"And you fought splendidly, Roman. Superbly."

The Commander wore body-covering tights whose fabric was the same shade of blue as the mobile fountains. His face was the only part of him which the suit did not cover, and the flesh there returned sunlight in a direct reflection like that of metal or glass when the angle was right. The hands that gripped the reins, and the feet that rested on the pegs which the Romans were learning to call stirrups, each seemed to have six digits beneath the soft blue cloth.

"I don't-" the tribune said. "Understand," Vibulenus would have continued, but that would be pointless. "Where are we?" he asked instead, the timbre of his voice rising with desperate emotion instead of rhetorical effect.

"That doesn't matter," the Commander replied simply. Probably that answer would have done as well for the other statement, the one Vibulenus had swallowed. "You won't be asked to do anything unfamiliar to you. Anything-" his six-fingered hand gestured broadly toward the wrack of bodies lying on the far slope, giant warriors strewn like driftwood storm-tossed on a beach "-anything but what you do so well. And-" the Commander withdrew his hand and straightened in the saddle "-you will become immortal."

The sun glittered off a variety of new facets as the Commander's face drew up in what might be a grimace.

"That is," he added, "your bodies will not age. Not ever again."

His lips did not move when he spoke. The flawless Latin of his statements came from a black embroidery on the fabric covering his throat.

There was another sound in the air, like the suction wheeze of the beasts' equipment, but louder and from above. Over it, Vibulenus shouted, "Will you send us home? We can pay you. Rome will pay you a rich ransom."

As she had not ransomed the soldiers of Regulus, captured in similar ignominy, but even a slave could hope, could pray…

"Release you?" the Commander paraphrased. He squealed again, in apparent humor. "Oh, no, Roman. You're far too valuable for that. And now, I must report to my superiors. You'll be given further details when you've mustered aboard the vessel for your next assignment."

The roar from above was expanding into echoing thunder beside which the warriors' vibrating bronze sheet faded to pale mockery and even a true storm would have been inaudible. Vibulenus looked up as men all over the valley were looking, shading their eyes with a hand or simply gaping in open-mouthed wonder.

The young tribune had guessed that they had come to this place in a ship, a vessel that sailed upon land as those with which he was familiar sailed on water. The thing that roared a hole in the sky as it slowly descended was a ship like that which the legion had marched aboard in Parthia, but it did not slide over the land.

"What-" the tribune began and paused when he realized that, even if he shouted, his words could not possibly be understood. Some legionaries were throwing off their helmets so that they could clamp both palms over their ears.

As if he were speaking within the tribune's skull, the Commander's voice answered the incompleted question: "Now that we have defeated the king who refused us trading rights, the trading mission can go ahead. But move aside, tribune, or you'll require a full physical rebuild yourself."

Vibulenus caught the hint of a croaked order like that which had opened a path through the bodyguard so that the Commander could speak with the young Roman. He stumbled out of the guards' way as they, having heard the new command as clearly as the tribune had heard the last words directed to him, spurred their huge mounts back across the valley.

The pair of Romans accompanying them yipped and kicked their horses, getting off to a less abrupt start than the carnivores of the guard but falling into a fluid canter that looked more comfortable than the others' loping gait. The remainder of the twenty-strong bodyguard followed, surrounding the blue spark of the Commander. Most of them had raised their visors now that the fighting was over, displaying their bulbous eyes and their broad, expressionless mouths.

The descending ship dropped below the ridge, toward the canyon in which the legion's vessel already waited. For a moment, the thunder was redirected upward and the ground quivered in trying to absorb the noise. Then it muted to a growl and ceased entirely. The silence that followed was so complete that Vibulenus could again hear insects buzzing in his hair, where the tree with which he had collided had sprayed him.

"What's it mean, sir?" begged Clodius Afer. The prospect of battle had made the file-closer tense and irritable, but he was a veteran of other wars. What he had just seen was an object the size of the Circus Maximus, descending slowly through the air as if it were a feather and not something that could hold a hundred and fifty thousand human beings. "What's going to happen?"

"I don't know, Gnaeus,'' the tribune said, using the file-closer's first narne because he knew in his guts that there was no rank or class at a time like this. "But if we wait long enough, maybe we'll find out."

And if what the Commander had said about agelessness were true, they would be able to wait a very long time.

"All right, next lot," said the man whose blue body suit identified him as one of the vessel's crew. In fact, he would have passed in Vibulenus' eyes for the Commander, save that his garment did not cover his skull and there was no shiny surface between his face and the outside world. This crewman called himself the Medic, a diminutive of the word for doctor-medicus. The word was understandable though not a linguistic formation familiar to the legionaries before flashing, headsized floating machines summoned them back aboard.

There was a gassy wheeze; four doors opened in the wall of the room. Romans who had entered the cubicles nervously a moment before stood, bemused and wrapped in dissipating steam. Some of them were working limbs or kneading parts of their bodies.

"Come on, come on," the Medic snapped from behind the piece af furniture-it looked like a writing desk-at which he stood. "Keep it moving or I'll be here all fucking night. And so," he added in an afterthought, "will your buddies."

The four nude men stepped out into the hall proper, still more focused on their own bodies than they were on what the Medic or anyone else might say.

"Hercules!" muttered Clodius to the tribune at his side, "Look at Caprasius. You saw how they near lifted him and his leg into the booth in two loads."

Caprasius Felix, a front ranker of Clodius' century, had run into a cutting weapon of some sort during the battle, wielded with enough strength to sever the bone of his right thigh. Somebody had slapped a tourniquet on the wound, but neither that field expedient nor the amputation which was all surgery could offer such a case was likely to help the victim long.

Two of his fellows had carried him, unconscious from shock and as pale as the belly of a dead fish, into the booth as the Medic directed. Now…

"Well, he's limping," said Vibulenus.

"What in Hades," Caprasius was muttering as he walked toward the marked exit, past the quartet of toad-faced bodyguards who kept order as the returning legionaries processed through the medical check on reentering the vessel. The injured man was clutching his right thigh with both hands. Suddenly, he took the hands away and tried to kick that leg high in the air.

There was a three-inch band of paint or discoloration, bright Pompeian red, around the thigh, but there was no sign of the wound which had gaped to splintered yellow bone. Caprasius stumbled and fell sideways when muscles caught in a way he had not expected, but he was rolling again to his feet before his friends could help him.

"Hades," he repeated, grinning like a man reaching the head of a prostitute's queue. "It works, by Hercules, it fuckin' works."
