The frost came early that year, a full week before anyone expected it, silvering the training yard overnight and turning the Abyssal Frontier's already grey mornings into something almost beautiful, in the brief, brittle way frost made everything look breakable. Vane stood at the mouth of his tent watching his own breath fog in the cold and thought, not without some grim humor, that the timing was almost too on the nose. The Chancellery's deadline had arrived with the season.

*"You still haven't finished the report,"* Eric said. It wasn't a question.

"I've finished most of it. I keep getting stuck on the same paragraph."

*"Show me."*

Vane huffed, low, and unfolded the half-written pages from where he'd tucked them inside his coat. *The weapon's origin remains unclear,* he'd written, and then crossed out, and then rewritten three different ways, none of which had satisfied him. He was a soldier, not a diplomat; he could draft a battle plan in the time it took most clerks to sharpen a quill, but lying convincingly to men who made a career out of catching lies was a different discipline entirely, and one he had never bothered to master because he had never before had anything worth hiding this carefully.

*"You're overcomplicating it,"* Eric said. *"You don't need eloquence. You need consistency. Tell them the artifact manifested during a life-threatening magical crisis, that its properties are still being assessed, that early indications suggest forcible removal would likely kill the host. Cite your own condition as the reason further study requires time and stability, not urgency. Bureaucrats respect caution when it's dressed up as prudence instead of evasion."*

"You've done this before."

*"I've written more insurance appeals and ethics board justifications than I care to remember. The language is different. The principle is the same — give them a reason to leave you alone that sounds like responsibility rather than defiance."*

"You make it sound almost easy."

*"It isn't easy. It's a skill, like any other. You've spent twenty-eight years learning to read a battlefield in half a heartbeat. I spent twenty learning to read exactly how much truth a frightened family could survive hearing all at once. Different terrain. Same instinct — give people only what they can actually use, and protect them from the rest until they're strong enough to carry it."*

"You talk about your old work like you miss it."

*"I do. Some days more than others. It's strange — I spent the last several years of that life resenting how much of myself it consumed, and now that it's gone I find myself missing the exact thing I used to complain about. I suppose that's its own kind of foolishness."*

"Not foolishness," Vane said. "Just grief wearing a different coat."

*"You're quoting me back to myself."*

"You said it first. I'm allowed to have learned something from you by now."

Vane picked up the quill again, and this time the words came easier, guided by something that was, he was coming to realize, an entirely different kind of expertise than swordsmanship — one just as sharp, in its own quiet way, and considerably better suited to surviving an Empire that preferred paperwork to open war.

They finished the report by midmorning, and Vane sent it off with the same courier who'd delivered the original demand, along with instructions to make the ride back to the capital look neither hurried nor reluctant — an art Vane had learned young, in a court where every gesture was read as a message whether or not one was intended.

With the immediate crisis handled, or at least deferred, Vane found himself with a rare stretch of unclaimed hours, and no particular appetite for spending them on the reports and requisitions that usually filled every spare moment of his day. He walked instead to the edge of the camp, where the frost gave way to the black rock that marked the true border of the Abyss, and sat on a boulder that had, over eight years, become something like a private habit — the one place on the frontier where he allowed himself to simply exist without an audience.

*"You come here a lot,"* Eric observed. *"I've noticed the pattern in your heart rate. It always settles here."*

"It's quiet."

*"It's isolated. There's a difference, though I understand why you might prefer not to examine it too closely."*

Vane huffed something that wasn't quite a laugh, watching the wind move over the black stone in slow, restless waves. "You have a talent for finding the thing I'd rather not examine."

*"I told you. Occupational hazard."* A pause, and then, more carefully: *"Can I ask you something? Not medically. Just — as whatever we are to each other now."*

"Go on."

*"Your mother. You mentioned her once, in passing. You said no one had asked about your heart being all right since she died. I haven't asked what happened to her, because it felt like the kind of thing you'd tell me when you were ready, not when I pushed. But if you want to tell me now, I'd like to hear it."*

Vane was quiet for a long moment, long enough that a hawk crossed the grey sky twice before he answered. "She was a healer. Not a battle-mage — a real one, the kind who worked in the poor districts of the capital because no one else would. She died of an illness she'd have caught early in anyone else's patient and missed in her own, because she never once put herself first in her life. I was twelve. My father had already died on this same frontier two years before that, so after her there was no one left who wanted anything from me except what use I could be to the crown."

*"I'm sorry,"* Eric said, quiet, and there was nothing clinical in it at all.

"It was a long time ago."

*"That's not the same as it not mattering anymore."*

Vane looked out at the black rock, at the thin ribbon of frost still clinging to its edges in the places the sun hadn't yet reached. "She would have liked you," he said, finally, surprising himself with how easily it came out. "She always said healers and soldiers wanted the same thing, in the end. Just different ways of trying to keep people alive."

*"I think I would have liked her too,"* Eric said, softer than Vane had heard him yet, and for a while neither of them said anything else, content to let the silence hold the shape of a woman neither of them could bring back, in the only way either of them currently had available to honor her.

"Your turn," Vane said, eventually, low. "You asked about my mother. I want to know about the family you left behind. If there's anyone waiting for a doctor who isn't coming home."

Eric was quiet long enough that Vane thought, for a moment, he'd overstepped. *"No one waiting, exactly,"* he said finally. *"My parents died when I was young enough that I don't remember much beyond hospital corridors and other people's kindness. I built a life out of work instead — colleagues, a few friends I saw twice a year if I was lucky, patients who mattered to me more than I ever let myself admit while they were under my care. No one who'll be standing at a grave wondering where I went. Which I used to think made my death simpler, in a strange way. Fewer people to grieve."*

"And now?"

*"Now I think it just means fewer people who'll ever know I existed at all, unless you decide to tell them."* A pause, quieter. *"I'm not sure how I feel about that yet."*

"I'll remember you," Vane said, simply, without ceremony, the way he said things he meant absolutely and had no intention of repeating twice. "However this ends. Whatever you decide you are. I'll remember exactly what you did for me, and exactly who you were while you did it."

Eric didn't answer that immediately, and when he finally did, his voice carried a rough, unguarded warmth Vane hadn't heard from him before. *"Thank you,"* he said. *"That matters more than you probably realize."*

---

The scouting party returned at dusk with worse news than either of them had expected: a fresh rift had opened two days' ride to the north, smaller than the one that fed the Abyssal Frontier itself, but active, and bleeding Rift-Spawn into a stretch of borderland that had no standing garrison to meet them. Vane called his officers together within the hour, mapped a response with the efficient, joyless speed of a man who had done this more times than he could count, and found himself, an hour later, riding out at the head of two companies with Eric quiet and attentive in his chest.

*"You didn't have to lead this one personally,"* Eric said, once they were clear of camp, hooves striking a steady rhythm against the frost-hardened ground.

"A new rift means unpredictable terrain and unpredictable numbers. I won't send men into that without having walked it myself first."

*"That's not company policy. That's you refusing to let anyone else carry a risk you could carry instead."*

"Call it what you like. It's kept most of them alive this long."

*"It's also going to be what kills you eventually, if you don't learn there's a difference between leading and martyring yourself by inches."* Eric's voice sharpened, not with anger exactly, but with something close to it — the particular frustration of watching someone repeat a mistake you'd already diagnosed. *"You told me your mother never put herself first. You're doing the same thing, just with a sword instead of a healer's satchel."*

Vane's jaw tightened, but he didn't argue, mostly because he suspected, uncomfortably, that Eric was right, and there was no version of denying it that would survive contact with his own conscience.

The rift, when they reached it, was a raw wound in the world — a tear of unnatural light bleeding at the edges of a shallow valley, disgorging Rift-Spawn in irregular pulses that made timing any coordinated attack difficult. Vane fought at the center of the formation as he always did, drawing the worst of the attention toward himself so his soldiers could work the flanks, and Eric, true to form, kept up a running commentary of vitals and warnings throughout, sharper and more insistent than he'd ever been in a lower-stakes skirmish.

*"Heart rate one-forty. You're fine. Watch your left, there's a gap in your guard when you overextend that arm."*

"Noted." Vane pivoted, caught a Rift-Spawn's charge on his shield, and drove his crystal blade through its throat in the same motion. Around him, the valley rang with the clash of steel and the shriek of dying things, and for a long, brutal hour there was no room in his mind for anything except the fight in front of him.

It was near the end, when the rift's pulse of monsters was finally thinning, that a Rift-Spawn larger than the rest — some twisted alpha of the swarm, easily twice the height of the others — broke from the treeline and drove straight for a knot of young soldiers who had, in the chaos, lost their formation.

Vane didn't think. He moved, cutting across the field at a dead sprint, putting himself between the creature and the boys before his own officers had fully registered the threat.

*"Heart rate one-ninety-five,"* Eric said, tight and urgent now, all humor gone from his voice. *"Vane, that's too high, you need to—"*

"Not now."

The alpha's claw caught his shoulder as he threw himself into its charge, tearing through leather and skin both, and the pain that followed was distant, secondary, the kind of thing Vane had trained himself years ago to set aside until a fight was over. He drove the crystal blade up and through the creature's exposed underside with the last of his momentum, and it went down in a spray of black blood, and the boys behind him scattered clear, and for one suspended moment the whole field seemed to hold its breath.

Then the adrenaline receded, all at once, the way it always eventually did, and the pain in his shoulder arrived in full, and his vision swam.

*"Sit down,"* Eric said, no longer sharp, just urgent, almost frightened in a way Vane had not yet heard from him. *"Now. Please."*

Vane sat, hard, in the frost-damp grass, and let Eric work — that same strange, cool sensation spreading through the wound, easing the worst of the bleeding, dulling the pain to something bearable. Around him, his soldiers were already regrouping, the alpha's death sending the remaining Rift-Spawn scattering back through the thinning rift, and somewhere distant Marek was shouting orders to secure the valley, and none of it mattered quite as much, in that moment, as the quiet, careful attention of the presence in his chest.

*"That was reckless,"* Eric said, once the worst of the wound had been addressed. *"Even by your standards."*

"They were seventeen. Both of them. I wasn't going to watch that happen from a distance."

*"I know why you did it. I'm not asking you not to protect people. I'm asking you to stop treating your own survival as negotiable every single time it's your body on the scale."* A pause, and then, quieter: *"I felt that claw hit you the same instant you did. Do you understand what that means? If it had been an inch to the left, if it had caught your throat instead of your shoulder — I would have felt that too. All of it. And there's no coming back from that, for either of us."*

Vane heard, underneath the clinical framing, something that sounded very much like fear — not the practiced, professional concern Eric usually wore like a second skin, but something rawer, closer to the surface, the kind of fear that came from a person who had already, once, lost the ability to protect what mattered to them.

Vane went still, the reality of it settling over him with a weight the pain hadn't quite managed. He had grown so used to Eric as a comfort, a presence, a voice that made the loneliest parts of his life feel less loud, that he had not fully reckoned with the reverse of that arrangement — that every risk he took alone, he now took for two.

"I hadn't thought of it that way," he admitted, low.

*"I know. That's exactly the problem."*

Vane sat with the shape of that for a long moment, watching a thin trail of smoke rise from a soldier's cookfire further down the valley, and found, for the first time in eight years of careless, deliberate risk-taking, that the calculation had changed. It was no longer only his own life on the scale when he threw himself into a fight without hesitation. He would have to learn, he realized, to weigh that properly — not to stop protecting the people under his command, but to stop treating his own survival as something infinitely renewable, a debt he could keep drawing against without ever expecting the ledger to close.

---

They rode back to camp in the last grey light of evening, the wounded shoulder bound and aching, the valley behind them quieter than it had any right to be after so much violence. Vane said little on the ride, turning Eric's words over with the same careful attention he gave a battle plan, and it was only once they were back within the relative safety of his own tent, the wound properly cleaned and dressed, that he spoke again.

"You're afraid," he said, quietly. "Of losing me. Not just professionally. Not just as a patient."

There was a long pause. *"Yes,"* Eric said finally, and the admission seemed to cost him something significant, some careful distance he'd been maintaining since the moment he'd woken in Vane's chest. *"I am. I didn't expect to be, this quickly. I've spent my whole life keeping a professional distance from patients precisely so I wouldn't have to feel this, and it turns out that distance isn't available to me anymore. I'm inside you. There's nowhere left to retreat to."*

"Is that so terrible?"

*"It's terrifying,"* Eric said, with a rawness Vane hadn't heard from him before. *"Because I don't know how to keep you safe and also keep myself from caring what happens to you, and I've never once had to do both of those things at the same time before."*

Vane sat with that for a long moment, his good hand coming up, as it always did now, to rest over his heart — over both their heartbeats, he understood now, tangled together in a way neither of them had asked for and neither of them, he suspected, would now choose to undo.

"Then we'll learn," he said, quietly, echoing words Eric himself had offered only days before. "Together. Whatever that costs either of us."

Outside, the last of the frost was already melting off the tent canvas in the warmth of the small fire Vane had finally allowed himself to light, and somewhere beyond the camp's edge the valley they had fought in that day lay quiet again, the rift sealed, the dead already being counted and named by soldiers who would carry those names the way soldiers always did — carefully, and not for very long, because carrying them any longer than necessary was how a person survived a life like this one. Vane thought of Corven, unhurt this time, and of the two boys he'd crossed the field to save, and found that the ache in his shoulder felt, for once, like an entirely fair price.

*"You're doing the thing again,"* Eric said, gently. *"Thinking too loudly."*

"Occupational hazard," Vane said, echoing him, and felt, rather than heard, something that might have been a laugh ripple through the strange, shared space between them.

*"Together,"* Eric agreed, and there was something in the word this time that felt less like a plan and more like a vow, spoken too early, perhaps, for either of them to name it properly — but spoken all the same.
