Caleb had the spreadsheet open before Glen finished the sentence.
"That’s three days minimum travel through hostile wild, plus an indeterminate interior duration inside a pre-System structure of unknown spatial parameters, plus three days return assuming equivalent travel conditions and no degradation of your physical state." He was typing while he talked, fingers moving on the tablet in that rapid staccato Glen had come to recognize as Caleb thinking out loud. "Variables I can’t account for: time dilation inside the Tower, structural integrity of the ring as a navigation aid, corruption density along the northern route, caloric requirements during sustained combat against self-improving constructs."
"Caleb."
"Mm."
"I haven’t even told you everything yet."
"I know. I’m building the framework. The framework doesn’t change. Fill in the details as they come." He looked up, and behind the data-gleam in his eyes there was something else — worry, pushed down deep where Caleb kept all his inconvenient emotions, but there. "Your mom told you to go."
"She told me it exists. The decision’s mine."
"The decision’s yours and you’ve already made it and you’re going to leave tomorrow and you want me to build you a packing list." Caleb nodded to himself more than to Glen. "Right. Okay. Let’s start with the armor."
They were in the compound’s lower workshop, the one the engineering team had claimed after the First Wave. It smelled like solder and cold coffee and the particular ozone tang of mana-infused metal cooling after a repair pass. Half the overhead lights were out — the team had cannibalized them for parts two days ago — and the working lights cast everything in a flat industrial white that made Caleb’s face look like a blueprint.
Glen’s armor sat on the stand in the center of the room. It looked worse than it was. The chestplate had a crack running from the left shoulder to the sternum, courtesy of a Commander who’d gotten closer than Glen liked to remember. The right greave was missing a section of plating entirely, torn away when he’d used the leg to block something he shouldn’t have blocked with a leg. The gauntlets were intact but the mana channels carved into the left one were scored, the fine lines clogged with dried blood and something darker that Glen didn’t want to identify.
"Engineering says full repair is twelve hours," Caleb said. "That’s if nothing else goes wrong, which, based on the last twelve hours of their track record, something will. I told them to prioritize the chestplate and the mana channels. The greave we can field-patch. You don’t need pretty, you need functional."
"I never need pretty."
"I know. That’s why I’m telling you instead of asking you." He tapped something on the tablet. A checklist appeared on the wall screen behind him — Glen’s armor schematic with damage zones highlighted in red and repair priorities in amber. "They’re welding the crack now. Reinforcing it beyond original spec, actually. Marquez — the lead, the one with the braids — she said the original chestplate was underbuilt for the kind of output you’re generating. She wants to add a secondary mana dispersion layer."
"Will it work?"
"She says yes. She also says it’ll add four hundred grams of weight and she understands if that’s a dealbreaker for a Hunter who moves like you do. I told her four hundred grams is nothing. She said four hundred grams is the difference between dodging and not dodging at close range. She’s not wrong." Caleb paused. "I told her to add it. You can always strip it if it slows you down. Better to have the option."
Glen looked at the armor. The engineering team moved around it in a quiet choreography — Marquez at the chestplate with a welding rig that burned mana-blue, her assistant holding a tablet that tracked thermal spread in real time, a third person Glen didn’t the name of sorting replacement plating by weight and mana conductivity on a bench against the wall. They worked like people who’d done this before. Not this exactly — this was unprecedented — but the shape of it. Fix the thing. Fix it fast. Fix it good enough to keep someone alive.
"Skills check," Glen said.
Caleb swiped the tablet. The checklist on the wall changed.
"Thunder Phantom Step, B-Rank, stable. No degradation since the First Wave. Predator Domain, A-Rank, stable, but I want to flag something — your usage patterns shifted during the General fight. You pulled wider than you’ve ever pulled. The Domain held, but the recovery cost was higher than your previous records suggest is sustainable. If you’re going into a combat trial, you need to pace it."
"I know."
"You know. I’m writing it down anyway because writing it down is how I stop my hands from shaking." Caleb said it flat, no self-pity, just fact. "Shadow Step, B-Rank, stable. Void Touch, passive, stable — though ’stable’ is a generous word for something the System can’t even see. Enhanced Regeneration, B-Rank, stable. Iron Lungs, C-Rank, stable. Ash Resonance, Rare passive, stable." He looked up. "All five slots full. No room for anything the Tower gives you."
Glen had been thinking about that. "The Tower doesn’t give skills. It gives something else. Strength. Real strength. The kind that doesn’t sit in a slot."
"According to your mother."
"According to my mother."
"Who hasn’t been inside the Tower in eighteen years and whose information about its current internal state is, by her own admission, secondhand inference based on the Tower’s theoretical unchanging nature." Caleb held up a hand before Glen could respond. "I’m not arguing. I’m calibrating. If the Tower doesn’t give slot-based skills, then whatever it gives has to integrate some other way. Through the void, maybe. Through the ring. Through something we don’t have a model for. Which means I can’t plan for it, which means I can’t protect you from it, which means—"
He stopped. Took a breath. Pushed the worry down again. Glen could see the effort it cost him.
"Which means you go and you adapt and you come back and you tell me what happened so I can build the model after the fact." Caleb managed a thin smile. "I hate that. You know I hate that."
"I know."
"Good. Now — med kit." He swiped again. A new list appeared. "Standard field trauma kit, upgraded. I’ve added two additional coagulant injectors, a mana-salve patch rated for A-Rank tissue damage, a thermal blanket because the northern wild drops below freezing at night and your Iron Lungs don’t help with cold, and a three-day ration pack. Calorie-dense. Tastes like compressed cardboard. I don’t care. Eat it."
"You’re packing me a lunch."
"I’m packing you a survival loadout that happens to include food. Don’t make it weird." Caleb set the tablet down on the bench and rubbed his eyes under his glasses. "Glen. I’ve run the numbers six ways. Travel time, combat duration, rest cycles, caloric burn at sustained B-Rank output. The margins are thin. Not impossible. Thin. If the Tower keeps you longer than three days internally, your return window shrinks. If the shield drops below ninety percent while you’re gone, the wild starts pressing the edges. If the court’s response force arrives before you’re back—"
"Then someone else holds the line."
"There is no one else. That’s the problem. You’re the shield. You’re the unclassifiable. You’re the only thing between this city and whatever’s coming, and you’re walking away from it for six days minimum on a gamble that an ancient tower will make you strong enough to matter."
Glen let the silence sit. The welding rig hissed. Marquez muttered something to her assistant about thermal bleed.
"Caleb."
"Yeah."
"If I stay here and wait for the court to send something worse than a General, what happens?"
Caleb didn’t answer. He didn’t need to. They both knew the math. Standing still meant dying slower.
"Right," Caleb said. "Right. Okay. The med kit goes in the pack. I want you to check in by signal flare if you hit the corruption line and there’s a patrol in range. There won’t be, but try anyway. And Glen —" He picked the tablet back up. Held it against his chest like a shield of his own. "Come back with data. Whatever the Tower does to you, whatever you feel, whatever changes — I need it. I need to understand it. Not because I’m curious. Because the next time you walk into something like this, I want to have a model that works."
"I’ll bring you data."
"Bring me yourself first. Data second."
Glen nodded. Caleb nodded back. That was as close to a goodbye as either of them was going to get in a workshop that smelled like solder, and they both knew it.
The war room was two floors up, past the medical bay and the creaking stairwell the engineers kept promising to fix. It had been a conference room once — Glen could still see the ghost of a whiteboard on one wall, the outline of someone’s old project plan bleeding through three coats of paint. Now it had maps. The shield’s perimeter, the wild’s corruption front, the projected paths of the court’s forces. Caleb had built the maps. Caleb built everything that could be built from data.
Seraphina Vance stood at the head of the table. She hadn’t sat down. She rarely sat. Her posture was perfect in the way that cost something — spine straight, shoulders level, hands clasped behind her, the stabilizer at her throat catching the light with every breath. The core crack held. The stabilizer held. Both of those facts were quiet miracles that everyone in the room understood and no one mentioned.
Vera Ashford sat at the table with her boots up on the edge, leaning back in her chair with the easy looseness of someone who’d never met a room she was afraid of. Her hair was pulled back in a rough knot. She was twenty years old and S-Rank and she wore both of those facts like armor that fit perfectly and needed no adjustment.
Isla sat at the far end. Hands on the table. One fist closed, the fingers of her right hand curled in against her palm, the knuckles white. She said nothing. She’d said nothing since Glen walked in.
"The Black Tower," Seraphina said. She said it like she was reading a report aloud, which she probably was — she’d have had the intelligence file pulled before Glen arrived. "Pre-System proving structure. Northern wild, past the dead forest. Your mother’s intelligence places it three days’ travel. You intend to walk it alone."
"Yes."
"The court’s response force is en route. Estimate based on signal intercept — Caleb’s work — puts their arrival at five to seven days from now, depending on composition. If they send another General, you have no margin. If they send something we haven’t seen, you have negative margin." She looked at him. Her eyes were steady, precise, and underneath them was the grief she carried for Elias, packed down so tight it had become structural. "I’m signing off. Not because I think it’s safe. Because standing still is worse."
"Thank you."
"Don’t thank me. Come back with enough strength to hold this city or don’t come back at all. I don’t have room for partial victories right now, Glen. I don’t have room for anything except results." She picked up the file — actual paper, because Seraphina didn’t trust digital for anything that mattered — and signed the bottom of the page. One clean line. "Go."
Vera swung her feet off the table. "When you get back," she said, and her voice had that particular warm-competitive edge she only used with him, "we should spar. I’ve been wanting to test myself against that void thing you do. It looks cheating and I want to know if it is."
"It is."
"Good. I like a challenge." She grinned. It was the grin of someone who treated danger like a sport and meant it, and beneath the sport there was real interest — the kind that watched him across rooms and leaned a little too close when she talked and never once pretended it was accidental. "Don’t die out there, unclassifiable. I’d be bored."
"I’ll do my best to survive your entertainment schedule."
"See that you do." She tipped an imaginary salute. S-Rank, twenty years old, and absolutely certain the world would bend for her if she was interesting enough. Glen envied that, a little. He’d never been certain of anything except the next step.
Isla hadn’t spoken. Glen watched her from across the table and she watched him back, her expression so controlled it could have been carved. The closed fist on the table hadn’t moved. The knuckles were still white. She was holding something in — a word, a question, a feeling she’d already decided not to name — and the discipline of that holding was written in the tension of her wrist.
He didn’t push. Not here. Not with the others.
The meeting ended the way their meetings always did — Seraphina leaving first, Vera leaving loud, Caleb staying behind to adjust the maps. Isla left last and quiet, and she didn’t look at Glen on the way out, and the not-looking was louder than anything she’d said.
Evening found him on the roof again.
The city had gone dark except for the shield’s indigo glow and the scattered points of light below it. The engineering team had finished the chestplate — Marquez had signed off with a note that read "good for two ranks above your last fight, don’t test three" — and the armor sat downstairs, repaired, heavier by four hundred grams, ready. The pack was ready. The med kit was ready. Caleb’s ration packs, dense and terrible, were tucked into the side pocket where Glen could reach them without stopping.
He stood at the railing. The wind was colder now. The shield pulsed.
He heard her before he saw her. The faintest sound of footsteps, measured, deliberate — not Mary’s quiet cane-step, not Vera’s confident stride. Isla’s step. He’d learned to tell. She moved like someone who’d been taught to take up exactly as much space as she intended and not an inch more.
She stopped beside him. Didn’t lean on the railing. Stood with her hands at her sides, both of them open now, the fist from the war room gone. He noticed. He noticed everything about Isla, and he didn’t know what to do with any of it.
They stood in silence for a while. The shield pulsed. The wild waited to the north.
"You’re leaving at dawn," she said. Not a question.
"Dawn."
"The northern route. Past the ridge. Through the dead forest. Into the corruption line." She said each landmark like she’d memorized the map. She probably had. "Three days. Alone. Into a structure your mother barely survived, carrying a ring you don’t fully understand, to be tested by the blood of the things that built the Lost."
"When you put it like that, it sounds bad."
"It is bad. I’m not going to pretend it isn’t because you prefer your danger dry-witted." Her voice was precise, aristocratic, the words chosen the way a surgeon chooses instruments. But there was a hairline fracture in the control tonight. Something underneath, running parallel to the surface, and Glen could feel it the way he felt the ring’s warmth — not with normal senses, with something the void had given him.
"Isla."
"Come back."
Two words. She said them quietly, in that register she used when things cost her, and Glen heard what they weighed. Not a command. Not a request. Something between a wish and a statement of fact, spoken by someone who had decided not to need anything and was discovering, in the dark, on a rooftop, that she might have been wrong.
He turned to face her. She didn’t turn to face him. She kept her eyes on the north, on the dark line where the wild began, and the shield’s light caught the line of her jaw and the set of her mouth and the way her throat moved once around something she wasn’t going to say.
"I’ll come back," Glen said.
She nodded. Once. Small. The fracture closed over, smoothed back down under the control, and she was Isla again — precise, contained, unreadable to anyone who wasn’t standing close enough to feel the heat of the thing she’d buried.
"Good," she said. "I’ll expect a full debrief. Caleb will want data. I’ll want the parts Caleb’s model can’t hold."
"The parts that don’t fit."
"The parts that are yours." She looked at him then. Just for a second. Her eyes were dark and steady and there was something in them he couldn’t name and didn’t try to, because naming it would make it real and he had a tower to climb. "Don’t let the Tower keep you. You’re not one of the Lost. You’re not a construct. You’re Glen. Remember that on the fifth floor."
She said it like she’d read the intelligence file. She probably had. She’d read it and she’d found the part about the identity test and she’d distilled it down to four words — you’re Glen, remember that — and handed them to him like a key, the way Mary had handed him the ring.
"Goodnight, Glen."
"Goodnight, Isla."
She left the way she’d come, measured and deliberate, and the rooftop was quiet again, and the wind blew, and the shield pulsed, and the north waited.
Glen stood there a long time after she was gone.
He thought about the Tower. Five floors. Combat, willpower, mana control, mental fortitude, identity. He thought about Mary’s hands and the way she’d held the cane and the thing the Tower had cut out of her. He thought about Caleb’s spreadsheet and the thin margins and the ration packs that tasted like cardboard. He thought about Vera’s grin and Seraphina’s clean signature and the way she’d said I don’t have room for anything except results, and he understood that was grief talking through the shape of command, and he respected it.
He thought about Isla’s closed fist. He thought about the way she’d said come back, and the way he’d said I’ll come back, and how two sentences could hold more weight than a shield.
He lifted his hand. The black ring sat on his finger, warm, steady, older than the System, older than the Hunters, made by his mother in a tower that tested what you were. It pulsed once under his thumb. A heartbeat. A recognition. A door waiting to open.
Tomorrow he’d walk north. Three days through the wild. Past the corruption. Into the dark.
Tomorrow the Tower would ask him who he was, and he’d have to answer from the thing underneath all of it — underneath the void, underneath the skills, underneath the shield and the rank the System couldn’t give him. The thing that was just him. Working-class. Sardonic. Tired in a way sleep didn’t fix. Carrying a ring and a name and a city full of people who didn’t know how thin the margin had gotten.
He closed his hand around the ring. Squeezed once. Let go.
The shield held the city. The wild held its breath.
Glen was ready.
Dawn would come, and he would walk, and the Tower would wait, because the Tower always waited, and he was done waiting with it.
