The mobile workshop arrived in front of Yantra’s eastern gate when the darkness had not yet ended, but had already lost its strength.

The dirt road climbed gently between two ridges of pale stone, worn down by wind and by the wheels of the vehicles that entered and left the city every day. Far away, behind the last crests, the sky was just beginning to fade. It was not yet light, it was no longer night.

The great vehicle advanced alone, with a low and steady rumble. Its enormous wheels kicked up fine dust, but the road was smooth, compact, packed down by years of fast traffic. Now and then a stone would fly out from under the dark tires and bounce against the metal of the side. The upper platform trembled only slightly, as if the whole machine were a heavy, disciplined animal, used to running without needing to be guided.

Anesh was huddled in a sheltered niche, carved out of the front part of the vehicle, not too exposed to the full wind but close enough to the edge to see the road ahead. He kept his knees hugged to his chest and his back pressed against the metal wall, still warm from the long journey. For hours he had been looking ahead, without knowing exactly what to expect.

At his side, strapped to his waist with a thin belt, was the small wicker container. It was little bigger than a cup, woven from dark and light fibers, closed at the top like a tiny hut. It looked like a fragile object amid all that metal: a nest carried inside a war machine, something almost out of place, almost ridiculous. And yet Anesh kept feeling its presence more than any other weight he carried. Every so often, when the vehicle sped up or when the road changed slope, the basket would gently bump against his side. Nothing could be seen inside, but he knew Ku was there.

He was not sleeping. He didn’t even know if a butterfly could sleep. Ever since she had arrived at the cave, after the night when a light had crossed the sky above Kangen, Ku seemed to live in a kind of continuous, silent attentiveness. She had never pointed the way like a hand. She had not spoken, had not called, had not explained. And yet Anesh had found himself, day after day, following her. He had finally decided to leave the cave where he had taken refuge, then descended along the slopes of Altaluna and the lower roads, until he reached that autonomous vehicle he had boarded, the one that had picked him up as if it too, in some way, had already been part of the journey.

Now the butterfly was motionless. Or perhaps it was he who could no longer sense her movement.

Ahead of them, the gate of Yantra began to emerge from the shadows.

It was not a gate as Anesh had imagined it. There were no solemn towers, no ancient walls, no statues of kings or warriors. It was an immense structure of metal and technical stone, wedged between two rocky walls, made of moving panels, ribs, bridges, rails, counterweights, sensors, side arms, and dark surfaces that barely reflected the first light. It seemed built not so much to defend the city, as to measure everything that entered.

At the center, above the main arch, was the great clock. Anesh saw it even before he read the inscription.

It was enormous, circular, marked by signs that did not quite resemble the clocks of Altaluna. It did not seem to simply indicate time: it seemed to distribute it. Its face was engraved in thin sectors, and each sector seemed connected to a part of the city still hidden beyond the gate. Small lights ran along the outer edge, one after another.

One minute remained.

The vehicle slowed down on its own.

It did not brake abruptly. It let the speed fade little by little, as if responding to an order received from afar. The vibrations of the platform changed, the rumble of the wheels grew deeper, then lower. A series of dim lights came on at the sides of the gate, not to truly illuminate, but to mark lines, edges, heights, distances. A thin beam passed along the side of the mobile workshop, climbed over the closed containers, slid over the platform’s hooks, the folded mechanical arms, the silent control units, the sealed panels.

Then it reached Anesh.

For an instant, the boy closed his eyes.

He felt the technical light pass over his face, his hair, his hands clasped around his knees, the rough fabric of his pants, the belt at his waist, the small wicker container. When the beam touched the basket, something changed. Nothing happened that anyone else could have noticed. No flash, no sudden sound. Only a minimal vibration, like the tremble of a leaf before the wind.

Anesh lowered his gaze.

The basket was still.

But he felt that the butterfly had turned.

Or perhaps it was the world that, for an instant, had turned around her.

He looked up again and then read the inscription.

It was engraved above the gate, beneath the great clock, in wide, clear letters, without ornament. It did not seem like a motto. It seemed like a statement. A law.

You are what you do.

Anesh felt uneasy. He didn’t know why. Those words were false, but not in a simple way. Even in Altaluna they had taught him that actions matter, that a search without action can become mere vanity, that thought must sooner or later touch something. And yet there, above that gate, those words had a different weight. They did not say: what you do reveals something about you. They said: you are this. This and nothing else.

The last light on the dial reached the lowest point.

For an instant, everything stopped.

The road.

The vehicle.

The dust suspended behind the wheels.

The lights of the gate.

Anesh’s breath.

Then the clock struck Solarian zero.

And Yantra began to light up.
