of the time. So we started to exchange information. We were doing fine, talking physics and linguistics and getting into biology and social structure and philosophy. Then one evening the two of them went off to their ship. Next morning they didn’t come out. They’ve emerged only for short intervals ever since. And they will no longer swap information with us.”
Gilden was nodding agreement, but he was having trouble absorbing information. Even without the alien Sigil, Lucidar provided an overload of strangeness. Gravity, sun, air, exotic flora and fauna. People. The gravel-voiced Bravtz’ig—the nearest that Gilden could come to his name—was tall and broad enough to have qualified as a giant on Earth, but here he didn’t draw a second glance. It was tiny Derli and Gilden himself who would make the Lucidar freak show.
Alien world, alien thoughts. He stared out of the window of the spaceport tower, to where the Sigil ship was visible as a far-off speck of pearly white.
To penetrate its shields, of unknown nature and number, without leaving evidence of your presence. To plumb the impermeable hull’s deepest secrets . . .
He forced his attention back to the conversation. Bravtz’ig was still talking. What had he just missed? Derli, sitting at his side, had a recorder. Was it running? He would need to review this meeting later.
She gave him a private smile and a raised eyebrow. She knew! Knew he had been observing her with the voyeurs. He was convinced of it. Valmar must have told her. And she didn’t mind . He had a sudden voyeur flashback, a memory of Derli sitting naked and straight-legged on the bed. She was arching her back to reveal delicate pink-nippled breasts, then bending far over to massage overtaxed thigh muscles. Long amber tresses tumbled forward to hide her flat belly and pubic thatch. Had she done that deliberately, knowing he was watching?
Once again he had to fight his way back into the present. What was happening to him? It must be pure travel fatigue. For the past day and a half he had found himself unable to sleep, his head pulsing with thoughts of Valmar Krieg’s prophecy about the challenge of the Sigil.
While he had been daydreaming, another of the Lucidar group had produced surround-videos of the Sigil couple, made not long after their original landing. Now their display was beginning.
Any single element of data about the aliens might be the crucial one. Gilden had seen videos of the two Sigil, but these were much more revealing. He studied them closely, knowing as he did so that he would review them again many, many times. The suits worn by the aliens concealed everything but broad general features. He could see that both Sigil were similar in morphology, bipedal and with bilateral symmetry. The legs were attached close to the middle of the forward-curving torso, and not far above them two long arms emerged at right angles to the body. The dark, hairless head formed a broad cone above a thin neck and ended at the front in a prominent black muzzle.
There were certainly differences between them, but the main surprise was the disparity of sizes. One Sigil towered high over its smaller companion and was at least three times the bulk. Gilden assumed that the huge Sigil must be the female, because of the loving deference and exaggerated care with which it was treated by its diminutive partner. Then he thought of gentle Derli, and Valmar Krieg’s indifferent brutality, and wondered if he had things exactly backward.
“Sexual dimorphism.” Derli spoke softly, more to her recorder than to Gilden or anyone else. “A substantial size difference between the sexes. Common among certain arthropods and mammals with harems. However, analogy with existing Terran forms is more likely to be misleading than helpful. The presence of just one of each of the Sigils argues against multiple mates.”
Bravtz’ig was speaking again. “The Sigil told us—when they were still telling us anything—that a
