The silence after Talene left was the loudest sound Kazuto had ever heard. It was a physical weight, pressing down on everyone. He could see it in their wide eyes, their hunched shoulders. They'd built a roof, and a goddess of fire had just walked up to it and knocked.
He turned to Mavis. Her face was pale, but her mind was clearly whirring. "My quarters. Now."
They walked to the small, carved-out room Mavis used as an office and planning center. She lit a single, fat candle made from lizard tallow. The flickering light made the shadows of her slate diagrams dance on the walls.
"Conceptual entropy," she began, pacing. "She doesn't attack the thing. She attacks the idea of the thing. Your dome is the idea of 'safety' and 'barrier' made manifest. She will try to burn that idea."
"How do you fight that?" Kazuto asked, sitting on a stone stool. "How do you protect a… a thought?"
"You reinforce it," Mavis said, stopping. "With a stronger idea. Your skill isn't just walls. Its name is [Boundless Mercy: Kingdom of Eternal Refuge]. Refuge. Sanctuary. A kingdom. Those are big ideas. Deep ones. Is your idea of safety stronger than her idea of annihilation?"
Kazuto didn't know. He'd never thought of it that way. He'd just used it like a tool. "It's kept everyone safe so far."
"From physical threats. This is different." She chewed her lip. "We need to test it. On a small scale."
"Test how? We can't exactly ask her to burn a teacup first."
"No. But we can simulate it. Sort of." She pointed to a blank spot on the wall. "Make a small barrier. A simple one. A square."
He did. A one-foot square of the transparent barrier appeared on the wall.
"Now," Mavis said. "I want you to focus on that barrier. But not as a wall. As the idea of 'wall.' Its 'wall-ness.' Then, I want you to use your skill to protect that idea. To make the concept of 'wall' here… unburnable."
It sounded like nonsense. But he had nothing else. He stared at the square. He tried to think past the shimmering surface to what it was: a division. A separator of spaces. A promise that 'this side' is not 'that side.' He focused on that promise. He wrapped his will around it, not to make it stronger, but to make it certain. He poured the feeling of the dome's safety, of the trust the dwarves had in it, of the goblins' curious taps, into that one, small concept.

« PROCESSING… »
The small square didn't change visually. But the air around it seemed to… settle. To become more real. The candle flame nearby stopped flickering for a second, as if the very idea of 'air movement' had been politely asked to be still.
Mavis let out a slow breath. "Interesting. There's a… thickening. It might work. On a small scale. The dome is exponentially more complex."
"It's all I've got," Kazuto said, letting the small square fade.
"It's not." Mavis's gaze dropped to the floor beside his stool. "You've got that."
The package. He'd brought it with him, as always. The plain cardboard box sat on the stone floor, the "FRAGILE" stamp facing up.
"It's just a box," he said, but it sounded weak even to him.
"It's the only thing that came with you from your world. The catalyst. You told me the voice called your skill a 'synthesis' of your core concepts. What if the box is part of that? Not the skill, but the… the delivery address?"
Kazuto picked it up. It felt ordinary. Light. He shook it gently. The solid thunk was the same.
"I can't open it," he said. "It's not mine to open. It's for delivery."
"To whom? To where?" Mavis's voice was fierce. "Kazuto, you are in another world. The rules have changed. Maybe the delivery is this. This place. These people. Maybe opening it is how you 'complete' the transaction. How you fully activate whatever this is."
He stared at the box. For weeks, it had been a totem. A piece of home. A reminder of a simpler job. The idea of opening it felt like a betrayal. It was against every rule he'd ever worked by.
"I… I need to think."
He left Mavis's room, box in hand. The basin was quiet, but not still. Elder Leon had everyone—dwarves, Balmond, even the goblins—sitting in a large circle in the central area. They weren't training. They were meditating. Or trying to.
"Breathe in," Leon's calm voice instructed. "Hold the air. Feel its life. Breathe out. Release the fear. Let it go."
Balmond looked like a boulder trying to be a feather. His face was screwed up in intense, furious concentration. A goblin next to him kept peeking one eye open to see if it was doing it right.
Ban was moving through the group, handing out small cups of a sweet, minty tea. "For the nerves," he murmured. "No one faces the end on an empty stomach, or a jittery one."
Kazuto walked to the center, near the well. He set the package down on the ground in front of him. He sat cross-legged, facing it.
What are you?
He remembered the elevator. The rift. The voice synthesizing his skill from his life: [Steadfast Reliability], [Practical Empathy], [Unyielding Patience].
A deliveryman's traits.
The box was a delivery.
Maybe Mavis was right. Maybe the delivery wasn't to this world. Maybe he was supposed to deliver something into it. Himself. His way of being. This… kingdom of refuge.
But the box was physical. It had weight. Something was inside.
He reached out, his fingers hovering over the cardboard seam. His heart hammered against his ribs. This felt bigger than any barrier.
"Master Kazuto?"
It was Kael, the young dwarf. He'd left the meditation circle and approached quietly. He looked at the box, then at Kazuto's face. "Is that… the secret?"
"I don't know, Kael. I think it might be."
The boy knelt down, looking at the box with serious eyes. "My grand-uncle Leon says a tool unused is a weight in your pack. If you carry it, you should use it." He paused. "But he also says you must respect the tool. Understand its purpose."
Kael reached out and, with a touch so light it was barely there, patted the side of the box. "Thank you for bringing us here," he said to it, his voice sincere. Then he stood, gave Kazuto a quick nod, and went back to the circle.
Kazuto stared after him. The simplicity of the gesture cut through his panic. Kael was right. He'd been carrying this thing, protecting it, for weeks. It was time to understand its purpose. Respectfully.
He wasn't going to rip it open. He was going to… complete the delivery.
He placed both hands on the box. He closed his eyes. He didn't focus on the cardboard. He focused on the intent behind it. The sender, whoever or whatever it was. The recipient—this world, this moment, these people. The act of delivery itself, the completion of a journey.
He poured that intent into his skill. Not as a shield, but as a key. A request for understanding.

« SYNCHRONIZING… »
The box didn't open. It glowed. A soft, gentle, white light emanated from within the cardboard, seeping through the seams. The "FRAGILE" stamp shimmered like gold leaf.
Then, without a sound, the seams gave way. The flaps of the box relaxed and fell open.
Kazuto leaned forward, his breath caught.
Inside, nestled in plain grey packing foam, was a single, smooth, river stone. It was perfectly oval, grey with flecks of silver. It was utterly ordinary. Beautiful in its simplicity, but just a stone.
Beneath it lay a folded piece of paper.
His hands trembled slightly as he picked up the stone. It was cool, heavy for its size. He set it down and unfolded the paper.
It wasn't a letter. It was a delivery receipt.
At the top was his own name: Voldius Kazuto. The sender field was blank. The destination field read: Wherever you are needed.
In the 'Item Description' box, written in neat, printed letters, was a single line:
One Foundation Stone. Handle with care. The first brick is yours to lay.
He turned the receipt over. Nothing.
That was it. A stone and a receipt.
A laugh bubbled up in his chest, born of sheer, bewildered relief. It wasn't a weapon. It wasn't a magic artifact. It was a metaphor. A permission slip.
The first brick is yours to lay.
He looked up at the dome, at the people meditating, at the tunnels they'd dug, the gardens they'd planted. They'd already been laying bricks. They'd already been building.
The stone wasn't for building a wall. It was for understanding that he already had.
He picked up the smooth stone, holding its solid weight in his palm. The fear that had clenched his gut since Talene's appearance began to loosen. He didn't have a magical solution. He had what he'd always had: a job to do, a delivery to complete, and people depending on him to do it right.
He stood up. The meditation circle saw him. They saw the open box at his feet, the stone in his hand. A question hung in the air.
Kazuto slipped the stone into his pocket. He picked up the empty cardboard box and the receipt. He walked to the central fire, now just embers. He placed the box and the receipt into the coals. They didn't burn with a normal flame. They dissolved into wisps of silver smoke that spiraled up towards the dome and vanished.
The delivery was complete.
He turned to face everyone. "Dawn's coming," he said, his voice clear in the quiet basin. "Get some rest. We have a long day of not being burned tomorrow."
No grand speech. Just the next item on the list.
But as people began to move, heading to their tunnels, he saw their shoulders were a little straighter. They'd seen him open the mystery. They'd seen him find not a weapon, but a stone. And somehow, that was more reassuring.
He had his first brick. And a dome to protect.
The final test was coming. But for the first time, Kazuto felt like he was reading the correct address.
