her flight suit into standard UNSC fatigues, though her expression was the same unreadable mask she always wore.

"You look like hell," she said, repeating her words from earlier, though this time there was an edge of concern buried beneath the sarcasm.

"You've got a gift for understatement," he replied dryly, pushing himself to a sitting position. The movement sent a sharp stab of pain through his ribs, but he grit his teeth and ignored it.

Alyssa leaned against the wall, crossing her arms over her chest. "You really should let the doctors finish with you. That armor took a serious hit."

"They've done enough," he muttered, waving off her concern. "I've had worse."

She stared at him for a moment, then sighed. "Yeah, well, it's not just the armor I'm worried about. That last hit you took… you should be dead."

He stiffened at her words, his mind flashing back to the moment before the explosion—the feel of the plasma grenade's heat, the weight of his body being thrown through the air. He remembered the pain, the shock, and then... the system.

"I'm not dead," he said simply, his voice cold.

Alyssa's gaze sharpened. "That's what I don't understand. I saw you go down. No one gets up from that kind of blast, not without some serious medevac. Yet here you are, patched up like it was just a scratch."

For a brief moment, he considered telling her about the system. About the strange numbers and words that seemed to pull him back from the brink. But something held him back. It wasn't just that it sounded crazy—it was that he didn't fully trust her. Not yet.

Instead, he deflected. "You want me to apologize for surviving?"

Her eyes flickered with frustration, but she didn't press the issue. "No. I just want to know how you did it."

He didn't have an answer for her. The truth was, he didn't know how he had survived. The system had done something—he felt it in his bones. But the how and why remained a mystery. And until he understood it, he wasn't about to share it with anyone.

Especially not ONI.

"Luck," he said finally, his voice flat. "Maybe I've still got some left."

Alyssa didn't seem convinced, but she didn't push. Instead, she walked closer, her gaze softening slightly. "Look, I know you're used to going solo on these kinds of ops. But this isn't just another mission. Whatever ONI's planning, it's bigger than either of us. If we're going to survive, we need to stick together."

There it was again. That word. Survive. It felt like a command now, something that wasn't just a passive action but an active struggle. He wasn't just staying alive; he was being forced to endure, to push past his limits.

A part of him wanted to scoff at her suggestion, to remind her that ONI didn't care about them as individuals. But the other part—the part that had felt the weight of her body pulling him to safety, covering his retreat—knew she was right.

"I don't trust them," he said quietly, the words surprising even himself. He hadn't intended to be that honest.

Alyssa nodded slowly, her eyes studying him. "Neither do I. But that doesn't mean we can't trust each other."

For the first time since Harvest, he felt a flicker of something. It wasn't trust—not fully—but it was close. An acknowledgment that maybe, just maybe, he didn't have to walk this path alone. Not yet, anyway.

Before he could respond, the door slid open again, and a young ONI operative stepped inside, his posture rigid and formal. He was fresh-faced, probably no older than twenty-five, with a clean-cut look that screamed inexperience.

"Commander Tate is ready for your debriefing," the operative said, his voice lacking any warmth or emotion. He glanced at Alyssa and the mercenary as if they were mere assets, not people.

"Tell Tate we'll be there in five," Alyssa replied curtly. The operative nodded stiffly and exited the room, leaving them in silence once again.

The mercenary stood slowly, testing the limits of his body. The pain was still there, but it was manageable now. The system's numbers blinked again as if mocking his endurance.

[Health: 55%. Energy: 20%.]

He wasn't sure what those numbers meant, not exactly. But he had a feeling they weren't going to go away anytime soon.

Alyssa watched him carefully, her arms still crossed. "You ready for this?"

He nodded. "As ready as I'll ever be."

They left the med bay together, walking in silence through the sterile corridors of the ONI base. The further they went, the more the walls seemed to close in around him, the weight of the war pressing down like a physical force. Every mission was the same—another piece of the endless, grinding machine. Another step toward a war that never seemed to end.

But now, with the system in his head and Alyssa by his side, things felt... different. Uncertain. Dangerous in a way he couldn't quite define.

As they approached the debriefing room, he glanced at her out of the corner of his eye. She met his gaze, her expression unreadable but steady. There was something about her that unsettled him—not because he didn't trust her, but because he might start to.

And in this galaxy, trust could get you killed.

The door slid open, and they stepped inside. Commander Tate was already waiting, his eyes sharp and calculating. He glanced at the two of them and then at the data chip sitting on the table in front of him.

"Well," Tate said, his voice a cold drawl. "Let's see what we've got."
