Perhaps his status was that of a prisoner, but Shann was too tired to press for an explanation. He was content to be left alone in the unusual circular, but roofless, room of the structure to which they had brought him. There was a thick mat-like pallet in one corner, short for the length of his body, but softer than any bed he had rested on since he had left the Terran camp before the coming of the Throgs. Above him glimmered those patches of light symbolizing the lost stars. He blinked at them until they all ran together in bands like the jeweled coils on Warlockian bodies; then he slept--dreamlessly. The Terran awoke with all his senses alert; some silent alarm might have triggered that instant awareness of himself and his surroundings. There had been no change in the star pattern still overhead; no one had entered the round chamber. Shann rolled over on his mat bed, conscious that all his aches had vanished. Just as his mind was clearly active, so did his body also respond effortlessly to his demands. He was not aware of any hunger or thirst, though a considerable length of time must have passed since he had made his mysteriously contrived exit from the outer world. In spite of the humidity of the air, his ragged garments had dried on his body. Shann got to his feet, trying to order the sorry remnants of his uniform, eager to be on the move. Though to where and for what purpose he could not have answered. The door through which he had entered remained closed, refusing to yield to his push. Shann stepped back, eyeing the distance to the top of the partition between the roofless rooms. The walls were smooth with the gloss of a sea shell's interior, but the exuberant confidence which had been with him since his awakening refused to accept such a minor obstacle. He made two test leaps, both times his fingers striking the wall well below the top of the partition. Shann gathered himself together as might a cat and tried the third time, putting into that effort every last ounce of strength, determination and will. He made it, though his arms jerked as the weight of his body hung from his hands. Then a scramble, a knee hooked over the top, and he was perched on the wall, able to study the rest of the building. In shape, the structure was unlike anything he had seen on his home world or reproduced in any of the tri-dee records of Survey accessible to him. The rooms were either circular or oval, each separated from the next by a short passage, so that the overall impression was that of ten strings of beads radiating from a central knot of one large chamber, all with the uniform nacre walls and a limited amount of furnishings.
