On his final, grief-stricken return from the mountain, Tarquinius had prised the ruby from the hilt of the ancient sword and buried the weapon and the liver in a grove near Caelius' villa. This was partly because he preferred to fight with an Etruscan battleaxe and partly because the fine blade would have attracted too much attention. He was sure that Olenus would have understood. The gem had been worn against his heart ever since.

In deep gloom, he filled a pack and said goodbye to his mother, knowing he would never see her again. Fulvia understood instantly when he mentioned that Olenus had predicted this road for him; nearby his father was lying in a drunken stupor. The young man kissed Sergius' brow and whispered in his ear, 'The Etruscans will not be forgotten.' The sleeping figure rolled over, smiling gently. It lifted Tarquinius' spirits as he walked along the dusty track that led to the nearest road.

A good place to start, Rome had drawn him south. Tarquinius had never visited the capital before and its great buildings did not fail to impress him. He was immediately drawn to the great temple of Jupiter, where he witnessed the priests as they emerged from a reading of the Etruscan libri. The young haruspex burned with rage while watching the Roman augurs pronounce their interpretation of the winds and clouds that day. And it was incorrect. The sacred books stolen from Etruscan cities were in the keeping of charlatans. It crossed his mind to steal the libri, but there was little point. Where would he take them? Copies had already been made and stored elsewhere and if he were caught, the lictores would sew Tarquinius in a sack and drop him in the Tiber.

In the event a week in the city had been enough. The Etruscan had not known anyone there and lodgings were filthy and expensive. Slightly at a loss, Tarquinius headed south on the Via Appia. Ten miles from the city, he paused by a roadside well to slake his thirst. A group of legionaries were resting under some trees, their javelins and shields stacked nearby. Soldiers were a common sight on the roads, marching to join their units, being sent on engineering duties or heading to war. Despite his training, Tarquinius still struggled not to hate their very existence and what they stood for. It was such legionaries who had crushed the Etruscans centuries before. But his emotions were well hidden as he leaned back against a thick trunk, chewing on a piece of bread and cheese.

Seeing Tarquinius' wiry build and the axe he had unslung from his back, the centurion strolled up and asked him to enlist. Rome was always on the lookout for men who could fight. With a smile, the Etruscan had complied. It seemed the most natural thing in the world to join the force which had been responsible for the subjugation of his people. He had been expecting it.

After two months of hard training, the legions took Tarquinius to Asia Minor and the third war between Rome and Mithridates, the King of Pontus. There the general Lucullus, a former right-hand man of Sulla's, had been fighting for three years. By the time the haruspex arrived, Lucullus had successfully vanquished Mithridates, forcing the king into neighbouring Armenia, where he licked his wounds under the protection of its ruler, Tigranes. Mithridates was still a free man. And as Rome knew from previous bitter experience, this meant the conflict was not over.

Rebuffing all offers of friendship, Tigranes refused to hand over Mithridates, which made him fair game in the general's eyes. Without hesitation, Lucullus led Tarquinius and his legions into Armenia. Battle was joined near the capital city of Tigranocerta. Although vastly outnumbered, Lucullus had crushed the Armenian forces, winning one of the most stunning victories in the Republic's history. Tens of thousands of the enemy were killed. Tarquinius fought with great distinction, helping to turn the enemy flank at a crucial stage in the battle. Using the Roman gladius when in formation, the young soldier switched to his battleaxe when pursuing the Armenians from the field. Nearby legionaries watched in awe as its iron blades flashed through the air, carving men in two. Tarquinius' reward was a promotion to tesserarius, the junior officer in charge of the guard in each century.

He smiled at the memory. Once Tarquinius' centurion had realised that the new tesserarius was capable of filling in the complex duty rosters on his own, he had offloaded large amounts of paperwork on to him. Soon Tarquinius was requisitioning supplies, calculating the men's pay and ordering new equipment.

Meanwhile, Mithridates had escaped yet again. Returning to Pontus, he raised new armies and defeated the local Roman forces there. Bogged down in Armenia, where he was now fighting a guerrilla war, Lucullus had been powerless to respond. To make matters worse, mutiny broke out among his own troops, who by now had been on campaign with him for six long years. Like all legionaries, they had endured harsh discipline and constant danger for little pay. During another long, cold winter under canvas, rumours arose about the generous treatment that Pompey's veterans had received. Despite the efforts of Tarquinius and the other officers, they swept through the legions. And fuelling the discontent was an arrogant and disgruntled young patrician called Clodius Pulcher. He was Lucullus' brother-in-law and Tarquinius had disliked him on sight. Sending his troublesome relation packing, Lucullus dragged his mutinous army to Pontus by sheer force of will, but was no longer able to trust it in combat against Mithridates.

While there was little actual resistance left in the area, no complete victory had been obtained. In situations like this, Rome was merciless.

Pompey Magnus was immediately dispatched to the rescue with the largest force ever sent to the east. Upon the newcomer's arrival, Tarquinius watched with the rest of the soldiers as Pompey stripped Lucullus of both his command and his legions, reducing him to a private citizen. It was a demeaning end for the able general.

Pompey swiftly mopped up the last pockets of resistance, driving Mithridates into the hills, a broken man. Armenia became a new Roman province, Tigranes a mere client king. Peace was restored to Asia Minor and the wily Pompey took all the credit. By this time, Tarquinius had spent four years in the legions. It had been a surprise to find that military life suited him. The camaraderie, the foreign languages and cultures, even the fighting provided the young Etruscan with much more than his former life on the latifundium. Or so he had thought. Since joining up, he had avoided the few chances to perform divinations that had come along, even choosing not to study the weather patterns.

First he had tried to explain it as a way of keeping a low profile, but finally Tarquinius realised that it had all been an attempt to forget his grief, to pretend that Olenus had not gone for ever. This revelation had made the Etruscan desert the army, determined to rediscover himself. Leaving his unit without permission was a crime punishable by death, and had instantly made Tarquinius a fugitive. This knowledge did not trouble him. As long as he did not draw attention to himself, the haruspex knew that he could pass virtually anywhere without being detected. His disappearance would cause little fuss: he had been just another of the rank and file in Rome's legions.

And so Tarquinius visited the temples of nearby Lydia, seeking evidence of links with the Rasenna, his people. He found little more than the occasional shrine to Tinia and a few crumbling tombs. This was enough to prove that the Etruscans had lived there, but not whether they had previously come from somewhere else. Unable to draw himself away from the Mediterranean yet, the young haruspex journeyed to Rhodes and encountered the great philosopher Posidonius, whose opinion on the ascendancy of Rome had interested him greatly. Visits to North Africa and the ruins of Carthage followed, then Hispania and Gaul. Always he took great care to avoid military camps and the men who populated them. Rome sent its soldiers all over the known world, and even in far-flung outposts it was remotely possible he might encounter someone who knew him as a deserter.
