CHAPTER EIGHTEEN

  The Kinetic Sled

  Falling is a state of transition; landing is a state of impact. Between the two lies whatever you can do with geometry.

  The gradient was seventy degrees—not a cliff, but close enough that gravity viewed the distinction as irrelevant. The surface beneath Marcus was a chaotic mosaic of frost-slicked shale, loose scree, and granite outcroppings that had been shaped by ten thousand winters into exactly the wrong configurations.

  He had approximately the time it took to form a clear thought before the question of survival would resolve itself one way or the other.

  "You are currently accelerating," Mag said. Her voice was sharp, stripped down to information. "The film is holding but the geometry is inconsistent—you are pulsing the pressure rather than maintaining a constant layer. If you don't stabilize it, the stone will find the gaps."

  He stabilized it. The problem was that stable meant uniform, and uniform at this speed meant he could feel every irregularity in the shale as a vibration transmitted through the air film into his spine. Not dangerous in itself. Accumulative over distance.

  Think about the problem, not the vibration.

  On Earth, he'd once reviewed automotive safety data for an infrastructure grant—the kind of dry technical work that he'd been very good at and had not, at the time, imagined would ever be directly applicable to his body sliding down a mountain at speed. The principle was the same: the goal was to manage kinetic energy, to bleed it off in stages rather than all at once. A body that absorbed impact gradually survived. A body that absorbed it at once did not.

  He had the air. He had two kilometers of slope. He had the ability to create resistance—not from the front, which would flip him, but from behind, concentric rings of pressurized air that the momentum would have to push through.

  "Shelf ahead," Mag said. "Three hundred meters. Granite. At your current velocity the impact is non-survivable."

  "Steering?"

  "Shift the pressure distribution under your left side. More weight on the air to the left, body pivots right."

  He did it. The world tilted sickeningly as he curved around the shelf, the air from his passage making a sound like tearing paper. Close enough that he could have touched the rock.

  He built the resistance structure behind him and felt the deceleration push through his chest—not a single shock but a graduated series of them, each one a bit softer than the last as the air dissipated the energy in layers. His head snapped forward. His vision grayed at the edges. The scar on his side, which had been healing for six weeks now, complained with a specific intensity that told him it was not healing anymore.

  This story has been taken without authorization. Report any sightings.

  He hit the flat ground of the lower ledge and tumbled.

  Shoulder. Hip. The sharp impact of a rock he hadn't seen coming. Momentum carrying him another twenty meters through mud and frozen moss before the ground finally won the argument.

  Silence.

  Marcus lay still. He couldn't feel his legs. He could feel his heartbeat—slow and heavy, like something hitting the inside of a drum from far away.

  He did an inventory. Left shoulder bruised badly, possibly worse. The scar had pulled open. His fingers were numb from the cold. His mana channels felt like they'd been scrubbed with gravel.

  He was alive.

  "Aldric?" he thought.

  "Standing at the top of the descent," Mag said. Her voice had its usual quality restored, but something in it was quieter than usual. "Looking into the dark. He is not following. The slope makes the attempt inadvisable and he is a man who calculates advisability carefully."

  "He'll go around."

  "Yes. He has Cinder and the long route. You have two kilometers of lead and the fact that you are still breathing when the mathematics suggested otherwise." A pause. "Get up. The lights you saw from the plateau are no longer theoretical."

  Marcus forced his eyes open.

  He was at a lower elevation—the mist was thinner here, the air fractionally warmer. And there, far below in the twilight valley, the lights were still there. Steady, artificial gold. Not amber hunter-stones.

  A city.

  "Arcanis," Marcus said. His voice came out rough and small.

  "The Kingdom of the Mages," Mag said. "A place where what you've learned will be viewed as a curiosity, and what I represent will be viewed as a threat. Enjoy the view. It is, in all probability, the last uncomplicated moment you will have for some time."

  Marcus didn't move. He lay in the frozen moss and looked at the lights and felt something shift in the architecture of his chest that wasn't the limiter and wasn't the wound and wasn't exhaustion.

  It was the end of one kind of problem.

  He had learned, in two years of policy work, that the end of one kind of problem was very rarely the beginning of nothing.

  ? ? ?

  At the top of the slope, Aldric Vane held his Glow-Stone over the edge.

  The light didn't reach the bottom. But it reached far enough to show him the path Marcus had taken—a smooth, polished line in the shale where the air film had prevented the rocks from being disturbed. Not a tumble. Not a scramble. Something controlled.

  "He didn't fall," Aldric said quietly. "He flew."

  He held the Glow-Stone for a long moment, looking at the empty dark below, and thought about all the categories his training had given him for what mages were and how they worked. He thought about the sheep. He thought about the charcoal burner's axe, which he'd found when he'd passed the hut—the recalibrated wedge angle, the perfect balance, the clean splits in the woodpile that had no magical signature at all.

  He thought about a fifteen-year-old who had been trying to become a farmer.

  The world is changing, Nessa, he thought, looking toward the distant lights of Arcanis. And I am not certain the wall was built for what's coming.

  He turned Cinder and started the long descent of the switchbacks. He had his mandate. He had the file. He had seventeen years of practice at closing cases that needed closing.

  The gap wasn't growing anymore.

  The gap was gone.
