"Na. He's nae a joker. Noo our Kraulshavn. 'Kay. Waggle thae a' th' lad. In yon room thae may be't a wee haunt."
"Ghosts?" Even Sorensen was incredulous at that. Kraulshavn signed back what was a blatant suggestion where Alex could put his "wee haunt."
Alex just shrugged. "Aye. Ye be't doubters. But th' Tahn hae tales thae'll kink y'r curlies."
With that, he walked inside. Despite their strongly expressed doubts, Sorensen and Kraulshavn hesitated a long moment before they followed.
Kraulshavn had particular reason to hesitate.
Like any reasonable and sophisticated adult Struth, Kraulshavn viewed stories of the spirit world with imperious amusement, as something to look down one's beak at. Even so, ghost stories were an important and ancient signing tradition in his society. Nestlings barely able to put a few symbols together were told simple tales of ghastly elegance. In the deep past, fear of the unknown had been a valuable tool for a hen to keep her featherless, spindly hatchlings safe.
The Struth had originated on a barren and hostile world that to a nervous observer might have seemed to be entirely populated by creatures with fangs and claws and talons and sharp beaks. That was just true enough to require some fairly tricky skills to avoid being on someone else's menu.
In Struth prehistory, they had once been a species facing extinction. Originally beings of the air, they were a little bit too large to hide and too small to defend themselves. The Struth were also handicapped by poor hearing—limited to the ultrafrequency sounds the leaders and guards of the rookeries used to guide their brothers and sisters. The advantage of that was they could not be heard by any potential enemies. Unfortunately, that meant the Struth also could not hear said enemies approaching.
The Struth were down to a few great rookeries when they finally fled to a small subcontinent. It was a place of small animals with sweet flesh, luscious fruits, and no natural enemies at all—a Struth paradise. And as contented Struth generations passed, they became much larger and heavier and lost the ability to fly. Their small wing claws developed into graceful feathered "hands," good for mutual grooming, plucking fruit, wielding a large stick or rock to fell game, and, more importantly, speaking.
Paradise, however, could not last forever. Maintaining a large rookery in their new homeland became quickly impossible as the sheer size of the Struth suggested a brighter future in small cooperative groups that would put far less stress on the food supply. That also meant that a sophisticated communication system was essential.
Signing was born. At first it was limited to a few basics: Tasty creature under rock. You lift. I take. We share. Soon, however, it became a swift and complex language. A superior signer had greater status than a Struth with a beautiful tail-feather display. Eventually, a Struth philosopher could collapse the most intricate idea into a few symbols of great simplicity. The gentle Struth were on the verge of evolving their signing language into written form when disaster struck.
A land bridge had formed between their paradise and a much greater landmass. At first only a few weaker animals fled across it. They were soon followed by a trickle and then a flood of grazing creatures. The carnivores were right behind. The Strum were easy prey. After thousands of years of relative safety, they were a top-of-the-menu item again. Once again they faced extinction.
But that time they had greater resources to fall back on. The two key talents they had developed post migration were cooperation and language. The Struth split into even smaller groups. They learned to build their nests in the most difficult terrain. They formed two-Struth teams to gather food. That proved to be an ideal number with which to deal with any enemy. One Struth would always be at watch while the other worked. If escape was impossible, the two of them together could kill the attacker.
Smaller rookeries, however, meant that the hatchlings had to be left unguarded for long periods. The question was how to keep the young in their safe nests. The answer was simple: Scare the clot out of them. The ghost story was invented. Struth tales of the spirit world always involved a young hatchling who ignored the warnings of his parents and more cautious siblings and ventured out of the nest. He was always eaten. A favorite villain was the Talon Thing that swooped out of the sky and carried away the little Struth to its own nest, where smaller Talon Things waited to eat the little Struth alive. Another was Big Fang. That beast, it was said, hid in the brush all day, waiting for groups of disobedient Struth young. Big Fang would catch them at play, quickly eating his fill and then hamstringing the others so they could not run away. Big Fang could then seek out his pack mates and return for a feast.
The ghost stories worked. The hatchlings stayed in their nests until they were old enough to bond with other Struth. Eventually the Struth grew tired of hiding in rocky hills from creatures they had realized were not nearly as bright as themselves. The Struth came out of the hills and began killing the carnivores. They killed them until there were no more left. Then they crossed the land bridge and began killing all over again. In two centuries, the Struth were kings of their small planet. Unlike many other races on countless other worlds, when the Struth had run out of common enemies, they did not begin seeing a replacement among their own numbers. Instead, they returned to being the peaceful Struth again, whose greatest joy was in the elegant symbols—both written and signed—that they used to communicate with.
When they were finally discovered by the Empire, the Struth language had reached the giddy heights of the purest of pure maths. Their computer hardware, for instance, was primitive compared with Imperial standards. But the programs they wrote were so simple that they barely taxed the capacity of the most dim-witted Struth machine.
As software artists, they were instant hits, commanding premium salaries and the most luxurious perks. There was one requirement, however, written into every Struth contract with the outside. They must always be hired in twos. Otherwise, they would have no one else to sign with. Struth had been known to die of loneliness.
Kraulshavn was not near death when Sorensen found him at their previous prison camp. But day by day he was wasting away. Kraulshavn had been working as a civilian on an Imperial military contract when the Tahn had invaded. His companion was killed in the first fighting. Somehow Kraulshavn had survived.
Sorensen thought the little Struth was the most mournful being he had ever met. Sorensen's great calculating brain and Kraulshavn's elegant way of thinking made them natural friends. It was easy for a being like Sorensen to learn the signing language, and soon he was wagging away with Kraulshavn like a native Struth. Kraulshavn began eating again and taking an interest in life.
They soon teamed up permanently and made one nearly successful attempt to escape. They were just getting ready for another when they were transported to Koldyeze.
When Kilgour found them, he knew instantly that they were the solution to a seemingly impossible problem. What the organization needed more than anything else was a computer capable of reducing endless years of calculating drudgery to a few hours. With such a computer, the chances of escape would soar geometrically.
Sorensen and Kraulshavn had assured him that the solution was simple. All they had to accomplish was two things. Step one: Reinvent the chip. With that, they could build a tiny-brained computer. Step two: Invent a language that said little brain could deal with without blowing its circuits.
When Alex stumbled upon the large room with the tricky sliding gear lock, he was pretty sure that among its contents was the answer to step one.
