extraordinary care, to perpetuate the memory of a dozen nonentities. Whoever the Twelve were, they represented personages of some importance in the history of Comagrave.
It was the AAnn Riimadu who had first noticed that the enormous, solemn eyes of the graven icons were aligned on a level with the top of the escarpment. It was he who had theorized that the pupilless orbs were each and every pair subtly positioned so that they all focused on approximately the same spot—the one where Cullen’s crew was presently engaged in exploration. Cullen owed the AAnn a debt that would be hard to repay. At the very least, they would share in the subsequent fame and profit of any discovery.
Riimadu was the only AAnn attached to the project. When he was not on site, Cullen missed the alien’s expertise. Like all his kind, the AAnn exoarcheologist displayed an instinctive feel for the makeup of the ground. Adopting his suggestions had already saved the team days of hard work. With most of the busy crew untroubled by the AAnn scientist’s presence from the start, one concern of Cullen’s had been removed early in the process of excavation.
He did have to be careful to keep Riimadu and Pilwondepat apart. Though diplomacy was not a province of his expertise, Cullen knew enough of the traditional enmity that existed between AAnn and thranx to see to it that the two resident alien researchers encountered one another as infrequently as possible. Unlike the AAnn, who took an active part in the excavation, Pilwondepat was present as an observer only, on behalf of several thranx institutes. They had as much interest in ancient races as did humankind, but Comagrave was not to their liking. Though humans could survive and even prosper on a desert world, to the thranx it was an exceedingly uncomfortable place to be.
While humans had to worry only about sunburn because of Comagrave’s comparatively thin atmosphere and take an occasional slug from a bottle of supplemental oxygen, and while Riimadu strolled around in perfect comfort, poor Pilwondepat lumbered about burdened by all manner of gear designed to supply him with the extra oxygen thranx required, as well as special equipment to keep his body properly moist. To a creature who thrived in high heat and even higher humidity, the climate of Comagrave was withering. Unprotected and unequipped, a thranx like Pilwondepat would perish within a few days, shriveled like an old apple. That was assuming it could keep warm at night, when surface temperatures dropped to a level tolerable to both humans and AAnn but positively deadly to a thranx.
So Pilwondepat was not comfortable with his assignment. He kept to his specially equipped portable dome as much as possible and only emerged to take recordings and make notes. When he spoke, it was with difficulty, through a special unit that covered his mandibles and moistened the air that flowed down his throat. Cullen felt sorry for him. The eight-limbed exoarcheologist must have done something unpopular to have come to a world so disagreeable to his kind.
As he turned to head back to camp, Cullen could feel the immense green-black bulges of the eyes of the Twelve drilling into the back of his neck. If only they could speak, he thought. If only they were not made of stone. And if only the Sauun had left some surviving record of what had happened to their civilization. It was such riddles that drove curious men and women to willingly endure harsh conditions on isolated outpost worlds. It was what had driven Cullen Karasi from a successful family business to the study of ancient alien civilizations.
The resolution to all the great unanswered questions lay somewhere on Comagrave, he was certain: buried in an abandoned city, secreted within a protected metal vesicle, locked in the overlying lines of incredibly complex Sauun code that Cullen’s colleagues working elsewhere on the planet had not been able to fully decipher. The first requirement of a good
