"Friction."

  Garrett's voice cut through the morning air like a blade through silk. He stood at his workbench, a gear the size of Aldric's palm held up to the light.

  "Say it."

  "Friction," Aldric repeated.

  "Good. Now tell me what it means."

  Aldric hesitated. He'd arrived at the forge an hour ago, still stiff from the climb, his mind churning with questions. Garrett had barely acknowledged his presence before launching into what felt like an interrogation.

  "Resistance," he said finally. "When two surfaces rub against each other, there's resistance. It slows things down."

  "Slows things down." Garrett set the gear on the table with a clunk. "That's what they teach you at the Order? 'Slows things down'?"

  "I didn't—"

  "Friction is loss." Garrett's voice was sharp, impatient. "Every time force moves through a system, some of it bleeds away. Heat. Sound. Vibration. You push ten units of force into a lever, you get eight out. Where did the other two go?"

  "Friction."

  "Exactly." Garrett picked up the gear again, turning it over in his fingers. "The question isn't whether you lose force. You always lose force. The question is how much, and where, and whether you can do anything about it."

  He set the gear down and walked to a shelf, pulling down a roll of parchment. This one was different from yesterday's—larger, covered in more complex diagrams. He spread it on the table and weighed down the corners.

  "This is a gear train," he said, pointing to a series of interlocking circles. "Power comes in here, moves through the gears, comes out there. Simple enough. But look at this." He traced a line with his finger. "Each gear has friction at its pivot point. Each contact between gears has friction. By the time the force reaches the end..."

  "It's weaker."

  "Weaker. Yes. But how much weaker?" Garrett looked at Aldric. "That's what matters. If you know how much you're losing, you can account for it. Plan for it. Maybe even reduce it."

  Aldric studied the diagram. The gears were drawn with precise angles, arrows indicating the direction of force. It was like nothing he'd seen in the Order's library—nothing to do with mana, or channels, or the flow of energy through the body.

  And yet.

  "Can I ask something?"

  Garrett grunted. "You're going to anyway."

  "Why does this matter? To you, I mean. You've been working on this for forty years. What's the point?"

  The old man was quiet for a moment. His eyes moved over the diagram, then to the mechanical arm on the nearby table, then back to Aldric.

  "Because I want to build something that works," he said finally. "Not a puppet. Not a toy. Something that moves because it understands how to move. Something that doesn't need a mage to pour mana into it every five seconds." He snorted. "They think they're so clever, throwing energy around. But they don't understand efficiency. They don't understand how to make something last."

  He turned back to the diagram.

  "Every machine I've ever built has the same problem. It works for a while, then it breaks, or it wears out, or it just... stops. Because I can't figure out how to make the force flow right. How to minimize the loss." He looked at Aldric again. "You know what that's like?"

  Aldric thought of his body-tempering. The endless hours of practice. The feeling of mana pooling in his muscles, his bones, his blood—and the sense that most of it was going nowhere. Dissipating. Wasted.

  "Yes," he said. "I know what that's like."

  Garrett studied him for a long moment. Then he nodded, as if something had been confirmed.

  "Good. Then maybe you'll actually learn something."

  ---

  The morning stretched into afternoon.

  Garrett talked. Aldric listened. And slowly, painfully, the concepts began to take shape.

  Levers. A lever was simple—force applied at one point, transmitted through a rigid bar, delivered at another. But the position of the pivot changed everything. Too close to the load, and you needed more force to move it. Too far, and you lost distance. The trade-off was absolute.

  "Mechanical advantage," Garrett said, drawing a diagram on a scrap of parchment. "You can multiply force, but you pay for it in distance. Or you can multiply distance, but you pay for it in force. There's no free lunch."

  Aldric nodded. He was beginning to see the pattern.

  "What about... multiple levers?"

  Garrett's eyes sharpened. "What about them?"

  "If you have more than one. Connected. Does that change anything?"

  "It changes everything." Garrett set down his charcoal. "Multiple levers mean multiple pivot points. Multiple places for friction. Multiple opportunities for force to bleed off in the wrong direction." He paused. "But it also means multiple paths. Multiple ways to distribute the load."

  He stood abruptly and walked to a corner of the workshop, rummaging through a pile of scrap metal. After a moment, he returned with a strange contraption—a series of metal bars connected by joints, arranged in a rough approximation of a human arm.

  "This," he said, holding it up. "I built this twenty years ago. Thought I'd figured out the angles. Thought the force would flow through cleanly."

  He pulled a lever at the base. The arm jerked, the joints moving in a sequence that looked almost natural. But halfway through the motion, something caught—a grinding sound, a shudder—and the arm stopped, frozen in an awkward position.

  "Friction," Garrett said flatly. "The force builds up at this joint—" he pointed "—and instead of moving through, it bleeds off. The whole thing locks up."

  He set the arm on the table with a clatter.

  "Forty years, and I still can't get it right."

  Aldric stared at the frozen mechanism. The joints. The angles. The force that should have flowed through but didn't.

  Multiple paths. Multiple places for friction. Multiple opportunities for force to bleed off.

  Something was clicking into place in his mind. Not fully formed—not yet—but the shape of an idea, waiting to be understood.

  "Can I see that?" he asked.

  Garrett raised an eyebrow but handed over the mechanism. Aldric turned it over in his hands, studying the joints. They were precise, well-crafted, clearly the work of a master. But there was something wrong with the angles. He couldn't say what, exactly—just a sense that the force was being asked to move in a direction it didn't want to go.

  "The mana," he said slowly. "In my body. It moves through... channels, I guess. I don't know what else to call them. But it doesn't move in straight lines. It curves. Loops. Comes back on itself."

  Garrett was watching him closely now.

  "And?"

  "And sometimes it feels like it's building up in places. Like it wants to go somewhere but can't." Aldric frowned, trying to find the words. "Like there's... resistance. Not physical resistance. Something else."

  "Friction," Garrett said quietly.

  Aldric looked up. "What?"

  "You're describing friction. Not between surfaces—between flows. The mana wants to move one way, but the path you're giving it goes another. So it bleeds off. Wastes itself."

  The words hit Aldric like a physical blow.

  Friction. Between flows.

  He'd spent two years trying to push more mana through his body. More intensity. More focus. More everything. And all along, the problem wasn't how much he was pushing—it was where the paths were leading.

  "Show me," he said. "Show me how to fix the angles."

  ---

  The afternoon wore on.

  Garrett drew diagrams. Aldric asked questions. The old man's patience was limited—his explanations were terse, often interrupted by muttering or sudden tangents—but he didn't send Aldric away.

  "The body isn't a machine," Garrett said at one point, his charcoal moving across parchment. "I can't give you exact angles. But the principle is the same. Force wants to move in certain directions. If you fight it, you lose. If you work with it..."

  He trailed off, drawing a series of curved lines that intersected at odd angles.

  "Look at this. The force comes in here, moves along this curve, and ends up... there." He pointed. "But if you change the angle of the curve—just slightly—the force ends up here instead. Same input. Different output. Because you're not fighting the natural flow."

  Aldric stared at the diagram. The curves. The intersections. The way a small change in angle produced a completely different result.

  The mana doesn't move in straight lines.

  He closed his eyes, focusing inward. The mana was there, as always—a faint warmth in his core, spreading slowly through his body. He'd learned to feel it over the past two years, to track its movement through muscle and bone.

  But he'd never thought about the angles.

  He tried to visualize the paths. The channels the mana followed as it spread through his arms, his legs, his torso. They weren't straight. They curved around bones, followed the grain of muscle, pooled in joints before moving on.

  And in some places, the curves were wrong.

  He could feel it now—a sense of resistance, of mana building up where it shouldn't. Not because there was too much, but because the path was asking it to turn too sharply. To go where it didn't want to go.

  Friction. Between flows.

  His eyes snapped open.

  "I think I see it."

  Garrett, who had been muttering over a gear mechanism, looked up. "See what?"

  "The problem. In my body." Aldric's voice was tight with excitement. "The mana isn't flowing wrong because I'm weak. It's flowing wrong because the paths are wrong. I've been trying to push more through, but I should be... changing the paths. Making them smoother."

  Garrett's expression didn't change. But something in his eyes sharpened.

  "Show me."

  Aldric stood. He moved to the center of the workshop, where there was space to move. He closed his eyes again, focusing inward.

  The mana was there. He reached for it, drawing it up from his core, directing it through his right arm. The familiar warmth spread through his shoulder, his bicep, his forearm—

  And there. Just below the elbow. A spot where the mana always seemed to catch, to pool, to dissipate before reaching his hand.

  He'd assumed it was a weakness. A flaw in his body that he couldn't overcome.

  But now he could feel the angle. The path curved sharply at that point, forcing the mana to turn almost back on itself. No wonder it bled off.

  He adjusted. Not pushing harder—pushing differently. Visualizing a smoother curve, a gentler angle. The mana resisted at first, habit pulling it toward the old path. But gradually, slowly, it began to shift.

  The warmth flowed through his arm without the familiar catch. It reached his hand, his fingers, spreading through them with an intensity he'd never felt before.

  He opened his eyes.

  His right hand was glowing faintly—a pale white light, barely visible, but unmistakably there.

  Garrett stared.

  "That's..." The old man's voice was strange. Not dismissive. Not grumbling. Almost... awed. "That's Common-grade. At least."

  Aldric looked at his hand. The glow faded as he released the mana, but the sensation lingered—a sense of rightness, of something clicking into place that had been wrong for years.

  "I've been doing it wrong," he said quietly. "For two years. I've been doing it wrong."

  "You've been doing it inefficiently," Garrett corrected. His voice had returned to its normal gruffness, but his eyes were still fixed on Aldric's hand. "There's a difference. You weren't weak. You were just... bleeding force in the wrong places."

  Aldric flexed his fingers. The memory of the sensation was already fading, but he knew he could find it again. The smoother path. The gentler angle.

  Friction. Between flows.

  "Thank you," he said.

  Garrett snorted. "Don't thank me. I didn't do anything. You're the one who figured it out." He turned back to his workbench. "Now get out. I have work to do."

  Aldric smiled. It was a small smile, barely visible, but it was real.

  "I'll come back tomorrow."

  "If you want." Garrett didn't look up. "But don't expect me to teach you. I'm not a teacher. I'm a craftsman."

  "I know."

  Aldric walked to the door. He paused at the threshold, looking back at the cluttered workshop, the old man hunched over his mechanisms, the diagrams scattered across every surface.

  "Garrett."

  "What?"

  "The arm. The one that locks up." Aldric pointed to the frozen mechanism on the table. "The angle at the second joint. It's too steep. If you curved it more—gave the force a smoother path—it might not catch."

  Garrett's head snapped up. He stared at Aldric for a long moment, then at the mechanism, then back at Aldric.

  "Get out," he said. But there was no irritation in his voice. Only surprise.

  Aldric stepped outside.

  ---

  The sun was setting as he climbed the ridge back toward the Cloudridge Order.

  His mind was racing. The sensation of the mana flowing smoothly through his arm—the glow, the intensity, the rightness of it—played over and over in his memory. Two years of frustration, of slow progress, of feeling like he was pushing against a wall that wouldn't move. And all along, the problem had been something he couldn't see.

  The angles. The paths. The friction between flows.

  He thought of the Ironwing Pact inspector, the threat looming over the spellblade disciples, the stipend disparity and the locked technique manuals and the endless weight of being "worthless."

  None of that had changed. The inspector was still coming. The system was still broken. He was still at the bottom.

  But something inside him had shifted.

  He reached the top of the ridge and paused, looking back at the valley below. The forge was just visible through the trees, a thin thread of smoke rising from its chimney. Garrett was in there, probably already forgetting that Aldric had existed, lost in his obsession with mechanisms that walked on their own.

  Not a teacher. A craftsman.

  Aldric smiled again. It was a strange thing, finding help in the last place he'd expected. A hermit blacksmith who didn't believe in magic. A workshop full of gears and levers. A framework that had nothing to do with arcanism and everything to do with how force moved through a system.

  He turned and started down the slope toward the Order. Tomorrow, he would return to training. He would test what he'd learned, refine it, see how far the principle could take him.

  And when the inspector came—when the system tried to crush him again—he would be ready.

  Friction. Between flows.

  He drew a slow breath, let it out, and kept walking.

  ---

  An old man's mechanical wisdom. A spellblade's breakthrough. And a glimpse of what might be possible when you stop fighting the current and start changing the channel.

  But the inspector is still coming—and Aldric's new understanding is about to face its first real test.
