Grouped between them now were the players of the drama. One of the Warlockian witches, her gem body patterns glittering in the sunlight, was walking backward out of the sea, her hands held palms together, breast high, in a Terran attitude of prayer. And following her something swam in the water, clearly not another of her own species. But her actions suggested that by some invisible means she was drawing that water dweller after her. Waiting on shore were two others of her kind, viewing her actions with close attention, the attention of scholars for an instructor. "Wyverns!" Shann looked inquiringly at his companion. Thorvald added a whisper of explanation. "A legend of Terra--they were supposed to have a snake's tail instead of hind legs, but the heads.... They're Wyverns!" Wyverns. Shann liked the sound of that word; to his mind it well fitted the Warlockian witches. And the one they were watching in action continued her steady backward retreat, rolling her bemused captive out of the water. What emerged into the blaze of sunlight was one of those fork-tailed sea dwellers such as the Terrans had seen die after the storm. The thing crawled out of the shallows, its eyes focused in a blind stare on the praying hands of the Wyvern. She halted, well up on the sand, when the body of her victim or prisoner--Shann was certain that the fork-tail was one or the other--was completely out of the water. Then, with lightning speed, she dropped her hands. Instantly fork-tail came to life. Fanged jaws snapped. Aroused, the beast was the incarnation of evil rage, a rage which had a measure of intelligence to direct it into deadly action. And facing it, seemingly unarmed and defenseless, were the slender, fragile Wyverns. Yet none of the small group of natives made any attempt to escape. Shann thought them suicidal in their indifference as fork-tail, short legs sending the fine sand flying in a dust cloud, made a rush toward its enemies. The Wyvern who had led the beast ashore did not move. But one of her companions swung up a hand, as if negligently waving the monster to a stop. Between her first two digits was a disk. Thorvald caught at Shann's arm. "See that! It's a copy of the one I had; it must be!" They were too far away to be sure it was a duplicate, but It was coin-shaped and bone-white. And now the Wyvern swung it back and forth in a metronome sweep. Fork-tail skidded to a stop, its head beginning--reluctantly at first, and then, with increasing speed--to echo that left-right sweep. This Wyvern had the sea beast under control, even as her companion had earlier held it.
