The ride was short, a flea-hop to the nearest clearing station. The dropship skimmed over the ground. The casualties lay like two statues, locked into their rigid suits. The ship had no medical facilities. It couldn’t even be pressurized, so the casualties couldn’t be taken out of their skinsuits.

The orderly was cheerful; he actually whistled tunelessly as he flew the ship. Pirius shut down his comm loop.

After a couple of minutes, more dropships came into sight, other bubbles of light skimming over the asteroid’s battered surface, converging from all over the Rock. A crude traffic control system cut in, and Pirius’s dropship joined a queue. Soon they were so close to the ship in front Pirius could see its passengers, and their bewildered expressions. Ships streamed the other way, too, dropships heading back out across the Rock to ferry in yet more casualties.

The clearing station had been set up in a wide impact crater. A pressurized dome perhaps a kilometer wide sat in the crater like a huge droplet of water, its skin rippling languidly. It was marked with a tetrahedral sigil, the symbol of free Earth.

The dome was studded with airlocks, to which ships came nuzzling up. Some of them were dropships, others larger boats; there was even a captain’s corvette. The ships rose steadily toward a fleet of Spline craft which drifted far above, fleshy, patient moons. Pirius could see movement inside the dome, through its translucent walls: it was a hive of frantic activity. But there was commotion outside as well, and the surface of the Rock around the dome was covered with glistening rows, as if it had been plowed up, like a big nano-food farm.

Pirius expected his own dropship to dock with one of the dome’s ports. He was surprised when the little craft began to descend a few hundred meters short of the dome. It came down on a patch of bare dust, a landing site hastily cordoned off and marked with winking globe lamps.

The hull popped open, and the orderly, still businesslike and cheery, asked Pirius to give him a hand with the casualties. They set Cohl and Tili in their rigid suits down on the bare ground.

All around the ship, troopers were lying in the dirt, their skinsuits glowing orange or red. This was what Pirius had glimpsed from above, what he had thought looked like the furrows of a plowed nano-food farm. The furrows were rows of wounded, thousands or tens of thousands of them, lying patiently in the dirt, waiting for treatment.

“It’s always like this,” said the orderly.

Pirius began to see the process. The wounded were brought here from all over the Rock. On arrival, they were organized into these rough rows. Close to the dome’s walls, tarpaulins had been cast over the dirt, and there were even a few beds. But out here you just had to lie in the asteroid dirt, still locked in your skinsuit, without so much as a blanket beneath you.
