Aidan had spent the rest of that morning hoping that Warhawk would return. Of course, she had, proving to be one of the coolest, most successful hunting falcons in Aidan's sibko.

But that was long ago. Today, stepping onto the ground of the training site, tension overwhelmed him. On his side, on the side of the sibko, there was closeness, trust, the answering of needs. On the other side, on the side of the training officers, there was indifference, danger, contempt. However, there was also—in the occasional sidelong glance and in a certain bodily stiffness—a sense of the enemy ready to spring.

Aidan looked over at Marthe, found her staring at him. Though her eyes were calm, he knew her well enough to perceive in the uneasy set of her full-lipped mouth (shaped so much like his) that she was just as apprehensive.

Sibkos rarely met their genetic donors. At the time the first ilKhan, Nicholas Kerensky, was instituting the first genetic programs, theorists warned him that contact between donors and their sibko children could cause dangerous influences. They were especially wary of what they called unhealthy parental inclinations. Such feelings, they advised, had to be eliminated so that the genetically created warriors would not suffer the personality complications and character flaws that could so easily lead to the mistakes that lost battles and failed whole campaigns. By law the donors must be the best warriors society could offer. The best warriors should, they reasoned, not even want to see their sibspring (a linguistic corruption of "sibling offspring").

Though everyone in the sibko had the same genetic background and resembled one another, Aidan and Marthe looked more alike than either of them resembled any of their sibkin. They were the only ones who had the high forehead tapering down to a narrow chin, a shape akin to a perfect triangle. It was said the look came from their maternal side, and was the famous appearance of Star Commander Tania Pryde, many of whose combat and sporting exploits were excitingly recorded in Clan Jade Falcon annals. She was still among the Blood-named, but like all warriors who had reached the age where custom dictated they must retire from combat, she was fulfilling a noncombatant assignment somewhere or retired into another caste.

Less was known about Galaxy Commander Ramon Mattlov, the paternal contributor of the genes for Aidan's sibko. Rumor had it that his exploits were as impressive as Commander Pryde's, but the accounts had somehow not found their way into Clan or sibko lore. Aidan had been told that he and Marthe resembled Mattlov in their height and slimness. They were the tallest members of their sibko, with Marthe topping Aidan by only a few centimeters.

However, the characteristic that really set off the pair was their eyes—blue as the summer sky on the planet Circe and just as deceptive. As a Circe storm could seem to descend on the planet from nowhere, a swirling tempest preceded only by the slightest change in the serene skies, the calmness in the eyes of Aidan and Marthe when confronted by opponents was the lull that preceded their storms. That serene moment before they sprang into action often gave them the edge against an adversary of equal skills.

Aidan shivered. Even in the thick garments he wore, the harsh wind blowing across the plain made him feel exposed. The other members of his sibko appeared to be shivering, too. They had been instructed that the only clothing they could bring to training camp was what they wore to the landing site. Some of Aidan's sibkin had put on a couple of extra layers; now he wished he had, too. The cold air discovered any ingress into clothing, any place where the material did not quite meet the skin, then rushed in to thoroughly chill every epidermal surface.

"I do not trust any of those non-kin," said Bret, the smallest of the group. "Non-kin" was a term that differentiated their sibko from other sibkos and, for that matter, anyassembly of people outside the sibko. These unkempt, ill-dressed, indifferent officers, for example.

Bret's smallness had seemed to guarantee his early elimination from the sibko, but nobody had counted on his tenacity, courage, and the discipline that had made him exercise for hours every morning. Now he had a strong and muscular body, and the others relied on him for leadership, as much as fiercely independent sibkin could accept anyleader.

"They have planned something for us."

"What, Bret?" Marthe said.

"I do not know, but based on how vicious and unfeeling those who will train us are said to be, I suspect their casual indifference right now is a fraud to hide something devious instead."

"I doubt they will make us stand here for long," Aidan commented. "It would not be Clanlike."

"Clanlike? Are you being sarcastic?" Bret asked.

He was, but Aidan did not want Bret to know that. Bret, who had no concept of the humorous, often commented that Aidan treated life too lightly. The smaller boy had been so intent on his own survival in the sibko, his own proof of kinship with the others, that he never understood a joke. Around a campfire, on hunting expeditions, his laughter always rang false, the laughter of a serious person trying to blend in with others by following their ways. The only jokes he ever told were ones he had heard from others. His nervous manner and the catches in his voice when he delivered punch lines made his listeners doubt his understanding of the joke's humor. The sibko needed Bret's shrewdness and quick decisions at those times when the entire group was being tested, so they excused his lack of humor.

"Neg," Aidan responded. "I am being factual. We are not often allowed relaxation, quiaff?"

"Aff. You know what I think? I think they are testing us right now. See the sidelong glances? They are assessing us, I am sure."

"And at the same time agitating us, quiaff?" Marthe said.

"We should try to look calm," Rena said. "Show we are ready for them, ready to be warriors." Rena was unusual among Aidan's sibmates. Though a bit overweight, like all the survivors of the arduous customs, testings, and retestings of a Clan upbringing, she was in good physical condition. Rena liked to use her unimposing appearance to catch people off guard. She could flip an attacker over her well-muscled back, then wrestle him to the ground faster than anyone else in the sibko. The wrestling was often a prelude to coupling, which she carried out with a similar athleticism. Aidan often let himself be tossed by her, in prospect of having the painful blows evolve into amorous caresses.

"I believe Rena is right," said Bret. "Best to ignore them. How about a team-tussling session? You all up for it?"

There was immediate agreement among the sibko's dozen members. Automatically splitting into their usual three teams, they squared off. Team tussling was both an exercise and a game that, Aidan had once noticed, harmlessly ritualized the kind of grand melee that occurred during a Trial of Position.

Team tussling had developed naturally out of the sibko's intense gymnastic competitions. Once any such activity started, all members of the sibko wanted to be the best at it. In a tussle, they used acrobatic talents along with the combat skills they had been learning, it seemed, since they were trying to kick their way out of their cradles.

The ritual began ceremoniously. Two members of each team formed a "chair" with their hands while another stood on or sat in it. Aidan was certain this beginning had originated from falconry. In a team tussle, the competitors were launched just like the birds. Bret stood on the surface offered by his team's quartet of thinly gloved hands, then his holders hurled him forward. He executed a single flip in the air, landing in front of Rena, who was thrown forward from a sitting position, rolled into a somersault, and then landed at Bret's feet just as he came down.
